Serving Stillwater, OK and surrounding areas. (405) 338-4339
Oklahoma wind forces outside air into your home through gaps you cannot see. We find and close them so the air you pay to heat and cool actually stays inside where it belongs.
Air sealing services in Stillwater find and close the small gaps, cracks, and openings in your home where outside air sneaks in and conditioned air leaks out - most jobs take one full day and you can stay in the house. Insulation slows heat transfer but does not stop air movement. If your home has gaps around outlets, along the attic floor, or where pipes enter walls, outside air flows right through regardless of how much insulation is in place.
Stillwater has a significant stock of homes built in the 1950s through 1980s, mostly in neighborhoods tied to the growth of Oklahoma State University. Those homes were never designed to be airtight, and decades of small repairs, added wiring, and plumbing penetrations have made things worse over time. If your home is more than 30 years old and has never had an energy audit, the odds are high that there are gaps that have never been addressed.
Air sealing and insulation work best together. If your home needs better coverage in the basement as well, our basement insulation service addresses the rim joists and above-grade walls that are among the most common sources of heat loss in older homes.
If your OG&E or Oklahoma Natural Gas bill climbs sharply when the weather turns extreme and your usage habits have not changed, air leakage is one of the most common causes. Stillwater's climate swings are severe enough that even moderate leakage can translate into noticeably higher bills during peak heating and cooling months.
If one bedroom is always stuffy in August or one corner of the living room is always cold in January, that is a classic sign of air infiltration near that space. In older Stillwater homes, this often traces back to gaps in the attic above that room or around the wall framing where it meets the floor. Turning up the heat or AC rarely fixes it - sealing the source does.
Hold your hand near an electrical outlet on an exterior wall on a windy day. If you feel air movement, outside air is coming directly through the wall cavity. Oklahoma's persistent south and north winds make this test especially revealing here - what might be a subtle draft in a calmer state becomes obvious when a strong wind is blowing.
If your home was built before the early 1990s and no one has ever assessed where air is leaking, significant gaps almost certainly exist. This is especially true for homes in Stillwater's older neighborhoods near campus that have had multiple owners, small repairs over the years, and new penetrations for wiring and plumbing that were never properly sealed.
We start every job with a blower door test - temporarily mounting a fan in one of your exterior doorways to depressurize the house and reveal exactly where air is moving through the building envelope. That test takes the guesswork out of the work and ensures no major leak gets missed. The crew then seals attic bypasses, rim joists, penetrations around pipes and wiring, and the perimeter of the home using foam, caulk, and weatherstripping depending on the size and location of each gap. We finish with a second blower door test to confirm the leakage rate actually dropped.
We also offer attic air sealing as a standalone service for homeowners who want to address the attic plane specifically - the area where wall framing meets the attic floor accounts for the largest single source of air loss in most homes. And we pair air sealing with basement insulation when a home has both airflow and thermal problems at the foundation level, since addressing them together in a single visit is almost always more efficient.
Suits homes with drafts, high bills, and uneven temperatures throughout - addresses the full building envelope.
Suits homeowners who want to target the single biggest source of air loss in most older homes.
Suits homes where cold drafts at floor level or moisture from below are the primary complaints.
Suits any homeowner who wants measurable proof the work was done - before and after numbers on paper.
Stillwater sits in a climate that swings hard in both directions - summer highs regularly push past 95 degrees and winter cold snaps can drop temperatures well below freezing. That means your home is fighting heat gain in July and heat loss in January, and any gap in the building envelope is costing you money in both seasons. Air sealing here pays off faster than it would in a milder climate because your HVAC runs hard for a long stretch of the year.
Oklahoma is also one of the windiest states in the country. Wind creates pressure against your home's exterior, forcing air through every gap it can find. A gap that might cause a minor draft in a sheltered location can become a significant source of heat loss here when a strong north or south wind is blowing. We serve homeowners throughout Payne County and across north-central Oklahoma - including Owasso and Bartlesville, where the same wind-driven air infiltration issues show up in older homes throughout the region.
We will ask about your home's age, whether you have an attic and crawl space, and what is prompting you to call. This helps us arrive prepared with the right equipment. We respond within 1 business day.
We mount a fan in your front door to measure exactly how much air your home is losing and pinpoint where the biggest leaks are. This test takes the guesswork out of the job - no major leak gets missed.
After the assessment you receive a written estimate explaining what areas will be treated, what materials will be used, and what realistic results you can expect - not just a list of tasks.
The crew works in the attic, crawl space, and around the interior perimeter using foam, caulk, and weatherstripping. After work is complete we run a second blower door test to confirm the leakage rate actually dropped.
Free blower door assessment. Written estimate before any work starts. Before-and-after test results included.
(405) 338-4339Stillwater Insulation is licensed through the Oklahoma Construction Industries Board, the state body that sets minimum standards for contractors statewide. That license gives you accountability - a place to turn if anything is not right.
We run a blower door test before we start and again when we finish, so you have a measurement - not just a promise - showing how much the leakage rate dropped. That documented result is yours to keep for your records.
We work throughout Payne County and across the surrounding region, covering 12 service areas from Stillwater to the Oklahoma City metro. Local contractors know the housing stock, the climate, and what Oklahoma wind actually does to a home.
Both Oklahoma Gas and Electric and Oklahoma Natural Gas have offered rebate programs for qualifying energy efficiency work. We know what documentation those programs require and can help you get it before the crew leaves.
The Building Performance Institute standards we follow require thorough sealing of the attic plane, crawl space rim joists, and all penetrations through the building envelope - not just a pass at windows and doors. That approach, combined with verified before-and-after results, gives you confidence that what we do makes a real difference.
Address the rim joists and above-grade walls in your basement - one of the most common sources of heat loss that air sealing alone cannot fully fix.
