"I had a wonderful experience with Founders Insulation. They were extremely easy to work with. It was easy to schedule an appointment, the gentleman who came out was knowledgeable and polite, and I felt that I received good information and they did not try to sell me something I did not need. Their quote was excellent. The work was scheduled and completed quickly. The installation team was courtesy, thorough, and knew their stuff. They were respectful of my home and went above and beyond. I highly recommend this company."

"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."

"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.

"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end  instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.

With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.

"The work that Metro Insulation, LLC did was well done. The contractor was very kind. I was a new member of Angie's List at that time. I didn't really understand so much what the big deal was. It wasn't a very large break in the price, but it wasn't a tremendous amount of money so I was glad we did this. I would recommend the company. The insulation they installed did end up making our house warmer. The price was considerably more than what I expected it to be, but I really wanted to get this done so I didn't comparison shop. I would shop around more before making a decision whether I would use them again."

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.
