Heat rising through your attic is costing you money every month from November through April. Proper attic air sealing closes the gaps and keeps your home warmer without raising your thermostat.
Attic air sealing in Norwich, CT means finding and plugging the gaps, cracks, and holes where your home connects to the attic - stopping heated air from escaping, blocking outside air from entering, and protecting your home from the moisture problems that follow - and most residential jobs finish in one to two days.
Norwich has a large share of homes built before 1970, many of which have never had their attic floors assessed for air leaks. These homes were built before energy efficiency was a priority, and the gaps around pipes, wires, recessed lights, and attic hatches can add up to a hole the size of a small window. Heat rises and pushes hard against every opening it can find, which means your heating system is working against the house every cold month. The problem compounds over time - a home that was slightly leaky when it was built becomes significantly leakier as materials settle and shift.
Air sealing is the first step, but it works best when paired with proper insulation coverage. If your attic has thin or damaged insulation in addition to air leaks, combining the sealing work with attic insulation delivers the full benefit - sealing stops air movement, and insulation slows heat transfer through the ceiling itself.
If your gas or electric bill has crept up over the past few winters without any change in your habits, your attic is a likely cause. Norwich winters run long and cold - from November through March your heating system is working against every gap in the attic ceiling. Upstairs rooms that feel noticeably colder than the rest of the house are another signal that heat is escaping upward.
Ice dams are the ridges of ice that build up along your roofline after a snowfall. They form when heat leaking through your attic melts snow on the upper roof, and the water refreezes at the cold eave. Norwich gets enough snow and cold to make ice dams a recurring problem - and they are almost always a sign of air escaping through the attic floor. Left alone, they can force water under your shingles.
Hold your hand near your attic hatch, recessed lights, or ceiling fan housing on a cold day. If you feel cool air moving, that is a direct sign of a gap between your living space and the attic above. Many Norwich homes have attic hatches that were never properly weatherstripped, and they leak constantly throughout the heating season.
A large share of Norwich's housing stock was built before 1980, and most of those homes have never had their attics professionally assessed. If no one has ever looked at the attic floor for gaps and holes, there is a strong chance significant air leakage is happening. EnergizeCT offers low- or no-cost home energy assessments to eligible homeowners - it is a practical first step that gives you real information before you spend anything.
We seal every penetration in the attic floor - around pipes, wires, recessed light fixtures, the attic hatch, and anywhere else air moves between your living space and the attic above. We use the right material for each location: spray foam for irregular shapes and smaller gaps, rigid foam board for larger openings, and fire-rated caulk around anything near a heat source. A contractor who only seals the obvious spots is leaving the job half done. Our approach is systematic, working across the full attic floor so the result is measurable - not just a visual check that things look better. For homeowners who want to address the full picture, we also offer attic insulation as a companion service, and for homes where moisture is moving in from below as well, combining attic sealing with retrofit insulation throughout the home gives the most complete energy improvement.
Before any sealing work begins, we assess the attic to map the leak locations and check the condition of existing insulation. If insulation needs to be temporarily moved to reach the attic floor, we do that carefully and replace it when the sealing is complete. We also check attic ventilation during the assessment - sealing done properly keeps the attic floor airtight while leaving the attic itself properly ventilated through soffit and ridge vents, which is an important balance in Norwich's climate where river-valley humidity can be elevated.
Best for homes where heating costs are high and no prior sealing work has been done - addresses all penetrations across the attic floor systematically.
Suited to homes where the attic access door is a primary source of air leakage - often one of the most cost-effective single improvements in older Norwich homes.
Appropriate for homes with recessed ceiling lights below the attic, which are among the most common and significant air leak points in pre-2000 construction.
The right approach for homes with numerous utility penetrations through the attic floor - plumbing chases, electrical conduit, and HVAC runs that each carry air if left unsealed.
Norwich sits in eastern Connecticut, where January temperatures regularly drop into the low 20s Fahrenheit and the area receives meaningful snowfall each winter. That combination means an unsealed attic is under constant pressure from November through March - heat pushes upward and outward through every gap it can find, and snow on the roof becomes the raw material for ice dams. Norwich also sits at the confluence of the Yantic, Shetucket, and Thames rivers, and the surrounding area experiences elevated ambient humidity compared to inland Connecticut communities. When warm, moist indoor air escapes into a cold attic, it can condense on wood framing, causing mold growth and rot over time. Homeowners in Montville and Waterford face the same eastern Connecticut climate conditions and call us for attic sealing work every season.
The older housing stock in Norwich - particularly homes built before 1970 in neighborhoods across the city - means attic sealing jobs here often involve more penetrations and hidden leak points than newer construction. Connecticut requires home improvement contractors to hold a valid registration with the state Department of Consumer Protection, and the U.S. Department of Energy identifies attic air sealing as one of the most cost-effective improvements a homeowner can make, particularly in cold climates like eastern Connecticut. The EnergizeCT program - available to Norwich homeowners served by Eversource - offers rebates for qualifying air sealing work and helps offset the upfront cost of projects in older homes.
We will ask a few quick questions - your home's age, whether you have had an energy audit, and what is prompting you to call. This helps us estimate scope before we arrive. We respond to all inquiries within one business day, and we will flag available EnergizeCT rebates if your home qualifies.
We inspect the attic floor for leak locations, check the condition of existing insulation, and assess attic ventilation. Some jobs use a blower door test - a fan placed in your front door that pressurizes the house to measure exactly how much air is leaking. You receive a clear written estimate before any work begins.
The crew works inside the attic, sealing every pipe, wire, and light fixture penetration using foam, caulk, or rigid panels depending on the gap size and location. If existing insulation needs to be moved to reach the attic floor, we replace it when sealing is complete. Most jobs finish in a single day.
When the work is done, we walk you through what was sealed and clean the work area. If your project qualifies for EnergizeCT rebates, we handle the submission on your behalf. Some jobs include a post-sealing blower door measurement so you can see the improvement in numbers.

(959) 234-0488A large share of Norwich homes were built before 1970, and we work in them every week. That means we know where the hidden leak points are in older framing, how to navigate low-clearance attics, and how to seal around original construction details that newer homes never had. You are not paying for a crew learning on the job.
We are familiar with Connecticut's EnergizeCT program and can tell you upfront whether your project qualifies for rebates. We handle the paperwork on your behalf, so you do not have to figure out the program requirements on your own. Many Norwich homeowners recover a meaningful portion of their project cost through these rebates.
We use blower door testing to measure air leakage before and after the work, giving you a real number rather than a visual estimate. The Building Performance Institute sets the standard for this kind of measurement-based approach. Contractors who skip the test cannot tell you how much the work actually improved your home.
Connecticut requires anyone doing home improvement work - including insulation and air sealing - to hold a valid state Home Improvement Contractor registration. You can verify our registration through the Connecticut Department of Consumer Protection's online lookup tool before you sign anything. That registration also means we carry the insurance that protects you if anything goes wrong.
Every one of those points matters for a project like attic air sealing, where the quality of the work is not visible once insulation is replaced. We put the proof in writing - the estimate, the scope of work, the rebate paperwork, and when applicable, the before-and-after blower door numbers. You know what you paid for and you can verify it.
Add insulation to your existing attic, walls, or crawl space without tearing anything apart - a natural follow-up once attic air sealing is complete.
