They did our Mass Save insulation and were efficient, professional and courteous to us and our home and super helpful with tips that we as homeowners could do ourselves. Definitely will use them again in the future as we update our home. Thanks for the great work!!

Connected with Green Collar through Angi. Very responsive, scheduled an appointment that evening…read morevia text message. Today was the day of the appointment, and the tech did not show. I messaged the same person that booked the appointment, and first they said there was a mix up and the appointment wasn't scheduled, and then they stated that the job was cancelled because the scope was not something they supported. No call to follow up on the cancellation, no messages. I had to take time off work to be here for the appointment, and I had to call to find out where the tech was and what happened to the appointment. Scheduling is one of the most basic expectations of a company that provides services like these, and this experience was horrible. Get your act together and stop wasting my time.

Our questions went completely unanswered, and they capped off the visit with an absurd $18,000 quote for air sealing. Their participation in Mass Save borders on a scam. If you're scheduling an audit, I recommend contacting Mass Save directly to request a different vendor.

NEGATIVE 1,000 STARS…read more I hired HomeWorks Energy for attic insulation through Mass Save. I paid nearly $3,000 out of pocket -- while HomeWorks reportedly billed the state program roughly $16,000 for the same job. Draw your own conclusions about where that gap goes. The crew did not properly seal or protect the area they used to access my attic. While spraying insulation foam, they let a can explode, coating a leather messenger bag that my late father gave me shortly before he passed away. It's now ruined -- foam soaked into the leather and fabric strap, and no amount of cleaning has restored it. On top of that, one of the crew members' behavior raised serious safety concerns. He spent much of the appointment with his face covered, sitting in his running vehicle, and locked in my bathroom. He repeatedly drank Gatorade and had to lean against the truck to steady himself. He then bolted out of the house and ran head-first at full speed toward the HomeWorks truck parked on my street, nearly colliding with it. I'm not sure if he had a hard night out before visiting my home that morning, but he never should have been dispatched to a customer's home in that condition, with my family present. When I raised the damage to my father's bag, HomeWorks' "resolution" was to offer me the value of a refurbished/used bag from an outlet -- not a new one, despite this being a gift I received brand new. I've asked for a full refund of my co-pay, retail replacement value, and a formal apology. I have also repeatedly asked -- by email and by phone, on multiple occasions -- to be connected with the owner or any senior member of management. Every request has been refused. A company that stonewalls customers from reaching anyone above a customer service rep, especially after property damage and a safety incident, is hiding behind its front-line staff rather than taking accountability. If you're considering Mass Save's insulation program, ask specifically NOT to be assigned HomeWorks Energy. Based on my experience, this company should not be a state-approved vendor, and I'd urge Mass Save and the DPU to reconsider this relationship. Save yourself the headache and go elsewhere.
