Very quick response getting the estimate and getting my job done. It's a family owned and run company - could not have been any nicer and did a meticulous job installing my new bulkhead. The price was very competitive."

"Insul-Kings is wonderful to work with. They called in the morning to narrow the arrival time, which is very considerate. Nate and his crew arrived on time and CRANKED like a well oiled machine. I have a 4' crawl space. You can barely crouch. No problem! That's why God invented knee pads. They foamed and installed the insulation like it was their own home. It was a work of art. and came out better than I imagined. They patiently indulged my "old man" inquisitiveness. The crew represented Insul-Kings very well. I highly recommend them. This was done through the Mass Save program. So the $2100 job only cost me about $500.00"

"After Fernando removed old flooring, he found hard-to-remove glue on the subfloor. He took time to carefully remove the old glue using a hot gun. Everything he did was done thoughtfully and meticulously. After new flooring was installed, he choose to return to improve one detail, so everything would be done perfectly. Fernando is honest and pleasure to deal with. I highly recommend him."

"After dealing with many disappointing contractors/handymen, Charlie & Richard were a (shocking) breath of fresh air and worth every penny. This company takes pride in their work and these two men truly want to do the best job for their customers in the long run. They do not cut corners at all and have extreme attention to detail. From the beginning, Charlie was organized, responsive and detailed in his quote. Over the course of 2 weeks, Richard and Charlie were consistently punctual and took great care to be respectful of our home (always used drop cloths everywhere they walked, swept/cleaned up after themselves daily & used the proper machines/filters so dust wouldn’t end up all over our house). The painting and drywall repair came out beautiful! I only wish I found this company sooner, but we will definitely be hiring Charlie & Richard again!"
