00:00Today on This Old House.
00:02Homeowners decide to change the aluminum siding,
00:04and I'm going to be honest with you, I'm not sorry to see it go.
00:07Then we'll see what happens to that siding after it leaves the job site.
00:12And we're installing a new i-beam.
00:14We're going to jack it up and bolt it in place.
00:50Hey there, I'm Kevin O'Connor, and welcome back to This Old House
00:53and to our project here in Needham, Massachusetts,
00:55where Charlie and his crew are well underway renovating our home,
00:59built in 1896 for our family of five.
01:03Now, last time we were here, we actually had three concrete pours
01:08to make up a new foundation for the addition going off the back of this house.
01:13And you can see that the addition has now been framed,
01:16and some of the sheathing has started to go on as well.
01:21The addition spans three levels, basement, first floor, and second floor,
01:25and each level is going to add about 200 square feet, 600 in total.
01:30In the basement, the new space they want to use for a home gym,
01:35and they wanted that space to be connected to the existing basement.
01:39And that means that we had to actually cut through the foundation,
01:43new pour and old rubble stone.
01:45So, our concrete cutting specialists came in,
01:48and they had four huge blades ranging from 32 to 54 inches.
01:53They made our cuts, and then when they were done,
01:56Mark McCullough showed up with some mortar, some hand tools,
01:59and he just sweetened up that rubble stone foundation
02:02so we had a nice, clean opening for a new door,
02:05which they decided to put right where there was an old window
02:08because there was an existing header there,
02:11and, well, why not use it?
02:12Now, the 200 additional square feet here on the first floor
02:16is going to be used to push the kitchen and the family room out towards the back,
02:20making them a little bit bigger,
02:22and they're going to add a new entryway into a proper mudroom and a powder room.
02:29On the second floor, the additional 200 square feet
02:32is going to be used to make the primary suite bigger
02:35as well as making one of the kids' bedrooms a little bigger as well.
02:41Now, there's been a scope change.
02:42The homeowners have recently decided that they want to replace all of these windows,
02:48not something they originally had planned,
02:49but the more they thought about it, they figured they had to go.
02:52They're over 30 years old.
02:54They're not the greatest windows, and they figured that they could do better.
02:56Another thing they decided to do was have the aluminum siding taken off.
03:02They don't like looking at that.
03:04Underneath, there are some wood shingles.
03:06Eh, you know, they're not in terrible shape,
03:07but those are going to have to be addressed,
03:09but they definitely wanted to get rid of the aluminum,
03:11so we'll take care of that today.
03:14And last week, Charlie, while he and his crew were demoing inside,
03:18first floor all the way up to the second,
03:20actually bumped into a red flag,
03:22one that required Charlie to pull in our abatement specialist,
03:26and the two of them got together
03:27to figure out how they're going to deal with that problem.
03:31Well, Ron, you can see we're well underway in our demo,
03:34and this was our dining room,
03:35which is going to be our new living room.
03:37And this entire wall's coming down,
03:39so we started to gut the walls and the ceiling.
03:41There was even a china cabinet here
03:42that we took apart, and we're going to repurpose later.
03:45And taking the plaza down,
03:47we see this ductwork,
03:48and it looks like asbestos to me.
03:50What do you think?
03:51Yeah, it sure does.
03:52Yep.
03:52You could have it tested to confirm,
03:54but just looking at it,
03:55judging from the vintage of the ductwork
03:58and the color, the texture,
04:00that's almost certainly asbestos.
04:02So asbestos was really like the wonder material
04:04back in the day,
04:05so they just knew it would never decay.
04:07It didn't conduct electricity.
04:09It's very impervious to rot, water,
04:12and heat.
04:13It's a great heat insulator, too.
04:15They use it in glues and mastics
04:17because it also has a little fiber to it
04:19that makes it stronger so it resists cracking.
04:22So you're going to see it
04:22in a lot of materials in homes
04:24because it was inexpensive,
04:25it was plentiful, easy to work with,
04:27and it was very, very durable.
04:28But now we know that it is hazardous.
04:30Back in 1971, the EPA Clean Air Act
04:32identified asbestos as a hazard.
04:35So it's been a long time.
04:36So then it started to get rolled back.
04:38It's been used in so many processes.
04:39It's taken a long time
04:40to get it out of our world.
04:43And it's still in some building material.
04:46So you have to be careful even today.
04:48Wow.
04:48So the best thing to do
04:49would be just to take these ducts right out.
04:51You have this section right here,
04:52which is pretty easy to get to.
04:54And coming up over here and across there,
04:57even though that's not necessarily
04:58going to be impacted by the project
05:00other than just putting new ceiling up,
05:02that's falling apart.
05:03That's what's called friable.
05:05It means it could create dust.
05:07It could be pulverized.
05:07And it's going to create a hazard
05:08for your workers
05:09and ultimately people living here.
05:11So you want to get that taken care of.
05:13That has to come out anyway
05:14because that's our delivery system
05:16for that vent up there.
05:18So that's coming out
05:19because the wall is going to be gone.
05:20Right, right.
05:21So you can take it out anyway.
05:21You don't have to do anything beyond that
05:23because by regulations,
05:24you just have to take care of the asbestos
05:26that's actually being impacted by the project.
05:28If there's something in another part of the house,
05:30in the basement or up in the attic,
05:31not being impacted by this project,
05:33it can stay.
05:34Ron, if you had a customer
05:35that wanted to leave the duct work
05:36but only remove the asbestos,
05:38what's the next step
05:39to make sure the duct work is clean?
05:42At the end of any of these projects,
05:44even a big renovation project,
05:45it's a good idea
05:46to do a duct cleaning process.
05:48You've got to clean these ducts.
05:49You've got to run agitators down them
05:50and clean them all out.
05:52And there's a lot of contaminants
05:53from mold spores, dirt, dust,
05:55whatever you want,
05:57plus probably some asbestos.
05:59So having that duct cleaning process
06:01when the project is all done,
06:02you get yourself nice, clean, safe ducts.
06:05And you'd be comfortable with that?
06:06Sure, yeah.
06:07All right, well, that's great.
06:08Well, it's all on you now.
06:09So tell me your next steps.
06:12Our reason for existence
06:13is to contain the hazards.
06:17Protect the workers first.
06:19They're going to first put
06:20on their protective equipment.
06:22We've got to create a bubble on isolation.
06:24You've seen them before.
06:25We've done a few of them for you.
06:27And then everything's going to be sealed up
06:28like the set of ET.
06:29And isolate that work area
06:31to make sure that nothing's getting out.
06:37And one of the most important things
06:39we also do is to set up
06:40what's called HEPA-filtered negative air.
06:42Make sure no asbestos fibers
06:44are blowing around this house
06:46when we're doing our work.
06:48We're going to be using water,
06:49which is called amended water,
06:50which is basically soapy water,
06:52to mist that surface down
06:54as we're removing it
06:55to make sure that we're not breaking apart
06:56this dry, friable asbestos
06:59and making dust just kind of
07:00poof all over the place.
07:02We're going to just take
07:03those ducts out in sections.
07:22We're going to go into these double bags
07:23with special labels.
07:24This is what we're going to wind up
07:25at EPA-certified landfill.
07:45So, Charlie, I noticed aluminum siding
07:47on the far side is down
07:49a little bit off the front as well,
07:50so you made good progress.
07:51Yeah, it only takes a couple hours
07:52actually to strip one side,
07:53so it comes off pretty quick.
07:54So, we're going to start here
07:55with the aluminum that's over
07:57the existing crown molding.
07:59We're going to start with this,
08:00take those off,
08:01and then we'll start removing the siding.
08:02But we're going to be careful
08:04because this aluminum drip edge
08:05is part of the roof system,
08:06and that's staying.
08:07All right.
08:07Tool of choice?
08:08Flat bar and hammer.
08:10Pretty simple.
08:10Okay.
08:11Let's start here first.
08:13It should come off pretty easy.
08:23Taking off all the aluminum siding
08:25was not in the original plan.
08:26What changed the homeowner's mind?
08:28Well, they always thought down the road
08:29they would change the siding
08:30like a phase two,
08:31but once they saw the work
08:32started to get done,
08:34they said, you know what,
08:35let's just do it now.
08:36Yeah.
08:36You know what?
08:37It's actually cheaper to do it now
08:38because we're here.
08:39It's definitely the right to see
08:40for this house.
08:42Right over there
08:43is a wrap aluminum dumpster.
08:45Oh.
08:46So it's a weigh-in-pay system.
08:48They drop it off,
08:49we fill it,
08:49they haul it out,
08:50and they pay.
08:51So just the aluminum
08:52going in that one.
09:26I couldn't resist.
09:27I had to find out
09:28what was going to happen
09:29to our aluminum,
09:30so I have come here.
09:32This is a recycling facility
09:34about 20 miles from our job site,
09:36and it is the first stop
09:38for our aluminum.
09:41It's going to get weighed right there.
09:42That's our dumpster.
09:43That's our siding,
09:44and I'm going to find out
09:46what the rest of the journey
09:48looks like.
09:50First stop's the weigh-in.
09:52Second stop's the dump.
09:59Anthony, Kevin.
10:01How you doing, man?
10:01Nice to meet you.
10:02Nice meeting you.
10:02You've got a busy place here.
10:04It's not busy yet.
10:05Not busy?
10:06No, we get very, very busy
10:08at different times of the day.
10:09Lunchtime rush,
10:10different things
10:10before the end of the day.
10:12All right.
10:13So first off,
10:14how's our pile look?
10:15Looks great.
10:15It's nice, clean,
10:16all aluminum siding,
10:17just what we're looking for.
10:19What happens with this pile now?
10:20So this material,
10:22he's putting it right inside
10:23the hupper of our baler.
10:25There's a gentleman up top
10:26doing the control,
10:27so as he puts a bunch in,
10:29that gentleman will hit the pusher,
10:31and that allows a block
10:32to come over and squeeze it down
10:34to make it more compact.
10:36So they'll do that
10:36a few different times
10:37throughout this process.
10:39And that's a bale of wire coming off?
10:42That's a bale of Romex wire right there.
10:44It'll come out as a finished product,
10:47and then it'll be stored
10:48until we ship it out,
10:49and this specific material
10:51will get shipped up to Canada.
10:53So how do you guys classify aluminum?
10:56Are there different grades,
10:58different types?
11:00As a company,
11:01we probably have about
11:0225 to 30 different commodities
11:04of aluminum,
11:05and that ranges anywhere
11:06from aluminum that has iron,
11:09such as a transmission
11:10or an engine block,
11:13all the way to clean,
11:14mill grade stuff like this here,
11:15or your bare extruded pipe.
11:19And you guys are not going
11:20to push out a block
11:21until all of this,
11:22at least all of this,
11:23is in there, right?
11:24Yeah, yeah, 100 times.
11:27So you guys are sorting
11:28more than just aluminum,
11:29and I'm actually seeing
11:30a lot of people hand-picking stuff,
11:32which surprises me, Anthony.
11:33So the scrap metal
11:35has so many different commodities
11:38and different nuances to it.
11:40So this here is our non-ferrous scale area,
11:42so any customer who has their copper,
11:46their aluminum, brass, stainless steel,
11:48things of that nature,
11:49they'll come up here to get weighed
11:50compared to the iron yard outside.
11:52Right.
11:53And if it has to get cut up,
11:55and process to be upgraded,
11:57it will go into a pile,
11:58and everything else has its own home
12:01within the yard for processing.
12:02What do you mean by upgraded?
12:03So the more purer form of a metal,
12:07the higher value it is.
12:08So you take a piece of copper.
12:10So in order to get a high number one copper,
12:13you need to get rid of any impurity.
12:15So we take this piece here,
12:17and with our shears,
12:18our guys are going to cut off
12:19all the elbows and fittings,
12:21and then you'll get straight runs
12:23of number one copper,
12:23and you'll get little pieces of number two,
12:25which is what we buy it at.
12:26And where are the impurities in an elbow?
12:28So you have your solder joints.
12:30Oh.
12:31Nowadays, a lot of people use ProPress,
12:32or the rubber gasket on the inside of that
12:34as an impurity.
12:36So something like this.
12:37Something like that.
12:38We would just ship that as a number two.
12:39So we wouldn't waste the time
12:41to upgrade a little piece of that.
12:42But when you've got this much,
12:43it's worth upgrading.
12:44100%.
12:45So when you buy this,
12:47you're just paying sort of a flat rate,
12:49and then you decide whether or not
12:51it's worth your time.
12:53In labor.
12:54To chop it up.
12:54To chop it up.
12:55To get it to the next upgrade.
12:57Wow.
12:58Okay.
12:58Let's go see how our aluminum's getting processed.
13:02Oh, look at that.
13:04So it took Charlie and I a couple hours
13:07to get it off the house.
13:08It took you guys about five minutes
13:09to get it into a nice little bale.
13:11So all of our siding went in there.
13:14What do you think this bale weighs?
13:17Average bale of aluminum,
13:18anywhere from 1,000 to 1,200 pounds or so.
13:20Right.
13:21Off to Canada?
13:22Off to Canada.
13:22And then maybe right back to the States
13:24in the form of siding?
13:25Within a few weeks.
13:26Awesome.
13:26So what did we make?
13:30So your can of aluminum weighed 780 pounds.
13:34It was valued at 62 cents per pound
13:37for a tally of $483.
13:40Okay.
13:41Minus the trucking fee,
13:42so you're looking at about $300 cash.
13:43$300.
13:44Can you do any better?
13:46On the next one.
13:48I appreciate it, Anthony.
13:49You guys are awesome.
13:50Appreciate it.
13:56After Ron's crew took care of the duct work
13:58with the asbestos on it,
14:00Charlie's crew came in
14:01and they built those four temporary walls.
14:03One to my left right here
14:04with a second one just directly beneath it
14:06going into the basement.
14:07Another one to my right
14:08with a second one going beneath that one
14:10to the basement as well.
14:11With those up,
14:12we were able to take out this wall right here
14:15that originally separated the kitchen
14:16from the dining room
14:17so that we can open up all of this space.
14:20And with it gone,
14:21we now have to put in a big beam
14:24to support all its weight
14:26so we can take those temporary walls down.
14:28And for that,
14:29we turn to Mr. Silva.
14:30Hey, Pops.
14:30Hey, Kevin White.
14:31Good.
14:32So you fit.
14:33I did.
14:33No problem at all.
14:35A little bump here or there,
14:36but that's not bad.
14:37So a long beam, right?
14:38Yeah.
14:39And I noticed the metal plate back there.
14:40Is that where it starts?
14:41That steel plate right there
14:43is so we can bolt the end of this steel beam
14:45that's going to run in here
14:46into that steel beam.
14:48That steel beam is supported
14:49by the column on that side
14:51and the one on the outside wall.
14:53And so that's going to carry
14:54half of this load right there on that beam.
14:57And the other half is going to end up down here.
14:59About two feet in from this corner.
15:01It's going to be a steel column
15:03to the wooden center bearing beam of the house
15:06and another steel column
15:08and a footing in the basement.
15:09So it's going to carry a lot.
15:10How long are we talking in total generally?
15:1324 feet and a little over four inches.
15:16Okay.
15:16So long beam.
15:17How are we getting that into the house?
15:19Well, we're going to bring the beam
15:20in through the window
15:21and we're going to bring it in
15:22a couple of dolly jacks
15:23that will allow us to move it
15:25and pick it up
15:26and push it right into place.
15:28Okay.
15:28It's a big beam and it's heavy.
15:29It's probably close to 2,500 pounds.
15:31So 20 some odd feet long
15:33and how high are we talking?
15:35The beam's going to be 16 inches.
15:37So it's going to hang down here somewhere.
15:38Right there.
15:39All right.
15:39And it's 11 inches wide.
15:41So we have to make an allowance
15:42to get the beam in
15:43because it's padded with wood.
15:45Now remember, this is an I-beam.
15:46It's got a wide flange at the top,
15:48a centerpiece,
15:49and another flange on the bottom.
15:51We need to pad it with wood
15:53to make the marriage
15:54between the framing
15:56and the steel,
15:57wood to wood connection.
15:59And we're going to make that connection
16:01and we're going to make that connection
16:01with the hanger like this.
16:03This is an old work hanger
16:05so it fits the old joist better.
16:07And we're going to nail it in
16:08and we nail it,
16:09we'll land at a very slight angle
16:11that will draw these up nice and tight.
16:13Then we'll fill these holes
16:14and we won't have any squeaking later on.
16:17Okay.
16:17Looks like a bunch of notches were made.
16:19I got my belt.
16:20I can help you make the last,
16:21what, four or five?
16:21Yeah, we got four or five more to go.
16:23I just squared these down.
16:25What we want to do
16:25is square them down
16:26from the floor above.
16:28So I just hold my square
16:29up against the floor,
16:30line it up with my chalk line,
16:32bring it down,
16:33mark it on each side,
16:35and then we'll do a saw
16:37and make a cut.
16:38Is this coming out?
16:38Yep.
16:39If you get that out,
16:40that'll be good.
16:40It'll make it easier
16:41for us to get the saw in.
17:14Oh, Tommy, you're a beast.
17:16All right.
17:17Now we can get the beam in.
17:18I'll get this cleaned up.
17:33All right.
17:34We just took the beam off the truck
17:35and get it down on the ground.
17:36We got to flip it over.
17:37It's upside down.
17:39Reposition it
17:39and then slide it in.
17:45All right.
17:46The beam's coming in.
17:47They've got it cabled right here
17:50in the center,
17:50so it's doing a balancing act.
17:52They're going to get it in
17:53as far as they can
17:54and then we're going
17:54to reposition the cable.
17:58All right.
17:58They're positioning
17:59one of the jacks.
18:00They want to carry the load
18:01of the end of the beam
18:03right here.
18:03You can see the strap
18:04that's on the end of the beam
18:06that's connected to the load.
18:08And basically,
18:08he's holding the end weight.
18:10They're resting the beam
18:11right here
18:12to take the weight
18:13off of the cable
18:14along with the jack
18:15down the other end.
18:16We're going to roll it
18:17on the jack.
18:26There.
18:26Now you're coming.
18:27Now you're coming.
18:28Now you're coming.
18:30All right.
18:31You can see they get it in
18:32as far as they can go
18:33right now,
18:34the cable right.
18:35Now they've got to
18:35reposition this cable.
18:36They're going to slide it down
18:37and bring it in
18:38a little more.
18:39Oh, oh, oh.
18:44Oh, watch that side.
18:47This wooden beam,
18:48this is the main beam
18:49of the house,
18:50the center beam.
18:51Wooden beams,
18:52old wooden beams
18:52get big cracks in them.
18:54That's called checks.
18:55Now, as long as they're
18:57running with the beam
18:58like they are,
18:59believe it or not,
19:00it doesn't weaken the beam.
19:01So you have a wooden beam,
19:03top and bottom.
19:05It's parallel
19:05because that's how
19:06it comes out of the sawmill.
19:07If you have a check
19:08or a crack that runs down
19:10the side of the beam,
19:11guess what happens?
19:12If there's no pressure
19:13on the part of the post
19:15or the beam,
19:16it will roll down slightly.
19:18That takes my parallel
19:19of the beam out
19:20and gives it a curve.
19:23So what we just did
19:24Yeah, it's going.
19:25is jack this edge
19:27of the beam back up,
19:28closing the check
19:29of the crack,
19:30making it parallel again
19:32so the lally column
19:33would go in.
19:40Oh, let it down.
19:45That should be it.
19:48Okay.
19:49Now we're ready
19:50to put the I-beam
19:51back into place.
19:52We're going to put it in
19:53against here,
19:55get it jacked where it goes
19:56and put the second lally column
19:57in over here.
19:58All that load's getting pushed
20:00down to the footing
20:01that's in the basement.
20:07We're putting some temporary
20:08bracing underneath the beam.
20:10That way we can reposition
20:12the jacks as needed
20:13and make sure everything's safe.
20:17All right, we're almost there.
20:19We've got the beam
20:19up under the floor joist.
20:21Now we have to slide it over
20:23so it goes in the pocket.
20:25So a little bit of finagling,
20:27a lot of safety watching here.
20:29You don't want anything
20:29to break and snap
20:30and come down.
20:32Yes, you know what?
20:34Have him go up a little bit.
20:36Keep going.
20:37There you go.
20:38Go, go, go, go, go.
20:39You've got pressure off.
20:40Yep, yep.
20:40Good.
20:41All right, we're past it.
20:43Yeah, all right.
20:47A little bit of weight there.
20:48Yeah, now screw it.
20:53There you go.
20:57We're doing it, Sam.
20:58We're doing it.
20:59All right, our beam
21:00is in the slot
21:02that we made
21:02all the way across.
21:04Now, one of the problems
21:05that we have to think about here
21:06is because the beam's
21:07got to go up
21:08that much more
21:09on the other end
21:10and still be
21:11about a quarter of an inch
21:12below the subfloor.
21:14But,
21:15when we hit here,
21:16because the house
21:17had a little dip in it,
21:18this dip is going to be pushed,
21:20this beam is going to push
21:21against the underside
21:22of the subfloor tightly,
21:24which means
21:25when it comes time
21:27to put all
21:28of the timber hangers
21:29on the joist,
21:30we're going to have
21:31to jack the joist
21:32individually,
21:34making the space
21:35above the beam
21:36equal along the run.
21:38All right,
21:39he's putting the last nut
21:40on the eight bolts.
21:42Once he gets it caught,
21:43he's going to use
21:44the impact wrench,
21:45tighten them all up.
21:46At the same time,
21:47it may slide the beam
21:48in place.
21:49We'll see.
21:53This is a spud wrench,
21:54probably the one tool
21:55I don't have
21:56until today.
21:59He lines the holes
22:00with this end
22:01of the spud wrench,
22:02then flips it around
22:03to tighten up the bolts.
22:14Nice big beam.
22:15Look at that, huh?
22:16Oh, yeah.
22:16What a difference.
22:17So, what's next?
22:18Well, we have about
22:19six joists
22:19that are really badly damaged.
22:21You have to repair those
22:22and then install the hangers.
22:23And then we can take
22:24the temp walls down
22:24and even the old
22:25exterior wall.
22:26Talk about opened up.
22:27That'll do it, right?
22:28Yeah, absolutely.
22:29All right, so until next time,
22:30I'm Kevin O'Connor.
22:31And I'm Charlie Silva.
22:32And I'm Tom Silva.
22:33For this old house here
22:34in Needham.
22:35Very nice.
22:36Makes a big difference.
22:37Oh, my God.
22:41Next time on
22:42This Old House,
22:43even with our new addition,
22:44we're reusing
22:45the existing HVAC system.
22:47But we're adding
22:48some strategic duct work.
22:50Then we're going to show you
22:51which insulation
22:51we're using
22:52on our roof system
22:53and why.
22:54Oh, boy.
22:55I see an uninsulated roof.
22:58Yeah, HVAC system
22:59lives up there.
23:00Two by six,
23:01rough framing,
23:02no insulation.
23:03And we're getting
23:03back to the basics,
23:05installing a new
23:06double-hung window
23:07into an existing opening.
23:09That's next time.
23:14Give it back.
