"I'm very satisfied with the quality of work this company does and the price was very fair. Aaron, the owner, was easy to talk to and after a short discussion, he knew exactly what I wanted. Mike and Dan did the insulation and even replaced a few floor boards at a nominal cost. They politely answered all my questions and you could tell they enjoy their work. If you want a professional job done at a very reasonable price, I would definitely give G.E.G. Enterprises a call."

"I will be using Koala insulation in the future. They were on time, Honest, courteous, and above all professional. The job was a total conversion rehab and new construction. The owner's Gene & Frank went the extra mile and got the job done to meet our scheduling needs. In addition, when consulting with the owners regarding spray foam in a section of the house, they did not try to upsell me and gave me good informative advice. Their staff is knowledgable and professional"

"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

"It went very well. Jon arrived on time and spent a good bit of time looking all around the basement and attic, even performing a home leak test which revealed that our chimney's damper doesn't perform as it should (already called for service) and that the insulation in our attic is up to code. He made useful suggestions about potential upgrades to our HVAC and water heater, as well as our thermostat. He installed energy efficient light bulbs in the few lamps where we didn't already have them. All told: a very useful expenditure of time and limited funds (the state of DE covering 3/4s of the cost!"

"Master Attic removed my old and rodent infested insulation, thoroughly cleaned out all the junk in my attic, vacuumed all the dirt, debris, and rodent feces, sealed all air leaks, installed rodent-proof cages around any entry points to the attic, sanitized the entire attic space and installed new insulation throughout. Francisco and his crew were fantastic! Great job by Master Attic! Thank you!"

"Had our 100 year old home insulated. It has made the biggest difference. Price was a bit higher than other companies we had quotes from.The main reason we chose USA is because they did everything from the outside by taking off pieces of my siding. So happy!"

FAQs for insulation service projects in Collegeville, 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.
