"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."

"Stephen and his team did a fabulous job of insulating a space behind a bedroom wall and adjacent bathroom wall that was completely uninsulated. We suffered through two cold winters that heaters couldn't solve in these rooms. Stephen evaluated the project efficiently and then oversaw the work. It was performed beautifully by the team and they cleaned up before leaving. Everything was immaculate. Most impressed with this company and this project manager."

"Courteous, diligent, professional and fair priced. Without reservation I would highly recommend Q-insulation. They installed rock wool insulation in all the ceilings and on the vertical attic walls in our historic brick victorian. They were prompt, on time and treated my home like it was their own. Thank you Valeria and the crew."

"The gentlemen from Superior Insulation discovered a missing piece of duct work that was causing air from the cold air return of our geothermal heating unit to be pulling air from the unconditioned attic space above our second floor bedrooms.  My husband installed the duct work.
They put blown in insulation above our family room, above our second floor bedrooms and on top of duct work inside knee walls running the length of the house and also did spray foam insulation around some small doors into knee walls.
The work done by Superior Insulation decreased our energy usage by 40%.
We would recommend Superior Insulation to anyone.

Insulation FAQs, answered by experts

Upgrading insulation in York can make your home more attractive to buyers who value energy efficiency and comfort. Enhanced attic insulation and air sealing are especially appealing in PA’s variable climate, helping homes stay warmer in winter and cooler in summer. These improvements often result in lower utility bills and a more consistent indoor environment, both of which boost resale appeal and help homes stand out in the local market.

Helpful?

In York, tailor your insulation inspection routine to the region’s weather shifts. After winter, check for moisture buildup and signs of pests common in PA basements and attics. During humid summers, inspect attic insulation for ventilation issues and monitor for mold. In fall, focus on sealing air leaks around windows and doors. Winter is ideal for checking for drafts and ice dam formation, both frequent in York’s climate.

Helpful?

For insulation upkeep in York, keep a digital thermometer for checking temperature differences, a moisture meter for detecting dampness, and a flashlight for attic or crawl space inspections. Stock caulk, weatherstripping, and foam sealant for sealing gaps, plus plastic sheeting for vapor barriers. Safety gear like gloves and dust masks is essential, especially when handling attic insulation or making minor repairs throughout the year.

Helpful?

In York, look for water stains, musty smells, or visible mold in your attic or crawl spaces—these often mean insulation has been compromised. Insulation that’s shifted, appears thin, or has gaps around pipes and fixtures can reduce energy efficiency. If you notice increased drafts or your home feels less comfortable despite past upgrades, it’s a good idea to have your insulation professionally evaluated.

Helpful?

In York, rising heating or cooling costs, persistent drafts, or rooms that are hard to keep comfortable signal it’s time for insulation service projects. If your home was built before 1990 or the insulation looks compressed or discolored, it may not meet current energy efficiency standards. Frequent ice dams or attic frost during winter are also strong indicators to schedule an inspection or consider upgrades.
