"We had insulation installed a week earlier by Koala. During the insulation, Jasper (insulator) suggested another area that we might consider installing blown-in insulation. We agreed and the second job was performed on Friday, the 24th. Jasper and Richard were on time, the insulation project was well done and they left the area very clean. Would use them again."

"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."

"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.

His crew was also polite and hard working, they got the job done when they said they would and I’m so pleased with the results ! My home is the same temperature on every level and my energy bill is lower then it’s ever been. Thank you Bob and your team I will definitely be referring you to my friends and family."

FAQs for insulation service projects in Maryland Line, 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.
