"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."

"Highly recommend. Exceptional and professional service from their contractors and most especially by Nolan Walker (Performance Consultant). Nolan showed photos taken of my home's ductwork and insulation and provided a list of options and the cost of each project so that I could make a well informed choice of which projects to pursue. He took his time and was honest and understanding - not aggressive like other companies I have dealt with. His test-out and follow-up appointment was just as thorough. It was a pleasure working with him."

"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 would just like to thank this company for the work they did in my home! Iâ m very late writing my review but I wanted to see how different my home felt since having this service. Complete Home Solutions serviced my house on November 20, 2020, The crew consisted of Brad, Jason, Aaron and John B. There was another individual who did my drywall work, but I didnâ t get his name. There are no words to describe how much I appreciate your professionalism, knowledge, experience, cleanliness, kindness...etc. You guys did such a wonderful job! Since getting insulation put in my sonâ s room, I can feel the difference, a huge difference!! Also, I would like to thank Noah for the first initial visit and explaining to me in detail about the difference in the products. If youâ re looking for a company to provide service to your home, thereâ s no need to look any further! Iâ m looking forward to hiring them again, for my crawl space."

"A Hight on Homes were amazing to work with. We've now used them 5 times over the last 5 years and each time they were quick, professional, and saved us thousands of dollars over competitors. We started with a free home energy audit they were offering. They then helped us apply for government rebates to get our entire home weatherized which cut our utility bills in half! They helped inspect our roof after a hail storm, which only needed minor repairs. They helped us when our heat pump was on the fritz and offered a substantial rebate on a replacement heat pump. And then just this month we called them again when our water heater went out so that they could help us get that replaced and again, apply for a rebate for getting an energy-star rated appliance. Bobby and his team know this business so well and are some of the kindest people we have ever met. Get your home energy audit from them so that when you have an appliance go down they will be ready to help you apply for energy rebates much more quickly."

Insulation questions, answered by experts

In Silver Spring, insulation service contractors often specialize in areas like attic insulation, crawl space encapsulation, and wall or basement upgrades, each requiring different expertise. Some focus on spray foam or blown-in cellulose for energy efficiency, while others handle weatherization or thermal barrier installation. You’ll also find pros offering energy audits, air sealing, and moisture control—services especially valuable for Silver Spring’s mix of historic and modern homes.

Helpful?

For insulation upkeep in Silver Spring, keep a moisture meter to monitor dampness, a digital thermometer for spotting cold spots, and a flashlight for attic or crawl space checks. Stock weatherstripping, caulk, and foil tape for sealing gaps, plus expanding foam for hard-to-reach areas. A dehumidifier is useful for controlling moisture, and protective gloves and masks are essential for safe handling during inspections or minor repairs.

Helpful?

To keep insulation projects family-friendly in Silver Spring, schedule work when children and pets are out of the house, and use temporary barriers to block access to work zones. Opt for low-dust, low-VOC, or natural insulation materials to improve indoor air quality. After installation, ventilate the area thoroughly, clean up debris, and check that access points to attics or crawl spaces are securely closed to prevent accidental entry.

Helpful?

In Silver Spring, insulation projects last longer when contractors select materials with the right R-value for local weather, address thermal bridging, and ensure thorough air sealing. Managing humidity and ventilation is crucial, especially in older homes. Using pest- and mold-resistant insulation helps prevent future issues. Adhering to local building codes and performing detailed energy audits also contribute to a more durable and effective insulation upgrade.

Helpful?

In Silver Spring, signs your insulation may need replacement include persistent drafts, rising energy bills despite regular HVAC use, or rooms that never reach a comfortable temperature. Visible mold, musty odors, or damp insulation point to moisture intrusion. If insulation appears compressed, sagging, or has visible gaps—especially in attics or crawl spaces—it’s wise to schedule a professional evaluation for possible upgrades.
