"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

Windows and insulation done. â … Top notch service from the consultation, to the schedule work, the start of the tear down, the installing and the final clean up.

"These guys were great. Allen met me at the door with a firm handshake told me what they were about to do and if I had any questions just ask. Leo was just as professional during insulation and got the job done in 3 hours. Dylan kept me up to speed during both projects and was very helpful. Easy reccomendation."

"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."

"We had a wonderful experience with this company. We live in a 1920’s rowhouse in NW DC with a very drafty first floor. The crawlspace had old batts and we were looking for an upgrade with foam insulation. The team that completed our project was professional, timely, clean, and very wonderful to work with. They removed the old insulation and disposed of it prior to spraying the new insulation. It’s been about a week since the project is complete, with a very chilly and windy week in DC, and we could not be happier with the results! The draft is gone, the heat is running significantly less, the house is warm, and the temperature between the first and second floor has been regulated. Highly recommend for anyone seeking a warm and cozy house!"

"Working with Dan Roberson and his crew was a pleasure. They removed old asbestos containing insulation from our attic safely and quickly. They cleaned and disinfected the attic, and then put in new insulation. They also removed old plastic sheeting from our crawl space and put in new plastic and foam insulation. They are very reasonable in price, great to work with, and leave the house cleaner and in better shape than when they came. Would definitely recommend them."
