"We needed some drywall work done and H Drywall was one of three companies I contacted for estimates. They were the middle bidder, but I was so impressed with Harry’s (the”H” in H Drywall) on-site visit and his comprehensive proposal that I decided to go with them. I was not disappointed because Harry keeps on top of things and is quick to reply to messages. A bonus was their online payment system which is really convenient and provided instant confirmation of a payment. What truly makes this company worthy of a 5-star rating though are its employees. John, the foreman, is easy to talk to and has so much experience in construction that he solved any problems or challenges that occurred. He always kept us informed of their progress and made sure we were happy with the work they were doing. The rest of the crew Stuart, Derek, Chris, and Evan were all friendly, courteous (always aware that we still lived in the home), and did excellent work. Drywall replacement is messy, but these guys covered everything including the floors and they vacumed daily. The drywall removal uncovered some additional work that needed to be done and H Drywall provided a reasonable estimate to fix the problem. We also had them paint the living room, dining room, and kitchen areas. Thank you Evan for helping us choose the right color! This company, and I mean the whole company, definitely deserves a 5-star rating."

FAQs for insulation service projects in Princeville, HI

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.
