Prospective Energy Solutions does insulation and air-sealing work. The company says it has been in business for 20 years, and the Better Business Bureau gives it an A+ grade. A 2026 customer said that over four days, Scott and his crew sealed the crevices between the attic joists and sheetrock of a 3,500 sq ft, 60-year-old house, blew in 18 inches of insulation and sealed each basement bay with rigid foam board and spray foam. That 2026 customer said the final testing at the end of the job revealed a malfunctioning furnace damper that had been allowing carbon monoxide into the house. A recent customer said Scott and his team did an initial assessment and found areas in need of attention that others had never identified, and that the RISE program through Mass Save covered all the cost of the work. A recent customer said Scott insulated a really narrow crawlspace and asked MassSave to add another step to the job to increase the R factor efficiency. That customer said the company can do work anywhere in Western MA. A 2026 customer who expected only attic insulation said they also took off small areas of siding, drilled a hole and pumped in cellulose where the old insulation had shifted. A 2024 customer said Scott McCray and his crew cleaned out old insulation and mouse droppings, installed a hatch in a hall ceiling to reach a hard-to-access part of the attic, found a leaking chimney there and left 15 inches of cellulose throughout the attic. A 2025 customer said the work was put off for a few months when bats were found in the attic, and that the crew worked within that customer's schedule.
This is absolutely the best insulation job I could have imagined. Scott and his team were extremely thorough, transparent, professional, and helpful. They performed an initial, assessment, and found area areas In need of attention that others had never identified. I feel for the first time that my house is fully and appropriately insulated and I’m ready for winter.The RISE program covered all the cost of the work. I highly recommend this state program through MASS SAVE. I cannot thank Scott and his team enough. I recommend them without reservation to anyone seeking the best insulation job done for their house.
So happy with the services of this company. Thank you to Scott for insulating a really narrow crawlspace and fingers crossed when winter comes again we are able to enjoy our living room. The whole crew were kind, respectful, and professional. They come on time and Scott talked to me about the scope of the work order. I discussed the temperature in our living room and he advocated with MassSave to add another step to the job to increase the R factor efficiency. They automatically kept the front door closed b/c we have a indoor cat. They vacuumed the hall and outside around the doors to make sure that they didn't leave any mess. This company can do work anywhere in Western MA and I really hope to use their services myself again in the future to keep our home warm. So nice to met you Scott, Diego and Zach (and one other gentleman that I didn't get to meet).
Scott and his crew did an excellent job sealing up our entire 3,500 sq ft, 60 year-old, house. Over the course of four days, they painstakingly sealed every crevice between the attic joists and sheetrock, added channels to force the outside air to circulate properly into the attic, and blew in 18"of insulation. They also sealed each bay in the basement with rigid foam board and spray foam insulation. The absence of cold spots, drafts, and cold radiating from the ceiling was noticeable on the very first day of the job. It has now been four days since they finished and the improvement is incredible. The furnace is only running a fraction of the time and, as of this morning, we were so cozy inside that we had no idea how cold it was outside. They also installed a fresh air ventilation system and ventilation for our kitchen hood vent. Most importantly, their final testing inspection at the end of the job revealed that we have a malfunctioning furnace damper that has been allowing carbon monoxide to seep into our home. They caught something the hvac pros have missed every year and saved us from a potential tragedy. We can't speak highly enough!
Our home was made toasty warm by experienced, competent professionals. So much more was done than we expected. I thought they would just insulate our attic. They also took off small areas of our siding, drilled a hole, and pumped in cellulose to fill in the cold spots, where the old insulation had shifted. An insulated basement door was added in front of the bulkhead. This raised the temperature of our basement by several degrees. They also insulated the perimeter of the basement sill plate. They installed a new bathroom fan and enclosed the venting of two fans. They did a test before and after to see how tight the house had become. I don’t recall the exact figures, but it went from around 2200 to 1400? The lower, the better. They were all wonderful and even vacuumed up the insulation. This company is A1 and I am 100% happy with the process and results.
Amazing work done by these folks! Very communicative, efficient and clean work. Scott and his team did an amazing job and Scott kept us informed throughout the whole process. Highly recommend these folks to anyone that wants to be warm without braking the bank.
