"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."

"The project was to insulate the home (1800 sq. ft) --blown in R38 for the attic and 6 inch BATTS (R-19) for the basement/subfloor to protect our newly installed hardwood floors and to provide insulation in general. Every aspect of the process from initial consult call to bidding to project completion was superb. Craig provided excellent customer service. He understood our objective was to get the most value for our investment. He showed up on time and performed the project professionally and seamlessly. I highly recommend this contractor for insulation services."

"They were prompt, efficient, and cleaned up after themselves. I am amazed at the difference the new insulation has made in our house. However, I am still waiting to receive my invoice/receipt for my records."

"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!!

"Joshua is great! I purchased the toilets at Home Depot and arranged for Joshua to pick them up. Well HD Lancaster location only had two of the HE toilets that I wanted, so the 3rd toilet was picked up in the HD Palmdale store. Joshua did all this with pleasure. He was on time, work was completed superbly and cleanup was on point. I will always call on Joshua for my Handyman needs..."

"Right from the get go Brian was very helpful. He was very up-front and patiently explained all the kinds of insulation and suggested which ones to use. He even went so far as to include the inside wall insulation for soundproofing at no cost since the project was large. Very easy to work with and flexible."
