"the insulation they recommended saved me about 5000kw a year. the amount of money i am saving is far more the insulation payment on my Eversource bill. No money cost to me out of pocket and my electric bill dropped quite a bit. best move i ever did."

"
Troy was great!He is a little hard to get a hold of, but when he said he would show up, he did or called and told us he was running late every time.Our job was time and materials, so there was no bid before hand.Troy worked very hard while in the house, was professional and polite, did very clean work and left the job site cleaner than when he arrived.We scheduled Troy to come in to move all the water pipes and develop a solution to poor insulation / moisture barrier from when the bathroom was added to the house in the 1970s.  Troy took two days to do this part as he ran in to some problems that were not his fault (The house is 137 years old - this happens every time).  Troy was very creative in solving the moisture barrier and insulation problem.  He did excellent work replacing the sub floor and was able to match it perfectly so that the new tile floor would match grade level to the floor outside the bathroom.  He did use a sub-contractor for the pipe work, but Troy was always there while he was working.  The only thing negative was they forgot to put escutcheons around the pipes before they welded the valves on (Minor, but irritating).We then had to book Troy to return when we were done with replacing the tile backer board and installing tile floor and subway tiles on the wall.We booked him to return in 4 weeks (We are weekend warriors -  We knew it would take us at least this long).Troy returned as scheduled to complete the job.  He stayed and worked for 10 hours till the job was done.  He installed the new toilet and the pedestal sink we had purchased.  We also had him go ahead and replace all the hardware in the shower and install new shower doors.
Troy works very methodically - He may seem slow, but when he does it, he does it right (unlike other contractor / handymen we have used)
We are very happy over all with the work that Troy did and will use him again."

"The technician who came was a pleasant, competent professional who examined the unfinished attic to evaluateit w/r/t insulation only or insulation as part of a full finishing of the space. He took measurements and scratched out some information on his pad.. I told him that I intended to review my options before any decision. I offered payment at that time and he told me there was no charge for this service. It struck me as odd that he told me that what I had agreed to pay $19.00 for was actually free but I asumed billing would accompany an actual report/proposal. A month on I've never seen anything like a report although I have been charged via credit card for the inspection service. Perhaps the report-recommendation is still on its way? PLEASE NOTE THAT THIS REVIEW FORM REQUIRES A YES/NO HIRE AGAIN RESPONSE. I WOULD HAVE PREFERRED TO ANSWER UNDECIDED."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"The initial consultation was so informative - Dennis taught us everything we needed to know about windows, gutters and insulation! He took the time to answer our questions and promoted their quality products.   He explained the benefits of spending a little more money on quality windows and having professionals install them so they get done correctly the first time.  From there, everyone we spoke to or dealt with  in the company was so pleasant and professional.  The foreman (Gil) was well-versed in lead paint removal safety standards and did an absolutely beautiful job on the outside trim for the windows.  He's very skilled and finished the complete install over 4 days with the help of only one other equally skilled craftsman.  Any issues we had with the installation (all minor) were promptly corrected to our standards.   He also installed our attic insulation quickly which was no more than a couple of hours' work.  The gutters were installed in 1 day by another 2-person team that was equally skilled and hard-working.  They were also a delight to work with.  I'm sorry that I can't remember their names to give them a shout-out because they were very lighthearted and funny.   There were some miscommunications between the scheduler and the specialists, however, which did affect our schedule.  We're fortunate though that one of us is a homemaker and were able to adjust easily.  We understand that things don't always go as planned, but last-minute changes can be hard for some people don't have the luxury of an open schedule.  A stricter adherence to the schedule and clearer communications in regards to scheduling would have been ideal, but overall we were so delighted to work with this company and look forward to working with them again for our siding!  They have quality products, a skilled and professional staff, and they're local!  Definite recommendation for anyone looking for quality home improvement - worth every penny!!"

Insulation questions, answered by experts

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.

Yes, insulating your pipes can reduce plumbing noises because it dampens vibrations and reduces the transmission of sound, making your home a quieter place. So if you've ever been annoyed by the sounds of water rushing through your pipes or the clanging noises when someone turns on the faucet, insulation can help.

Periodic checks for moisture or pest issues ensure consistent performance.
