"This is the second time I have used Gaona and they are professionals. They also have excellent customer service and give you personal attention to make sure the job is done timely and to your satisfaction. Francisco Jr, Mr Sanchez, JR and everyone else makes sure to keep the communication alive during the project. They also did my sheetrock, texture, tape and float and my interior and exterior painting on my new building. I highly recommend them!"

"I can't comment on the effectiveness of foam insulation yet but hopefully it will do a great job. This is the first time I ever had foam insulation so really excited. Logan worked in conditions that were very severe. My attic space was 129 degrees while he was installing our foam. Logan is a very hard worker and I would recommend him to anyone."

Drywall Insulation FAQs, answered by experts

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.

You can plaster over regular drywall, but it's essential to prepare the surface properly. Before plastering, the drywall should be clean, free of dust, and any loose or peeling paint should be removed. Applying a primer specifically designed for plastering can improve adhesion. Some professionals recommend applying a base coat of plaster or joint compound to create a better surface for the plaster to adhere to. Proper preparation ensures a smooth and durable plaster finish over regular drywall.

Drywall can get wet and dry out without sustaining permanent damage, but only if the water damage is minor. If you have a small leak and are quick to correct the issue and set up blower fans and dehumidifiers, your drywall should dry out. If the leak is persistent, the drywall becomes totally waterlogged, or mold begins forming on the drywall, you should remove and replace it.

There are a few ways to figure out if your walls are plaster or drywall, but the pushpin method is probably the easiest option. To try it, choose a part of your wall where you can insert a pushpin or thumbtack without leaving an obvious mark. If it goes in easily, you have drywall. But if the wall is tough to penetrate, that’s plaster.

You can usually tell if you have plaster or drywall by touch (plaster is harder, colder, and smoother than drywall) or by tapping on it (drywall sounds hollow, plaster does not). If you still cannot tell, peek under an outlet cover and check the cut edges. The rough edges show the composition of the wall. You will see either drywall (two paper sheets sandwiching gypsum material) or only plaster material (no paper sheets).
