Room over the garage won't cool down? Closed-cell foam seals air leaks and insulates in one dense layer, where it's worth the cost.
Closed-cell foam insulation is a dense spray foam we install in Laredo homes to stop heat, air leaks and moisture vapor in one layer. It costs more than open-cell foam for the same space, so it pays off in certain spots and not everywhere.
Most calls start with a room that won't stay comfortable, usually the room over the garage or a hot upstairs, and the first question is whether foam is the fix. The price moves with how much area we're covering, how thick the foam goes, how easy the space is to reach and whether old material needs insulation removal first. The schedule depends on that same prep, plus getting everyone out of the house while we spray. I write all of it into your estimate so you can see what's included. We're based in Laredo, TX, and we work in Laredo and the cities around it.
I come out myself to look at your attic or problem room, and I'm the one who writes the estimate. On install day I'm up there with our small crew, so the person who made the plan is the person checking that the foam went where it should.
I traded a desk job for this work and learned insulation on another contractor's crew before we opened in 2023. Three years in, attics are what we're best known for, and the desk still hasn't called asking for me back.
We're licensed and fully insured. Our work is backed by our satisfaction guarantee. If you want to talk through your space, call (956) 508-9070 or use the form on this page, and we'll set a time for me to come take a look.
Tell us the area you want insulated and whether your attic has vents, and we'll reply within one business day to set up a free on-site estimate, with no obligation. I'll come look at the space and write the estimate out so you can see exactly what's included.
The City of Laredo uses building permits to check that work is safe and meets code, and the city decides whether a given job needs one. If you're not sure about yours, Building Development Services answers permit questions at 956-794-1625. When a job needs a city permit, we pull it as your contractor and handle the paperwork with Building Development Services. You can pull it yourself, but the city then considers you the contractor for the project.
Around Laredo, most of our calls are rooms that won't stay comfortable, often a room over the garage or an upstairs bedroom, plus a few shops and offices. A lot of houses have ductwork running through the attic, and that's where closed cell earns a serious look. We do the same work in the cities around Laredo, and our Laredo insulation contractor page covers the rest of what we do here.
There's no set price, because it depends on the area covered, how thick the foam goes, how easy the space is to reach and what prep it needs. Closed cell costs more than open cell for the same area because it expands less, so it takes more material to fill the same space. I'll put your number in writing after I see the space.
Closed-cell foam is rigid and hard to compress, with an R-value, the measure of how well insulation slows heat, of 6 per inch. At its usual thickness it also blocks moisture vapor almost entirely. Open cell is softer and lighter and doesn't do that moisture job, which is part of why it costs less.
Everyone in the house should be out while the foam goes in, and some makers of professional spray foam recommend 24 hours before you come back, though it can vary. We follow the re-entry time, the point when it's safe to come back in, that the maker sets for the foam on your job. Other workers on the house should be out during spraying too, so plan other projects and a place for the kids and pets around it.
A sealed attic makes the most sense when your ductwork is up there, and it's worth thinking about moisture first. One building science guide says spraying open-cell or closed-cell foam right under the roof deck can bring the attic inside the cooled part of the house, with closed cell as the denser option. Past research also suggests that in hot, humid climates a sealed attic could leave a home more humid and less comfortable than a vented one, so I look at how your house handles moisture before recommending it.
You can, but read the product information carefully first. Safety guidance for spray foam says people with a history of skin conditions, respiratory allergies or asthma should do that and may want to consider another insulation. If anyone at home has asthma or skin trouble, I go over the product info with you before you decide.
No. A spray foam trade group says the foam doesn't attract termites or feed them. Termites can still travel through it, though, so whoever inspects for termites needs to be able to get a look, and we keep that in mind when we plan where the foam goes.
