An uninsulated crawl space is one of the biggest sources of floor-level cold and energy loss in eastern Connecticut homes.

Older Norwich homes often have empty wall cavities. Wall insulation stops drafts cold and quiets street noise at the same time.

Insulation slows heat - air sealing stops it. Sealing gaps around pipes, outlets, and framing is what makes insulation actually work.

A cold, damp basement pulls heat from your whole house. Insulating basement walls and the rim joist makes a fast, noticeable difference.

Closed-cell foam has the highest R-value per inch and acts as a moisture barrier - the right choice for crawl spaces and basements.

Open-cell foam fills attic cavities and interior walls, providing solid sound dampening alongside a strong thermal barrier.

Eastern Connecticut's damp climate makes crawl space moisture a real risk. A vapor barrier keeps ground moisture from entering your home.
Learn More
Moisture in walls and crawl spaces leads to mold and rot. A properly installed vapor barrier cuts that risk before it becomes a repair bill.

Attic air sealing stops warm air from leaking into your attic before insulation goes in - it is the step most contractors skip.

Already have insulation but still paying too much to heat your home? Retrofit insulation adds performance without tearing out finished walls.
Learn MoreWhen you reach out, we ask a few basic questions about your home and what you have been noticing - high bills, cold rooms, drafts. No pressure. We just want enough information to give you a useful estimate when we come out, not a wild guess over the phone. We respond within 1 business day.
A contractor visits your home and looks at the areas you want insulated - attic, crawl space, basement, walls, or all of the above. We check what is already there, note any moisture issues, and measure the space. You get a clear explanation of what we found and a written quote before we leave.
Once you decide to move forward, we handle scheduling and any required permits. On installation day, we complete the work, clean up, and walk you through exactly what was done. Most homeowners notice the difference in comfort within the first cold snap after the job is finished.
We are registered with the Connecticut Department of Consumer Protection as a licensed home improvement contractor. Every job we take includes liability insurance - protecting you and your property from start to finish.
We never quote a job without seeing it first. Your free estimate includes a full walkthrough of the work area, a written breakdown of costs, and an honest recommendation - no pressure to decide on the spot.
We have worked on homes across eastern Connecticut for years and know the local housing stock well - older wood-frame construction, crawl spaces, and the moisture conditions that come with the region.
Before we leave any job, we walk you through the finished work so you can see it yourself. No mystery work, no wondering whether the insulation is actually there. You see the coverage and ask questions before we drive away.

"We had spray foam installed in our crawl space in early November. By Thanksgiving, the floors were noticeably warmer and the smell of dampness in the basement was gone. The crew finished in one day and left the space cleaner than they found it."
Daniel R., Norwich - Spray Foam Insulation
"My attic had almost nothing in it - just some old fiberglass that had been there for decades. After blown-in insulation was added, the upstairs bedroom that was always freezing finally feels like part of the house. The difference was clear after the first cold week."
Maria S., Groton - Blown-In Insulation
"I asked a lot of questions before the job because I wanted to understand what I was paying for. They walked me through every step during the estimate and again after the work was done. It was clear they knew what they were doing with older homes."
Kevin T., Waterford - Attic Insulation

The U.S. Department of Energy places Connecticut in Climate Zone 5, which calls for attic insulation between R-49 and R-60 - roughly 14 to 18 inches of blown-in material. Homes built before 1980 rarely meet that standard. The gap between what you have and what you need is where your heating money goes every winter.
If your home has gaps around pipes, electrical outlets, or ceiling penetrations, adding more insulation on top of them solves only half the problem. Air moves through those gaps regardless of insulation thickness. Air sealing those openings first - before insulation goes in - is what makes the insulation work the way it is supposed to.
Norwich sits near the Shetucket and Thames rivers, and many crawl spaces in the area accumulate moisture from ground contact and humid air. Standard batt insulation installed in a damp crawl space traps that moisture and leads to mold or wood rot. Closed-cell spray foam or a vapor barrier addresses both the insulation and moisture problem at the same time.
A large share of Norwich homes were built before 1940, with irregular framing, old wiring remnants, and original plaster walls. These features make insulation trickier - but also mean the home is losing far more heat than a newer build. A contractor who knows older construction will check for these conditions before recommending an approach. The U.S. Department of Energy's Energy Saver resource covers insulation options for older construction.
Open-cell foam is softer, less expensive, and works well in interior walls and attics where moisture is not a concern. Closed-cell foam is denser, has a higher R-value per inch, and acts as a moisture barrier - the right choice for crawl spaces, basement walls, and anywhere water intrusion is possible. Choosing the wrong type for the location can create moisture problems that outlast the insulation itself.
Insulation can be installed any time of year - there is no seasonal restriction on most jobs. That said, scheduling before the heating season starts gives you the full winter to benefit from the upgrade. Contractors in Connecticut also tend to be less booked in late summer and early fall, which can mean faster scheduling and more flexibility. Learn more about rebate timing at Energize CT.

If your existing insulation is wet, moldy, or shows signs of pest activity, adding new material on top traps the problem underneath. A contractor will tell you honestly which situation you are in during the estimate. The Building Science Corporation has useful guidance on diagnosing insulation problems in older homes. Building Science Corporation covers insulation diagnostics in depth.
Insulating a damp crawl space or basement without addressing the source of moisture first can trap water and create conditions for mold or wood rot. The fix costs more than the original insulation would have. A contractor who knows eastern Connecticut conditions will check for moisture before recommending an approach.
Go up into your attic and look at the floor joists - the wooden boards that form the attic floor structure. If you can see the tops of the joists poking above the insulation, you do not have enough. The joists should be buried by several inches. This quick check takes two minutes and tells you immediately whether an upgrade is warranted.

Norwich Insulation is based in Norwich, CT, a city of around 40,000 people at the junction of the Shetucket, Yantic, and Thames rivers. Norwich has a long history and a housing stock to match - a large share of homes here were built before 1940, many with wood-frame construction, original plaster walls, and foundations that have been settling for generations. That means insulation is not a straightforward job. We understand the local building stock because we work in it every week.
The city includes distinct neighborhoods - from the historic homes surrounding the Norwichtown Green, to the open space around Chelsea Parade, to the residential streets further out from downtown. We have insulated homes across all of these areas. Eastern Connecticut winters, with their regular freeze-thaw cycles and the moisture that comes from the rivers and damp soil, make proper insulation a higher priority here than in many other parts of the country.
Low-lying areas near the water - particularly around the Chelsea waterfront - have a documented history of basement moisture and flooding risk, as reported by the Norwich Bulletin. For homeowners in those areas, addressing crawl space and basement insulation alongside moisture barriers is often the most practical starting point. And for anyone across Norwich looking to reduce heating costs in an older home, census data confirms that Norwich households carry a higher energy burden than the state average - which makes a well-executed insulation upgrade one of the highest-return improvements available to local homeowners. We are here to help you make that happen.
