"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."

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."

"Our first interaction with Atlas was with Shannon. As knowledgeable and personable as one could hope for. She clearly explained cost effective measures to better insulate our house. We opted for sealing and insulating our attic and weather stripping a number of doors. We were very pleased with the workmanship and the energy savings they produced. They also helped us get a PEPCO credit which reduced the overall cost of the job. A winner!"

Insulation questions, answered by experts

Although spray foam insulation typically has a higher price point than traditional insulation, the benefits often justify the investment. It offers superior sealing properties, which can lead to significant energy bill savings. Spray foam also provides excellent moisture resistance and soundproofing. Other advantages include improved indoor air quality by minimizing allergens, a long lifespan of 80 to 100 years, added structural strength to the home, and a straightforward installation process.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

DIY insulation installation is feasible, particularly for basic rolls or batts, if you have the right protective gear and knowledge. However, hiring a professional ensures even, full coverage for maximum efficiency.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.
