"Exceptional work. Founders spray-foamed my two crawl spaces in November 2023. These guys are super professional and efficient. From my initial call to the consultation to the actual job completion was about 2 weeks. The pricing is the best I found after getting three other quotes in the Arlington, VA area."

"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."

"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."
Owens Corning ProPink R-49 Blown-In Insulation. Our most popular product
These vents help your attic circulate air. With attics reaching over 120 degrees in the summer these are very important. They prevent mold and increase the lifetime of your insulation. Most other contractors miss installing these.
Look at the difference! Our foam is fire-rated which allows us to air seal around penetrations that contractors never could before.
Most homes have penetrations all over there attic. Imagine trying to blow up a balloon with a bunch of holes. It will never fill up. Now imagine trying to blow up your house with air conditioning and heating with a bunch of holes in the attic. It will never fill up.
Recessed can lights are notorious for leaking air. Recessed can light covers help with air-sealing your living space and prevent fires.

"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."

FAQs for spray foam insulation projects in Washington DC, DC

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
