For a thorough examination and cleaning, I just engaged Waltham's Attic Insulation & Roofing Services. James and his staff provided excellent service in a very professional manner. They did an excellent job cleaning our air ducts, dryer vent, and chimney. Their thorough work on insulation and Attic-Solution methodology particularly impressed me. Even their quote for roofing services was reasonable and truthful. I saved a significant amount of money by using their Mobile Attic Insulation & Roofing Services offer. James genuinely knows how to provide first-rate customer service. I heartily recommend them if you're in Waltham. You can get quality, value, and trust in one service!

Small & tight but quick to unload...you can blind side it in but if you don't want to do that then drive past spray foam to the end and make a 3 point u turn and come back. It's best to jack knife it into the dock that way the other cars and small truck can drive through there

Very professional group of people 👏 Loved there work and services. I will highly recommend them to everyone...

It's a good place to get material they are friendly and the prices is not that bad

Rob and his team are amazing to work with. They will go above and beyond to ensure that the work is of highest quality. The insulation job on my 70 year old house was complicated. Rob had to co-ordinate with roofers (i was also changing my roof), HVAC team and cleaners (mess from a previous job) to appropriately insulate my home. He was also able to get me a good rate on the HVAC work. He and his team are very considerate and ensured that I was fully satisfied. When issues came up, they would clearly and quickly communicate and help identify a cost effective solution. They are amazing at what they do and I can clearly see a difference in my home comfort level and not a moment too soon. For quality work, one does not have to look beyond Calnan Energy systems.

Quality work, owner is on site every day, true craftsmanship, reasonable pricing, and honest. Over the last 10 yearsand 3 different jobs Calnan's has replaced windows, sealed leaks, installed insulation, and done repair work on my 95 year old home. I had numerous windows that had rotting thresholds that other contractors had "repaired" that only lasted a few years. Also have had not so good experiences with other window replacement companies(one rhymes with "Fella"). Roband his crew has been a pleasure to do business with. Calnan's is a family owned company that wants to see their customers truly happy. I always feel they are looking out for my best interest and not just trying to make a buck. Now I don't even call for competitive quotes. I would give them 10 stars if I could!

Rob (the owner)came by and emailed me a quote. I thought it was a little bit on the high side and I asked if he could possibly cut it down a little bit and leave a step out. He mentioned it would be in your best interest if you went with my recommendation, or you’ll be calling me back to do something else. He was right! Rob and his team know what needed to be done. We purchased the house December 2020 and there were air gaps in the crawl space. Rob pointed this out and when the wind blew through that space last winter we felt a chill in the sunroom above. I would highly recommend Calnan’s.

As the former owner of S+H Construction, I have known Greenstamp for years. Last year we renovated our own home and Greenstamp did an outstanding job. They even came back almost a year later to touch up some areas at no charge. Great company !

Very professional, knowledgeable and pleasant to work with. Company came out, gave accurate quote, provided fast installation date, and was on time each day until the job was completed. Our house has a complicated attic, which several companies refused to even quote.. there were a couple of issues that occurred during install, but they very quickly resolved them! I would work with green stamp for any future insulation projects on our house. A+++

The men at Green Stamp arrived at 7:30 and worked straight until the job was done at around 4:00, not even stopping for lunch. They spent the first couple of hours just preparing the job, putting up plastic to protect the HVAC, etc., before they started spraying. They were very courteous and did a very good, clean job. I was quite nervous about having spray foam insulation in my home, having heard that if it's not installed correctly, I might have off- gassing. But Green Stamp was slow and careful, and the spray foam cured in a couple of hours, and there are no fumes whatsoever. Thank you Green Stamp! (Caitlin from Concord, Mass)
