Could not be happier with our service from Koala Insulation. We had done an Energy Audit with another business (assigned to us) and weren't super thrilled with their service or recommendations to better insulate our attic. Emailed Koala; Graeme (the owner) returned my call within a couple hours, set up time to come out to our home, listened to our needs, executed a change order through EnergizeCT... the entire process was totally seamless. I wish every contractor had Graeme's communication skills! The team who installed our attic and crawl space insulation arrived as expected, worked quickly, and showed me pictures of the work when completed (I do not like going in my attic!). When we had one minor issue that needed adjusting (one recessed light was slightly crooked), they came back out quickly and fixed it. Graeme processed our rebate, which we received quickly. If you need insulation, don't hesitate to work with Koala. Highly recommend! Graeme & team - thanks for making this experience so easy.

The entire experience I had with Koala for my attic insulation was incredible. Started with getting a quote which happened very quickly after making the initial phone call. Scheduled the install date; I ended up needing to change the date due to another project happening in my home and they were so easy to work with and understanding! On the date of the install Tony and his partner showed up on time, got right to work, and did an amazing job insulating the attic. They explained everything to me in detail that they were going to be doing, updated me along the way, it really didn’t make any mess in the area they were working but still cleaned up leaving it cleaner than when they started, and were so kind and professional. Would highly recommend Koala. Thank you!

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!!

Written by my mother who recently had work done on her house: "I highly recommend HCP! The crew were knowledgeable, and professional from audit to completion of project. They answer any & all questions or concerns. They cleaned all areas worked on leaving my home pristine daily. Customer Service is OUTSTANDING, especially Lucy B. who was so informative & friendly. So impressed with this company, they not only did my insulation but replace my windows as well! Thank you so much Mr. Wyatt for helping me make my home energy - efficient!!!"

Vanessa Wisdom★★★★★2 years ago

USA insulation did a wonderful job on my Condo with insulated of the entire unit… Dominik Doel and his coworker worked efficiently and very professionally trained in what they had to do… Most definitely will refer to my friends here in my Complex… Thank you..

The whole team at USA Insulation of CT was great to work with. Karissa was diligent about keeping me aware of things via phone and text, Matt did a fantastic job of determining our insulation needs and walking us through the process, and Benny and his team (Dominick, Julio, Joey, and Darian) were extremely efficient in getting the job done properly. Seriously, I work from home and it was like they weren't there at all! They got to my place right on time, set things up, got to work, and cleaned up so well after they left the place nicer than they found it! Of course, along with fantastic customer service, the insulation has already begun to pay off. Our new home had only about 5 inches of insulation in the attic (yikes) and barely any insulation at all in most of the walls (double yikes!). How the previous owners managed to survive living like this is beyond me. We realized we needed to check our insulation more thoroughly after the ac was struggling to keep our second (and main) floor below 82 degrees. We're able to track and monitor when our ac cycles on and off. Since installing the insulation just yesterday, there's already been a noticeable dip in the amount of times the ac has had to cycle on. Even now, it's 90 degrees outside while inside it's a comfortable 72 degrees. And the last time my ac had to cycle on to keep it there was... an hour ago for about 15 minutes. That is a MASSIVE improvement. So to USA Insulation of CT, you have our sincerest thanks for making our first house feel like that much more of a properly comfy (and cool) home!

Workers arrived at scheduled time and did an outstanding job. Answered any questions and concerns before starting. They proceeded to perform their work and finished efficiently. Did some extra clean up when finished and gave a thorough walk-through to explain their work. Everything was done to great satisfaction

I just worked with Dr Energy Saver to get insulation installed in my house. I would absolutely recommend them to any friends or family. From the beginning of the process through the final inspection, this company was a pleasure to work with. I would like to especially thank Keith Saunders and Johnny Lopez. Keith was beyond helpful while simply conduction the inspection and developing a quote. He really helped get me a service that was within my budget. Come installation day, Johnny was incredibly respectful and a pleasure to work with. Johnny ensured that everything was done right and the house was spotless after. Again I will absolutely be recommending this company to my friends and family.

Amy Shane★★★★★5 years ago

I called Dr. Energy Saver because I had extensive mold in my attic. They did a fantastic job removing the mold, sealing air leaks and Re-insulating the attic.The upstairs is so much warmer now. They also did a great job insulating our rim joist in the basement, replaced the basement door and insulated a downstairs room. The crew was friendly, on time and cleaned up their area every day.

Gordon Bishop★★★★6 years ago

In Dec. 2019, I had extensive work done on my attic - air sealing, installing new insulation, a new catwalk, an insulation box over my attic ladder, improving the duct work from my bathroom fans. They did an excellent job and were pleasant to deal with. They responded promptly to my concerns subsequent to finishing the job. My only reservation was their price - $10,000 which I thought was high. but I proceeded anyway because I had confidence that they would do the job right.

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!!

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.

Frequently Asked Questions — Spray Foam Insulation in Hartford

These are the questions Hartford 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 9 verified Hartford contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Hartford?▼
Homeowners in mixed climates like Hartford, 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 Hartford?▼
For most homes in Hartford, 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 Hartford, CT?▼
In Hartford, 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 Hartford costs $2,000–$6,000. Most Hartford 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 Hartford, CT?▼
When searching for a spray foam contractor in Hartford, 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 Hartford 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 Hartford 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.
