"We originally had Home Genius do our roof last year, so when it was time to do our siding a few months ago we called them again because of their exceptional service and professionalism. And now we just had some windows replaced and will be calling them for any future needs."

"Very established company with dedicated, respectful, courtesy employees. One of their products is blown-in insulation. We had them insulate our attic, foundation, and a crawl space under a room which gets cold during winter months. Our home is a large L-Shaped Ranch. It has made a difference in heating of our home. We had them take the old insulation out of the attic, which they vacuumed into bag and hauled away. Home Comfort also offers repair of driveways, where cracks have either sunken or raised the concrete. They repaired the few spots in my driveway, making it where someone won't trip on the crack and fall. I definitely recommend Home Comfort Insulation."

"The team were very professional, owner came at end of day to check up on quality of job (I asked him to look at my attic insulation, he could have easily conned me into paying for more - he didnt, and told me I didnt really need it... he found another insulation issue but recommended I solve it DIY style!)... so he wasnt interested in the $$$$.... Once he found I was happy with work he left me an invoice, no pressure to pay on the spot. The work has done exactly what he promised and I can recommend using them."

"Neil Umphress explained exactly how he would complete the installation of insulation in my attic including the type of material he would use. When a problem was encountered he discussed how it could be handled and left the decision to me. They worked all day with a lunch break Then another problem occurred and I thought they wouldn’t be able to finish in a day, but they pushed through, cleaned up and even insulated an area that was not in the contract just because it needed it. I have more work and will definitely call Neil Umphress to do it."
