"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

Customers say: True professional

"Moshe and his team at Attic Kings are amazing! When I contacted them, they got back to me almost immediately with a date and time for an estimate to install insulation. Moshe was very communicative, texting and calling to let me know when he would arrive. On installation day, Moshe made sure to keep everything as clean as possible, and everything went incredibly well. They are all so kind--would definitely hire again!"

"Umar and El rocks!! I met 15 people for quotes and I picked them because of their honesty and competitive pricing. My house was infested by rays and mouse. We can hear them scratching at nightime from the corners of several rooms. At first we thought it was racoons but after several quotes, pics and videos, we saw the rats and their droppings everywhere! Our biggest problem was the rodent proofing, but then we found out our fiberglass insulation was only one ir two inches instead of the standard 12 inch for comfort. Another problem was the attic opening was from my bedroom and they creatively suggest to create a door from the garage attic with latch and seal my private room entrance. There were many holes on the light gap so they help to put light caps and closed the big gap on my furnace area to save energy. They use foam and mesh wire. It took them 9 hours and what impressed me was that they don't take short cut in blowing the loose cellulose insulation into 12 inch. They told us they were coming back the next day to get more cellulose supply. I really appreciate their hardwork, professionalism, and honesty. El even helped me to fit my furnace filter which I really appreciate! The cellulose has limited lifetime warranty and 5 years warranty for the rodent proofing. We went up to the attic for inspection and was impressed at how clean and nice smell our attic is now! They really make sure we're happy and satisfied and to call them anytime if we have any problem. That's really standing behind your work and A++ customer service by Umar and El! I'm pleased to recommend Attoc Professional company by Umar and El!"

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

FAQs for insulation service projects in Pittsburg, 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.
