"Extremely satisfied with AJM Construction. They are very professional and good at explaining what will be done, how it will be done and when it will be finished. Everything was clearly spelled out in written estimate and the contract. They were on time and did a great job covering furniture and cleaning up afterwards. We have no reservations giving them them a 5 rating and highly recommending them for any drywall work."

Drywall FAQs, answered by experts

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

The cost to install drywall is between $1.50 and $3 per square foot, while shiplap installation costs between $2 and $7 on average. In most applications, shiplap installations cost more than that of putting in drywall. However, several ways exist to reduce shiplap prices, especially for small locations or accent walls, which can keep the total cost of shiplap competitive with that of drywall.

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.

Drywall texture refers to the techniques used on the surface of drywall to create a pleasing visual or tactile effect. Depending on your desired outcome, drywall texture can range from incredibly subtle to a focal point of a room. Textures play a significant role in interior design and are an excellent and relatively cost-effective way to change the feeling of a room.

In most cases, no, you won’t need a permit to replace drywall. If you’re changing the floorplan of your home by adding or removing walls during the drywall project, then you might need a permit, but replacement or repairs usually doesn’t require a permit. Your drywall professional should be able to confirm whether or not a permit is required for your project. If it is, it’s likely to add between $50 and $150 to your total cost. Keep in mind that you will need permits if you plan to install new electrical wiring or plumbing lines behind your new drywall.
