"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"

Drywall Insulation FAQs, answered by experts

Drywall is safe to cut as long as you follow proper procedures, such as wearing personal protective equipment and using the right tools to score and cut the drywall. When cutting new drywall, it can release dust with silica and other compounds that could pose health risks. Leave cutting drywall to the pros, or wear a high-quality respiratory mask, goggles, and other PPE when handling drywall.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

Plaster is a beautiful finish but is labor-intensive to install and remove. It’s vulnerable to cracking and more sensitive to moisture variance than drywall. Installing plaster on a new wall is an expensive process that can take days to weeks, depending on the scope. Removing a plaster wall can also be quite expensive and time-consuming.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

Whether you apply the drywall mesh before or after drywall mud depends on the type of patch it is. For self-adhesive patches, you’ll put the patch down first and then coat it with mud. Mesh patches that are not self-adhesive will require you to put mud down first and then press the mesh into it, followed by additional coats of mud.
