Hidden gaps in your attic, walls, and basement let cold Indiana air in and conditioned air out. We find and close those gaps so your home stays warm without your furnace working overtime.
Air sealing services in West Lafayette close the small gaps, cracks, and openings where outside air enters and conditioned air escapes - most jobs are completed in a single day with work focused in the attic, basement, and crawl space rather than your living areas.
Most air leaks are invisible and hidden in places homeowners rarely look - behind electrical outlets on exterior walls, around pipes and wiring where they pass through the attic floor, and along the rim joist where your home meets its foundation. In West Lafayette, where homes near Purdue University were often built in the 1940s through 1970s without any air sealing strategy, the leakage can be dramatic. Many homeowners who schedule air sealing also pair it with basement insulation since the two improvements target the same heat-loss pathways in older homes.
The ENERGY STAR program estimates that sealing and insulating can cut energy costs by up to 15 percent. In a West Lafayette home running gas heat from October through April, that adds up to real savings month after month.
If one or two rooms in your home feel noticeably colder than the rest during a West Lafayette winter - even with the heat running - cold outside air is getting in somewhere nearby. Common entry points are gaps around windows, outlets on exterior walls, and attic hatches that do not seal tightly. You can often feel a faint draft near outlets or window trim on a cold day.
If your heating bill spikes sharply in November and stays high through March, your home may be working much harder than it should to stay warm. West Lafayette winters typically run five to six months of meaningful heating demand, so even moderate air leakage adds up to real money over a season. Comparing your bill to neighbors with similar-sized homes can give you a rough sense of whether yours is unusually high.
If surfaces in your home get dusty again very quickly after you clean them, air may be moving through from dusty spaces like your attic or crawl space. That air carries fine particles with it. This is especially common in older West Lafayette homes where the attic floor has gaps around light fixtures, plumbing, or the tops of interior walls.
If you have seen ridges of ice build up along the edge of your roof after a snowfall, heat is escaping through your attic and melting snow unevenly. The meltwater refreezes at the cold eaves, forming a dam that can back up under shingles. This is a well-known problem in Indiana winters, and sealing the attic floor is one of the most effective ways to prevent it from recurring.
We begin every air sealing job with a diagnostic assessment - and for thorough work, that means a blower door test. This is a large calibrated fan that fits into your front door and measures exactly how much air your home is losing. The test takes about an hour and gives us a real picture of how leaky your home is and where the biggest problems are, rather than guessing based on visual inspection alone. Once we know where the air is moving, we seal gaps using spray foam, caulk, and weatherstripping appropriate for each location.
Most of the work happens in spaces you rarely visit - the attic floor, the rim joist in the basement, and penetrations around plumbing and wiring. Your living areas are not significantly disrupted. We run the blower door test again after the work is done so you have a before-and-after number showing the actual improvement. We also assess whether your home needs additional attic air sealing as a standalone follow-up if the attic floor needs more focused attention.
Best for older homes that have never had energy work done and want the most complete improvement in one visit.
Ideal for homes with high heating bills and ice dam history, targeting the biggest single source of heat loss.
Suited to homes with cold basements or crawl spaces where the foundation edge has never been addressed.
For homeowners who want a documented before-and-after measurement of air leakage, with or without immediate remediation.
West Lafayette sits in a climate zone where winter temperatures regularly drop to single digits and wind chill pushes well below zero. When your home has gaps, you feel it fast - drafty rooms, cold floors, and a furnace that runs almost constantly. This is the most common reason homeowners here call for air sealing. The payback on the investment also tends to be faster in Indiana than in milder climates because heating demand is real and sustained from October through April. For homes near Purdue University built in the 1940s through 1970s, the leakage has often never been addressed in the lifetime of the building.
We serve West Lafayette and the surrounding region including Kokomo. West Lafayette also experiences humid summers followed by dry, cold winters - a pattern that pushes moisture into walls and attics through the same gaps that let air move. Sealing those gaps does more than improve comfort - it protects your home's structure from the kind of slow moisture damage that only shows up years later when it is expensive to fix.
We respond within 1 business day. We will ask about your home's age, what you have been noticing, and whether you have had any energy work done before - so we come prepared and give you a realistic picture of what to expect.
We walk through your home, identify likely problem areas, and run a blower door test to measure exactly how leaky your home is. This takes about an hour and gives us a real number to work from, not just a guess.
After the assessment, you receive a written estimate that breaks down what will be sealed and the cost. This is the right time to ask questions - including whether utility rebates from Duke Energy Indiana or AES Indiana apply to your project.
The crew seals gaps with foam, caulk, and weatherstripping in a typical one-day visit. We run the blower door test again at the end so you have a before-and-after number showing the actual improvement - not just a promise.
We respond within 1 business day. There is no obligation - just an honest conversation and a free estimate. Someone from our team will call to schedule your home assessment.
(765) 637-0109We test your home with a blower door before the work begins and again after it is done. You receive a written result showing the actual reduction in air leakage - not just a contractor's word that things improved. Most homeowners appreciate having a real number to point to.
A significant share of West Lafayette's housing stock was built in the 1940s through 1970s with no energy sealing strategy. We know what to look for in homes of that era - where the gaps typically are, what materials work best, and how to get the most improvement from a single visit.
Duke Energy Indiana and AES Indiana both serve the West Lafayette area and offer rebates for qualifying air sealing and insulation work. We know which programs are currently active and can help you understand what documentation you need to claim them - reducing your out-of-pocket cost.
We carry full liability insurance and workers compensation on every project. Indiana requires contractor licensing for this work, and we meet those requirements. The{' '}Building Performance Institute certifies home energy professionals to the standards we follow - training that ensures the work is done right, not just fast.
These are not talking points - they are the things that determine whether you actually see the savings and comfort you are paying for. We want you to be able to verify the work, not just trust it.
Insulating basement walls and rim joists addresses one of the biggest sources of heat loss and moisture entry in older Indiana homes.
