My husband and I hired Rob to replace our front door, which had failed due to water leakage into the frame... and we are so glad that we did! He and his sons were extremely detail-oriented, thorough, and professional; every step of the process was explained/shown to me, and the end result looks and functions great. As Rob will tell you himself, he is likely not the absolute cheapest option out the...

Rob and his team are the very best! Over many years they've insulated a small room in our basement that used to have an oil tank, now used for a wine cellar. More recently, helped with our storm doors, winter and summer panels. And in 2020 new insulation blown in from roof down through our full basement, 4 levels. Our 1893 boarding house is now tight and sound. The gas company earlier in Jan. 2021...

In estimating the project, Rob Calnan was very detailed and professional and immediately responsive to my questions. The door had to be ordered to custom dimensions and he was communicative about the delivery schedule. He and his crew did a careful, thoughtful job in installing the door. His estimate was accurate and we are happy with the work he did.

Had a great experience with Calnan Energy Systems. On our first call Rob was very generous with his time and expertise. Our job was a little nontraditional; we have an unfinished basement that we're using for a workout space, but wanted to prevent the debris fiberglass batts in the ceiling from getting into the air. The solution was to use Tyvek to seal up the ceiling. A bit of an oddball job, but...

We had a terrific experience with Calnan Energy Systems. Rob was an invaluable resource as we sought out insulation contractors and performed a full insulation upgrade on an old Victorian during a major renovation. Rob enrolled us in an energy savings program, performed the preliminary energy audit, and guided us on what to look for in a top notch local insulation company (since he was unavailable...

Mr. Calnan and his crew did a great job upgrading our attic insulation, which involved several different tasks. Everything was clearly explained to us. The workers showed up promptly, everyone was friendly and polite, and they took great care to clean up after themselves. Recommended without reservation.
