Cold rooms, a drafty upstairs or a power bill that doesn't add up? We find the hidden gaps and seal them first.
Air sealing services in West Lafayette close the gaps around doors, windows, pipes and the attic floor that let your heated air leak out, so rooms stop feeling drafty and the insulation you already have can do its job.
Most calls start the same way. A bedroom won't warm up, the upstairs is hot all summer, or the power bill doesn't make sense for the size of the house. Usually the air is moving through gaps you can't see, under the insulation already in the attic, so piling more attic insulation on top doesn't fix it. The price moves with how much old insulation sits over those gaps, how many openings there are to seal and how easy your attic is to get into. The schedule turns on that same access, plus anything we find when we check your gas appliances. Your own figure comes from the estimate, once I've seen the attic.
I'm the one who comes out, climbs into your attic and gives you the estimate. I also work alongside our crew on the install, so the person who pointed the flashlight at your gaps is there making sure every one of them gets sealed.
I left an office job, learned insulation on another contractor's crew and started this business in 2023. Three years in, we're best known for attics and air sealing, the unglamorous work that decides whether new insulation actually pays off.
I'd rather tell you a job isn't worth doing than sell it to you. We're fully licensed and insured. Satisfaction guaranteed on every job. Call (765) 250-8264 or send the form, and I'll come take a look.
Call (765) 250-8264, send the form or email contact@westlafayettesprayfoaminsulation.com, and we'll reply within one business day to set up a free estimate at your house, with no obligation. I come out myself, look over the attic and your appliances, and walk you through what I'd do and what it costs. It helps to know how you get into the attic and which appliances burn gas or other fuel.
In West Lafayette, the city's Building Department issues permits for new construction, structural changes and electrical work, and air sealing isn't on that list, so the list doesn't settle whether your job needs one. The Building Department is the place to ask. We check which office covers your address, since city limits change who you deal with, and we handle the permit side with that office when your job calls for one.
Most of what we see here is older houses with drafty upstairs rooms, several layers of old insulation in the attic and a room over the garage that never warms up. We're based in West Lafayette and do the same work in the cities around it, including Lafayette, Crawfordsville, Frankfort and Monticello. If cost is what's holding you back, Indiana's Weatherization Assistance Program can serve households with incomes up to 200% of the federal poverty level, along with households eligible for the Energy Assistance Program whose homes are safe to weatherize. Its work can include attic and wall insulation and sealing drafty areas around doors and windows, and after the program's audit, state-trained contractors install what the auditor prescribes at no cost to you.
The price depends on your attic, so I give it after I've seen the house. Old insulation that has to be moved or pulled out to reach the gaps adds the most, along with a long list of openings like can lights and plumbing runs. Sealing and topping up loose fill usually comes in lower than foam, and doing the sealing and insulating in one visit saves a second trip.
You can handle the easy gaps, like weatherstripping a door, but attic leaks are usually too small and too buried to find on your own. National air sealing guidance says a do-it-yourself approach won't work for those small, hard-to-spot leaks, especially in attics of existing homes covered by layers of insulation. Energy auditors find them with a blower door test, a fan in a doorway that pulls air out so leaks show up, and an infrared camera that shows where air is getting in.
Book the air sealing first and the insulation right after. National attic air sealing guidance puts sealing ahead of insulating to get the most energy savings, since insulation laid over open gaps just ends up fighting a draft. ENERGY STAR estimates, reported by Purdue Extension, put the savings from sealing and insulating together at up to 20% on heating and cooling costs, so it's worth planning the two as one project.
Yes, when the crew checks your furnace and water heater as part of the job. Indiana's weatherization field guide, which is guidance for the state program rather than building code, tells its crews to always evaluate ventilation and run combustion safety testing, a check that fuel-burning appliances still vent their exhaust properly, as part of air sealing. When you're comparing crews, ask whether they test for air leakage before they start, since that guide directs it too.
Start in the attic. The same state field guide says sealing attics and roofs may be the most important and cost-effective weatherization step, and the attic is a common spot for both air leakage and moisture damage. If your upstairs runs hot in summer and cold in winter, that's usually where the air is going.
