Customers say: Quick response

"I highly recommend this business. I recently moved to the Lancaster area after purchasing a house that was built in the early 50s which needs some overdue maintenance. The attic insulation was old, worn out, and installed incorrectly. King Conservation gave me an estimate I was happy with and I agreed to having them do the work. They came in and air sealed the attic, removed the old insulation that was not needed, then installed new insulation properly. The team that came in were very professional and did a great work. I am very happy with the difference it made with the warmth in my house. I will definitely have them back to work on my basement insulation. 5 Stars!! Thank you Casey and the rest of the crew."

"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."

Insulation questions, answered by experts

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

The lifespan of crawl space insulation depends on how well you maintain your insulation and the type of insulation. Fiberglass will need replacing every 15 to 20 years on average if you don't have a vapor barrier in place. If you do have vapor barriers in place, then your insulation could last much longer. Spray foam insulation can last anywhere from 80 to 100 years. 

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.
