Is Your Door Leaking Cold Air? How To Insulate A Door | GardenFork

– What’s exciting? What is exciting here? Ready? Okay, tennis balls. Check. Take your ball; do you want the ball? Henry, you want the ball? Charlie? Get the ball. Go! I’ll be right there. (dogs barking) So, this door leaks really badly cold air. Well, hot air too I guess in the summer, I just realized that. But I was gonna fix it and I thought, why don’t I make a video about… (dogs barking) barking dogs. Come on in, come. Henry, come. I thought why don’t I make a
video about how to fix this because it’s an old
building with an old door and maybe you’ll learn something, or at the very least you
get to have your camera whacked by a Labrador tail. All right, today on GardenFork. Ready? Here we go. Go on, out. (dogs barking) They forgot the ball again. Go! Make, fix, grow, cook. GardenFork. Our challenge today: fix as
much of the leaks as we can without dumping a ton of money. Ideally, what we should do
here is replace this door because it’s actually an interior door set as an exterior door. It’s not double glazed, it’s
not insulated, yada, yada. But, we don’t have the cash for that, so let’s walk through a couple
of things we’re gonna try and see what happens. I was just running my
hand along the door frame right here and I could feel cold air coming in. Little bit of cold air here too as well. Let me show you what I found. When you pull this off, you
can gently pull these off. I’ll show you the tool I use for this, but you’ve got that. That, cosmetically you don’t see it because it’s covered with this, but thermatically, is that the word? Cold-wise, that’s all cold air coming in there ’cause this is basically a straight shot. There’s another piece of trim
on the outside of the door, but there’s cold air coming in here, so I’m gonna show you
how to fix that, okay? Let’s go outside. First of all, this (knocking) is hollow. It’s not flush up against the brick and I don’t expect it to be. There’s cold air coming in here,
going behind the pine trim, behind the trim in the
inside, and into the house. It’s easier to take the indoor
trim off than the outdoor. Ideally, we would take this off as well, but it’s about 20 degrees and the temperature is gonna drop today. Yeah, I can see some big cracks here, but we’re going to work
on the inside today ’cause it’s a little warmer and it’s easy. There you go. Come on, I got work to
do, we gotta go outside. I can’t play right now. I can redo this gasket here. I’ve already put new foaming material here and that helps when the door closes. I also put a sweep here. This is quite a gap here at the top. This is just the top piece, I haven’t even taken off the sides yet. If you put your hand here, wow cold air. Come on. Nothing is ever straightforward
in a 110-year-old house, so I wanna get this piece of trim here, which is wrapping around this wood column, because it’s a load-bearing
wall that they removed, long story. But, I need to get this piece
of trim out and it’s nailed and the hinges are keeping
it from me getting it out, so I have to be a little creative, but I have favorite tool
for this kind of thing. This is really good for prying off trim. It has a really… Is that narrow, what’s that? Like crowbars kind of have a blunt end, this goes really in nicely. I’m gonna try to pry this out. If not, I have a little mini hacksaw I can cut the nailheads
off and pull this off, but that’ll take a while, so here we go. This is gonna go in. The nailhead is right
here, which is a challenge. I’ve got that to go out, but I’m hitting the hinge here. So if I’ve got this out, let me show you a little trick I do. This is a nice tool. Mini hacksaw, don’t cheap out. I’ll list this tool and a
bunch of the others I’m using in the show notes below. But this, I’m going to cut that. It’s kinda hard holding
a camera and doing this. I’m gonna put this behind here, here and cut the nail off on the back end, this will allow this to come off. They sell cheap versions of
this and they will break. This thing has saved me on a lot of jobs. In an old building, you
need to get this thing off. It’s not an expensive
tool, but it’s worth it. Here we go. (sawing) Nice. So that all the way through now. There we go. Looking at this side, it’s not too bad. I’m just gonna use caulk in there. It’s a fairly small gap and a high quality caulk
will work really well. Going up this, it’s a big gap, caulk
is not gonna work there. It’ll fall in on itself basically, so we’re gonna use one of my
favorite tools: spray foam. Okay, a couple rules
with using spray foam. I love spray foam. I’m big on insulation, if you can’t tell. A couple things here. First of all, cover up anything that you don’t want spray foam on. When you’re spray foaming,
that’s my visual for foaming, it’s gonna drop to your floor, so put this down so you
floor doesn’t get foam on it. Two, masking tape. Tape off what you don’t
want spray foam to get on ’cause it’s just gonna fill
and then a little later it’s gonna go boom and
kinda grow a little bit, so this makes it easier
to get that growth off. This is a must and clothing
that you don’t care about because you’re gonna get spray
foam on you or your clothes. You don’t wanna get it on your
arms ’cause when it dries, it really hurts to get off. So, clothing you don’t care about, or work clothing basically,
gloves, eye protection. We’re good to go. Shake this up really well. A little bit of spray foam goes a long way ’cause it’s going to expand. The door and sash or
window and door spray foam is a minimally expanding spray foam. The idea is it’s not
gonna warp the door frame so the door won’t close, but it still does expand,
so keep that in mind. A little bit goes a long way. Here we go. I try and shoot it in the crack there and I move this along. You’ll just kind of get a feel for it and there’ll be kind of a
zen flow to your spray foam. You can go back in and seal
any gaps that you noticed. I don’t know, I just get
excited about spray foam, it’s one of those things. But, let’s watch this dry. You can kinda see it’s
already blowing out, which is a good thing. It’s foaming out I guess is the word. This is a reusable brand, so if you clean out the straw tube and the little applicator, this white part here, I don’t know what that’s
called, the trigger. I use a coat hanger and
I run it through water. It doesn’t do a great job, but you can still use
what’s left in the can for another project, but fairly soon ’cause
this stuff hardens up. This, we’re just gonna let
this dry and this’ll actually puff out a little bit more
and then we’ll cut it off. Get the most expensive caulk you can find. Don’t cheap out on your caulk because you only wanna
do this once, right? This is a quality, all-purpose,
outdoor, waterproof caulk. This has an odor to it, so you might wanna wear
an organic vapor mask or have the windows open. But, it’s freezing cold and
I’m not doing a lot of it, so I’m just gonna run this bead and then we’ll be outta here. (soft music) (dog barks) – [Woman] Hi. – Who’s this? Who’s this? Is it nice out there? Remember this? I barely sprayed it in there, but just to show you how much it can grow. Boom, it pushes out and I
like to let it dry overnight ’cause this, you can break this off, but I think you’re better
off taking a long blade, like a utility knife
blade or a hacksaw blade, and just slicing it down ’cause if you break
this off on the inside, you’re pulling out some of the insulation. Don’t eat this, throw it out, okay? This is my tool bucket on wheels. I made a video about this a
while ago, maybe I’ll update it, but I’ve got some
favorite tools that I use. I don’t buy a lot of fancy tools, I buy tools that are good and last. But if you want to, I’ll
link to that video below. Then you have to click
below to watch the link, or there’ll be a link at
the end of the show there. But in case you’re curious
about tools to have, I have some thoughts on that. Ear protection, eye
protection, brad nailer, put this all back together. There’s no breeze here, isn’t that nice? (woman laughs) Big difference, really
big difference isn’t it? – [Woman] Yeah, it’s really good. – We noticed last night that there wasn’t this blast
of cold air coming through, so that’s pretty cool. If you wanna learn more
about me and my world, there should be some videos floating here and also if you click the down button, there’ll be a bunch of
text below the video and you just kind of learn
about Eric and stuff, I guess. (woman laughs) I always want to hear from
you, so comments below right, I learn from you ’cause
I’m not the expert. All right, make it a great day. – [Woman] You gotta go shovel. – Yeah, see ya. (woman laughs)

Nice job. I live in a old house too and it took weeks to get rid of the drafts.

Now that you've sealed that up all the other air leaks will present themselves a bit stronger. When I replaced our front door the bedroom became significantly more drafty.

How do you insulate a door? Let me know here!

Is there a way to repair a double insulated replacement window? We have foggy replacement windows. Something short of replacing the replacement window? Windows are drafty too. Thanks.

If you know you may be using your foam several times you can cut the straw down and get a plastic drinking straw of the same size. This way the part you need to clean will be smaller and easier to manage

Thanks. I’ve got an annoying PVC door in my workshop that leaks air faster then an industrial fan. This video prompted me to get off my ass and do something about it….tomorrow.

For sure pulling the trim and sealing things up helps a lot. Not so much as a door leak as it is air infiltration/exflitration.
My personal favorite door insulator for doors that are really "bent" or frame twisted, is the screw down fabric covered foam aluminum door seal kit. There easy to find, just look for the most expensive one.
Great filler when your up against a rock & a hard place when trying to fill a crack in any weather… IS them disposable bags from the store, you want paper or plastic? yeah, them kind
WOOF guys… go get the ball

It doesn't make any sense to fix an old door like that. You are losing almost as much through the glass panes, and it's not even an exterior. Even if it was, the old exterior doors are pretty worthless. You need two layers and insulation in between. You might have to look around to find a door that fits with an older house like that, but I'm sure there are some around. Myself, I would buy a cheap, no glass insulated door at Menard's and paint it to kind of match. Heat loss is way too important to play around with.
After that I would add an inch of high density foam to every exterior wall from the inside.

Can you re-apply to completely fill the gaps in the next day?


Feb 2, 2018, 2:07 am Reply

Could be where we're currently living. The building is 118 years old. Drafty as all hell. But the worst is the kitchen, that was fixed by sealing the gap at the bottom of the door.

Which is precisely why they call it a drop cloth.

Great post Eric. Lol spray foam is great but can be a mess (when I use it anyway)
I have ruined countless shirts & favorite worn out jeans due to wonderful spray foam.
Indeed as duly noted. it is extremely difficult to pull from arm hairs.

Nice. I like the way the old door looks (even if it’s an interior door) unless you spend a ton of money you won’t find a new replacement that has the same character. Just a tip a modified urethane sealant like tremco works great for sealing the exterior trim work it remains flexible and the adhesive properties are awesome. It’s all we used back when I did industrial metal roofing and siding. Did allot of work on 100+ year old factories where you had to seal between a brick surface and flashings

Good video as always thanks! I too love spray foam but, like you said, cover everything you don't want foam on… including yourself! My tip is modify the straw! I just heat it with a heat gun or lighter then just smash it so the last couple inches are skinny and will fit much deeper into any crack or crevice!

That's one of the cutest Labrador dogs I've ever seen in my life. Ben was my partner in crime when I was a kid, big Labrador, we had some legendary adventures… but he died. I think I'm going to have to get another one, after I spray foam my annoying door.
