"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"Every time it rained we would get water in our garage and basement. Thought about getting water proof system installed for years and finally got it done with Rightway. We have had 2 serious rains since the system was installed and have not had a drop in our basement.
If you have the same issues as us i highly recommend you finally get it done and use Rightway and you will not regret it.

"When Mike did the free estimate, he told me it wasn't the walls where we were losing heat. It was my crawl space. Also, totally above the work of insulating the space, he noticed an air duct was disconnected. He got the straps needed to fix the vent and didn't charge me. Excellent customer service. He was neat, on time, and quick with the insulation."

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.
