"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."

"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"

"Rafael and his company are great people to work with. Their in-depth estimate and assessment of the attic is unparalleled, not to mention competitive. They were very flexible with accommodating our needs on our schedule. Very responsive Manager too, would reply to my calls and text almost immediately. I really appreciate how hard working and efficient these guys are. I had other workers doing work on our house at the same time and they were also impressed at how clean they left the attic before installing the new insulation. Rafael values your business and his work and attitude definitely demonstrate it. Call them you won't regret it."

"I spent thousands of dollars on a popular pest control company and three months later the problem was worse! I canceled the year long contract they put me on and contacted California Attic and build. Ben and Dan came out and professionally assessed my situation and guaranteed the work they would do. Within a few days the problem was solved. I can finally sleep at night!"

Drywall Insulation FAQs, answered by experts

Yes, you can use drywall repair techniques for some types of plaster damage. Tiny holes and small cracks in plaster can be patched in similar ways to drywall. You apply the necessary compound to fill the hole, wait for it to dry, then sand it down. For larger damage, like water damage or mold, you need to use plaster-specific techniques and materials.

Drywalling a garage is a smart decision if you want to protect your garage from fires, moisture damage, and exterior noise. Most garages have flammable supplies that could result in serious damage in the off chance of an accident. Drywall is fire resistant, helping to prevent fires from spreading. Not to mention, drywall can improve the appearance of a dingy, old garage.

The person’s skill will affect how many drywall sheets they can hang in one day. Some people can hang 10 or more sheets in a day, while others may only hang six or seven sheets. It also depends on the framing complexity since custom cutting and fitting the drywall can prolong the process.

Plastering lasts for around 15 to 20 years without needing repairs or maintenance in most cases, and with proper upkeep, plastering can last a lifetime—sometimes more than 100 years. Plaster repair costs between $1 and $3 per square foot, and you may need these services once every 15 to 20 years or so unless you have a harsh climate where humidity changes are a constant issue. You can also opt to skim-coat plaster for between $0.90 and $1.30 per square foot, which may serve you better in the long run.

You should stagger drywall sheets to help prevent cracking. The joints between drywall sheets are the weak spots, so if you install drywall with seams aligned, you’ll create weak lines that run across the length of the wall and extend from floor to ceiling. But when you stagger drywall, the solid sections of panels will support the joints. This can prevent seams from cracking or separating due to fluctuating temperature and humidity, vibrations from movement inside the home, and gravity.
