Insulation alone does not stop air from leaking through gaps in your home. We find and seal those openings so your heating and cooling dollars actually stay inside your house.
Air sealing services in Reno close the small gaps, cracks, and openings where conditioned air escapes and outside air enters, delivering measurable improvements in comfort and energy cost. Most single-family homes in Reno are completed in one day, and a blower door test confirms the results before the crew leaves.
Insulation slows the movement of heat through walls and ceilings, but it does not stop air from flowing through gaps. Think of insulation as a sweater and air sealing as a windbreaker: you need both to stay warm when it is cold outside. In Reno, where temperatures swing more than 100 degrees across the year, those gaps cost real money in both summer and winter. They are also the reason wildfire smoke enters homes that appear to have all their windows and doors closed.
Air sealing is often combined with attic air sealing for attic-specific work, and with insulation upgrades for the full package. Doing both in the same visit is more efficient and typically unlocks higher rebate amounts from NV Energy.
If your energy bill climbs sharply from October through February and your home never quite feels warm even with the thermostat set high, air leaks are a likely cause. Reno winters are cold and dry, and a leaky home forces your furnace to run almost constantly to keep up. If your bills seem high compared to neighbors with similar-sized homes, it is worth having someone take a look.
Stand near your baseboards on a cold January morning and notice whether you feel a chill from below. In older Reno homes, the gap between the foundation framing and the floor above is one of the most common places for cold air to enter. Drafts near electrical outlets on exterior walls are another sign. They are small openings individually, but there are a lot of them across an older home.
If you notice smoke odor inside your home during a bad air quality day, even with all windows and doors shut, outdoor air is finding its way in through gaps you cannot see. This is increasingly common in Reno given recent wildfire seasons in the Sierra Nevada region. It signals that your home has openings that air sealing could close, improving both energy efficiency and indoor air quality.
If you find yourself dusting more than seems reasonable, or notice dust streaks near ceiling fixtures or baseboards, your home may be pulling in unfiltered air from the attic or crawl space. That air carries dust, insulation particles, and other debris. Sealing those pathways reduces how much of that material circulates through your living spaces and lands on your furniture.
Reno Insulation performs whole-home air sealing with a focus on the areas that deliver the greatest return: the attic floor, rim joists near the foundation, and the penetrations where plumbing, electrical, and HVAC lines pass through the building envelope. These are the locations where the majority of uncontrolled air movement happens in most Reno homes, and sealing them first produces the most measurable improvement on a blower door test.
We use a blower door test to measure your home before the work begins, which gives you a baseline and allows the crew to locate leaks precisely. After the work is done, we run the test again so you can see the actual improvement in numbers. That before-and-after data is also the documentation most commonly required for NV Energy rebate claims and federal tax credit filings.
Air sealing is frequently paired with basement insulation to address the lower building envelope in the same visit, and with attic air sealing for targeted work at the top of the home where heat loss is typically greatest.
Best for homeowners who want a complete assessment and the highest measurable improvement in a single project.
Best for homes where heat loss through the ceiling and attic floor is the primary concern, common in older Reno construction.
Best for homes with cold first floors or drafty lower rooms, where air enters at the joint between the foundation and the floor framing.
Best for homes with visible gaps around plumbing, electrical, or HVAC lines that pass through walls, floors, or ceilings.
Reno sits at roughly 4,500 feet in the high desert, and its temperature range from below 10 degrees in January to over 100 degrees in July means your heating and cooling systems work hard in both directions all year. Every gap in your home's envelope is costing you money in both seasons. Homeowners in milder climates can get away with a leaky home more easily; in Reno, the payback on air sealing is faster because the extremes are more severe.
A large share of Reno homes were built between the 1950s and 1980s, before modern energy standards existed. Neighborhoods like Midtown, the Old Southwest, and areas near the University of Nevada campus have homes that were never designed with tight construction in mind. Reno's dry desert air also causes wood framing to shrink and pull away from surrounding materials over decades, opening gaps that were not there when the house was built. The ENERGY STAR Seal and Insulate program identifies homes built before 1990 as the most likely to benefit from air sealing, which describes a large portion of Reno's housing stock.
Reno also experiences wildfire smoke events that have grown in frequency and severity, and a well-sealed home keeps that outdoor air where it belongs. We serve homeowners throughout the area, including Sparks, Carson City, and Dayton, and we bring the same blower door testing process to every job regardless of location.
Reach out by phone or contact form and we will get back to you within one business day to schedule an assessment. Demand picks up in the fall, so earlier is better if you want to be ready before winter.
Before any work begins, we run a blower door test to measure exactly how leaky your home is. This takes about 30 minutes and gives you a number you can compare to the result after the work is done.
The crew spends most of the day in your attic and crawl space, which means minimal disruption to your home. Foam, caulk, and backer material are used depending on the gap size and location.
A second blower door test shows the improvement in measurable terms. You receive written documentation of the work done, which is required for NV Energy rebate claims and federal tax credit filings.
Free estimate. Blower door testing included. No pressure to sign until you are ready.
(775) 491-3183We test your home before the work and again after, so you see the actual improvement in numbers. That data tells you exactly what you got for your money, and it is the documentation required to file NV Energy rebates and federal tax credit claims. See Building Performance Institute standards.
The attic floor and rim joists account for the large majority of air leakage in most Reno homes. We target those areas first, then address penetrations and bypasses throughout the rest of the building. That prioritization means you get the most measurable result per dollar spent.
Reno homeowners face smoke events that most contractors elsewhere have never thought about. We seal with those conditions in mind, closing the attic and crawl space pathways that let outdoor air, and smoke with it, enter homes that appear buttoned up tight.
Reno Insulation has been working on homes throughout the Truckee Meadows area since we opened. That history means we understand the housing stock, the utility rebate process, and the seasonal demand patterns that affect scheduling in this market. You are not working with a national franchise that has never seen a Reno winter.
Measurable results, documented work, and local experience are the three things that separate an air sealing job you can trust from one that leaves you guessing. Those are the standards Reno Insulation brings to every project, whether the home is a 1950s bungalow near the University or a newer build in South Reno.
Insulating the basement walls and rim joists pairs directly with air sealing to close the lower building envelope where cold air most often enters.
