"The owner of the company Jason Taylor spent time in my attic before we contracted with them so he could give me good and correct information. He also participated in the work of shooting in the insulation. He was very hands-on. Donâ t usually expect this attention from the owner/boss Was very pleased."

"This company installed two whirlybird wind turbine on the roof. During the installation, one roof rafter was cut halfway with a saw blade. I thought the insulation process itself is excellent and am very happy with the result."

"Yes. Billy said everyone was great on install date. Omar was helpful and communicated effectively. Team worked well together and were efficient. Team was respectful of our property and cleaned up after work done. All of the team members being available was excellent to get install in one day. We hopefully will enjoy the benefits of the insulation and all went as anticipated with install. Very glad we had it done. Leo was excellent with pre install quote and arranging for install. We got a few quotes . We paid highest quote to have the work done quickly which met our needs. Thank you for the excellent service"

"Explained what was needed to be done. Arrived on time. Fast and efficient. removed all old insulation in attic-, sanitized and installed new insulation."

"Rafael and the Attic Advisor team were great! Rafael came out to do the free inspection and give us a quote. He was on time, friendly and very knowledgeable about the issues in our attic and what could be done to resolve them. The assessment and estimate were very in-depth, and the price was very reasonable and fair (compared to quotes I got from other companies for the same work). Even before committing to the project, Rafael was very responsive and would take time answer any question I had about the project. The project in my attic called for removing the old insulation, sanitizing, sealing to keep critters and rodents out, replacing old air ducts and installing new insulation. On the day of the project, the Attic Advisor crew was on time, hard working and extremely professional. They were very efficient and thorough, with even the smallest parts of the job, and if I had any questions during the process, they were very polite and happy to answer. I appreciated Attic Advisor’s thorough and complete work. I would highly recommend."

"California Attic & Build was fantastic! The team was professional on time and left everything spotless. They explained the process clearly and showed before and after photos. My home already feels more comfortable. Highly recommended for insulation, cleanup, and rodent proofing!"

"We just had attic insulation blown in over our garage and a little extra over the living areas. Nice people and good work!"

"Really well organized company they are amazing I will definitely recommend them nice work guys you guys made my family very happy now the property will be in better conditions due to your service thanks ?"

"The crew was on time, worked hard and efficiently, and cleaned up the work site beautifully after they were done. The subsequent patching, stucco replacement, and painting were so superb one would never know the entirety of the house had been drilled into in dozens of places. As for the insulation product itself, I was able to feel the positive effects of the insulation almost immediately. Happy to recommend Guardian for wall insulation work."

"After calling to request an energy audit and enhanced attic insulation, a representative came out to survey the site and prepare a proposal to replace heating ducts in the attic with R6 ducts, seal the attic from the house, and add 14? blown-in fiber insulation on top of the existing 8? of fiberglass insulation. 
Then a technician came out to do a safety inspection of the heating system, hot water system, fireplace, gas appliances, ventilation, ducting, etc. He completed a series of tests to measure how well the house was sealed before any work was done. He took pictures of everything.
Then a team came out and replaced the ducts, sealed the attic, built dams around the bathroom ventilation fan and the whole house fan, installed channels for the eave vents, and prepared to install new insulation. One of the techs accidentally miss-stepped and cracked the ceiling drywall (see: What surprises come up during the course of the work?), which prevented them from finishing the insulation install until after the ceiling was repaired, which they would do at no cost to me. 
A drywall tech came out to repair the ceiling and resurface the popcorn ceiling.
The install team came back out to complete the insulation install. They blew-in another 14 to 16 inches of fiber insulation on top of the ceiling joists pre-existing fiberglass insulation. They took pictures of everything.
The original technician returned to repeat the seal tests and take more photos. The test results, before and after, and all the photos would be submitted for a state energy efficiency program rebate.
I called about a month later to check on the status of the rebate, and was told that the state requested that the ventilation fan dam be upgraded. A technician returned to complete the upgrade and take additional photos to submit to the rebate program.
I received a $1300 rebate from a state energy efficiency program, reducing the cost to $700 to me."
