Gaps in your home's shell act like a window left open all winter. We find every one and seal it - so your heat stays inside and your bills go down.
Air sealing services in South Burlington close the hidden gaps, cracks, and openings where outside air sneaks into your home - most jobs on a single-family home are completed in one day, with the difference felt on the very next cold or windy night.
Most of the leaks in a South Burlington home are invisible - hidden behind walls, above ceilings, and around pipes and wires. Together they can act like leaving a window cracked open year-round. Vermont's long heating season means those leaks are costing you money every day from October through April. A diagnostic blower door test finds exactly where they are, so we can close them all.
Air sealing and attic air sealing are often done together - the attic floor is the single biggest source of heat loss in most older South Burlington homes, and sealing it can make a dramatic difference on its own.
If you can feel a chill near electrical outlets on exterior walls, around window frames, or along the baseboard, outside air is getting in. This is especially common in South Burlington homes built before the 1980s, where framing and exterior sheathing were not designed to act as air barriers.
When warm air escapes through the attic, cold air gets pulled in at the lower levels to replace it. If your upstairs is consistently harder to heat than the ground floor in winter, that temperature difference is often a sign of significant air leakage at the attic level.
If you have seen frost on your roof sheathing or dark staining on attic insulation or wood in winter, warm moist air from your living space is escaping into the attic. South Burlington's cold winters make this pattern easy to spot - and left unaddressed, it can lead to mold and structural damage.
If your winter bills seem out of proportion to your home's size or what your neighbors pay, air leakage is one of the most common causes. Your furnace or heat pump works much harder than it should when conditioned air is constantly escaping through gaps in the shell.
Every air sealing project starts with a blower door test - a diagnostic tool that shows exactly how leaky your home is and pinpoints where the air is moving. We seal each gap with the right material: spray foam for larger openings around pipes and wires, caulk for smaller cracks, and weatherstripping for moveable parts like doors. We also specialize in attic air sealing, targeting the top plates and ceiling penetrations where most homes lose the most heat.
Many South Burlington homeowners combine air sealing with basement insulation to address both the top and bottom of the home in a single project. Doing both at once qualifies for larger Efficiency Vermont rebates and delivers the most noticeable comfort improvement. We provide a written scope, a before-and-after blower door test result, and all documentation you need for rebate applications.
Full diagnostic and sealing of the entire building envelope - attic, basement, walls, and all penetrations.
Targeted sealing at the attic floor, the most impactful single area in most South Burlington homes.
Closes the gap at the top of the foundation wall where cold air commonly enters basements and crawl spaces.
Combined projects that address both air infiltration and heat transfer - qualifying for the broadest rebates.
South Burlington's proximity to Lake Champlain means the area experiences significant humidity swings between seasons, and repeated freeze-thaw cycles through winter cause building materials to expand and contract. Over time, that movement opens new gaps around window frames, foundation sills, and exterior penetrations - even in homes that were well-sealed a decade ago. South Burlington's heating season runs from October through April, with January and February lows regularly below zero. A leaky home is fighting that cold every single day for six months.
We serve South Burlington and the wider Chittenden County area, including Essex and Colchester, where the same mid-century housing stock presents the same air leakage challenges. Vermont's Efficiency Vermont program offers rebates that homeowners in most other states simply do not have - and we help you capture every dollar you qualify for.

Call or submit a request and we will be back to you within one business day. We ask a few quick questions about your home's age and comfort problems so we can come prepared with the right equipment.
We set up a large fan in your front doorway, lower the air pressure inside, and detect every leak using a smoke pencil or thermal camera. The test takes about 45 minutes and gives you a real number showing how leaky your home is right now.
After the assessment, you receive a clear written quote explaining what will be sealed, what materials will be used, and the total cost. We also review which Efficiency Vermont rebates apply so you know your actual out-of-pocket number before deciding.
We seal every gap identified in the assessment, then run a second blower door test to confirm how much the leakage was reduced. You receive before-and-after test results along with all documentation for rebate applications.
Free written estimate. No pressure. Before-and-after blower door test included so you can see the results for yourself.
(802) 352-8211We measure your home's air leakage before we start and again when we finish. That gives you a real number proving the work was done - not just our word for it. If the result falls short of target, we keep working.
South Burlington's mid-century homes have specific air leakage patterns we have seen and fixed many times. That means we know where to look first and how to reach the gaps that other contractors miss.
Vermont homeowners have access to rebates and financing that most states do not offer. We walk you through the documentation requirements before work begins so you capture every dollar you are eligible for.
We assess your home's ventilation before sealing so controlled fresh air pathways are maintained. A properly sealed home breathes better - not worse - because air comes in through systems designed for it, not through gaps that also carry dust and pollutants.
We are state-licensed and fully insured insulation contractors serving South Burlington and the surrounding area. For technical standards on building performance work, we follow the guidelines published by the U.S. Environmental Protection Agency on Indoor Air Quality to ensure your home is healthier after the work, not just tighter.
