"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."

"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."

"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 RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"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."

"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."

Insulation questions, answered by experts

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.

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?

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?

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?

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.
