"Dave and his brother, Allen, were very personable and explained what was wrong in our attic and what they planned to do about it. I hired an electrician to replace all of the antiquated fire hazard nob and tube wiring with up to code wiring. Then I hired a roofer to open up our closed ridge vents. Then Allen and Ben sprayed 12 inches of cellulose insulation into our attic. The men cleaned up after themselves, and made certain that we (the new owner and myself, the seller of the house) were pleased with the result. I recommend Mulder Insulation highly and with absolutely no reservation whatsoever."

"We thought Dennison Exteriors was very professional and communicated well. The quoting process was informative and the price was competitive with other established contractors. While there were some bumps in the road (current labor shortage, delays in material delivery, and bad weather), the crew was very helpful and Scott Dennison was responsive to all of our questions and concerns. I believe the quality of the work is very good and would go to them again for this sort of work."

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.
