I had that brush idea in mind for the top of my door, Glad to know it will work before buying one. Perfect video for what I'm dealing with!

[@michaelking42]

Great video, thank you. If I can add a thought, when you are using the expanding foam, if you use 2" painters tape on the surface of the metal siding next to each post, when you cut the excess off it will peal away with the tape.

[@erneststelly4395]

Thanks for your help great information

[@ViolatioNVibratioN]

Dude. This was perfect, especially the bushes on the roll up. Doing all this before I spray foam my shop. THANKS!

[@HIKETOGRAPHER]

Thanks so much for the info! The snow blew in on my doors during the storm this week! Those garage brushes look to be the answer to my problem! Thanks for sharing! One thing to add is if you have any rodent problems, you can add steel wool or a wad of metal window screen ( I prefer this as steel wool can rust and cause stains)to the holes at the corner of the siding to prevent a critter from chewing throw the great stuff. Loved the flags you have hanging in the rafters. Going to add some to mine like that! Looks sharp! Keep up the fantastic work! I really enjoy your videos!

I had a bad result using the spray foam. As Rain blew in behind the corner flashing it would get on the square metal beam and run down till it found a the floor. I ended up having the same issue with the eaves. I removed the 4 corner flashings and filled in / sealed where the two panels met at the corner and then put the flashing back on. Now any rain that gets behind the flashing stays on the exterior and can't get to any of the interior structure. I think it took me 8 tubes of silicone for a 20 * 20 and I was very generous with the silicone.

[@jordanpiesmith]

Thays a good idea, use the foam filler you can buy would probably work great?

[@LegacyCustomTackle]

Great vid! Thank you for taking the time to share with all of us. One curiosity- why not silicone the outside of the building where the siding meets the concrete as well, in order to keep any water from getting between the siding and framing? Thanks again, just subscribed and will be supporting this channel in the future.

[@centexan]

You are correct in that the silicone to prevent water intrusion should go where the water first has a chance of entering. In this case, had he done it outside there would be no need for the second bead inside where the siding and bottom rail meet. The outside took care of that.

[@jamesceja4064]

@@centexan can you do both inside and out? Would silicone the best choice for the outside? Or would Polyurethane work better out side?

[@centexan]

@@jamesceja4064 You can do both inside and out. But if you do a good job outside, the inside is a waste of time and money. Make sure your concrete is cleaned well before caulking no matter what you use. Silicone 2 will last much longer than polyurethane caulk outside. Silicone is uv resistant and polyurethane is not.

[@matthewaldridge6857]

Do they go all over states putting up?

[@caryames7668]

They make a foam rubber closure for that .

[@Waterbottlewithagun]

@PatriotDIY how would i seal where i put a window ac unit in

[@rdblan2]

Those brush seals are awesome. I wish I would have shot a bead of silicone along the floor plate before I insulated and covered the walls. Any info about those shutters you have on yours? Those look great.

[@mawga01]

Great video! Do you have any suggestions for the gaps where the side walls meet the roof? We have a pretty large gap there.

[@jordanpiesmith]

You could use rigid foam board? With the spray foam around it to seal it in place.

[@tommychambers9220]

Hey. Fan of your videos. Wanted to see if you did anything special around your windows. I have the same type of building. The top of my windows touches the horizontal 'rib'. Recently, we had blowing wind/rain and all kinds of water came in. I'm pretty sure it's from around the window. Did you try silicone or some type of flashing around the outside of the windows?

[@PatriotDIY]

I havnt had any issues around my windows so nothing special there.

[@paulmanning4627]

What can u use for water getting in the gaps

[@mccwho]

Get the Pro tool for Great Stuff. The cans go a LOT further. It cleans up very easy and you can easily control the foam flow. Because it is so controllable I was even used the foam around the bottom. Get the tool, it is worth it!

[@OnHoldAt50]

A year and a month since you produced the video. If you don't mind please, how are the brushes on the rolling door holding up? If well, how long do you expect it to last before replacement? Surely weather plays a role in the brush deterioration?

[@michaelking42]

You won't need to replace the brushes, they won't wear out. I don't think the weather would eat them up, neither.

[@theoterrell2010]

Can I use that caulk on the exterior seal against concrete?

[@markm6444]

What did you do about the ridge vent and where the vertical roof siding meets the walls? Wind driven rain will get in those holes, and/or bugs/mice. I have a similar building. Ask me how I know lol.

Great stuff in some spots and My insulation covers it! Everywhere else. Check out my insulation video

Thought I'd share what I did in my metal building. I took the outside door latches off and swapped from left to right and mounted on the inside. . Friends also but on his we had to drill two more holes on each side and plug two old ones with bolt and nut. Know they are only accessable from inside. Ps I like the door brush seals .

[@georgemurray6845]

Just finished mine over the weekend. One other thing with the bottom, I am thinking of pulling the bottom back and inserting a flange to help guide water away from the concrete. Only one problem will be at a location where the concrete comes out from the wall too far. But, thanks, I will consider it. Next thing is insulation choices. A friend recommended the spray foam. Not sure that is the best. Ideas?

[@PatriotDIY]

I had some areas where the siding didn't overlap the concrete properly and I had to add some flashing to the bottom. I have a video on what I used for insulation, check it out. Spray foam is prolly best but it's expensive

[@georgemurray6845]

@@PatriotDIY AH! Thanks, I have to get the guy to price it out. May be out of my budget with a 30 by 50 by 14 then. I used to work for a resin company years ago and had the foam available to use. Could have done the job myself because I sold the equipment. But, it was carcinogenic and dangerous to work with.

[@lisaray9404]

Thank you for the video! This helps me with my big metal garage and my little metal handi-house. One question: how do I keep water from intruding the roll-up door on my garage.

Did u foam the top of the roof where the roof cap is, on my steel building u can see where the light is coming through, just curious how or if u sealed that gap on your building, great video by the way has helped alot

[@PatriotDIY]

No but it is covered by my insulation. I have a video on that too

[@kalnory146]

mine has birds coming in.. 🤬

[@KB3M]

I have a very similar building with 3" of concrete extending beyond the panels. I see you chalked just the inside but I'd be concerned that water would come in from the outside and sit under the square tubing and take forever to dry with the inside sealed. I do like the idea of adding fasteners to tighten up the horizontal panels but I would definitely also seal it with Loctite Concrete sealant to keep the underside of the perimeter tubing dry. Once I see no water coming in, then I'd seal the inside.

[@PatriotDIY]

My concrete has a 3/4" step down from the inside surface to the outside surface and my siding overlaps that. This prevents water from seeping in, I just added the scylicone as an extra measure and to keep bugs out

[@ralphmowery2898]

I started to do that but the contractor told me it would be better if the siding would extend over the concrete so the water would not run under the walls. Did that and no water problem. Also where the doors are I had them to give it a slight slope so the garage was about 3 inches higher than the drive way.

[@yamlcase230]

what size building is this?

[@kevinsnyder333]

Did you paint those brush seals black? All the ones I see are bare metal and I need black for my black trim. That black looks great.

@@PatriotDIY thanks!

[@mdub2943]

Great video thank you. 1 question, when siliconing the base rail to keep water out would it make more sense to do this from the outside instead so that water doesn't get under the rail and stay there? Or am I overthinking it?

[@PatriotDIY]

Both would be great! The best thing is to have a 1in step down lip around your slab and have the siding overlap it so water cant settle at the bottom of the wall. That's how mine is, so water isn't much of an issue for me, I mainly sealed mine to keep out dust and bugs!!

[@mdub2943]

@@PatriotDIY copy that thank you. I did that on 3 sides but on the 4th I extended out for a walkway and that was a mistake because water comes in. Thinking about shoving a silicone backing seal under the base rail then siliconing inside and out. Thanks again!

Did they install flashing on the outside of your shop? To keep the water from coming in between the concrete and metal frame. If not, how has the caulk worked for you on the outside to prevent any water from coming in?

[@PatriotDIY]

My slab has a 3/4" "stepdown where the siding meets the concrete, so the siding actually sits below the main surface of the slab. No water issues and no need for additional flashing.

yep i did the same thing putting silicone down it does not work water is still coming through

[@PatriotDIY]

Sounds like your problem Is your siding resting on the top flat of your concrete allowing water to settle and get under the wall. Your siding should overlap the concrete. You will likely need additional flashing on the exterior.

[@repentanceMeans2TurnAwayFrom]

What kind of window trim is that?

[@gg-gn3re]

Quad is "elastomeric polymers and high quality synthetic resins" not silicone based. More of polyurethane

[@DD20248]

I tried this quad stuff and bought about 7 tubes of this stuff at lowes,they are more expensive than regular sealants.I bought the white stuff and used it all around the perimeter of the building,sealed top and bottom.This stuff does not work!A rainstorm occurred here in Pensacola and in the morning the floor of my 2 car garage was flooded with water!

[@PatriotDIY]

Well you need to make sure you use enough and get a good seal , it also requires that you have proper grading around your shop and you have the siding overlap the slab like it's supposed to..... This stuff works but it doesn't perform miracles...sounds like you have way bigger problems than sylicone...if you have bad drainage and poor grading or your siding is sitting on top of the concrete without an overlap you need to fix that first !!!!

From my experience spray foam is terrible! It's toxic when it burns and it's just a millionaire holes that cause it to leak? Why would they have a building where you can actually see the light through the corners of the walls? It seems like there's very little care done with engineering and designing?

[@bruceradz]

They should have the option for the owner to have a prefabbed rubber composite seal to be installed on all the corners between the metal posts and the metal siding. In this day and age, why isn't this even an option for the owner at construction time

[@maxpower9848]

Now I'm officially confused? I just watch a video where they cut two inches off each side of the roof to make a giant hole and now the next video is patching the holes with foam sealant? Isn't that going to cause a massive condensation problem?
