"David and his team were very professional and the work they did was excellent---we could tell the difference the next day. The temperature on the 2nd floor is several degree lower than before due to the new insulation and feels much more comfortable. David has solid knowledge regarding insulation and he explains things clearly. Definitely would recommend David and Prudent Homes to my friends and neighbors."

"Between Brad K., the company’s support team, and the crews who come out to do the job and execute the work, you cannot select a better company to help you make your home energy efficient and reduce your utility bills by insulating the house and sealing your duct work. As for Brad K., the job begins with Brad coming to your house and conducting an Energy Audit. This gives everyone a far better understanding as to what needs to be done in your home. And, Brad concludes with conducting a “ Test Out,“ to see the improvements. Pepco will offer you a partial rebate for the work completed and they are very satisfied with a 20% reduction. As for us, we hammered Brad with dozens of questions over the course of time before and after we ratified an agreement. In every case, Brad was extraordinarily responsive especially with him being burdened performing audits throughout the day and being offsite. We couldn’t be happier with Brad’s performance. The same goes for the inside team including Jeff, Gordon and Ashley. And, everyone of the guys and their team leads who came to the house not only focused on executing their expertise, but were also very customer focused. In our case, the “test out demonstrated a 36% reduction,“ and Brad believes the partial rebate will be even greater. A Little Constructive Feedback Here: Be sure to ask and fully understand what needs to be done prior to the crews arriving. We had three teams over three days (not in a row) and learned at that moment what more needed to be done to fully finish the job. This will minimize to virtually eliminate any further challenges for the crews and yourselves. However, the job was completed. Over the next 45 days or so, after our utility bill fully cycles, we look forward to seeing the results of Atlas’s work and the reduction in our utility bills. Atlas Home Energy Solutions is Your Best Buy. We are certainly available to provide any further references. RichandJames Peterson Silver Spring, MD (301) 592-1616 Email: [email protected]"

"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.

"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."

"I hired Atlas Home Energy Solutions to remove old insulation and replace it with the foam technique. However, I ran into numerous unexpected problems due to a slow leak from old pipes. It took awhile to sort out. Atlas Home Energy Solutions gave me lots of expert advice. They were willing to come out and review the situation. They were also willing to reschedule and wait until another contractor dealt with the water issue and its ensuing problems. They helped me make some difficult decisions before they could insulate the crawl space. When it was ready for them to come and insulate the area they bumped their schedule forward to get it done. This company did sterling work. Their expertise and professionalism were outstanding. They really know what they are doing and guided me through a more protracted process than originally envisioned. I would highly recommend them to anyone."

Insulation questions, answered by experts

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

Also known as sound-dampening blankets, acoustic blankets reduce echo in a room. They come in different thicknesses and materials, and they can be nailed or glued to walls.

Yes, many professionals offer insulation options, such as insulated siding (including insulated metal siding), to improve your home's energy efficiency.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.
