Constraction reviews in Waltham, Massachusetts

Rob Calnan has replaced 2/3rds of the windows in our house, and I only wish I’d known about him when I had the first third done. He’s replaced doors, trim, and siding as well. His work is always tidy and it’s nearly impossible to tell that something was replaced. He does a great job on our quirky older house. We’ve had him come back for multiple projects because he’s such a joy to work with. I picked Rob because he sounded like a man who knew doors six ways to Sunday, and he did not disappoint.

Rob shows up when he says he will, and communicates if he won’t be able to come. He’s on top of paperwork and follows up with me if I don’t follow up with him. He’ll add on extra little carpentry jobs for us, and has given me good advice about things outside his scope. He’ll come for relatively small jobs. He does not ask me if I need to double-check with my husband.

The closest thing I have to a complaint is that he often gives me very short notice for when he’ll be able to come, but I suspect that if I asked for more lead time he would be able to accommodate.

Rob and his crew were amazing in every possible way. They took the time to understand what I was trying to accomplish beyond replacing my windows and doors, and the final product shows. The work they did was impeccable, and they were very thoughtful, considerate and professional throughout. I can't say enough good things about them and the work they do. I look forward to working with them again in the future, and I would recommend hiring Rob and his crew without reservation.

Rob came highly recommended by a reputable roofing contractor that praised his attention to detail, trustworthiness and professional approach to business. I reached out for a quote on insulation work and he came out very quickly thereafter to walk through my house with me. After knocking out the first couple things on my insulation to-do list (replacement windows, weatherstripping door), I can confirm that his work is fantastic and he's incredibly reliable. Rob treated my house like his own and did a great job. If you're looking for a contractor that you can trust, Rob is your guy!

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.

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 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.

Beautiful building, inside and out!

Fast unloading brian is the best.

Unprofessional & incompetent.

Rude, dangerous drivers

This company is the worst. Their finance team is a hot mess. Go elsewhere or risk audit issues

drivers of this company are reckless and a danger to other drivers on the road.
