Get matched with top insulation install or upgrade pros in Tewksbury, MA

"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. This was done through the Mass Save program. So the $2100 job only cost me about $500.00"

"Professional crew; work was done quickly, with minimal disruption and fairly good cleanup. The house is older and the crew chief took reviewed the interior carefully to insure there would be no damage to the walls in the insulation process."

"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

"HomeWorks Energy provided my standard MassSave assessment, and a scheduled heating/cooling assessment.Based on their work, I do not think it was worth my time. For the MassSave assessment, their only work was to change one lightbulb in our kitchen and leave two (useless) "smart" power strips that we won't use, since we don't have a TV or stereo.They did recommend some minor insulation, which we are planning to do ourselves, because even with the 70% discount from MassSave it is $1000 less expensive than their cost. Also, as a warning, their recommendations only bring up insulation levels to current building code. Energy saving standard-of-practice generally recommend much more attic and basement insulation than HomeWorks can recommend or offer discounts on.Finally, and this is what prompted me to write this review, I scheduled an additional heating and cooling assessment, as my initial MassSave inspector wasn't knowledgeable in those areas and didn't have any suggestions to offer. Instead of the inspector showing up, though, I got a phone call 10 minutes before our scheduled time, claiming that they didn't recommend their team coming out to the property because 1). the previous inspector saw a few pieces of fiberglass (personally installed and then removed by me when it melted) adhered to a radiator pipe, and they needed an asbestos abatement company to sign off on it before they could do any work, and 2). because I wasn't yet eligible for a particular rebate, they didn't think it was worth their time.Given that I wanted to talk about future installation options to budget and plan for, I found this deeply unprofessional, not to mention ridiciously red-tape laden. I would NOT recommend HomeWorks Energy for any work or assessments in the future."
