"After getting quotes from a few companies, we chose ThermaCore Insulation for our attic insulation replacement and are very happy we did. The crew was hardworking, professional, and paid attention to the details. They removed the old insulation, cleaned everything up, and installed the new insulation efficiently. The house feels more comfortable, especially during the afternoon heat. The entire process was smooth and stress-free. Highly recommend ThermaCore Insulation to anyone looking to improve their home’s comfort and energy efficiency."

"Abdullah came by this morning and did a thorough investigation of where the rats are continuing to get into the walls of my house. He checked the traps set in the attic, went up on the roof to check for any entry holes, sprayed foam on a couple potential entry holes on the back of the house, and secured my dryer vent and hose. He answered all my questions professionally, and was efficient and courteous. I highly recommend his services."

"It was fantastic! The company was very helpful when my construction was a little unusual. They found a great way to install my insulation!!the workmen worked tirelessly and I now have a very warm home. I highly recommend this company!!!"
You will never look at your home the same when you see what "Stack and Draft” is doing to waste energy.
Window Replacement
When you heat your home the hot air rises and begins to “Stack” pressure on the ceiling until it finds an escape route around the many holes hidden in the construction where walls and light fixtures meet the ceiling. The hot air leaking creates a draft by pulling in cold air from outside.
Window Replacement
The more you turn up your thermostat, the more "Stack" is applied to the ceiling, accelerating the icy cold "Draft" right behind it.

"I was happy with the job that was done. It provides insulation plus a vapor barrier. He put in a radiant barrier. It looks almost like tinfoil. They crawled around under the house installing it. It insulates better then conventional insulation. My house is warmer when it is cool and cooler when warm."

"They are very good about calling to schedule our semi annual maintenance service visits. They call with a reminder several days prior to the scheduled visit and then again the morning of their visit with an ETA.
They are always on time and are extremely professional. They line the carpets with plastic in the areas they will walk over and wear booties over their shoes before coming into the house. They are thorough about explaning what they did, how everything is running and if anything is wrong they will explain what they did to fix. If you have a favorite technician, you can request them to be the one to come out for the work to be performed.
We used to them install a new hvac system in our home 4 years ago and had them extend duct work 2-3 years later. We decided to use them for a general maintenance program after the general warranty period was over. They have been maintaining our systems for almost 4 hears now. We are very happy with their overall service and highly recommend them for any HVAC needs.

"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 spray foam insulation projects in Sacramento, 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.
