"This company came in a updated our 40-year old home insulation with new R-38 batting. We were impressed how much attention to detail the company has for removing old insulation, clean-up, disinfection, and installing new insulation. They also replaced a damaged dryer vent in the crawlspace. Nico and Jeremy were a great combo to work with from quote through install. I plan on calling them back in spring for another project."

"Moshe and his team at Attic Kings are amazing! When I contacted them, they got back to me almost immediately with a date and time for an estimate to install insulation. Moshe was very communicative, texting and calling to let me know when he would arrive. On installation day, Moshe made sure to keep everything as clean as possible, and everything went incredibly well. They are all so kind--would definitely hire again!"

"We had an inspection and we had to replace the insulation in the attic. We were able to get a good deal from this company after we reached them via a referral.
The work that they did was very good and professional. there were several employees at the house for the 2 days work that they did. We do recommend this company for any insulation replacement that you may need.

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.
