00:00Today on This Old House. Homeowners decide to change the aluminum siding and I'm
00:04gonna be honest with you I'm not sorry to see it go. Then we'll see what happens
00:08at that siding after it leaves the job site. And we're installing a new I-beam.
00:14We're gonna jack it up and bolt it in place.
00:30Hey there I'm Kevin O'Connor and welcome back to This Old House and to our project here in Needham, Massachusetts where Charlie and his crew are well underway renovating our home.
00:59Built in 1896 for our family of five. Now last time we were here we actually had
01:06three concrete pours to make up a new foundation for the addition going off the
01:12back of this house and you can see that the addition has now been framed and some
01:17of the sheathing has started to go on as well. The addition spans three levels
01:23basement first floor and second floor and each level is going to add about 200
01:28square feet 600 in total. In the basement the new space they want to use for a home
01:34gym and they wanted that space to be connected to the existing basement and
01:39that means that we had to actually cut through the foundation new pour and old
01:44rubble stone. So our concrete cutting specialists came in and they had four huge
01:49blades ranging from 32 to 54 inches. They made our cuts and then when they were done
01:56Mark McCullough showed up with some mortar some hand tools and he just sweetened up
02:01that rubble stone foundation so we had a nice clean opening for a new door which
02:06they decided to put right where there was an old window because there was an
02:09existing header there and well why not use it. Now the 200 additional square feet
02:15here on the first floor is going to be used to push the kitchen and the family room
02:19out towards the back making them a little bit bigger and they're going to add a new
02:25entryway into a proper mudroom and a powder room. On the second floor the
02:31additional 200 square feet is going to be used to make the primary suite bigger as
02:36well as making one of the kids bedrooms a little bigger as well. Now there's been a
02:41scope change. The homeowners have recently decided that they want to replace all of
02:47these windows not something they originally had planned but the more they
02:50thought about it they figured they had to go. They're over 30 years old they're
02:54not the greatest windows and they figured that they could do better. Another thing
02:57they decided to do was have the aluminum siding taken off. They don't like looking
03:03at that underneath there are some wood shingles you know they're not in terrible
03:07shape but those are gonna have to be addressed but they definitely wanted to get
03:10rid of the aluminum so we'll take care of that today. And last week Charlie while he and his
03:16crew were demoing inside first floor all the way up to the second it actually
03:21bumped into a red flag one that required Charlie to pull in our abatement
03:25specialist and the two of them got together to figure out how they're going
03:28to deal with that problem. Well Ron you can see we're well underway in our demo and
03:34this was our dining room which is going to be our new living room and this entire
03:38walls coming down so we started to gut the walls and the ceiling. There was even a
03:41china cabinet here that we took apart and we're going to repurpose later. And taking the
03:46plaster down we see this ductwork and it looks like asbestos to me. What do you
03:50think? Yeah it sure does. Yep. You could have it tested to confirm but just looking
03:55at it judging from the the vintage of the ductwork and the color the texture
03:59that's almost certainly asbestos. So asbestos was really like the wonder
04:04material back in the day so they just knew it would never never decay. It didn't
04:08conduct electricity. It's very impervious to rot, water, and heat. It's great heat
04:14insulator too. They use it in glues and mastics because it also has a little
04:18fiber to it that makes it stronger so it resists cracking. So you're going to see
04:22it in a lot of materials in homes because it's just it was inexpensive, it was
04:25plentiful, easy to work with, and it was very very durable. But now we know that it
04:29is hazardous. Back in 1971 the EPA Clean Air Act identified asbestos as a hazard.
04:35So it's been a long time. So then it started to get rolled back. It's been used in so
04:39many processes. It's taken a long time to get it out of our out of our world and
04:44it's still in some building materials. You have to be careful even even today.
04:47Wow. So the best thing to do would be just to take these ducts right out. You
04:52have this section right here which is pretty easy to get to and coming up over
04:55here and across there even though that's not necessarily going to be impacted by
05:00the project other than just putting new ceiling up. That's falling apart. That's
05:03what's called friable. It means it could create dust. It could be pulverized and it's
05:08going to create a hazard for your workers and ultimately people living here. So
05:11you want to get that taken care of. It has to come out anyway because that's our
05:15delivery you know system for that vent up there. So that's coming out because the
05:19wall is going to be gone. Right. Right. Take it out anyway. Yeah. You don't have to do
05:22anything beyond that because by regulations you just have to take care of
05:25the asbestos that's actually being impacted by the project. If there's
05:28something in another part of the house in the basement or up in the attic not
05:31being impacted by this project it can stay. Ron if you were a customer that wanted to
05:35leave the ductwork but only remove the asbestos. What's the next step to make
05:40sure the ductwork is clean? At the end of any of these projects even a big
05:44renovation project it's a good idea to do a duct cleaning process. You're going to
05:48clean these ducts. You're going to run agitators down them and clean them all
05:52out and there's a lot of contaminants from mold spores, dirt, dust, whatever you
05:56want plus probably some asbestos. So having that duct cleaning process when the
06:01project is all done you get yourself nice clean safe ducts. And you'd be
06:05comfortable with that? Sure yeah. All right well that's great well it's all on you
06:09now so tell me your next steps. Our reason for existence is to contain the
06:14hazards. Protect the workers first. They're going to first put on their
06:20protective equipment. We've got to create a bubble on isolation you've seen them
06:24before we've done a few of them for you and then everything's going to be sealed up
06:28like the set of ET and isolate that work area to make sure that nothing's getting
06:32out.
06:37And one of the most important things we also do is to set up what's called
06:40HEPA filtered negative air. Make sure no asbestos fibers are blowing around this
06:46house when we're doing our work. We're going to be using water which is called
06:50amended water which is basically soapy water to mist that surface down as we're
06:54removing it to make sure that we're not breaking apart this dry friable
06:58asbestos and making dust just kind of poof all over the place. We're going to just
07:03take those ducts out in sections.
07:04go into these double bags with special labels as we're going to wind up at EPA certified landfill.
07:09go into these double bags with special labels as we're going to wind up at EPA certified landfill.
07:16go into these double bags with special labels as we're going to wind up at EPA certified landfill.
07:23go into these double bags with special labels as we're going to wind up at EPA certified landfill.
07:30so Charlie I noticed aluminum siding on the far side is down a little bit off the front as well so you made good progress.
07:35yeah it only takes a couple hours actually to strip one side so it comes off pretty quick so we're going to start here with the aluminum that's over the existing crown molding.
07:42we're going to start with this take those off and then we'll start removing the siding but we're going to be careful because this aluminum drip edge is part of the roof system and that's staying.
07:49all right tool of choice?
07:50flat bar and hammer.
07:51pretty simple.
07:52okay.
07:53let's start here first.
07:54should come off pretty easy.
07:55yeah.
07:56taking off all the aluminum siding was not easy.
07:58yeah.
07:59taking off all the aluminum siding was not easy.
08:00right here with the aluminum that's over the existing crown molding.
08:02we're going to start with this take those off and then we'll start removing the siding.
08:03but we're going to be careful because this aluminum drip edge is part of the roof system and that's staying.
08:07all right.
08:08tool of choice?
08:09flat bar and hammer.
08:10pretty simple.
08:11okay.
08:12let's start here first.
08:13it should come off pretty easy.
08:18yeah.
08:23taking off all the aluminum siding was not in the original plan.
08:26what changed the homeowners mind?
08:27well they always thought down the road they would change the siding like a phase two.
08:31but once they saw the work started to get done just said you know what let's just do it now.
08:35yeah.
08:36you know what it's actually cheaper to do it now because we're here.
08:38it's definitely the right to sleep for this house.
08:40oh yeah.
08:41right over there is a wrap aluminum dumpster.
08:44oh.
08:45so it's a weigh and pay system.
08:47they drop it off we fill it they haul it out and they pay.
08:50so just the aluminum going in that one.
08:52so just the aluminum going in that one.
08:54so just the aluminum going in that one.
08:59i couldn't resist i had to find out what was going to happen to me.
09:04what was going to happen to our aluminum so i have come here.
09:07this is a recycling facility about twenty miles from our job site.
09:09i couldn't resist i had to find out what was going to happen to our aluminum.
09:16so i have come here.
09:17this is a recycling facility about twenty miles from our job site.
09:23and it is the first stop for our aluminum.
09:24it's going to get weighed right there.
09:25that's our dumpster.
09:26that's our siding.
09:27and i'm going to find out what the rest of the journey looks like.
09:30first stops to weigh in.
09:31second stops to dump.
09:33anthony.
09:34anthony.
09:35anthony.
09:36kevin.
09:37how you doing man?
09:38nice to meet you.
09:39nice to meet you.
09:40you got a busy place here.
09:41it's not busy yet.
09:42not busy?
09:43no.
09:44we get very very busy at different times of the day.
09:46and we're going to get to the next stop for our aluminum.
09:48it's going to get weighed right there.
09:49that's our dumpster.
09:50that's our siding.
09:51and i'm going to find out what the rest of the journey looks like.
09:52first stops to weigh in.
09:54second stops to dump.
09:57anthony.
09:58kevin.
09:59how you doing man?
10:00nice to meet you.
10:01nice to meet you.
10:02you got a busy place here.
10:03it's not busy yet.
10:04not busy?
10:05no.
10:06we get very very busy at different times of the day.
10:09lunchtime rush.
10:10different things before the end of the day.
10:12alright.
10:13so first off how's our pile look?
10:14looks great.
10:15it's nice clean.
10:16all aluminum siding.
10:17just what we're looking for.
10:18what happens with this pile now?
10:20so this material.
10:21he's putting it right inside the hupper of our baler.
10:24there's a gentleman up top.
10:26doing the control.
10:27so as he puts a bunch in.
10:29that gentleman will hit the pusher.
10:30and that allows a block to come over and squeeze it down.
10:34to make it more compact.
10:36so they'll do that a few different times.
10:37throughout this process.
10:39and that's a bale of wire coming off?
10:41that's a bale of Romex wire right there.
10:44it'll come out as a finished product.
10:46and then it'll be stored until we ship it out.
10:49and this specific material will get shipped up to Canada.
10:52so how do you guys classify aluminum?
10:56are there different grades? different types?
10:59as a company we probably have about 25 to 30 different commodities of aluminum.
11:04and that ranges anywhere from aluminum that has iron.
11:08such as a transmission or an engine block.
11:11all the way to clean mill grade stuff like this here.
11:15or your bare extruded pipe.
11:18and your guy's not going to push out a block until all of this.
11:22at least all of this is in there right?
11:24yeah yeah 100.
11:25okay.
11:26so you guys are sorting more than just aluminum.
11:29and i'm actually seeing a lot of people hand picking stuff.
11:32which surprises me Anthony.
11:33so the scrap metal has so many different commodities and different nuances to it.
11:39so this here is our non ferrous scale area.
11:42so any customer who has their copper, their aluminum, brass, stainless steel, things of that nature.
11:49they'll come up here to get weighed compared to the iron yard outside.
11:52right.
11:53and if it has to get cut up and processed to be upgraded it will go into a pile.
11:58and everything else has its own home within the yard for processing.
12:02what do you mean by upgraded?
12:03so the more purer form of a metal the higher value it is.
12:08so you take a piece of copper.
12:10so in order to get you know a high number one copper you need to get rid of any impurity.
12:15so we take this piece here.
12:17and with our shears our guys are going to cut off all the elbows and fittings.
12:21and then you'll get straight runs of number one copper.
12:23and you'll get little pieces of number two which is what we buy it at.
12:26and where are the impurities in an elbow?
12:28so you have your solder joints.
12:30nowadays a lot of people use pro press or the rubber gasket on the inside of that as an impurity.
12:36so something like this.
12:37something like that.
12:38we would just ship that as a number two.
12:39we wouldn't waste the time to upgrade a little piece of that.
12:42but when you've got this much it's worth upgrading.
12:44100%.
12:45so when you buy this you're just paying sort of a flat rate.
12:49and then you decide whether or not it's worth your time.
12:52in labor.
12:53to chop it up.
12:54to chop it up.
12:55to get it to the next upgrade.
12:56wow.
12:57okay.
12:58let's go see how our aluminum is getting processed.
13:00oh look at that.
13:03so it took charlie and i a couple hours to get it off the house.
13:07took you guys about five minutes to get it into a nice little bale.
13:10so all of our siding went in there.
13:13what do you think this bale weighs?
13:15average bale of aluminum anywhere from a thousand to twelve hundred pounds or so.
13:19right.
13:20off to canada.
13:21off to canada.
13:22then maybe right back to the states in the form of siding.
13:24within a few weeks.
13:25awesome.
13:26so uh.
13:27what'd we make?
13:28ah.
13:29so your can of aluminum weighed 780 pounds.
13:34it was valued at 62 cents per pound for a tally of $483.
13:39okay.
13:40minus the trucking fee so you're looking at about $300 cash.
13:43300.
13:44can you do any better?
13:46on the next one.
13:47i appreciate it.
13:48you guys are awesome.
13:49thank you.
13:50appreciate it.
13:55after ron's crew took care of the duck work with asbestos on it.
13:59charlie's crew came in and they built those four temporary walls.
14:02one to my left right here.
14:04with a second one just directly beneath it going into the basement.
14:07another one to my right.
14:08with a second one going beneath that one to the basement as well.
14:11with those up we were able to take out this wall right here.
14:14that originally separated the kitchen from the dining room.
14:17so that we can open up all of this space.
14:19and with it gone we now have to put in a big beam.
14:24to support all its weight so we can take those temporary walls down.
14:27and for that we turn to mr silva.
14:29hey pops.
14:30hey kevin white.
14:31good. so you fit.
14:32i did.
14:33no problem at all.
14:34a little bump here or there but that's not bad.
14:36so a long beam right?
14:38yeah.
14:39and notice the metal plate back there.
14:40is that where it starts?
14:41that steel plate right there is so we can bolt the end of this steel beam.
14:45that's going to run in here into that steel beam.
14:47that steel beam is supported by the column on that side.
14:50and the one on the outside wall.
14:52and so that's going to carry half of this load right there on that beam.
14:56and 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 and 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.
15:15okay. so long beam.
15:16how are we getting that into the house?
15:18well we're going to bring the beam in through the window
15:20and we're going to bring it in a couple of dolly jacks.
15:23that will allow us to move it and pick it up and push it right into place.
15:27okay.
15:28it's a big beam and it's heavy.
15:29it's probably close to 2500 pounds.
15:31so 20 some odd feet long and how high are we talking?
15:34the beam is going to be 16 inches so it's going to hang down here somewhere.
15:38right there.
15:39all right.
15:40and it's 11 inches wide.
15:41so we have to make allowance to get the beam in because it's padded with wood.
15:44now remember this is an I-beam.
15:46it's got a wide flange at the top.
15:48a centerpiece and another flange on the bottom.
15:51we need to pad it with wood to make the marriage between the framing and the steel.
15:57wood to wood connection.
15:59and we're going to make that connection with the hanger like this.
16:03this is an old work hanger so it fits the old joist better.
16:07and we're going to nail it in and we nail it.
16:09we'll lay it at a very slight angle that will draw these up nice and tight.
16:13then we'll fill these holes and we won't have any squeaking later on.
16:16okay.
16:17looks like a bunch of notches were made.
16:18i got my belt.
16:19i can help you make the last what four or five.
16:21yeah we got four or five more to go.
16:23i just squared these down.
16:24what we want to do is square them down from the floor above.
16:27so i just hold my square up against the floor.
16:30line it up with my chalk line.
16:32bring it down.
16:33mark it on each side.
16:34and then we'll do a saw and make a cut.
16:37is this coming out?
16:38yep.
16:39if you get that out it'll be good.
16:40it'll make it easier for us to get the saw in.
16:41get the saw in.
17:11oh tommy you're a beast.
17:16all right now we can get the beam in.
17:18i'll get this cleaned up.
17:20all right we just took the beam off the truck and get it down on the ground.
17:36we gotta flip it over.
17:37it's upside down.
17:38reposition it.
17:39and then slide it in.
17:45all right the beams coming in.
17:47they've got it cabled right here in the center.
17:50so it's doing a balancing act.
17:52they're gonna get it in as far as they can.
17:53and then we're gonna reposition the cable.
17:56all right they're positioning one of the jacks.
17:59they want to carry the load of the end of the beam right here.
18:03you can see the strap that's on the end of the beam that's connected to the lull.
18:07and basically he's holding the end weight.
18:10they're resting the beam right here.
18:12to take the weight off of the cable.
18:14along with the jack down the other end.
18:16we're gonna roll it on the jack.
18:25hey now you're coming.
18:27now you're coming.
18:28now you're coming.
18:29all right you can see they get it in as far as they can go right now.
18:34the cable right.
18:35now they've got to reposition this cable.
18:36they're gonna slide it down.
18:37bring it in a little more.
18:44whoops, watch that side.
18:47this wooden beam.
18:48this is the main beam of the house.
18:49the center beam.
18:50wooden beams.
18:51old wooden beams.
18:52get big cracks in them.
18:53that's called checks.
18:54now as long as they're running with the beam like they are.
18:58believe it or not it doesn't weaken the beam.
19:01so you have a wooden beam.
19:03top and bottom.
19:04it's parallel.
19:05because that's how it comes out of the sawmill.
19:07if you have a check or a crack that runs down the side of the beam.
19:10guess what happens.
19:11if there's no pressure under part of the post or the beam.
19:15it will roll down slightly.
19:17that takes my parallel of 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 of the beam back up.
19:28closing the check of the crack.
19:30making it parallel again.
19:31so the lally column would go in.
19:40oh let it down.
19:45that should be it.
19:48okay.
19:49now we're ready to put the i-beam back into place.
19:52we're going to put it in against here.
19:54get a jack where it goes.
19:56and put the second lally column in over here.
19:58all that load is getting pushed down.
20:00to the footing that's in the basement.
20:07we're putting some temporary bracing underneath the beam.
20:10that way we can reposition the jacks as needed.
20:13make sure everything's safe.
20:17all right we're almost there.
20:18we've got the beam up under the floor joist.
20:20now we have to slide it over.
20:22so it goes in the pocket.
20:24so a little bit of finagling.
20:26a lot of safety watching here.
20:28you don't want anything to break and snap.
20:29you come down.
20:32actually you know what.
20:33have him.
20:34have him go up a little bit.
20:35keep going.
20:36here you go.
20:37go go go go go go.
20:38you got pressure off.
20:39yeah.
20:40good.
20:41all right.
20:42we're past it.
20:43yeah all right.
20:47a little bit of wiggle.
20:48yeah now screw it.
20:53there you go.
20:59all right.
21:00our beam is in the slot that we made all the way across.
21:03now one of the problems that we have to think about here is because the beam's got to go up that much more on the other end and still be about a quarter of an inch below the subfloor.
21:13but.
21:14when we hit here because the house had a little dip in it.
21:18this dip is going to be pushed.
21:20this beam is going to push against the underside of the subfloor tightly.
21:24which means.
21:25when it comes time to put all of the timber hangers on the joist.
21:30we're going to have to jack the joist individually.
21:33making the space above the beam equal along the run.
21:38all right.
21:39he's putting the last nut on the eight bolts.
21:42once he gets it caught.
21:43he's going to use the impact wrench.
21:45tighten them all up.
21:46at the same time.
21:47it may slide the beam in place.
21:48we'll see.
21:53this is a spud wrench.
21:54probably the one tool i don't have.
21:56until today.
21:59he lines the holes.
22:00with this end of 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. what a difference.
22:17so what's next?
22:18well we have about six joists that are really badly damaged.
22:20you have to repair those.
22:21and then install the hangers.
22:23and then we can take the temp walls down.
22:25and even the old exterior wall.
