C-02 Insulation and Acoustic #: 1127373 EXP: 10/31/2026
"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"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."

"Charles Trujillo did a great job patiently explaining how he was going to meet the challenge of attaching drywall to my cinder block wall and then he and his son followed through, completing the drywall and painting in two days. The quote was higher than some, but I am confident the work will hold up and it is backed by a year's warranty. Moreover, the crew did touchup painting of the ceiling and at my request returned to push my bed to the exact spot where it previously stood so no carpet pressure marks were visible."

"He was very responsive and answered all my questions. The 2 guys worked efficiently and made sure all measurements were to my liking. The only reason why I gave 4 stars is because the next day I noticed an indent from where the frame and drywall met so probably just needed one more layer of plaster to even it out I’m not sure. I sent him a picture with my concern and he didn’t respond."

FAQs for drywall insulation projects in Norwalk, 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
