"The garage ceiling was insulated by Lehigh Valley Insulation because our bedroom above the garage was always cold. After completing the job, we immediately felt the difference in the temperature of our bedroom. Thank you for such a great job."

"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 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."

Insulation questions, answered by experts

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

The R-value is a rating that measures an insulation's thermal resistance—in other words, how well it insulates. A higher R-value provides more protection for your pipes, and all pipe insulation materials should have an R-value listed on the product description or label. Each insulation type has its own R-value, which typically falls between one and five for most pipe insulation. When making a selection, Energy.gov recommends choosing a pipe wrap that is at least one inch thick, and the International Code Council (ICC) suggests choosing a material with an R-value of at least 3.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.
