"Troy was friendly, efficient and knowledgeable. I would highly recommend him for any insulation job. After insulating my parents home he was hired by my sister for her home and I’m getting a quote for mine also."

"Very easy to work with. The owner himself came out to give me an estimate. Mark completed the actual insulation. He was quick and he did a great job cleaning up the area after doing the spray insulation. Highly recommend!"

"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."

"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."

"I communicated with Ron directly and he was determined to solve our insulation problems. He had to remove drywall in our entranceway and add in insulation where there were large gaps and air was getting in. He had a worker drywall and patch up the wall. The drywall worker did an amazing job!
Ron also fixed an ongoing issue we had in our garage ceiling that was causing our living room floor to be cold and drafty. He worked around our schedule and made multiple visits to our home to fix the issue. We are happy customers and happy to say that the problem is fixed. We were very pleased with Ron and his company and do recommend him highly.

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
