"Ace was the lowest price and used the best insulation material which was fiberglass not cellulose. They showed up when expected and did a good job, we know, my husband was a building inspector before he retired."

"They came out to look and suggested that this was not an insulation problem, but a problem with the duct work for the A/C. They had recommended one of their A/C subcontractors who did an excellent job."

"We have a 1970's and we decided to have an energy audit by Landmark Construction. It was clear that our house have some energy issues and was in need of a any type of energy overhaul. The report that was prepared for us by Charlie and his office staff, was comprehensive, clear to understand and revealed that the ducts at the attic was not sized appropriately. In addition to that, the furnace/AC in the smaller unit was old (and original) and had to be replaced. The recommendations that Charlie told us, included a new furnace/AC, new tankless water system, hot water pipe insulation, building sealing, the insulation and new ducting throughout the house. This was the best investment we ever made. I could not believe the difference in our utilities bill. Charlie and his team were great, professional and experienced. I wish we did these 15 years ago!!

"Good customer service and were flexible when scheduling the work to be done. Can already feel a bit temperature difference in the attic where the insulation was done and the finish job makes the attic very bright. We have gained valuable space having had this work done."
