I never thought I would feel so moved to leave a review about an insulation company but Home Comfort Practice was so wonderful to work with. Joe came out to create a plan of what we needed to do to improve insulation in our home and then took time to answer all my questions and concerns. The crew Juan, Alvaro and Gio were awesome, they took precautions to contain any mess and were great at communicating along the way, they take pride in their work and are super dedicated. I spent a lot of time comparing and deciding which company to choose and I'm very happy with my choice. Thank you guys!!

Starting with Gene in sales, through Jason in installation and the teams that supported them we are very pleased. We build a new house and their coordination, flexibility and installation of foam, battens and blow-in was outstanding. Thank you Quality.

Adam Mercer★★★★★9 months ago

This is my first time getting spray foam insulation. From the minute I connected with this company, every person from beginning to end made it worth writing a review for. The price was great. The scheduling was clear and prompt. The work looks great, and saved me a TON of time to do it myself. I absolutely recommend Kevin and his team at Quality Insulation.

Amazing little receiver. Staff was very friendly, and they had moved their box trucks out of the docks before my arrival to make docking easier. Make a uturn into the parking lot so you can blindside angle back down the hill with your tandems about 3/4 to the rear. I was put into 2nd dock and there's enough room to maneuver

Yiska Batsarai★★★★★6 years ago

I contacted Ecologic Energy Solutions to have my old attic insulated. Sales rep Richard came out the very next day to give me an estimate which was better than I had anticipated. He was very knowledgeable about updating and suggested I foam the attic roof AND walls. I had gotten other prices from other companies but they were $500-1000 more for the same job. Even better, Richard saw the project out from beginning to end, and the crew that came did an amazing job and left my attic spotless. What more can I say? As I continue to update my house, I will definitely use Ecologic in the future for my insulation needs.

Bob Janson★★★★★8 years ago

I used Ecologic for spray foam in my addition in this past fall. Of the three companies I contacted, they were the most responsive, knowledgeable and also competitively priced. Their workers were efficient, neat and it was clear they took pride in their work. I'd recommend them to anybody looking for a good insulator, really top notch.

Lennox Somers★★★★★5 years ago

Had ecologic come out to do the spray foam work in my attic and basement that we decided to finish. They were amazing and the quality of their work was very impressive. I had a different company do work two years ago on a different area in my house, and was not happy with the final product. Was unsure if I wanted to use foam again, but Rich assured me that I was in good hands with his team. The Crew that came out was very thorough and meticulous. not only was the workmanship excellent, but they left the place Spotless upon completion. I cant recommend these guys Enough!!! Thanks Guys!!

Frequently Asked Questions — Spray Foam Insulation in Norwich

These are the questions Norwich homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 4 verified Norwich contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Norwich?▼
Homeowners in mixed climates like Norwich, CT typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Norwich?▼
For most homes in Norwich, CT, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Norwich, CT?▼
In Norwich, CT and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Norwich costs $2,000–$6,000. Most Norwich homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Norwich, CT?▼
When searching for a spray foam contractor in Norwich, CT, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Norwich contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Norwich for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
