"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."

"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.

"We had radiant barrier insulation installed insteads of blown in insulation. It was laid in the attic rafters, upon the completion of the job the service provider could have done a better job of cleaning up. He also left some marking on our cabinet. When the gentleman came over to give us an idea of what radiant barrier is we never knew when he would be there, they gave us an estimate but then upon completion we wrote a check, but never received a receipt of payment, or work order showing completed work. All we had was the gentleman sign the estimate that we had been given two weeks prior to the job. And the installer did not have any paperwork saying that he did the job. But we had him write that on the estimate. I would expect more professional paperwork."

"It went rough, but we were both at fault. Had to say that first. But I am mostly satisfied. The outside sales person was on time for the walk through. He was nice and seemed knowledgeable. He had a lot of prior experience as a laborer before he became a sales rep. He was able to present his company and offer a quote on the spot. I agreed and gave him a deposit. Off we go. Right? Well, he based his quote on 700 square feet when it was actually 1100. That's why his price was low. You would think that I got a deal. But no. The labor crew only showed up with enough insulation for 700 SF. Not enough. So here is what we had to do. Introduce Jose. The lead man on the project. If it were not for him, it would have went south in a hurry. Turns out that Jose is a good person with a soul, and I am happy to "work with" a great person like Jose. APP is lucky to have him, and I hope they are taking good care of him. Just so you don't think I am fake, the "helper" that Jose had that day was worthless. Didn't want to work because he is a 20 year old kid who was out all night drinking and chasing girls (or boys), and was hung over. I did more 90% more work than he did (yes, I helped Jose. I have a good soul too). I let Jose vacuum out the old stuff, then I made him stop. He understood. Come back when you have 1100SF of insulation. Right? Before he took off, Jose up-sold me on insulating the bottom of my house (in between the floor joists under the sub floor)(under the house), applying a radiant barrier in the attic and switching from blown in cellulose with the pink panther batts. I ended up insulating under the house by myself. Nice. I communicated that to APP, but it got lost in translation. When the day arrived that Jose returned with 1100SF of material to finish the job, he showed up with two helpers. BTW, I had to request the APP office to please make sure Jose was who they sent to complete my job. Regardless of my implicit instructions that I subsequently made with the APP office, that I changed my mind and now want blown in cellulose again, and NO radiant barrier, Jose and crew still showed up with pink panther batts and radiant barrier. Whatever. The crew is there, lets get to work. The reason I only give them a B is because they installed the radian barrier wrong (in my opinion). I did research and radiant barrier should be one inch from the roof sheeting (plywood) if it's hot southern California. They stapled it to the 2x4 rafters so it's really 3-1/2 inches from the sheeting. Not sure if it is even radiating anything at this point. I think I just wasted a $1000. Even so, my neighbor asked me who did the job, and I ended up giving them the APP biz card, so I guess that was kind of a recommendation."

"All work done as presented. However, final test will be the next big rain to see if the leak is fixed. I feel confident that it is fixed. George was the estimator and supervisor of the work. He has many years of experience in the field and comes across as trustworthy and competent. It was a pleasure to deal with him."

FAQs for spray foam insulation projects in Garden Valley, 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.
