Nate is very professional and knowledgeable. He was able to meet with the General Contractor and myself prior to spraying. He was able to answer all questions and provide appropriate suggestions on how the complete the job. He showed up on time and completed the job in the expected timeline. He and his crew appropriately covered the surrounding environment to keep the foam contained and did an awesome job cleaning up. He was able to provide photos of all of his work for documentation. We found several areas of our house that needed additional insulation (that we're not part of the original area) and he was able to come back and quickly fill those areas.

I cannot say enough good about this foam insulation company. These guys came out to my residence and did an addition that we are adding to our home. They were very respectful, competent and timely whether it be face-to-face or when I emailed asking different questions. Price was very reasonable. Don’t waste your time with anyone else.

THOMAS LEE★★★★★4 years ago

Built myself a steel garage. Wanted 1" of closed cell foam through out. The larger players in the game tried up selling me 2"or 3" and time frames over a month out. Along comes Spray Right Foam. Nate, very knowledgeable and professional, quoted me the 1" I wanted and was available the next week. Just a happy customer with no affiliation with these folks. Check them out. Pictures speak a thousand words.

Insul-Kings came out And evaluated my home for insulation. They helped enroll us into Mass Save program Which paid for 100% of the work for my 2 family home. The entire process took about a month, but they were able to get the work done in a few days. Have turning your head on we have definitely noticed a difference in our home. I highly recommend this company

John Ricciuti★★★★★3 weeks ago

Insul-Kings is wonderful to work with. They called in the morning to narrow the arrival time, which is very considerate. Nate and his crew arrived on time and CRANKED like a well oiled machine. I have a 4' crawl space. You can barely crouch. No problem! That's why God invented knee pads. They foamed and installed the insulation like it was their own home. It was a work of art. and came out better than I imagined. They patiently indulged my "old man" inquisitiveness. The crew represented Insul-Kings very well. I highly recommend them

Dennis Sitkowski★★★★★a month ago

We highly recommend Insul- Kings. We had an issue WITH ANOTHER COMPANY who installed our closed cell insulation in our attic. Chaz went above and beyond to answer a myriad of questions about the issues we had. He was kind,caring and knowledgeable. He provided critical safety information regarding the rework that the other company did not. We only wish we had hired Insul-Kings for the original installation.

I have been doing business with Star Insulation for over five years and I’m always more than satisfied with their quality of work. Star insulation is my go-to company when I need insukators.

Jason Byrne★★★★★2 years ago

I am ecstatic with the work done at my home by Star Insulation. I had gutted a 12x12 addition in my home back to the studs and found virtually no insulation anywhere. Star came out and gave me an estimate on Closed Cell Spray Foam Insulation and got me a price quickly and even was willing to work that price down to match a competitor I had quote the same work. Their scheduling process was quick and simple and even better yet, one of their foremen came back the following morning to make sure things were good and was happy to spot spray a couple areas that were a bit thinner than the rest near my windows and door framing. Room feels like a completely different space temperature and air wise. I am already planning to give them a call when I am ready to redo my finished basement. Thank you to the Star Team that helped us on our project.

Absolutely amazing clean work. Had dozens of holes on my exterior walls and they made them disappear. Didn’t have to repaint the entire wall and matched multiple different colors to make it look like the wall wasn’t even touched. Would absolutely recommend

Peter Carty★★★★★4 weeks ago

This is the third project Master Plastering has done for us. Fast, efficient, fairly-priced work. Reliable, on-time. Good clean-up. Professional communications. We would not hesitate to hire them again for plastering and paint work.

Joey Terranova★★★★★a year ago

We had Erick and Best Pro Builders reach out to us from a home advisor site to fix our kitchen that suffered some water damage. His quote was competitive and reasonable for the work I had requested. We had bought the new lights to install and his electrician installed everything perfectly, even going so far as to correct a hidden junction box that was found during the demolition for no extra charge! His employees were super friendly, worked diligently, and were respectful. They even removed the language barrier by using translator apps so that we could freely communicate and convey pertinent information to each other. Erick's communication was great, we were never left wondering what was the next step. He collected his deposit when the work started and the remainder when the work was done. I really, earnestly cannot say more, other than that we plan on calling him back for future work!

Mike and his guys did a fantastic job with our gutter install on our new home! When we requested a slight adjustment, they returned no problem to adjust. Communication, price, and customer service were all stellar - highly recommend!

Dave Maloof★★★★★2 years ago

Out of the 6 quotes I got for spray foam, these guys were the only ones to actually make recommendations of how to get a better final product. Even after we agreed to add a few more things on than the other quotes, they were still very competitive. They took the time to do the job to the best of their abilities like it was their own house, and were very friendly and courteous through the whole process. We had a second floor and basement rim joist spray foamed and the end result looks awesome. They did a great job cleaning up after themselves too. Would absolutely recommend them to anyone

aram manoukian★★★★★a year ago

Great so far. They just finished up, and couldn't have been more polite throughout the job. They were patient when I asked questions, and they checked in with me frequently if they figured I'd like to know about something. They also did a great job cleaning up as they were leaving each day.

I chose The Green Cocoon based on their strong reputation. Our job wasn’t the simplest, and when complications came up, they did a great job following through and making sure any challenges were addressed and corrected where needed.

I HIGHLY recommend! I had a wonderful experience with Green Way Insulation. Gabriel was professional, personable, knowledgeable and so easy to talk with. The installers were professional and efficient who deserve huge kudos for working on two of the hottest days of the summer. After having a horrible experience with another installer, Gabe and the team came to the rescue! Professional service, excellent work and very fair pricing. Thank you for being awesome!

Frequently Asked Questions — Spray Foam Insulation in Lowell

How much can spray foam insulation save on heating and cooling bills in Lowell?
Homeowners in mixed climates like Lowell, MA 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 Lowell?
For most homes in Lowell, MA, 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.
