"Very easy to work with. The owner himself came out to give me an estimate. Mark completed the actual insulation. He was quick and he did a great job cleaning up the area after doing the spray insulation. Highly recommend!"

"The gentlemen from Superior Insulation discovered a missing piece of duct work that was causing air from the cold air return of our geothermal heating unit to be pulling air from the unconditioned attic space above our second floor bedrooms.  My husband installed the duct work.
They put blown in insulation above our family room, above our second floor bedrooms and on top of duct work inside knee walls running the length of the house and also did spray foam insulation around some small doors into knee walls.
The work done by Superior Insulation decreased our energy usage by 40%.
We would recommend Superior Insulation to anyone.

"Our experience with Q Insulation Consultants Inc. was a very positive one. They did a fantastic job start to finish. The Company manager contacted me within 5 minutes of receiving my email request for an estimate. We set up an appointment for the estimate that same day. The team doing the quote was the team that would be doing the job, which I appreciate because you do not have to bridge the gap in communication should there be a discrepancy between the service crew and estimator. Best of all the estimate was simple, straight forward and the manager was available to answer any questions you may have regarding the estimate and service. There were no hidden costs. The service crew was awesome! Punctual, organized, courteous, conscientious, competent and worked well as a team. With our attic being on the third floor, they took the time needed to ensure floors and stairs were well covered prior to starting the job. They worked non-stop at a consistent pace to provide a quality install. Could not be more pleased with the customer service, installation team and overall job quality. Very meticulous crew that cared about the quality of their installation. I highly recommend this company for insulation installation!"

"KES did an excellent job replacing our roof and gave us the best price. The workmanship was great and we appreciated working with Ron throughout the process. He walked us through the replacement start-to-finish and helped us pick all the options we needed. One of the reasons we went with KES is because of the additional services they provide when compared to other roofers, as explained by Ron. They use stainless steel nails and GAF shingles, which allowed KES to offer us a very good warranty on the roof, which was important to us. The skylight was done perfectly, also. We are very happy and would not hesitate to call KES again in the future when we need our siding done."
