What affects the price

When you get a quote for drywall work, the final number depends on a few specific things. The size of the area matters, but the condition of your existing walls is just as important. If there is significant water damage, mold, or old layers that need removal, that adds labor time. Ceiling height and access also play a role, as harder-to-reach spots require extra equipment. The type of finish you want—smooth versus textured—changes the material needs and hours spent sanding. Every space is unique, so exact pricing confirmed free on the call.

About this service

Sanding is the mechanical process of smoothing down dried joint compound to ensure the wall is perfectly flat. You need to do this between coats of mud and again before you prime the surface. The goal is to remove high spots and ridges without sanding through the tape or paper facing of the board. Because it creates a lot of fine dust, it is important to use the right grit paper and, if possible, tools that capture dust as you work.

Frequently asked in St. Louis

What's the best way to use a drywall pole sander?

A drywall pole sander is used to sand large areas of drywall, especially ceilings and high walls in St. Louis. The pole extends your reach, making the sanding process faster and more efficient.

While not essential for small repairs, it can significantly reduce the time and effort for bigger jobs. Professionals often use them for efficiency.

How do I patch a hole in drywall?

Patching a hole in drywall typically involves cleaning up the edges of the damage. Then, a piece of drywall is cut to fit the hole and secured in place. Joint compound, or 'mud,' is applied over the seams and any screw heads. Multiple thin coats are applied, with sanding in between, until the patch is smooth and flush with the surrounding wall. The goal is to make the repair invisible once painted. Professionals do this efficiently.

What kind of drywall mud should I use?

The type of drywall mud you use depends on the job. All-purpose joint compound is good for general patching and finishing. Lightweight spackle is excellent for small holes and dries fast. For larger repairs or multiple coats, pre-mixed joint compound is convenient. Some pros prefer setting-type compounds that harden chemically and are stronger. The right mud makes sanding and finishing much easier. Professionals know which to use.

Is mold resistant drywall worth it?

Mold resistant drywall is a good investment for areas in St. Louis homes prone to moisture, like bathrooms or basements. It's treated to inhibit mold and mildew growth, which can be a serious issue. While it's more expensive than standard drywall, it offers better protection against moisture-related problems. This can save you money on future repairs and health concerns. It’s a smart choice for specific environments.

What is a drywall patch?

A drywall patch is a piece of material used to cover holes or damaged areas in drywall. These can be pre-made metal or mesh patches that are self-adhesive, or simply a piece of new drywall cut to fit the damaged area. The patch is then covered with joint compound and sanded smooth to blend with the wall. It's a common and effective solution for repairing smaller holes and cracks. Professionals use them for quick fixes.

What are drywall panels?

Drywall panels, also commonly called drywall sheets, are large, flat pieces made from gypsum plaster pressed between two layers of heavy paper. They are the standard material used to cover interior walls and ceilings in homes and buildings. In St. Louis, these panels come in standard sizes like 4x8 or 4x12 feet. They are installed by cutting them to fit the space and then taping and mudding the seams. This creates a smooth, continuous surface ready for painting.
