"I have used A+ Insulation for two separate projects. Shelby, the estimator, was responsive, knowledgeable and friendly. The installation crew was quick and through. They were easy to deal with and they didn't leave a mess behind. Overall, I got great service and a great product for a fair price. I would recommend A+ insulation and I'd use them again."

"I highly recommend Insulation Pros of KC for your insulation needs. Kyle the Sales Manager: made it easy to understand what I needed. Josie the Office Manager: took the time to answer my questions when I called, and was the one responsible for my decision to go with Insulation Pros. The installation crew: Devon, Tyler and Leo were a great team to work with, very personable and just all around nice guys who did a great job with the installation. Tanner - the Production Manager, who came by to see that everything was going like it should. From the first meeting with Kyle to the time the crew drove away, it was easy and pleasant to work with this company and they did a great job. Attached are pictures to show the 22" of insulation in my attic! :)"

FAQs for insulation service projects in Lexington, MO

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.
