Customers say: Super punctual

"We hired McLaughlin & Williams through the MassSave program, which had performed an energy saving audit for our house and made a clear checklist of work to be done that we could confirm with the contractors. We scheduled the job months in advance, but they were flexible when we needed to reschedule at relatively short notice. Jay and his team showed up early the first day, and clearly laid out the work they were going to do, and why. When weather and scheduling issues prevented work on the second day, they sent a double team on the third to make sure everything got done within the scheduled time. In general, the workers took good care. The exterior siding that was removed for injection was cleanly replaced, though some shingles that were already damaged or waterlogged were a little worse off. Despite all the dust that comes with blown cellulose, there were only a few traces inside. They also made sure our cats didn't get out. During the course of the job, they also found that there was already some wall insulation in one section of our house, and only charged us for the work done."

"Following a MassSave audit, about 6 months ago Hugh's insulated our garage. We were very pleased with their work. When we decided to do additional work and insulate our attic, I called Tom again to arrange for Hugh's to do the work. It went very well. I would definitely recommend them to others."

"I was plagued with recurring ice dams in a few areas of my roof. After investigation, it was discovered that the insulation in a few visible areas was sub-par. Roland came in and quickly spotted the problem areas. He assured me that the could fix these problems immediately. He used a combination of rearranging existing batts, blown-in fiberglass and spray foam to seal the attic space, over the course of two visits. He's extremely personable and always called me back or answered the phone right away."

"This is the second time I have used MA Design and Construction for a project in my house. Both times were great. For the most recent job, they framed up a partially finished basement, added carpet, leveled the ceiling, added a door and electrical outlets and insulated and painted the walls. The finished product looked great. I have found them super easy to work with - they are always very responsive to any questions that I have and they are great about communicating. I plan to have them do additional work for us in the future."

"I called these folks to get a quote on removing vermiculite from an attic. They were pleasant and prompt. They informed me about the Zonolite Attic Insulation Trust which can, provide significant reimbursement for the removal and took and sent in a sample to get tested to see if it qualified for reimbursement. All of this before I even got an estimate. When I asked them about some mold they were gracious enough to suggest I find a firm that could do both and suggested a contractor. In the end I didn't use these folks based on comparison quotes but based on their professionalism, honesty, and knowledge I'd highly recommend them to anybody that needs this kind of work."

"

We started by trying to find a contractor that could fix our gutters. We needed it to be done very quickly so I had called several people with no luck. Then I found United. Alessandro was amazing and his team is amazing -- especially Jackie. They are always very responsive, professional, dependable and of course their work is top notch/very high quality. They not only did our gutters when I needed them done, but also we went back to them to replace our sump pump, paint inside of most of our house, change the kitchen countertops and backsplash etc.. Alessandro also helped me find other specialists when needed such as shower door installers.. I am very happy that I found them and I will for sure go back to them again.

"I received an emergency call from my tenant that the apartment door would not lock. I checked Angie's list for a local handyman and called JR maintenance for assistance. They were busy with another another job 25 miles away, but went out of their way to diagnose the problem the following evening. Usually I would perform the work, but was out of state on business.

JR was punctual and actually repaired the problem without a service charge. They are now saved to my phone contacts for future work this coming year."

"We hired Matt to completely finish our once old and scary unfinished basement, something we had talked about doing for years but never thought possible given the age of the house (late 1800s) and unique challenges (dampness, field stone foundation, uneven concrete floor). The scope of work included adding a bathroom with shower, designing a family room including fireplace accent, creating a laundry area and storage areas, with built ins throughout. We have had a great experience with Matt. He has creative ideas on how to approach projects and is a perfectionist, which shows in his work. He has a great sense of design and will take the time to discuss recommendations and pros and cons of doing something a certain way. We have appreciated in particular Matt’s responsiveness. He is quick to respond by phone or text, even late in the evening and weekends. When we had a random issue with our HVAC system during a hot summer spell (completely unrelated to Matt’s work) and were not able to get home to find the problem, Matt went to our house in the evening to look at it. He even stopped at the Home Depot to buy a tool he needed to diagnose the issue. We were blown away that Matt went out of his way to do this, knowing it took him away from his family. There have been several times that Matt has gone above and beyond in this way. Matt also works with a top notch team of specialist sub-contractors (plumbers, electricians) who have done excellent work in line with the overall project. We wouldn’t hesitate to recommend Matt and are looking forward to working with him again!"

Insulation questions, answered by experts

In Boston, most attic insulation projects are completed within one to three days, while wall insulation often finishes in a single day. Basement or crawl space insulation may take two to four days, especially if addressing moisture or ventilation issues. Projects involving older or historic homes, or those requiring detailed energy audits, can extend timelines, so plan accordingly to avoid unexpected delays.

Helpful?

Boston homeowners often miss key steps like sealing air leaks before installing insulation or neglecting to check for moisture problems, which can reduce insulation effectiveness. Overlooking attic ventilation, ignoring the need for higher R-values in certain areas, or starting projects during peak weather seasons are also frequent mistakes. Careful site preparation and clear communication with your contractor help prevent these issues.

Helpful?

Before starting insulation service in Boston, schedule a professional energy assessment to identify specific needs, thoroughly vet insulation contractors, and confirm if permits or historic approvals are required. Prepare your home by clearing access to work areas and addressing any existing moisture concerns. Document current insulation conditions and plan your project timing to avoid peak seasons, ensuring a smoother and more efficient process.

Helpful?

When hiring insulation service professionals in Boston, prioritize contractors with proven experience in local housing styles and climate challenges. Look for proper licensing, insurance, and certifications in energy efficiency or spray foam insulation. Ask about their approach to moisture control, recommended R-values for the region, and whether they offer attic insulation or comprehensive air sealing as part of their services.

Helpful?

In Boston, you’ll encounter several contractor types for insulation service, including attic insulation experts, spray foam insulation specialists, weatherization contractors, and general contractors with insulation experience. Some focus on energy efficiency upgrades, while others handle historic home insulation or combine air sealing with insulation. Matching your project to the contractor’s specialty ensures you get the best results for your home’s unique needs.
