"This took a couple years to fully complete as I have a Hip (Jack)-roof. The structure blocked off the last 4 feet from the end of the house, where the secondary roof takes over. Unfortunately, voids were inevitable because of all the obstructive joists etc. The next winter this was evident as the snow had melted over the areas that had no insulation. I took pictures, and Ryan sent a crew back to try again. I was happy, but the next winter showed the same voids. A week or so ago, I took out eve boards and found the void(s). Insulated it myself, but realized other end of roof would have the same issue. Called Ryan and he agreed (2 years later mind you) to fill it in for me. Then I drilled a small hole and put a bore-camera in and discovered all center bats had voids of 2 feet or so the length of the house. I scrambled (the night before appointment) and used a hole saw and cut out 7 additional holes through the 2x4 blocks. Too late to call that night and inform them of my new discoveries, I called (almost) first thing next morning to explain the job had gotten a little bigger than a 4x4 foot area. Once he understood the scope of project, Ryan said (as my doorbell was ringing) that they would do whatever needed to be done; just let them know, and call him with any issues. The workers figured out ways to get into the small openings with their hoses and made it work. Didn't argue, very respectful and stuck to it. I couldn't have been more relieved. Thank you for helping me with this issue of 30 years! I just knew my house was cold in winter, and hot in summer. I missed a chance to inspect this area when a roofing job would have allowed me to remove plywood and insulate it then, (as the original builder should have done). This was a "Good 'Cents' Home" from the '70s (PGE program) when insulation was being used to save energy. They just "missed a spot". Thanks everyone. Now my home finally makes 'Cents'!"

"Ulises was able to get in quickly and get the job completed insulating my shop ceiling trusses with batt insulation. I would have preferred white FSK instead of clear plastic but it would have put me way over budget Overall they did a good job"

"Westside Drywall was the only firm willing to do what I requested, which was to repair and not replace under-floor insulation. As a result, their price was much lower. An added bonus was that they could schedule the job in a few days instead of a few weeks or months."

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.
