"My son recently purchased an older home that had very little attic insulation. After Rob's team finished adding fiberglass insulation the A/C turned off almost immediately and the home remained at 74 degrees even though it was over 100 that day. I was very impressed and plan to have them come inspect my attic next !"

"Tech who showed up to do inspection was thorough. Climbed into small attic, took pictures and explained what their findings were. Other inspections (I had 2 more) just popped their heads into the entrance and too my word for what may need to be done. Scheduling with Attic Construction was simple. They showed up on time (early). They let me peak up their as they cleaned up old insulation and remove rodent droppings (biggest concern). They finished within the day as promised and cleaned up after themselves thoroughly. Our home was well protected from dings/damages as they wrapped corners of walls, stairs etc. We have noticed improvement from having only 3.5 inches of insulation to now nearly 14-15 inches. They recommended a "combo" of batt insulation (Around the entrance) and blown in for the rest of the area. This allows you to pop in there with out blown in insulation falling all over the place. They also recommended and performed rodent proofing/sealing. We were sent photos of both before and after their work. I would highly recommend this company."

"After to job was completed the attic looked amazing. The insulation was perfectly level. I was impressed they did an excellent job cleaning up afterwards."

"The owner came out and did an estimate of the job needing to be done. Was very polite, professional and honest. I had interviewed 4 other insulation companies and they all said something different."

"Easy to deal with, good pricing, nice personnel, professionals, fast workers, thorough cleanup when finished."

"They were a bit over the rest of the company’s that I had out. But the pease of mind that I had knowing that they were going to do it right was worth it. During the bid Mike answered all my questions before I was even able to ask them. Made a great impression on me. They also worked well with me removing my old insulation myself. PLUS , they hauled off the old stuff for me at a great price!! Thx guys!"

"I used this company to clean my ducts and they were thorough and very respectful. This was not an easy job. They also found a terrible blockage in my dryer duct, which was an added service. Itzik came for the consultation and looked throughout my house, which is new to me, and let me know all of the things that needed to be done, including properly protecting the recessed lighting protruding in the attic. They did such a good job, that I hired them to put additional insulation in the attic and an attic fan that he recommended since my home did not have one and it was truly unbearably hot in the attic. I think this has greatly helped with the strain on my air conditioning. When I noticed the fan was going full-time and not cutting off when the cold front came through, I let them know it was not cutting off and even though this installation was months ago, he came out and let me know there was a defective thermostat on the fan and he would replace it as soon as possible. This was no mistake the company made, but simply a lemon thermostat, just like my vacuum cleaner. The fact that he came out so quickly and didnâ t attempt any excuses, made this a mega-star experience. I realize problems happen and itâ s personable people like this company and their true commitment to your safety and comfort that mean the most. I would give this company 10 stars if I could."
