Your home does not need a major renovation to hold heat. We add insulation to attics, walls, and crawl spaces with minimal disruption - so Vermont winters cost you less.
Retrofit insulation in South Burlington means adding insulation to a home that is already built - without tearing out walls or doing major construction. Contractors blow, spray, or inject insulating material into existing spaces like attic floors, wall cavities, and crawl spaces through small openings. Most attic jobs take one day or less. The goal is to stop heat from escaping in winter and entering in summer, which directly lowers your energy bills.
South Burlington developed rapidly in the mid-20th century, and a large share of its housing stock dates from the 1950s through the 1980s. Homes from that era were insulated to minimum standards that look thin by today's requirements - and Vermont demands higher insulation levels than most states. If your home has never had insulation work done, it is almost certainly under-insulated. Pairing this project with home insulation planning gives you a clear picture of every area that needs attention.
The biggest heat losses in most homes happen in the attic, exterior walls, and the floor above an unheated basement or crawl space. Contractors typically start with the attic because it is the easiest to access and delivers the fastest payback. Walls and crawl spaces are also common targets, especially in older homes where original insulation has settled or was never installed properly. If you are also dealing with air leaks, we recommend reading about our spray foam insulation options, which can seal and insulate in a single step for certain areas.
If your gas or electric bills seem out of proportion to the size of your home, poor insulation is one of the most common culprits. South Burlington winters are long and cold, and a home that is losing heat through the attic or walls has to work much harder to stay comfortable. If your bills have been climbing and you have not changed your habits, an assessment is a reasonable next step.
Ice dams - the thick ridges of ice that build up along the edge of your roof - are a classic sign that warm air is escaping through your attic and melting snow unevenly. This is a South Burlington problem: the combination of heavy snowfall and hard freezes creates ideal conditions for ice dams in homes that are not properly insulated. If you have seen them more than once, your attic insulation is almost certainly part of the issue.
If one part of your home always feels drafty or takes too long to warm up, the insulation in that area may be thin, missing, or has settled over time. In older South Burlington homes, this is especially common in rooms above garages, at the ends of the house, or on upper floors. It is a comfort problem before it is an energy problem, and one of the clearest signals homeowners notice on their own.
Homes built in South Burlington before the 1990s were typically insulated to standards that are now well below what is needed for a Vermont winter. If you have owned your home for years and cannot recall any insulation work being done, there is a reasonable chance you are running on original materials that have settled, degraded, or simply were not enough to begin with. A quick attic check can tell you a lot.
We offer retrofit insulation for every area of your South Burlington home - attic floors, exterior walls, and crawl space ceilings or walls. Our most common approach for attics is blown-in insulation, which fills the entire space evenly and can be installed in a few hours without disrupting the rest of your home. For walls, we use dense-pack insulation injected through small holes that are patched before we leave. For crawl spaces, we combine insulation with moisture management to protect against Vermont's freeze-thaw cycle.
A quality retrofit job always starts with air sealing. Blowing insulation over gaps and cracks without closing them first is a common shortcut that leaves homeowners disappointed. We seal before we insulate - every time. If your project involves hard-to-reach rim joists or an irregular crawl space, spray foam insulation is often the right tool. For homeowners looking at a full-home update, our home insulation service walks through every area and sets priorities based on where the biggest losses are.
Best for homes with accessible attic floors where adding depth quickly and evenly delivers the fastest comfort and energy improvement.
Suited for older homes with empty or under-filled wall cavities, using small drilled holes that are patched before we leave.
Ideal for homes with unheated crawl spaces that are pulling cold air into the floor above, combined with a vapor barrier for moisture control.
South Burlington sits in one of the coldest climate zones in the continental United States. The Department of Energy recommends significantly higher insulation levels here than in most other parts of the country - particularly in attics, where heat loss is greatest. If your home was built before the 1990s and has never been updated, there is a good chance it is under-insulated by current standards, and you are paying for that gap every winter. Vermont's heating season is long enough that the difference between adequate and inadequate insulation shows up clearly on your energy bills.
Ice dams are another reason retrofit insulation pays off here. They form when heat escapes through a poorly insulated attic and melts roof snow unevenly - the water runs toward the cold eaves, refreezes, and can push under shingles over time. This is genuinely a Vermont problem, and it is one that proper attic insulation, combined with air sealing, addresses at the root. Homeowners in Colchester and Essex Junction face the same conditions, and we serve the entire Chittenden County area.
Vermont is one of the few states with a statewide energy efficiency utility - Efficiency Vermont - that offers rebates specifically for insulation upgrades. South Burlington homeowners can access these rebates and stack them with the federal tax credit, which meaningfully reduces the cost of a project. The U.S. Department of Energy and Building Performance Institute both publish guidance on insulation standards that apply here.
We ask about your home's age, which areas concern you, and any specific problems you have noticed. This first conversation usually takes under ten minutes, and we reply within one business day to schedule your assessment.
We walk through your home - starting in the attic - to measure current insulation levels and look for air leaks. You come away with a clear written estimate that includes what we plan to install and the R-values we will achieve.
For attic work, the crew arrives with a truck-mounted blower and typically wraps up in a few hours. Wall or crawl space jobs run a full day. We protect your floors and furniture near the work area throughout.
After the job we give you written documentation of the insulation levels installed in each area. We walk you through the Efficiency Vermont rebate process and the federal tax credit so you capture every dollar you are entitled to.
Free estimate. No obligation. We reply within one business day.
(802) 352-8211We never blow insulation over unaddressed air gaps. Sealing first is the only approach that delivers the energy savings homeowners expect - and it is standard practice on every retrofit job we do, not an optional add-on.
After installation you receive written documentation of the insulation levels achieved in each area of your home. This is useful for rebate applications, home sales, and your own peace of mind - you will know exactly what was done.
Our team knows the current Efficiency Vermont rebate programs and can walk you through the paperwork before we start. South Burlington homeowners who work with knowledgeable contractors receive higher rebate amounts and do not miss out on programs that require pre-enrollment.
We factor in ventilation and moisture control on every job. Vermont's freeze-thaw cycle creates conditions where improperly installed attic insulation can contribute to moisture problems over time. We check for moisture issues before installing anything and address them if needed.
These four points add up to one thing: you will know exactly what was done, you will have documentation to prove it, and you will not be left guessing whether the money was well spent. That is the standard we hold ourselves to on every retrofit insulation job in South Burlington.
High-performance foam for rim joists, crawl spaces, and hard-to-reach areas where blown-in material cannot seal and insulate at the same time.
