Gaps in your attic floor let heated air escape all winter long. We seal every penetration so your furnace runs less, your upstairs stays warm, and ice dams stop forming on your Burlington roof.
Attic air sealing in Burlington finds and plugs the gaps, cracks, and holes in your attic floor that let heated air rise out of your living space - most jobs take one day and can be done without you leaving your home.
Most Burlington homes lose the majority of their heat through the attic, not the walls. Gaps around recessed light fixtures, plumbing pipes, electrical wires, chimneys, and the attic hatch are the biggest offenders in older homes. If your Burlington house was built before 1980, there is a strong chance it has never been properly sealed - and every Burlington winter since then has been pulling heated air straight through those gaps. Attic air sealing is a different job from adding insulation. Insulation slows heat from moving through solid surfaces; air sealing stops air from bypassing the insulation entirely through gaps. Doing one without the other leaves a lot of performance on the table, which is why many Burlington homeowners pair this work with broader air sealing services covering the full building envelope.
Ice dams - the thick ridges of ice that build up along your roofline in January and February - are caused by warm air escaping through your attic floor and heating the roof deck from below. Burlington gets enough snow and cold that even a moderately leaky attic will produce ice dams year after year. If you have had to hire someone to remove ice or noticed water stains on ceilings after a thaw, attic air sealing is the fix to look at.
When conditioned air escapes through the attic floor, the rooms closest to the attic are the first to feel it. If the upstairs bedrooms never quite warm up no matter where you set the thermostat, or if the second floor feels stuffy and hot in July, the attic is the most likely place to look. This is one of the most common complaints Burlington homeowners report before getting air sealing done.
Hold your hand near a recessed ceiling light on a cold day. If you feel cool air coming down, that fixture is connected directly to your attic. The same is true for the hatch or pull-down stairs leading to your attic - if the door feels cold to the touch in winter, it is not sealed properly. These are easy things to check yourself and are reliable signs that air sealing work is needed.
Burlington's heating season runs from October through April - a long stretch where every gap in your attic floor is costing you money every day. If neighbors in comparable Burlington homes pay noticeably less to heat their houses, air leakage is one of the most likely culprits. If you have added insulation in the past but still feel like you are heating the outdoors, unsealed gaps are probably the reason.
A proper attic air sealing job starts with a thorough assessment - often a blower door test that depressurizes the house and makes leaks easier to find. We then work from inside the attic, applying spray foam to larger gaps and caulk to smaller cracks around every penetration: light fixtures, plumbing pipes, electrical wires, chimneys, dropped soffits, and the attic hatch itself. The work is methodical. A good crew checks their work as they go rather than rushing through. Most Burlington jobs are completed in one day. We also pair attic air sealing with retrofit insulation when the attic floor needs both sealing and additional material to reach the right insulation level for Vermont's climate.
Burlington's housing stock - particularly homes in the Hill Section, the Old North End, and the South End - presents specific challenges: cathedral ceilings, knee walls, dormers, finished attics, and additions that were built at different times. We assess each home individually before quoting. If you have a complex attic, we will tell you what that means for the scope and cost before you commit to anything. We are also familiar with Efficiency Vermont's rebate programs and the Vermont Weatherization Assistance Program, and we help qualifying homeowners navigate both.
Best for homes where the main leakage points are around fixtures, pipes, wires, and the attic hatch - a focused seal of every gap in the attic floor.
Ideal for homeowners who want to know exactly how leaky their home is before deciding what work to prioritize - a diagnostic tool that guides the sealing strategy.
Suited for Burlington homes with pull-down stairs, knee walls, or finished attic spaces that create large but often overlooked air leakage paths.
Combines air sealing with blown-in insulation in the same visit - for homeowners who want to address both problems and maximize Efficiency Vermont rebate eligibility.
Burlington averages around 8,000 heating degree days per year - among the highest in the continental United States. That means your furnace runs hard for a long time every year, and every gap in your attic floor is costing you money every single day from October through April. Burlington homeowners feel the impact of a leaky attic more directly than almost anywhere else in the country, and they feel the savings more directly too. The city's housing stock - a large share built before 1980, with many dating to the early 1900s - was constructed with no thought for air sealing. Gaps around pipes, wires, and chimneys were simply left open. Ice dams, a direct consequence of attic air leakage in Burlington's heavy-snow winters, cause damage to gutters, shingles, and ceilings that costs far more to fix than the sealing work that would have prevented it.
Efficiency Vermont - the nation's first statewide energy efficiency utility - offers rebates for insulation and air sealing work done by qualified contractors, and Burlington residents who qualify for the Vermont Weatherization Assistance Program may receive a complete weatherization package at little or no cost. Homeowners in South Burlington and Winooski face similar conditions and also qualify for these programs. A contractor who works in this market regularly will know the current rebate amounts and help you access them before work begins.
When you reach out, we ask a few basic questions about your home's age and what is prompting your call. We reply within one business day and schedule an initial visit - demand picks up in the fall, so earlier is better if you want work done before Burlington's heating season peaks.
We walk through your attic and the rooms below. Many assessments include a blower door test that depressurizes the house and makes leaks easier to locate. The visit takes one to two hours. You get a written estimate based on what we find - no pressure to decide on the spot.
The crew works from inside the attic, applying foam and caulk to every gap found during the assessment - fixtures, pipes, wires, chimneys, and the hatch itself. You can stay home. There is no strong smell and no disruptive noise. Most Burlington jobs finish in a single day.
Before we leave, we walk you through what was done and answer any questions. If you are applying for Efficiency Vermont rebates, we provide the documentation you need or handle the submission. Your home is ready to use immediately - no curing or waiting period.

A large share of Burlington's housing stock dates to before 1940 - irregular framing, finished attics, knee walls, and decades of accumulated penetrations. We know what to look for in these homes and how to seal them properly without causing damage to the character of the structure.
We work with Efficiency Vermont's rebate programs regularly and help qualifying homeowners access the money they are entitled to.
