88.7% of Burlington’s housing is detached single-family houses, and 92.8% of occupied homes are owned by the people living in them. There are no buildings of twenty units or more in town. Almost every insulation decision in Burlington is made by one household about one house, with no association or landlord in the way.
Those houses are mostly young. The median dates from 1981; 33.8% was built in the 1980s and 90s and 18.3% since 2000, against 28.9% from the 1960s and 70s, 11.3% from the 1940s and 50s and 7.8% from before 1940, so 48.0% predates 1980. The fuel is delivered: 68.3% of homes heat with fuel oil or kerosene and 12.7% with bottled gas, while utility gas heats 2.2%, electricity 11.0% and wood 3.5%.
The houses we insulate in Burlington
Burlington is a rural hill town at the foot of the Berkshires, bordering the Farmington River 20 miles west of Hartford. It sits in Hartford County but in the Northwest Hills Planning Region. Almost half its land is owned by three public water supply companies and the State of Connecticut, including Nassahegon State Forest, the Nepaug Reservoir and Sessions Woods Wildlife Management Area, and Johnnycake Mountain rises to 1,165 feet. The business district runs along Spielman Highway, Route 4, and the town’s fire stations name its corners: Chippens Hill, Whigville and Lake Garda.
The 580 homes of the 1980s and 588 of the 1990s are the core of the work. They are mostly colonials, larger than the houses before them, with a two-story foyer or family room, a bonus room over the garage, recessed lights in most ceilings, and often a forced-air system with its air handler and ducts in the attic. Their walls hold R-11 to R-13 batts; their losses are at the attic plane, the tall walls of the two-story rooms where they face an attic, the bonus room floor and knee walls, and the ducts.
The 700 homes of the 1970s, the largest single decade, are raised ranches, colonials and contemporaries. The raised ranch loses at its above-grade rim and the ceiling of the garage under the bedrooms; the contemporary through cathedral ceilings with batts against the roof deck. The 442 homes of the 2000s and 155 of the 2010s have full walls, and in those the work is usually ducts and sealing, or nothing, and we say which.
Burlington was part of the Farmington Plantation, became part of Bristol in 1785 and a town of its own in 1806, when cottage industries, including several clock-making operations, flourished. Its 269 homes from before 1940 include the Hart’s Corner Historic District and houses such as the John Wiard House and the Treadwell House. We work houses of that age from inside: cellar sill and rim, then the attic floor sealed at the chimney and wall tops, and walls only where a cavity is open and the wiring is sound.
Oil, propane and the ducts in the attic
With 68.3% of the town on oil and 12.7% on propane, most Burlington houses buy their heat by the gallon. The coldest reading on record in town, −25°F, came on 14 February 2016, and on nights like that a house’s leaks decide how hard the boiler or furnace runs and how soon the next delivery is due. The saving from sealing and insulating shows up as fewer gallons, not as a line on a utility bill.
A furnace changes where the heat travels. Whether it burns propane or oil, a forced-air system moves heated air through ducts, and in many 1980s and 90s colonials those ducts run through a vented attic that is close to outdoor temperature in winter. Every leaky joint and thinly wrapped run loses heat into the attic before it reaches a room, and on the hottest days, 100°F on record, the same ducts carry cooled air through an attic far hotter than that.
That makes the attic the first stop in these houses, and the ducts part of the job. Seal the ceiling plane under the insulation; seal the duct joints, the boots where ducts meet the ceiling, the air handler cabinet and the return; insulate the ducts; then bring the attic to depth over and around them. An oil-fired boiler house with baseboard heat has no heating ducts to fix, and its attic and rim joist come first.
Whatever the fuel, the order is the same, because the cheapest gallon is the one the house no longer loses. A tighter house also needs a smaller system, which matters to anyone planning to replace an old boiler or furnace.
We seal before we insulate
Insulation slows heat through a surface. It does nothing for air moving through gaps, and a 1990s Burlington colonial has gaps at every change in ceiling height.
In that house the order is: seal the top plates, chases, recessed lights and bath fans from the attic; put a rigid air barrier on the attic side of the two-story room’s tall walls and seal its edges; seal the ducts and the air handler; block the joist bays under the bonus room’s knee walls and seal the garage ceiling; seal the basement rim joist; then insulate the attic, the tall walls and the bonus room to depth.
If a quote specifies a depth of insulation and never mentions air sealing, it is half a job.
What insulation costs in Burlington
Most of our projects run between $3,500 and $12,500. A 1980s or 90s colonial is priced on its attic area, the two-story room’s attic-side walls, the bonus room and the length of duct to seal, and a large one with ducts in the attic sits toward the top of the range. A raised ranch is priced on its rim and garage ceiling, and a 1970s contemporary higher for its cathedral slopes. A house from the 2000s is often a smaller job.
Open cell foam runs R-3.9 to R-4.2 per inch. Closed cell runs R-6.9 to R-7.1 per inch and also acts as a vapor retarder, which is why it costs more and why it is right in some assemblies and unnecessary in others. All products are manufactured in the United States and meet applicable building code and safety standards. ENERGY STAR says sealing air leaks and adding insulation can save up to 10% on annual energy bills.
Insulation rebates in Burlington
Eversource is Burlington’s electric company and also its gas company, though utility gas heats only 2.2% of homes. Home Energy Solutions is open to customers of Eversource, United Illuminating, Connecticut Natural Gas and Southern Connecticut Gas, whatever fuel heats the house, so an oil or propane home applies through its Eversource electric account. The program is ideally suited to homes of one to four units, and a home served in the last six years is not eligible again yet.
A Home Energy Solutions visit costs a $40 copay, effective 1 April 2026, and is done by an authorized contractor. It begins with health and safety tests, uses a blower door to pinpoint drafts and air leaks, and tests the ducts where there is forced hot air or central air conditioning, which in a ducted Burlington colonial is useful in itself. Air sealing is provided at no cost for up to seven hours, with a $10 hourly fee where a larger home needs more. There may be a waiting list, and the program is subject to available funding.
The 2026 Energize CT insulation rebate pays up to $2.00 per square foot or 75 percent of the total cost, whichever is less, up to a maximum of $10,000, on attic floors, floored-over attics, walls, basement and garage ceilings and rim joists. The insulation must be recommended during a Home Energy Solutions visit, the project approved before installation, and the work performed by an approved contractor from the Energize CT Insulation Installers Network. An attic floor must start at R-19 or less and finish at R-49 or greater, or R-38 where R-49 is not structurally practicable, so a 1990s attic already at R-30 would not qualify on that line. Foam on the underside of a roof deck is not on the list, so ask the program before counting on a rebate for it.
For a household of four on Energize CT’s 2026–2027 figures, $93,681 or less is Income Eligible, with no-cost service and up to 100 percent coverage of insulation costs; $93,682 to $124,908 is Enhanced Incentives, with a no-cost visit and up to $2.50 per square foot, a default range that varies by zip code; and $124,909 or more is the standard program. If your income is close to a limit, ask which tier you are in before you pay a copay.
The rebate is paid only when a contractor in the Insulation Installers Network does the work, so ask any installer, including us, whether they are in that network before you sign. If you want work the rebate does not list, such as foam against a roof deck, we will price the job on its own merits.
The Connecticut Green Bank’s Smart-E Loan finances insulation with no money down, up to $50,000, on an owner-occupied home of one to four units: 6.99% APR for 5, 7 or 10 years, 7.49% for 12, and 7.99% for 15 where the lender offers that term. It is arranged through participating contractors, so ask whether yours participates. There is no federal tax credit for insulation installed in 2026; Section 25C ended for anything placed in service after 31 December 2025. Our Connecticut rebate guide has the rest.
Code and climate in Burlington
48.0% of Burlington’s homes were built before 1980. Burlington is in climate zone 5A, like every Connecticut town; its place in the Northwest Hills Planning Region does not change that.
New homes and additions with applications filed since 1 October 2022 follow the 2022 Connecticut State Building Code, which adopts the 2021 IECC with state amendments. The prescriptive values are R-60 for ceilings, with R-49 allowed where it runs at full, uncompressed height over the wall top plate at the eaves; wood-frame walls of R-30 cavity, R-20 cavity plus R-5 continuous, R-13 plus R-10 continuous, or R-20 continuous; R-30 floors; basement walls of R-15 continuous, R-19 cavity or R-13 cavity plus R-5 continuous; and U-0.30 windows. A new home must pass a blower-door test at 3.0 air changes per hour at 50 pascals on the prescriptive path, and never worse than 5.0. Connecticut’s next code, based on the 2024 IECC, has been adopted in draft, but its effective date has been delayed.
Common questions about insulation in Burlington
Do you install insulation in Burlington, CT?
Yes, across town, from Whigville and Chippens Hill to Lake Garda. Most of the work is the colonials of the 1980s and 90s, 33.8% of the housing, with their two-story rooms, bonus rooms and attic ducts. We also insulate the 1970s raised ranches and contemporaries, houses built since 2000, and the older houses around Hart’s Corner, which we work from inside. With nearly every home owner-occupied, the decision is usually yours alone.
How much does insulation cost in Burlington?
Most projects run $3,500 to $12,500. A 1980s or 90s colonial is priced on its attic area, the attic-side walls of a two-story room, the bonus room over the garage and the ducts, and a large house with ducts in the attic sits toward the top of that range. A raised ranch is priced on its rim and garage ceiling, and a contemporary costs more for its cathedral slopes.
Are there insulation rebates in Burlington?
Yes, through Energize Connecticut. Eversource supplies Burlington’s electricity and gas, and an oil- or propane-heated home opens a Home Energy Solutions visit through its Eversource electric account, with a $40 copay on the standard tier. Insulation recommended at that visit, approved before installation and installed by an Energize CT Insulation Installers Network contractor can earn up to $2.00 per square foot or 75 percent of cost, whichever is less, to $10,000, where the existing levels qualify. A 2026 job carries no federal tax credit.
The two-story family room in our Burlington colonial never warms up. Why?
Usually because two of its tall walls face attic space, not the outdoors or another room. Where the room rises past the second floor, the wall beside the bonus room attic or over the garage is often framed with batts and no air barrier on the attic side, so the batts sag and air washes through them. Warm air also rises to that high ceiling and leaks out around its lights. We sheathe and seal the attic side of those walls, insulate them, and seal the ceiling above.
Free estimate in Burlington
Our free estimate is a walk-through, separate from Home Energy Solutions, and it does not qualify a house for any rebate. In a 1980s or 90s colonial we spend most of the time in the attic, at the plates, lights, ducts and air handler and behind the tall walls of the two-story room, then the bonus room and the basement rim. In a raised ranch we look at the rim and garage ceiling. A written scope and price follow, with no charge and no obligation.
Call 914-825-6824, 8am–8pm, seven days, or use the contact form. We work out of New Rochelle, NY, with a 100-plus in-house crew that never subcontracts.
