"Contacted McLaughlin for a quote and Bill Sovie from the company arranged to see the job for an estimate. Had to reschedule a couple of times due to weather etc, but when he got to the house he took measurements and let me know the approximate cost. He followed up a couple of days later with a written estimate, and their price was slightly less (but not substantially) than another quote I got. I asked them to get me on the schedule, and was told the office would contact me shortly. Within a day or so the office called and said they had a cancellation and could start the same week. I wasn't ready so I asked them for an alternate date which they had a week later. I scheduled the service, and they showed up when they said they would. The guys that came gave me a rundown on the job, told me I needed to be out of the house for 24 hours. They taped off the outlets, sealed all the windows etc and did a great job prepping the room. I wish they would have vacuumed out the foundation to get the 30 years of debris out, but I ended up doing it while they were prepping the room. They completely filled the bays with closed cell foam and did a great job. I had foam done a few years back with a different company, and MClaughlin's job was WAY better and more professionally done. The pictures I attached is while they were still cleaning up the job. I am super happy with their job and I would definitely hire them on my next foam insulation job."

"William the owner and his son, Gabriel are committed to finish the job with customer satisfaction and I commend them for their integrity. Unfortunately the spray technician is not skilled at applying the spray foam and the job needed 5 applications to even get close to what was promised on the contract. Bottom line, Greenway is a reasonable value if you?re willing to check their work and have the time to be perseveringly persistent and patient until the project is completed, but don?t expect the high, industry standards"

"We had a leak in our roof that for years I'd been trying to figure out from where it was coming. Water is tricky because where you're seeing it doesn't mean that's the source ("water finds a way"). Finally decided to call in an expert and Adam Vaillancourt Roofing was the first company that was listed in a Google search. The first thing I noticed was the company's consistently high customer satisfaction results (at least 4.5 stars). Customer service is very important to me when doing any work to our home, which is our biggest investment. I called and spoke with Cat Vaillancourt to set up an appointment. We met with sales rep Jose Luna, who conducted a thorough inspection and found the leak easily. His presentation about the company and how they do their work was impressive and Jose was very professional. The meeting included a video that Jose shot while on our roof in which he explained not just the issues that were found but WHY the work was needed. He patiently answered all our questions and never pressured us into agreeing to anything. It's our money, it's our decision, he said. After meeting with Jose, we didn't hesitate to sign a contract immediately to get the work done. One of the biggest factors in signing was that the folks who do the work are company employees, not contractors. Fast forward a few weeks later and Paul Camarro and his crew showed up at the house on time and ready to work. When they were done, Paul showed us photos of the completed repair work, so I knew they delivered as promised. Jose is in the process of making a follow-up appointment so that he can inspect the job and make sure that we are completely satisfied. From Cat Vaillancourt and Mary Kay Macfarlane in the office to Jose to Paul, every person we dealt with at Vaillancourt was fantastic and professional. Their emails often include the signature, "The Team at Vaillancourt Roofing" and it's obvious that they truly are a team. We will absolutely be calling Vaillancourt in a few years when our roof needs to be replaced. Highly recommend!"

"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

"I have done a lot of research into soundproofing and had a quite a few contractors stop by for an evaluation and a quote over the past couple years, and Robert stood out with his friendly demeanor, level of knowledge, and being easy to talk to; he seemed to have good experience in soundproofing and actually knew soundproofing concepts I'd read up on earlier (surprisingly many other drywall contractors were either evasive in rating their confidence in their proposed projects or simply did not have good plans or knowledge of options). He worked with me on a plan to redo a wall separating my bedroom from noisy neighbors, and the result is excellent! Robert and his team have turned a single stud wall into a decoupled double stud wall, with all the right elements for soundproofing, such as quality insulation, acoustic caulk and dampening compound (both by Green Glue), socket putty, etc. Robert's choice of materials was well informed, and the quality of his work was very good, neat, and precise. I could tell he enjoys doing his work well. He cleaned up after the job was done, and the new wall was perfectly plastered--all I had left to do was to paint (which I enjoy doing myself). The total expense was very reasonable for the cost of materials and labor. I also appreciated that Robert always kept me up-to-date on his schedule and coordinated his visits--great communication. Overall, I am extremely pleased with the experience and glad that I found Robert and his team! I can heartily recommend his services for your drywall and related projects! I'd like to also note for general reference that soundproofing is a global project: learn the weak areas where the sound travels--it's frequently not just your walls, but also through your floors and through your ceilings, including from neighbors on the same floor as you! You may think that just fixing one area will solve everything, but sound wave propagation needs to be considered from all directions/sources, and week areas need to be identified: e.g. you may need to redo your wall and your floor, for example, or your wall and your ceiling, or all 3 at once, depending on your exact needs and situation."

FAQs for spray foam insulation projects in Boston, MA

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
