"We needed retrofit wall insulation and after checking around all the listings through AngiesList, Yelp, and others, we found that only Bay Valley and SDI does retrofit wall insulation work. We went with Bay Valley because the price was reasonable and they responded quickly and promptly (can't say this about SDI*). Joel was our estimator and he came out promptly at the time and date indicated. He was thorough and thoughtful on how he approached the job, not overselling or recommending things we didn't need. We live in an older house and he appreciated the home and looked for the most non-invasive method to take care of our un-insulated exterior walls. Bay Valley's approach is to come in from the exterior walls with the typical 2-hole process (high/low) to blow in the cellulose insulation. They sent two guys in and despite a couple snags in the job, they finished the job in one full day. Afterwards, they plugged the holes, textured and primed, and the next day came in to paint (our-supplied) paint. I was really amazed how well and seamless it all looked afterwards. They did a good job cleaning and even moved the cabinets in the garage back where they originally were. The real result? The mornings have been a little bit warmer than last week, but so far the heater has barely turned on over the past couple days. The house already feels warmed and less temperature fluctuations. We already got brand-new attic insulation last Fall, but the wall insulation really did the trick. A definite recommend to anyone who needs a good team to do insulation in their home. * dealing with SDI was a nightmare, unfortunately. With *several* calls about being in the ER, then lots of other excuses, it just didn't seem like they wanted to do the job or something. I originally made the request in August and this morning on Nov 10, I got a phone call inquiring if we still needed insulation done. sigh."

"We had had a problem with rodents in our attic and crawl space last year that we had solved. When we were installing new can lights in the ceiling this year, we discovered the problems that we had not solved—lots of rat droppings, a couple of rat skeletons, old, ineffective insulation, and generally a mess in the attic which needed a fix. We contacted Attic Pros based on the reviews of others and scheduled an assessment. Jeremy came on time as promised, and he provided a detailed assessment of the attic (and our crawl space below the house) complete with pictures and a recommendation of what was needed. We received a detailed estimate that evening with a plan to complete the work over two consecutive days. We scheduled the service for days that worked for us. Armando and his crew arrived promptly on day #1. They removed the old mix of batts and blown-in insulation, and vacuumed the entire attic eliminating all evidence of the prior rat infestation and disgusting mess. The provided pictures of the cleaned out space (which I confirmed with my own inspection of the attic) which was spotless down to the rafters and floor boards. They also completed vacuuming out and sanitizing the crawlspace and disinfected the attic space. They inspected all possible entry points for rodents and other pests and air sealed and patched all of the small holes around pipes, vents etc. with mesh and foam. All of the old disgusting insulation and other waste disappeared into large bags which were hauled away (thankfully!). They also installed attic recessed light covers over the ceiling can lights in the entire house to minimize air (and heat) leak around the fixtures. On day #2 Armando arrived in the early morning with a crew and a truck full of fresh batt type insulation. They spent the day re-insulating the entire attic with R38 batts. Because of a very narrow attic space in one area under the roof, they had to cut a new attic access in one of our closets to complete the job. They were efficient and answered all of our questions that arose, and when the job was complete, they left virtually no evidence that they had been in around the house, except for the very nice thick layer of insulation in the attic, which our furnaces already appreciate. Jeremy was in contact via text message throughout. In fact, after they had to cut the new attic access, Jeremy asked us whether we wanted it restored or whether we wanted to retain the new access for future use. We decided to keep the access, so Jeremy sent a member of the crew out the following day; he framed the access and placed a trap door into the closet even painted to match the closet color! Overall, we were very pleased with the job. We are happy to have cleaned up the mess in our attic and crawl space and assured that a new infestation is unlikely since all possible entry points have been patched up. In any case, they set traps in the attic and crawl space to make certain that we were rodent-free, and they provided a five-year guarantee to return at no cost if we detect any new rodent infestation. OVERALL WE WERE VERY SATISFIED WITH THE SERVICE FROM ATTIC PROS, INC, AND WE WOULD RECOMMEND THEM (IN FACT, WE ALREADY HAVE) TO ANYBODY NEEDING INSULATION REPLACEMENT AND/OR CLEANING UP FROM PESTS AND RODENTS."

Customers say: True professional

"Fantastic service, Mosh and employees dedicated to the complete eradication of all rodents. Traps, closing off access areas with steel mesh and sanitizing attic with a spray was worth the money. Most important was Mosh’s follow up 2 weeks later to make sure everything was all right. 10 star rating"

"We had a rodent infestation in our crawl space and insulation that had been installed upside down, a condition that can cause mold. I chose Atticare because they cleaned up the old insulation and rodent droppings, sealed entry points, sprayed to prevent mold, bacteria and viruses, installed insulation, and were clean. They cost more than other local insulation companies but I didn't have to hire a separate exterminator or worry about mold from the old insulation that was installed wrong. They arrived on time, answered questions and were very easy to work with. I would recommend them."

"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."

FAQs for spray foam insulation projects in Corte Madera, 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.
