"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"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!"

"I contacted Atlas not because of high energy bills but because of noticeable summertime temperature differences between the first and second floors. My home is 32 years old and had never had the ducts cleaned and I suspected there was leakage from seams in the duct work. While the house was built to the then current (1988) code levels, the code is now more stringent. For example, my attic insulation was R30 where code is now R50. Atlas first performed an energy audit. Based upon that outcome, they recommended: (1) rerouting the bathroom exhaust fans through the roof, (2) additional insulation in the attic bringing it to R50. (3) closed cell foam sealing in the main and garage attics where appropriate, (4) cleaning the heating/cooling ducts and (5) using the AeroSeal product in the same ducts. I opted for all of these services. The work was spread over 3 occasions, each no more than 2 days duration with most completed in a single day. Their friendly work crews were very attentive to my property, made sure to put down drop cloths throughout the house and generally made certain everything was clean upon leaving. They kept me informed throughout every task and showed/explained what they had encountered. My ducts certainly did need cleaning, even though it’s always been a smoke free home environment and without pets. The benefits of this work have been fantastic. The AeroSeal process yielded a 98% reduction in duct leakage. I can tell very little temperature difference between the first and second floors now. I’m expecting more noticeable improvements during the winter months. I strongly without reservation recommend Atlas Home Energy Solutions."

"Debbie showed up on time and seemed knowledgable about insulation. However she had a hard time answering my questions because she was overly fixated on price. That's not necessarily a bad thing but it got in the way of me really understanding the answers. When the quote came in it was very resonable but when i emailed with a follow-up question concerning warranties, the lack of record on Angies List (despite being in biz for 100+ yrs) and a sub-contractor she was going to use for an exhaust ventilation, she wouldn't put some of the answers in writing until after I committed to using her company. After reviewing all of the quotes we received we finally decided to take a leap of faith because she seemed knowledgable and the quote was fair. i emailed saying we wanted to move forward and asked if i could i now get the informatoin i requested in writing. Unfortunately it's now been 5 days so we are moving in another direction. I bet the company does quality work but it won't be with us.

"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 insulation service projects in Monrovia, MD

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
