Spray foam insulation in Lafayette IN - the right foam for each part of your house
Cold floors, a drafty room over the garage or a hot upstairs usually trace back to air leaks. We find them and foam them shut.
Is spray foam the right insulation for my house?
Spray foam insulation in Lafayette, IN is a liquid we spray onto rim joists, attic gaps and open walls, where it expands, seals the air leaks and insulates in one step, so a draft and a cold spot get fixed together.
Most calls I get start with a drafty room, cold floors or a hot room over the garage, and foam isn't always the answer. It costs more than other insulation, so on an open attic floor I'll usually tell you that sealing the attic's air leaks and topping up what's already there does the job for less, unless your ductwork runs through the attic. The price moves with how much area we spray, which foam each spot needs and what has to be fixed or pulled out first, and the schedule turns on that prep and on when your household can be away while the foam cures. When I come out, I walk through the space with you and write out what I'd do and why, so you see the plan for your own house.
How we do spray foam insulation
I start by looking for anything that shouldn't get buried, like a roof leak, old insulation that got wet or is full of droppings, or open gaps around can lights, pipes and the attic hatch. If the roof leaks, I'll tell you to get that fixed first, because foam over a wet spot just hides the problem. Then I go over which foam fits each part of the house, walls below ground included, and we set the day around when your household and any other trades need to be out for the product we're using. On spray day our crew covers what needs covering, keeps the eave vents clear on a vented attic so it can still breathe, sprays to an even depth all the way out to the edges and cleans up, and when they're done I check the work over with you.
Foam is usually one piece of a bigger job. On an open attic floor, we often foam the gaps and then blow loose fill through a hose over the top, which is the blown-in insulation side of our attic insulation work, so you get the seal where the leaks are and the depth for less money.
Open-cell foam
Open-cell is the softer, lighter foam, and it suits above-ground walls and rooflines where you want the air stopped without paying for density you don't need. It usually costs less per inch, so it stretches a budget over a bigger area.
Closed-cell foam
Closed-cell is the dense foam that blocks moisture as well as air, so it's what I reach for on rim joists, crawl space walls and anything below ground. It costs more, which is why I use it where moisture is the problem and not everywhere.
Spray foam insulation permits and houses in Lafayette
Inside Lafayette city limits, building permits come from the City Engineer's Office, and the city requires one for new construction and for any alterations, repairs or changes to an existing building. Outside Lafayette and West Lafayette, most of the county applies with the Tippecanoe County Building Commission instead. Before we schedule, I look up which office covers your address, and if your job needs a permit, we handle the paperwork and tell you what the office needs from you. On a city home, that includes your signature on the city's residential permit application or your written authorization, even with us handling the rest.
We're based in Lafayette and work across the cities around it. A lot of the houses we see are older, with leaky rim joists, rooms over the garage that fight a draft and old insulation that has settled or gotten wet, and we find the same on jobs in West Lafayette and Frankfort.

Why call us for spray foam
I write every estimate myself
I come out, go through the attic, basement or crawl space with you and look for anything that should be fixed before foam covers it. Our install crew does the work, and I check it over with you at the end.
Years of commercial spraying first
I sprayed foam and blew fill on warehouses, offices and new buildings for years at a big commercial outfit before starting this business in 2017. That background is why I can tell you where foam earns its cost and where loose fill does the job.

Spray foam questions from Lafayette homeowners
How much does spray foam insulation cost in Lafayette, Indiana?
Spray foam insulation in Lafayette usually costs about $2 to $5 per square foot. That's the going rate in the area, not our quote, and where your job lands depends on the foam type, how thick it goes on and how much prep comes first. I write out the plan for your house at the estimate.
What is the best way to choose between open-cell and closed-cell spray foam?
Choose by how much moisture the spot sees. Open-cell foam stops air very well but lets water vapor through, while closed-cell foam at 2 inches or more blocks it. An older federal building guide adds that in cold climates, closed-cell at that thickness means you don't need a separate vapor retarder, a moisture-blocking layer.
Can open-cell spray foam go on basement walls below ground?
Usually not. Open-cell foam lets moisture through, and one federal building guide rates it not acceptable below ground level for that reason. For basement and crawl space walls that sit below ground, I leave open-cell off the list and plan for closed-cell.
How long do we have to stay out of the house after spray foam?
You stay out while we spray and until the foam has cured and the house has been aired out and thoroughly cleaned. Some makers of professional two-part foam recommend 24 hours before residents return, but the wait varies by product. I tell you the wait for the foam we're using when we set the date, so you can plan for kids and pets.
What causes cold floors and drafts along basement or crawl space walls?
It's often the rim joist, the wood band that sits on top of the foundation wall, where outside air slips in through small gaps. Spray foam can seal and insulate that band in one step, which takes care of the draft and the cold at the same spot. It's one of the first places I look on an older house.
How do I get my house ready for a spray foam insulation job?
Plan time away for everyone in the house, and keep other trades off that day too, since workers who aren't spraying should leave as well. Move stored things out of the attic or basement so our crew can reach the framing, and get any roof or plumbing leak fixed first so the foam doesn't seal it in.
