Elite lives up to their name. The owner Troy is honest fast and reliable. From the moment I spoke with Troy, I knew that I had the guy for the job. In less than 72 hours I had a beautiful new roof. Right after I had the house powerwashed and the washer dislodged something. Troy came out personally the next day and repaired it at no extra cost. Great guy! Highly recommend.

I can't say enough wonderful things about Troy and his team. Troy is extremely responsive and willing to answer any questions you might have.

I HIGHLY recommend Troy and his team to anyone looking for a new roof!

Josh Landau★★★★★6 years ago

Jario and his team did a great job! We were looking to spray the inside of our metal auto garage so we can detail cars throughout the winter. After getting several quotes from different companies, Sono was priced the fairest. They were efficient, timely, and did a great job cleaning up. Very satisfied with their work. Definitely recommend! B and L Auto Sales thanks you!

Bill★★★★★3 months ago

After being disappointed by a previous spray foam installer that I had worked with to find they were no longer servicing my area. I searched on-line and found Sono Spray Foam. I called and spoke with Jairo Urena, the owner of Sono Spray Foam. He was immediately responsive and came to look at my job (same day within hours), which was not a huge job but was important to me and it needed to get done. Jairo gave me a reasonable price and told me he could do the job the next day. The next day he and his guys showed up as promised. They took great care to protect my home before they did any work. They did a great job applying the foam insulation as we had discussed. They left my home clean and did a great job. I will definitely reach out to them again if I need more work done. Call them, hopefully you will have a great experience like I did. Thanks Jairo!

Good Life Energy Savers is a professional and personable bunch of people who get the job done, and done right. We had an energy assessment recently, and they did some vent and doorway sealing for us. The work was done well, and we've noticed a difference already. We have a cat and also WFH, and the guys were super respectful of our time and space. Dom & Dave are fabulous! Highly recommend.

ankush gupta★★★★★3 months ago

Highest recommendation!! I had David from the company for home energy assessment. Him with another crew member did a very good job detailing out the condition as well as dealing with a lot of air leakage paths. I got a quote from them for the attic insulation update. They made it very clear that I dont have to opt for services from them and can opt for any licensed contractor to be eligible for the rebate from the state. I got quotes from other contractors which made it amply clear that their pricing is very competitive. Juan and the crew came and did the attic insulation work. Excellent work. Hugely satisfied.

Richie Dambra★★★★★a year ago

Great insulation contractor with very friendly and professional staff. Our service started with an energy audit through the EnergizeCT program, and the auditors did a very thorough job helping to air seal the house and ductwork. We then contracted basement and attic insulation installation including blown cellulose, rockwool and fiberglass batts, and spray foam for the rim joists. The sales coordinator, Tom, was helpful and a timely communicator. Finally, we were very happy with the highly professional job that Juan and Bill completed at our home. These guys are pros at their craft and exhibited a high attention to detail which is helpful to get the absolute highest energy efficiency possible. Beyond that, the staff was very courteous and took care during their job to treat our home and belongings with respect. Very friendly guys as well, I enjoyed talking with them. My family and I are really grateful after working with this company and give them the highest recommendation.

As a homeowner in the process of obtaining a certificate of occupancy for my property, I encountered a significant hurdle in acquiring a crucial document from your company as the job was done several years prior. I reached out to your team, and from the very beginning, the level of professionalism and dedication demonstrated by each member was truly remarkable. Your team went above and beyond to assist me, guiding me through the necessary steps and promptly providing the document I needed to move forward with the certification process. Not only was the service efficient, but it was also delivered with a genuine sense of care and understanding, making what could have been a stressful situation remarkably smooth and manageable. I will not hesitate to recommend your services to anyone in need, and I look forward to the opportunity to work with your team again in the future.

LAYCOS★★★★★5 years ago

I know Antonio since he was just starting business many years ago , and I can't complain at all Pros :all my projects were completed with no problems , 100% of then pass inspection and never had problems with damage equipment during installation ( a common problem with insulation companies) can't complain on price as well always had a fear price . Cons : some minor things like maintaining a better communication during a project and a little more presentation on the trucks ( cleaning and stuff ) Overall I will keep continue hiring Antonio for my projects , I had a couple trys with some new insulation companies in the ct area ( got a better offer ) but at the end I realize the material they use were cheap and theres no compromise taking care my stuff on the job .

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 Stamford

How much can spray foam insulation save on heating and cooling bills in Stamford?
Homeowners in mixed climates like Stamford, 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 Stamford?
For most homes in Stamford, 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?
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. 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 costs $2,000–$6,000. Most 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?
Look for contractors 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 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 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.
