"The garage ceiling was insulated by Lehigh Valley Insulation because our bedroom above the garage was always cold. After completing the job, we immediately felt the difference in the temperature of our bedroom. Thank you for such a great job."

"G.E.G. did a great job installing blow in insulaltion in my attic. They were quick and prepared. My only wish is they would have been able to pull up more of the unused attic flooring and gotten more insulation under it, though they were able to increase insulation in other areas."

"Bulldog was very knowledgeable and did a great job installing the insulation. I had to have them come back out to take a look at some of the insulation that made it's way into my basement, but they were very timely in getting this resolved. Overall, a great experience at a great price."

Customers say: Quick response

"The guy who came out was great. I was expecting to need to spend a lot on adding insulation to the walls and attic. The guy went around with a thermal camera and checked various spaces and recommended some stuff that I could do myself or hire an inexpensive contractor to do. Very happy that I didn't need to spend thousands of dollars!"

"Contacted Master Attic via Angi and Alex, the technician came to evaluate our attic and crawl space (2 separate spaces in our house). We heard critter noises and our upstairs was hot in the summer. The insulation was original to the ~30 year old house, so we know it's about time to get it done. Alex checked both spaces and showed us photos of problem areas. We have an estimate and Alex explained the details of the work involved. The team came within the week (we lucked out to take the spot of a cancellation), and everything was done as expected. There was a lot of work to remove old insulations, vacuum all debris, sanitize the space, seal all air gaps, install baffles, rodent proof, and install new insulation. The work was completed in around 6 hours, the spaces are now clean and tidy - quite unbelievable given how they were before. We went for the heavier insulation which is reflected in the project cost."

"Good job covering things and blowing in the insulation. Not such a great job spackling the holes but I guess that is easy enough to fix. Hopefully the insulation will help. Guess we will find out soon."

"We have worked with many different contractors over the years and have been turned off of construction in general. None of our previous projects have ever gone smooth. The opposite can be said about home genius Exteriors! Joe was in communication with us throughout the project and made sure any issues and concerns we had were addressed immediately. This has been a really good experience and I highly recommend home genius Exteriors."

FAQs for insulation service projects in North Wales, PA

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.
