Even thick attic insulation cannot stop air from flowing through the gaps beneath it. We seal every opening in your attic floor so your furnace stops fighting a losing battle all winter long.
Attic air sealing in Lafayette, IN involves finding every gap, crack, and opening in your attic floor and plugging them with foam or caulk - most residential jobs are completed in one to two days and your living space is untouched throughout.
Insulation slows heat from moving through solid surfaces, but it cannot stop air from flowing through gaps. Most homes have dozens of small openings around light fixtures, plumbing pipes, electrical wires, and wall tops where the attic floor meets the framing. Warm air from your living space rises, finds those openings, and escapes into the attic continuously - taking your heating dollars with it. Sealing those openings first is what makes the insulation above them actually perform. For older Lafayette homes, where the attic floor was often never sealed at all, this work can make a noticeable difference on its own. Pairing sealing with better insulation depth produces even stronger results, and our air sealing services can extend the same gap-closing work to walls and other areas beyond the attic.
If your crawl space is also a weak point in your home's envelope, we can discuss a crawl space vapor barrier as a complementary step that addresses moisture coming from below at the same time you close the leaks above.
If your gas or electric bill in the coldest months feels out of proportion to the size of your home, air leaks in the attic are one of the most common reasons. Lafayette winters drop into the single digits, and a home that is properly sealed holds heat much more efficiently than one where air moves freely between the living space and the attic above. The difference shows up on your bill.
If the bedrooms at the top of your home feel colder than the rest of the house even when the heat is running, warm air is likely escaping through the ceiling into the attic above. This is especially common in older Lafayette homes where the attic floor was never sealed. It is not a furnace problem - it is an air problem, and sealing fixes it.
Ice dams form when warm air escaping from your living space heats the roof unevenly, melting snow that then refreezes at the cold eaves. Lafayette gets enough cold snaps and winter precipitation that ice dams are a real concern here. If you had them last year, attic air sealing addresses the root cause before the next winter arrives - not just the symptom.
If you see dust rings around recessed lights or ceiling fans, or notice a stale smell near the ceiling in winter, air is moving through gaps in your attic floor. That air pulls dust, insulation fibers, and sometimes attic odors down into your living space. It is a sign that the boundary between your home and your attic is not as solid as it should be.
Our crew moves or temporarily shifts any existing insulation to expose the attic floor, then works systematically across the space sealing every gap they find - around pipes, electrical wires, light fixtures, wall top plates, chases, and any other opening where conditioned air can escape. We use spray foam for larger gaps and fire-rated caulk or acoustical sealant where the opening requires a more precise application. After sealing is complete, the insulation goes back down. If the insulation level is thin, we will discuss adding depth during the same visit. For homeowners who want to extend this work beyond the attic, air sealing services covers the rest of the home envelope - walls, basement rim joists, and other leakage points.
For homes where crawl space moisture is also a concern, we pair attic sealing with a crawl space vapor barrier to address both the top and bottom of the building envelope in a single project. Sealing the attic floor without addressing crawl space moisture is sometimes only half the solution in older Lafayette homes, especially those with dirt-floor crawl spaces or poor drainage near the foundation.
Best for homes where heating bills are high, rooms feel drafty, or the attic floor has never been sealed - covers all penetrations from pipes and wires to light fixtures and wall plates.
Suited for homes that have had partial work done previously and need specific high-leakage areas addressed without a full attic project.
Combines sealing with adding insulation depth in the same visit - the most efficient path when the attic floor is thin and leaky at the same time.
The most complete envelope solution for older Lafayette homes where both attic leakage and crawl space moisture are contributing to comfort and efficiency problems.
Lafayette winters regularly drop into the teens and single digits, and the heating season runs from October through April. In a home where the attic floor has never been sealed - which describes a large share of Lafayette's housing stock built before 1980 - warm air rises all day and all night through the same gaps it has been escaping through for decades. Many of the homes in older neighborhoods near downtown, along the river bluffs, and in the areas near Purdue University were built before energy efficiency was a design consideration, and their attics often have no air sealing at all under the insulation. Homeowners in West Lafayette face the same problem - many of the older homes near campus have attics that have never been touched since they were built.
Indiana's humidity swings also make attic air sealing a moisture management tool, not just an energy upgrade. When warm, humid air from your living space escapes into a cold attic in winter, it can condense on the wood framing and roof sheathing and cause problems over time. A contractor doing attic air sealing in Lafayette needs to understand this and seal in a way that keeps the attic properly ventilated even as leaks are closed. Homeowners in Frankfort deal with the same climate dynamics, and attic air sealing delivers the same protection across Clinton County and the broader north-central Indiana region.
Reach out by phone or contact form and we will get back to you within one business day. We will ask a few basic questions - the age of your home, whether you have had any energy audits done, and what is prompting the call - so we can give you a realistic sense of what the job involves before we arrive.
We go up into the attic to look at how much insulation is there, where the obvious gaps are, and whether there are any complicating factors like HVAC equipment or exhaust fans venting into the attic space. This visit takes 30 to 60 minutes and you receive a written estimate before any work is scheduled.
The crew moves existing insulation aside to expose the floor, then works systematically across the space sealing every penetration they find. The work is done entirely above your ceiling. You can stay home throughout - most jobs are completed in a single day.
Once the sealing is done, insulation goes back down and we do a walkthrough with you. We show you photos of the work so you have a clear record of what was sealed and where. The materials are permanent and require no maintenance - the only follow-up is confirming your insulation depth is adequate, which we discuss before leaving.
We reply within one business day and provide free written estimates with no obligation to proceed.
(765) 742-7807A large share of our attic projects are in homes built before 1980 - the type where the attic floor has never been sealed, the insulation is uneven, and previous work may have been done without attention to the gaps underneath. We know what to look for in these homes because we work in them every week.
We serve 12 cities and towns across Indiana, from Lafayette and West Lafayette to Frankfort, Logansport, and beyond. That regional footprint means we understand how the local climate and housing stock affect attic air sealing work across Tippecanoe County and the surrounding area.
Attic work is hidden once insulation goes back down. We take photos before and after sealing so you have a clear record of exactly what was done and where. This protects you if questions ever arise and gives you documentation that adds value when you sell your home.
Sealing the attic floor should not block the vents in your soffits or roof ridge that keep the attic breathing. We seal the leaks between your living space and the attic while making sure the attic itself stays properly ventilated - getting that balance right matters in Indiana's climate, where humidity swings are significant.
The Building Performance Institute certifies contractors in building science and energy efficiency - including the whole-home approach that makes attic air sealing most effective. Duke Energy Indiana also offers rebate programs for qualifying air sealing work through their home energy improvement programs - ask us about the documentation needed to qualify when you request your estimate.
