"Founders Insulation did a very good job on installing insulation in ceilings! They were careful, courteous and cleaned up."

"They replaced our insulation while we were redoing the roof."

"Leo the installer and his guy were excellent and have amazing work ethic and the work was conducted in a professional manner. Omar came in and inspected everything and was kind and Iâ m so happy I got my insulation done"

"David Sampson of Prudent Homes did an amazing job, I could immediately tell the difference in temperature in the garage and our two pantries where Dave applied blown-in insulation directly above. He made sure to protect all soffits and recessed light fixtures. He also applied insulation around the attic opening and cover. The price Dave charged was well less than a competitor, and Dave was much more thorough in his initial assessment. Dave and his worker made sure to clean up where needed. I highly recommend Dave and Prudent Homes, and will definitely use them again for future insulation needs."

"I needed a company that would blow insulation into the walls of my basement. Terra Insulation did the job for me. The technicians were expert at drilling the holes, adding the insulation and clean up. They were professional and informed me of when they were taking a break, etc. They even replaced the disks and added drywall paste to ready the walls for my painter. I highly recommend this company for its dependability and expert installation."

"Window & roof insulation quick, easy, & affordable!"

"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

"Very professional. Fully explained the process before starting and showed photos of the areas that needed insulation in my home. Before and after photos. Used energy company rebates to reduce my out of pocket expenses and did follow up evaluation. I saw the change in my energy bill! Thanks!"

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."
