"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."

"

Our primary bedroom is above the garage and even though we have a newer home, you can feel cold air coming thru the floor.  It's the coldest room in the house by far.  Ed's team came in and placed foam insulation in the garage ceiling.  He gave us $100 off for Angies list discount which was nice.  They cleaned up well when done.  Now that it's warm out I can't grade the quality of the work until winter again because I won't know till then if its helping with the problem.  I will come back and update then.  We had been quoted over $6000 by another company to do the work so hopefully this works and comes in far cheaper.

"My experience with AGL e ceded my expectations for the following reasons: 1: They invest the time to educate the customer Spray foam isn't your father's fiberglass insulation. Because it is still a relatively new product, there are a lot more questions that arise as a result. Of all the contractors I interviewed, AGL took the most time to help me understand the science behind this cutting edge product. This was especially important because I was planning to install a new roof as well, and I wanted to ensure that spray foam insulation wouldn't harm the new roof. 2: Expertise Simply put, every time I told a competitor I talked to a contractor about spray foam, the first company they always said was AGL. They are the leaders in the area for spray foam insulation. 3: Customer Service Jeff and the entire team provided great service and walked me through the process 4: The installers These guys are real pros. They were there when they said they would be and they cleaned up well afterwards Spray foam insulation is the best investment I made in my home. It isn't cheap, but the product will pay for itself over time and the house is much more comfortable. Thank you AGL!!!"

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.
