"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!"

Office contacted employee on the road and he responded within 90 minutes. Came in, assessed the issue and proceeded to spray and then remove nest.  Did a little sweeping up of pieces dropped on the floor, but not a thorough job. Some bees were found the next morning and are still being found. Probably those who were not at home at the time of the process.  Left the removed insulation which could have contained more bees? Best thing I can say he came immediately and removed most of my concerns. There is a 60 day guarantee, so we will see if we need to call them back?

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.

"These guys are amazing!! I was researching companies late at night and requested a quote off of their website. They responded immediately and were able to come out as early as the next day. We have 30 feet of duct and they were able to clean all of it. A few days later I was still receiving a notification on my dryer that there was blockage and they came out within a few hours. They found there was additional blockage within my dryer and cleaned it out at no additional cost. Absolutely great customer service! Will definitely be hiring them again in the future!"

"It was great.  We have used JA Drywall previously to do some soundproofing insulation in our living room. So when we had some leaking from the roof that damaged the drywall of our second floor bedroom, I knew who to call to have it repaired.  Juan and his crew were great.  They were very efficient, in and out in just a few days.  They worked around our schedules and they were very clean.  They completed the job and it looks great, just like new.  Plus with the new insulation we have noticed a dramatic difference in the warmth of the room, much more energy efficient.  Thanks Juan and JA Drywall for another great job!"

"From my first email and phone contacts to his visit for an estimate, Larry was professional and very helpful. We received an original estimate that was very competitive with other contractors but the difference with Larry, is that he did not try to get us to do other unnecessary work in order to jack up the price. Even with the addition of cutting and installing trim around the doors and windows, his estimate was the best one out there. Larry and Raphael arrived right on time Monday morning, prepped the room by putting down heavy duty paper on the floor, removed the old drywall, installed insulation to three walls, and then cut and hung new drywall to four walls. Larry and Raphael returned early Tuesday morning to finish with the drywall as well as to cut and install trim to two doors, two windows and floor trim. They even did some touch-up work to problem areas in our ceiling that was not covered in the estimate. Larry and Raphael removed all of the trash from the room and then cleaned the floors in the bedroom as well as the hallway and the entryway. They did such an awesome job with the room that we will definitely have them back to work on our kitchen and our bathroom. I cannot express just how happy we are with the work that Larry and Raphael did, they do excellent work and even tolerated our jumping and yapping puppy.

"It's been a few years and I couldn't be happier with my new roof. We had a little bit of a hiccup during the job - it took about a day and a half and went into the evening hours, when the salesperson had assured me they would be leaving by 6 PM. But a foreman came to discuss it with us and we worked it out. All of the wood underneath had to be replaced and the crew was able to get it done. It's very beautiful and hadn't had any issues."

Insulation questions, answered by experts

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.

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.

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.
