"I worked with Olmstead Brothers to have my pole barn spray foamed. I was so happy throughout the entire process. I have worked with several insulators through years of home construction, but Kyle and his crews bring a level of professionalism that is not typical in the residential construction industry. Kyle was extremely knowledgeable and easily answered all of my questions. The crew arrived right on time and did a great job of protecting all the surfaces to keep foam off my floor, lights and doors. They cleaned up nicely and were a pleasure to work with. I would recommend Olmstead Brothers to anyone interested in insulating a home, barn or any other structure!"

"Thanks to them, our bedroom in our new home was toasty for the first time since the temps dropped below freezing! They were fast, friendly, scheduled us quickly, and cleaned up every scrap of dust afterwards. The price was great, too. We will be working with them again on our basement insulation shortly, and would heartily recommend them to anyone who needs insulation work in this area."

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.
