"I recently installed a 2 ton mini split AC in my garage and wanted to insulate the enclosed peaked roof attic area of about 550 sqft. I was going to do it myself with the HD blow in insulation and rental blower but decided to get a few quotes. East Valley was only a few hundred dollars more than doing it myself. Communication was great, price was great, the two-person crew showed up on time with a 1/2-hour courtesy call beforehand, when they arrived, they verified the project and square footage I gave them, they laid down a plastic sheet on the driveway to protect the drive, parked their box van and went to work, took about 45 minutes beginning to finish. Cleaned up and left- the crew was awesome and super friendly, polite and courteous. I would recommend East Valley Insulation to anyone"

"So far very good. Itâ s just completed hopefully this will make a difference. Feel good about having the old insulation removed after 38 years. Old insulation was breaking down like sawdust. Attic is clean now no critters or bugs to worry about. Everyone was professional & efficient. Ask again in one year for an update on performance & customer service if needed."

"The two man crew arrived right on the designated time, explained what they would do and prepped for spraying the insulation. They showed me before and after pictures. Cleaned up after themselves before leaving."

"Thermal Advantage did a great job insulating the masonry walls on my home. His crew was on time, answered all my questions, and now the difference in room temperature is noticeable. Well worth the reasonable price as I am seeing savings on my utility bill."

Drywall Insulation FAQs, answered by experts

Costs depend on damage size, labor rates, and whether additional services like painting are required.

You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.

Water-damaged drywall should almost always be replaced. Not only does it look bad, it’s a breeding ground for toxic mold. Even if you think the area is dry and there’s no active leak, the only way to be sure is to cut out the damaged area and see for yourself.

You should always hang drywall from the top down. Starting at the top makes it easier to create a straight, tight line between the ceiling and the wall. Any gaps that occur will be at the bottom, where they are easier to manage. You can either cut the bottom piece of drywall to fit the remaining space or cover the gap with baseboard trim. Additionally, starting at the top is physically easier, as you won't have to fit the top sheet into a tight space between the lower sheet and the ceiling, or try to balance the upper sheets on the lower ones while securing them.

Most repairs take 1-3 days, depending on drying times for joint compound and paint touch-ups.
