Drafty rooms and rising energy bills are often caused by hidden gaps in your home, not just missing insulation. We find every leak with a blower door test and seal it with documented results.
Air sealing services in Elmira find and close the gaps, cracks, and hidden openings where outside air sneaks in and heated air leaks out, most projects take one to two days and cover the attic floor, basement rim joist, and penetrations around pipes and wires throughout the home.
Most homeowners assume drafts come through windows and doors, but the biggest air leaks in a typical Elmira home hide in places you never see - the attic floor, the space where pipes pass through ceilings, and the rim joist sitting on top of your foundation wall. These gaps have usually been there since the house was built, and in Elmira's older housing stock that can mean decades of cold air moving freely through your home's shell. Air sealing closes those paths for good.
Air sealing works best when paired with the right insulation on top of it. If your home also has thin or missing insulation in the attic, combining air sealing with our basement insulation or attic air sealing service lets you address both problems in the same project - which is more efficient and often reduces the combined cost.
If your gas or electric bill has crept up year after year without any change in your habits or home size, air leakage is one of the most common culprits. Elmira winters are long and cold, and a leaky home forces your furnace to run almost constantly. You are essentially paying to heat the outdoors.
If one or two rooms stay cold no matter how high you set the thermostat - especially rooms above a garage, at the end of a hallway, or on an upper floor - air leakage is often the reason. Cold air is finding a way in and your heating system cannot overcome it. This is especially common in Elmira's older homes where gaps in the framing have opened up over decades.
Hold your hand near an electrical outlet on an exterior wall on a cold day. If you feel cool air, that outlet is connected to the outside through gaps in the wall. The same test works around baseboards, the attic hatch, and the basement door. These are direct signs that outside air is moving freely through your home's shell.
Condensation on attic framing in winter, frost on the underside of the roof deck, or a persistent musty smell in the basement can all indicate that warm moist air from your living space is leaking into areas where it should not be. In Elmira's cold and humid climate, this can cause mold and wood damage over time if left unchecked.
We start every air sealing job with a blower door test - a pressurization method that finds exactly where air is moving through your home's shell. That measurement drives the work, so we are targeting the leaks that actually matter rather than applying foam in obvious spots and hoping for the best. After sealing, we run the test again to confirm the leakage rate dropped. You get a before-and-after result, not just a contractor's word.
For homes where air sealing reveals significant heat loss in specific areas, we can combine the work with basement insulation or attic air sealing in the same visit. Bundling the work is more efficient and often reduces the total cost. We give you a written estimate covering exactly what will be done before any work begins.
Best for homeowners who want a measured, documented picture of their home's air leakage before and after sealing - not just an estimate.
Suited for homes where warm air is rising into the attic through gaps around ceiling fixtures, framing, and duct penetrations.
Designed for homes where cold air enters from the basement perimeter - a major source of drafts and heat loss in Elmira's older housing stock.
Comprehensive sealing of all identified leakage points throughout the home - attic, basement, and living areas - in a single coordinated project.
Elmira regularly sees temperatures well below freezing from November through March. The colder the outside air, the harder your heating system works to replace warm air leaking out. For a city where a large share of the housing stock was built before 1960 - before air-sealing techniques were part of standard construction - the gap between what these homes are and what they could be is significant. Decades of settling, renovation, and wear have opened up pathways throughout the building shell that simply did not exist when the house was new. Air sealing closes those pathways and gives your heating system a fair fight.
Homeowners in Waverly and Horseheads face the same conditions. New York State's efficiency programs, administered through NYSERDA, are actively available to homeowners throughout the Southern Tier and can cover a meaningful portion of the cost for certified air sealing work. Homes near the Chemung River may have additional moisture considerations - we check for signs of past water intrusion before sealing any area, because closing off a damp space without addressing moisture first can make things worse. The U.S. Environmental Protection Agency provides guidance on maintaining healthy indoor air quality alongside efficiency improvements.
We ask a few basic questions: the age of your home, how large it is, and what is prompting you to call - high bills, drafts, or a specific room that is always cold. You will hear back within one business day to schedule a visit.
A trained contractor runs a pressurization test to measure how much air your home is losing and find exactly where it is coming from. This step usually takes two to three hours. You leave with a written estimate that explains what was found and what will be sealed.
The crew applies foam and caulk to close gaps around pipes, wires, framing, and other penetrations. Most of the work happens in spaces you do not use daily. A typical job takes one to two days and disruption to your living areas is minimal.
Once sealing is done, we run the blower door test again to confirm the leakage rate actually dropped. You receive a documented summary of the before-and-after results. If you qualify for NYSERDA rebates or federal tax credits, we handle the paperwork.
Free written estimate. Blower door test included. No obligation to move forward.
(607) 302-4623A blower door test at the start tells us exactly where the air is going. A second test after the work confirms the leakage rate dropped. That before-and-after measurement is what separates documented results from a contractor's word. You receive a written summary of both readings.
New York State's efficiency programs are actively used in the Southern Tier, and we are enrolled to help homeowners access those rebates without extra hassle. If your project qualifies, we handle the paperwork on your behalf. The Building Performance Institute sets the certification standards that program participation requires.
Homes built before 1960 - which describes much of Elmira - have leakage patterns that newer homes simply do not have. We know where to look in these older structures and what complications to check for, including moisture in areas near the Chemung River where past flooding can affect basement conditions.
After the assessment, you get a written estimate explaining what we found and exactly what we plan to seal. Nothing gets done without your approval, and the price you are quoted is the price you pay. We explain everything in plain language before any work begins.
Air sealing is one of those services where the quality of the contractor matters more than most homeowners realize. Done right, with proper testing, the results are measurable and lasting. Done poorly - by someone who skips the test and applies foam in obvious spots - you may spend money without solving the problem.
