"The company did a good job replacing old insulation in our attic. There was a communication hick-up but the project manager we worked with - Jamie - was able to correct and resolve the issue."

"This probably the most professional service organization I've worked with in any capacity. They did a comprehensive audit and we discussed issues that could be remediated prioritized by the biggest bang for the buck and then they did the fixes we agreed upon. I always felt like I was dealing with an expert who had my best interests at heart - work that they could have done that they advised could be deferred. Ended up increasing the insulation in the attic which I'd known for years was a problem and sealing the ducts which has made a noticeable difference. I'd happily recommend Atlas to anyone who thinks they might benefit from a home energy audit and efficiency upgrades."

"Home Genius came by and installed my insulation into my attic and I couldn’t be more thrilled and happy with the results! I noticed an initial change with the first temperature drop of the winter! And I wasn’t cold one bit! Angel And Michael were both professional and knowledgeable and were available for any questions or concerns that I had! Thank you to Home Genius for my new roof and my new insulated attic! I would love to recommend them to all family and friends!"

"The initial people that I worked with were great. The installer was a different story but not by fault of his own. Despite the bumps that were ran into, everything went really smoothly. Just keep in mind that installation is messy!"

"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."

"The team from Atlas did an excellent job of installing spray foam in my attic, adding additional loose fill in another portion of my attic, and sealing my ducts. Would certainly hire again for other insulation projects and highly recommend them."

"We hired ROI Construction for replacement windows and were satisfied overall. They were open to price negotiation (we had competing bids) and flexible on scope, we added shutters at a reasonable cost. One install issue came up, but they resolved it within a couple weeks. Communication was steady throughout. Would definitely consider working with them again."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Germantown, MD

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
