"ThermaCore Insulation did an excellent job from start to finish. They removed and replaced the attic insulation, completed air sealing, rodent-proofing, sanitation, and replaced our air ducts professionally. Kamal was super helpful throughout the entire process and made sure every issue was properly solved. The crew was on time, respectful, and kept everything clean. Highly recommend ThermaCore Insulation for anyone needing attic or ductwork services."

"I had called Insulation Pros for an estimate with very short notice as well as two other companies. Conrad was the second person to give me a detailed estimate also was more then pleased to come out to my house and write me a real in hand quote. He was on time and very informative on the project. The following Monday the 2 professional men came to my house and did the job that I was promised and within the time that was allotted. Cleaned up and was off to the next shortly after seeing if I was pleased with the job. These guys are awesome. I do recommend Insulation Pros to anyone thinking about getting insulation done.
Thank you and all your staff.

"They were fantastic! From Elaine who took my call to Eric who came to the house, the professionalism, courtesy, responsiveness and service I got from Diamond was top notch. On one of the hottest days of the summer when our A/C went out (naturally), they went out of their way to get to me ASAP. Then when Eric came to do the service call, he was efficient and thorough and very clear about what he was doing and why. 
I couldn't recommend this company more.

FAQs for insulation service projects in Galt, CA

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.
