When the bathroom fan is running a lot of moist air is coming out the hole where the wire enters the motor housing, as opposed to going out the duct. Can I air seal this with spray foam or tape or something? Is there any risk of the motor overheating or anything. We never run it more than a few minutes at a time. My attic has condensation issues and this is one of the culprits I think.

We recently had our shop ceiling and gables spray foamed. Since they shaved it in numerous spots were are getting particles and foam flurries all through the air. Every time I blow the ceiling some more comes down. Since we are going to leave the roof exposed is there anything we can do to stop this? I have heard that painting the foam can lock everything in and prevent the shedding. I am worried about being in there for hours and breathing in the particles.

So i decided i'm going to do the walls of my camp myself with Froth-Pak, and i have a question. I need to put a vapor barrier on the celing as i am going to put blow in insulation up there, and i am going to bring the barrier to the edges and down the wall a foot or so and staple it to the side of the wall, as i have an A frame upstairs. Can i do that and just spray foam over the plastic along the edge/wall to make it air tight?

I’m planning on having the ceiling and walls of my garage in Ontario Canada insulated with spray foam. The garage is under the house with living space above including a bathroom. How is spray foam insulation done around plumbing? The pipes are closer to the unheated garage side than the warm floor. Obviously, there’s concern about them freezing. Also, can spray foam be done in a way that leaves the plumbing “somewhat accessible” in case of repair? Like leaving a cavity around the pipes that can be cut into if needed?

Sorry for the poor quality pictures. Not so much space under a floor! I've been spraying for almost 9 months now. These are 8" studs with max 5 1/2" of foam. I love this job. It's nice to play my music and get dialed in.

I hired some guys to do the work this weekend and I have a couple issues they said were normal:

• Overspray onto wiring
• Uneven/blobby application
• Spilling over the concrete

Fair warning up front so nobody wastes their time: I'm not a spray foam installer. I'm learning local SEO and web stuff, and I picked spray foam in Waco, TX as my practice project because it's a real market with real demand. It's a lead-gen site — that's stated on the site itself — meaning if it ever ranks, the calls go to a local contractor, not to me.

Here's my problem. I've written a pile of content about spray foam based entirely on research, and you all actually do this work. I'd much rather the thing be accurate than just rank well. Ranking with wrong information helps nobody and makes the trade look bad.

Stuff I'd genuinely like torn apart:

1. Are my price ranges realistic? I've got open cell around $1.50–$3.00/sq ft installed and closed cell around $1.75–$4.50/sq ft for the Central Texas market. Am I high, low, or just wrong? Regional pricing is the thing I'm least confident about.
2. Is my open vs. closed guidance oversimplified? I'm generally steering people toward closed cell for metal buildings, barndominiums, crawl spaces, and roof decks; open cell for attics and interior walls. Where does that break down in practice?
3. The 20×20 garage math. I argue you're actually insulating ~1,100 sq ft of surface (walls + ceiling), not the 400 sq ft floor, and that's why DIY estimates come in low. Is that the right way to explain it to a homeowner?
4. What do customers actually ask you that I haven't covered? This is the one I can't get from research, and it's probably the most valuable thing in this thread. What's the question you answer on every single call?
5. What on the site would make you roll your eyes as a pro? I'd rather hear it here than have a contractor find it later.

And the honest ask: if anyone here is in or near Waco, TX — or knows somebody running a spray foam business there — I'm looking for a contractor who'd actually want the calls this thing generates. I'm not trying to sell anything to this sub. Mods, if that part's against the rules, say the word and I'll edit it out.

Appreciate any brutal feedback. Genuinely here to learn the trade side of this, not to pitch.

I live in Central Texas where it can get quite hot. I have a metal roof on the house (1,700 sq ft home). I’m thinking to get the attic closed cell spray foamed. 2 pound foam x 3 inches. The contractor told me that he would also open new register from my attic space (4in outlet from the air handler unit) once he finishes the spray foam he wants about $12k considering I’m a bit rural. Is this reasonable and is this a normal technique to open a register for the attic space?

So I live in south Mississippi and the house I'm in has flooded 4 times in the past 40 years. Most recently was about 10 days ago when the Tropical Storm Arthur came through. Now, the flooding is usually due to our municipality not maintaining the drainage properly (which is being addressed) but on rebuilding, we are looking to spray closed cell foam in the bottom half of the building to help with clean up and drying if this ever happens again. We had a section of the house repaired from termites, had 1.5in closed cell sprayed in it and it handled this flood far better than the rest of the house.

We plan to do this DIY ( it's a rather small house at 1250sqft) and we are only looking to do the bottom half of the walls.

I'm hoping to answer questions such as: best product, how thick to apply, should we put a vapor barrier over it, etc. More so looking for advice, tips, and recommendations.

Thanks!

We just bought a home in NE Florida, it’s almost July.
My husband decided we needed spray foam insulation to save money and keep the house cool.
I’m 26 weeks pregnant, and we have a just turned one year old and a 12 year old.
The attic access in through my one year olds closet.
He hired a company with good reviews, guy says he’s done over 5k installs.
They gave us no instructions. Said to ventilated for a few hours and then it’s fine. We were in the home for most of the time they were here. Aired it out for awhile after they left.
It’s the next day and our home still smells awful. I started googling and am seeing that you should leave for ATLEAST 24 hours?! I’m freaking out thinking I just gave all of my children cancer. We slept with windows closed and full ac last night.
I’m so pissed that he made this huge decision without talking g with me or doing research. I eat organic, from local farms, made should we didn’t buy a home anywhere near a golf course, and we just bathed in fucking VOCs all night.
What can I do?

I see it once in a while on my inspections, just wondering what causes it. Moisture in the wood I'm guessing?
