Herberto and his son Brian were right on time, finished the project perfectly and a little bit ahead of schedule. I would definitely use them again for installing and repairing drywall! Price was reasonable as well. - ST
- Dean R.
Beto’s drywall did an awesome job, replacing drywall and baseboards, and they even matched the texture coat of the new drywall to existing drywall. Their work is high quality, and the entire crew is courteous. They cleaned up everything and I highly recommend them!!
- Gino L.
I had some offices built and had Luise drywall from start to finish and also had him paint my building inside as well as the completed offices, great to work with and was on time and worked clean !
- Clayton H.
The house only had about 2" of insulation in about half the attic. After the blown in insulation was done the house was instantly quieter, the temperatures throughout the house more consistent and the AC runs less. Very happy with the results.
- Cameron R.
These guys are great. We were in escrow on an investment property and short on time and needed to blow in all new insulation in the attic. They fit us in a day later and their price was better than anything we could find. Definitely our go-to guys for insulation now.
- Sheldon S.
The House Next Door Did My Insulation In the Attic, Foundation,Tankless Water Heater, Exterior Paint,Roofing, Reese Lights,as well my plumbing. The Workers Fast And Clean. There was a lot of communication with the contractors. I would definitely use the house next door for my future project.
- Marlene D.
. Plumbers were good.....but let me tell you the drywall guy was amazing. No dust, perfect match. In some areas you can not even tell there was a hole there. Cant say enough. Done in a week, plumbing, dry walling, and inspection. Goo experience.
- Nancy M.
2 ADI employees arrived on time and did an excellent job. I liked that they were honest with me before they started and said they may have to cut the drywall and that repair would not be included. They had to add the wiring to the ceiling and were able to do it through the attic access...

"I recently hired Ben for a remodel project at our home that involved removing a wall, and after getting multiple bids, his was the most competitive by far. His pricing was fair and transparent, andI chose him not just because of the cost, but because of the strong reviews and quality of work had seen from him. I'm happy to say his team exceeded expectations. During the project, some unforeseen issues were uncovered--things that many contractors would typically use as an excuse to dramatically increase costs. But Ben approached it with honesty and gave us a fair, reasonable assessment. No games, no surprise upcharges-just straightforward, high-quality work. The craftsmanship was excellent, and the entire job was completed with care and professionalism. I'm already planning to use Ben for future projects and will be referring him to my realtor, family, and coworkers. If you're considering home renovations or repairs, don't hesitate-I"ve done the research, and Ben is the best out there."

"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

FAQs for drywall insulation projects in Simi Valley, CA
On average, drywall installation costs $2,000, depending on the size, complexity, accessibility, and location of the job. The typical cost range is from about $400 to $6,000, which includes materials and labor. Additional cost factors include the thickness of the drywall, the shape and height of the room, and the level of finish. The level of finish ranges from only hanging the drywall to taping and mudding the seams between panels to painting the walls.
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
The cost to skim coat drywall is $1.15 to $1.35 per square foot. Most of the cost is labor, for the necessary skills to apply the skim coat with precision using high-quality tools. This is a job better left to the professionals for the best outcomes.
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
