Insul-Techs were hired to insulate my house. The scope of work involved insulating my walls, attic, and crawl space. The team installed different R value fiberglass insulation in the attic, walls, and crawlspace. They also installed spray foam insulation in one of my vaulted ceilings as shown in the pictures. I also got my garage walls insulated so that I can use that as a gym year round. They did an amazing job and after they were done with the insulation, we felt the difference on how cooler the house felt even when it was really hot outside Chris helped us with the scheduling and was a delight to work with. They are a hard working team who catered to all our requests and did everything to ensure we were satisfied with the job before they were done. Thank you Insul-Techs!
I was referred to insultech from a respected contractor. Luis came by for an estimate. During the inspection i was given options on the types of insulation and the insulation factor of each method. After further review of other insulation companies non were as professional in explaining the process or the materials used, and most of all they were much more expensive for the same work being chosen. The techs came in completed the job with the utmost respect for property. Communication with Luis and the front office was effortless and the response was done in a timely fashion. The insulation factor coupled with the mini split for cooling. What a difference. Customer satisfaction comes first. Great job InsulTech.
I recently had Insult Techs replace the insulation in my home, and they did a phenomenal job! The difference it made was immediate and noticeable. Their customer service was excellent from start to finish, and their pricing was very competitive compared to other companies I looked at. Luis and his crew were professional, efficient, and respectful throughout the entire process. It was truly a great experience, and I highly recommend Insult Techs to anyone needing insulation work done.

I recently had a fantastic experience using McHales for insulation at my house. Dan came out to my house to review the plans and provide a quote. He was very honest and did not try to upsell anything! A few days later, Dan's crew came out to complete the installation. They had everything completed in just a couple days. The crew was very professional and cleaned up each evening! It's only been about a month, but you can drastically feel a difference in temperature throughout the house! I would highly recommend McHales if you are looking for a great/smooth experience.
Great experience with McHales Environmental Insulation! John came over to our home, identified which walls did not have existing insulation, took measurements and provided cost quote bid for blow-in insulation the following day. We scheduled the job, and the crew came over on time and walked us through what they were going to do. They completed the job within a few hours, patched holes nicely, and cleaned up their work areas. We have felt a noticeable difference in our home insulation since the job was completed. They also helped us process an energy rebate. We would recommend McHales to anyone looking for blow-in wall insulation!
I have been trying to do the insulation in my house for a long time, but I only had luck once when I found McHale's Insulation. My house is old. It felt like an oven in summer, and in winter, like a fridge, until they did the blown insulation in the wall; wow, it's fantastic. What is the difference now? If you are looking for an honest and professional company to do the insulation your of house, you should call them. They did an excellent job; I have to thank them every day. It feels great.
