"Matt was very good about keeping all appointments and very friendly. His work on the insulation was nice and neat and very effective. Good adhesion in all surfaces, and he even made a special trip back on our small job to finish insulating several windows. Matt gave the best service and best product of all the contractors I’ve had to hire in the last year. We may ask him to come back and insulate the rest of the garage!"

"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."

"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!"

"Ace was the lowest price and used the best insulation material which was fiberglass not cellulose. They showed up when expected and did a good job, we know, my husband was a building inspector before he retired."

"I hired Attic Masters to do an energy efficiency job at my house. The job included work in the attic, crawlspaces and major insulation at the garage. I’m happy with the overall service that I got from Adam and his company Attic Masters. The first consultation meeting was very productive and honest than the other companies that I met. I felt very secure with Adam's knowledge and the quality of his initial assessment. The overall work got increased as i decided that I wanted to do more work than originally planned. All the people that worked at my house (total of 3) were cooperative and the project rolled out easily. Adam did a wonderful amount of research about some things that were not usual. I wanted new insulation, new walls and more efficiency. After all the research that Adam did and the consultation he provided me with, we moved forward with the agreed upon plan and it was executed well. Adam and his team were willing to come over as needed for small finishing touches, questions, and more... He definitely went above and beyond on multiple occasions."

"Every person that came into our home from Tri-County was very professional and respectful.  They covered everything with plastic before removing the insulation and again when blowing it back in.  They cleaned up and disposed of the plastic, vacuumed the attic and cleaned up after themselves such that  you would never have known they were here.  The job of sealing the attic was done so well that the inspector made a comment that he had never seen a job done as well as this and ask who had done the work.  He gave them very high praise.  

The salesman we had, Bryan Zailer, was very knowledgeable and helpful.  He would call back immediately if we had a question and stop by to check on things.  I would highly recommend Tri-County to everyone for their insulation needs."

"They came out to look and suggested that this was not an insulation problem, but a problem with the duct work for the A/C. They had recommended one of their A/C subcontractors who did an excellent job."

FAQs for insulation service projects in Graton, 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.
