"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."

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!"

"I used AGL in November 2012 to foam the 3rd floor of my 1930's era Ardmore home which was under renovation. The crew did a fantastic job, they were on time and budget, and the house has been much more comfortable and almost draft free since the work was done. I will use them again when I renovate the 1st and 2nd floors."

"In the attic, we had wooden slats that covered the floor so they had to go under the floorboards. Although we were told by the salesman that there would always be a person on the other side of the wall to check for problems, the second guy was not watching and they blew a hole in the ceiling of the bedroom ( see pictures). They assured us that they would fix the hole, spackle it and repaint the ceiling. They did spackle the hole but only painted the area that they fixed - not the whole ceiling. And they did a lousy spackling job. We had to get someone else to smooth out the spackle and repaint the ceiling. We could have pushed to get them to fix the ceiling but it was late on the last day and we wanted the job done. As for the gel on the outside, the truck broke down due to the heat of the day and it took 3 days to finish the rest of the job including fixing the ceiling and the inside walls. Although the salesperson, did a first investigation of the house and said it could all be done from the outside, the workers found that one bedroom was covered in concrete so they had to drill from the inside of one of the bedrooms leaving many holes to be spackled. This time it was not so bad and we were able to sand and repaint that bedroom. But the workers could have done a better job of cleanup of the sparkle. It was all over the baseboard and the rug and we had to use rags to clean it up. We realize that things happen. And maybe we were too hopeful based on the salesman's pitch. But we would rather have had the salesperson tell us the truth about the possibility of drilling holes in the inside of the house even though he did a thorough inspection. All in all, we are hoping that insulating our house will save us a lot of money in heating costs. The manager was very accommodating, we saved some money by paying with a check vs a credit card. The workers were very nice and the lead person was very knowledgeable. Any renovation is stressful. We would probably recommend them because now we know what to expect. This company was recommended to us by a number of people. We have no doubt that the product itself is excellent. For that reason, we expected it all to go smoothly. It did not. Everything that could go wrong, basically did. It all got fixed but ... We did not plan for a hole in the ceiling, the truck breaking down and go into the shop to fix the problem with the gel overheating and not coming out of the hose fast enough, the concrete in one of the bedrooms that meant that all the holes had to be drilled on the inside of the bedroom and we had to repaint. So for those reasons, we are giving them a rating of fair. We hope your experience will be a lot better than ours !!"

FAQs for spray foam insulation projects in Philadelphia, 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.
