Serving Burlington, VT and surrounding areas. (802) 307-1480
Burlington Insulation Company provides air sealing, attic insulation, and basement insulation throughout Montpelier, VT - serving the Victorian homes, pre-war Colonials, and multi-family rental properties across Vermont's capital city with a one business day response time.
Most of the homes on Montpelier's older streets were built before anyone thought about airtightness - wood framing, plaster walls, and decades of settling have left these houses full of hidden air paths. Our air sealing services use a blower door test to find where your home is actually losing air, then close those paths with the right materials - so you are fixing the real problem, not just adding insulation on top of leaks that are still running.
Montpelier's steep-roofed Victorian and Colonial homes are exactly the building type most prone to ice dams - and inadequate attic insulation is the underlying cause in almost every case. Bringing the attic depth to Vermont's required level, after sealing the air paths, stops the heat escape that drives ice dam formation and reduces what it costs to keep the living space below warm through a central Vermont winter.
Montpelier homes near the Winooski River and its north branch have seen flooding more than once, and stone or brick foundations in these older homes absorb and transmit moisture more readily than poured concrete. Properly insulating the basement in a Montpelier home means addressing the moisture history first, then choosing a material - typically closed-cell spray foam - that adds a vapor-resistant layer rather than trapping moisture behind it.
The rim joist at the top of a Montpelier home's foundation wall is one of the most reliable heat-loss points in older New England construction. Spray foam applied to those framing bays seals the gaps between the foundation and the wood frame above it - stopping the cold air infiltration that makes first-floor rooms uncomfortable all winter and that drives up fuel bills from October through April.
Many of Montpelier's duplexes and converted single-family rentals have not had insulation work done in decades, and the attics in those buildings often show original material that has compressed well below any useful depth. Blown-in loose-fill is the fastest and least disruptive way to bring that depth up in an occupied building - no opened ceilings, no extended downtime, and a result that meets Vermont's climate zone requirements.
In Montpelier's older homes, the attic floor is where heat escapes most freely - through gaps around chimney chases, plumbing vents, electrical boxes, and the pull-down attic hatch. Sealing those individual paths before adding insulation above them is the step most contractors skip, and skipping it is exactly why new insulation sometimes delivers disappointing results on heating bills.
Montpelier has one of the oldest housing stocks of any city in Vermont. A large portion of the homes here were built before World War II - Victorian-era two-stories, New England Colonials, and converted farmhouses with plaster walls, wood clapboard siding, and stone or brick foundations. These are beautiful homes to live in, and they are expensive to heat. They were built without vapor barriers, without modern insulation, and without any concern for airtightness. Over the decades, wood framing shrinks and shifts, plaster cracks, and gaps accumulate in every place where two materials meet - the attic floor, the rim joist, around windows and doors, and behind knee walls. Each one of those gaps is a heat path running from your living space to the outdoors every single day of a Montpelier winter.
Flooding adds another dimension to Montpelier's insulation picture that most other Vermont cities do not share. The city sits where the Winooski River and the North Branch meet, and the 2023 flooding was a stark reminder of what water can do to a home's building envelope - damaged insulation, wet framing, and compromised foundations that need to be assessed carefully before anything new goes in. Even homes that did not flood directly have often dealt with wet basements, high water tables in spring, and the chronic moisture problems that older stone foundations transmit year after year. Knowing the difference between a moisture issue that needs to be fixed first and one that insulation alone can manage is something you only learn from working in these specific buildings.
We work on homes throughout Montpelier - from the streets below Hubbard Park and the hillside neighborhoods above downtown to the in-city blocks closest to the Vermont State House. The homes in Montpelier's city core sit on small lots, often with shared driveways or just a few feet of clearance between buildings - conditions that require careful equipment staging and material delivery. We pull permits through the City of Montpelier when the scope of work requires it and know which projects trigger that requirement before starting.
Barre Street, Berlin Street, and the East State Street corridor are the residential streets we work on most often in Montpelier. Route 2 and Interstate 89 connect the city to the surrounding region, and we serve homeowners across the central Vermont corridor. Our work in nearby Barre, just 8 miles southeast, deals with the same era of housing - pre-war wood-frame homes with stone foundations and decades of deferred insulation work - so we move between the two cities regularly and know what to expect in both. Homeowners further south in Rutland also call on us for insulation work, and we serve that area as part of our regular coverage across Vermont.
Reach out by phone or through the contact form and we will respond within one business day. We will ask a few questions about your home - how old it is, what your biggest complaint is this winter, and whether you have had any flooding or moisture issues. That conversation shapes what we look for when we come out.
We walk through your attic, basement, and any crawl spaces, check for moisture evidence, and run a blower door test if air sealing is part of the picture. For Montpelier's older homes, this step takes the time it needs - we are not just measuring square footage, we are understanding the building. You get a written estimate that explains what we found, what we recommend, and what it will cost before anything is scheduled.
Most air sealing and insulation jobs in Montpelier are completed in one to two days. You can stay in the house during the work - we just need clear access to the attic hatch and basement. If spray foam is being applied in enclosed spaces, we will tell you exactly when those areas are off-limits and for how long. No surprises on the day.
After the job is done, we run a second blower door test so you can see the before-and-after improvement in real numbers. We walk you through what was installed and what we noticed along the way. If your project qualifies for an Efficiency Vermont rebate - which many air sealing and insulation jobs in Montpelier do - we will tell you exactly what to submit so the money does not go unclaimed.
We serve all of Montpelier's neighborhoods. One business day response. Written estimate before anything starts - no pressure, no surprises.
(802) 307-1480Montpelier is the smallest state capital in the United States by population - about 8,000 people - but it carries the administrative and civic weight of the entire state of Vermont. The gold-domed Vermont State House anchors the downtown and has defined the city's character since 1859. State government is the largest employer, which gives Montpelier a more stable, long-tenured homeowner base than many small Vermont cities. The housing stock reflects the city's age - Victorian-era two-stories, New England Colonials, and converted farmhouses fill the neighborhoods that radiate out from the downtown core, with most homes sitting on small in-city lots on streets that were laid out before automobiles were common. Neighborhoods like Berlin Street, the Barre Street corridor, and the streets climbing toward Hubbard Park carry the oldest and most architecturally distinctive housing in the city.
The Winooski River runs through the heart of Montpelier, and every long-term resident knows what it can do when conditions are right. The flooding in the summer of 2023 was the most severe in recent memory, damaging hundreds of homes and businesses in the lower sections of the city. That event reshaped how many Montpelier homeowners think about their basements, foundations, and building envelopes - and it made the conversation about proper insulation and moisture management more urgent than it had been in years. We serve homeowners across the full city, and our nearby work in Barre - just down Route 302 - means we move through this part of central Vermont regularly. We also serve homeowners further south in Rutland as part of our broader Vermont coverage.
