"Upstairs would not cool down with the unit on, called indoor mechanical and Robert and Josh came out within 24 hours. Did a lot of testing and looked everything over and turned out needed and entire new unit. Had a price same day and an appointment set. They were on time, professional, cleaned and made sure everything was running right and even checked to make sure the kids rooms had good air flow to keep them comfortable during these warm spring days in NC. Could not ask for a better outcome to a crappy situation that is going to happen eventually when you own a home. Indoor mechanical will be my go to for anything they offer."

"Called Lillian about new gutters for my house. She came out and did a same day estimate. Done estimate on a Friday and had them installed the following Wednesday. Great service. This is the second time i've hired them and both times they did excellent work. Her team was very professional. Finished the job and cleaned up like you never knew they were there. I will hire them for other jobs in future."

FAQs for spray foam insulation projects in Wilmington, NC

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.
