"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."

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!"

"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."

"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."

"I can't say one thing bad about this business: very professional, reasonable price, and they cleaned up that you would not know they were ever here. I will certainly recommend to anyone adding insulation to their house and like us insulating the garage. Excellent job to Hassan and his team."

"We hired USA Insulation to blow insulation into the ceiling above our garage. Their customer service team was very responsive, had great communication regarding visits, and provided a quote onsite after viewing the job. The job was completed as promised and all the workers were professional and courteous. I also liked the insulating material they used which did not give off fumes like some foam insulation, and was not itchy like fiberglass insulation."

"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."

Insulation questions, answered by experts

Historic architectural features heavily impact insulation service. Pre-1940s Doylestown homes feature balloon framing, requiring contractors to install fire blocking alongside new insulation. Original plaster walls limit access points and demand careful drilling to prevent damage. Additionally, rubble stone foundations trap moisture and require specialized interior spray foam. If your PA home features a Cape Cod layout, the sloped ceilings and knee walls restrict access and demand specialized installation equipment.

Helpful?

Homeowners seeking insulation service in PA have several specialized options. General contractors handle standard installations, while certified energy auditors assess whole-home performance before and after the work. HVAC professionals offer packages that include ductwork sealing. For older Doylestown properties, spray foam specialists tackle hard-to-reach crawl spaces and balloon-framed walls. If you live in a historic district, hire preservation contractors who use methods that protect original plaster and woodwork without causing damage.

Helpful?

Unplanned expenses during insulation service stem from necessary safety upgrades. Discovering active knob-and-tube wiring or asbestos requires immediate professional removal before work continues. Sealing a home in Doylestown traps radon gas, making mitigation systems necessary. You will also encounter fees for local building permits and mandatory inspections. Finally, older PA homes with stone foundations hide moisture damage, requiring professional mold remediation before contractors install new materials.

Helpful?

Upgrading your home's thermal envelope during insulation service directly impacts several systems. In older Doylestown homes, new insulation reduces the heating load, which causes oversized HVAC units to short-cycle. You must also address attic ventilation to prevent winter ice dams. Additionally, active knob-and-tube wiring poses a severe fire hazard and requires deactivation before adding insulation. Always test for radon, as sealing the envelope increases gas concentrations in PA homes.

Helpful?

A major error during insulation service is ignoring active knob-and-tube wiring, which creates a severe fire hazard. Homeowners also skip pre- and post-project radon testing, a critical step in PA. Another common mistake in Doylestown involves blocking attic soffit vents with new material, causing destructive winter ice dams. Furthermore, adding insulation without proper air sealing significantly reduces energy efficiency and leaves older homes drafty and uncomfortable.
