"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."

"i scheduled an appointment to get 3 missing shingles replaced. i saw the $149 deal that included a full roof inspection, replacement of up to 5 shingles, attic inspection and a few other maintenance tasks along with a $250 credit for future use. i really only needed the shingles replaced but i'm glad i purchased this deal. Howard (one of their head techs) arrived right on time for the scheduled appointment. first thing he inspected was my attic. he found a few issues and described them fully to me along with showing me pictures. he noticed one of my air ducts was not connected, which meant i was heating and cooling my attic for who knows how long and also meant my bedroom was not getting the right air supply either. to save me time in having to hire an HVAC specialist, Howard asked me for a roll of duct tape and was able to reconnect the dislodged air duct. he then spotted a leak in the roof about the size of a quarter that was dripping through the insulation. he also saw water marks in another location but wasn't quite sure how it got there. after he inspected the attic, he hopped up on the roof. he replaced the 3 missing shingles (didn't match my current shingle color but no big deal). he also found where the leak was coming from. apparently there was a bullet casing stuck in the roof which was causing the leak! after his work was complete, he gave me a full description of what he saw and a few recommendations. he answered any questions that i had. Overall, Howard seemed like he had a lot of experience and was honest. total time of the work took about 2 hrs 15 minutes from start to finish. i would use them again in the future for any roofing needs. he told me they do other work like windows and siding. my only negative was that my appointment date was about 1 month from when i called to schedule it. i'm guessing it's because they are busy and booked up but it was obvious after the quality of service that was provided. also, the pictures he took were supposed to be sent to me. it's been about 5 days now since service and i have not received them yet."

"First, a global test was done to determine where there was energy leakage. Then, the repairs and insulation were made. Finally, another global test was done to determine improvements."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

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.
