Average cost for drywall installation — San Francisco, CA

For a small hole in drywall, the most common method is using a self-adhesive mesh patch or a California patch. For a mesh patch, simply apply it over the hole, ensuring it adheres well. Then, apply multiple thin coats of joint compound over the patch, feathering the edges to blend with the surrounding wall. For a California patch, you cut a piece of drywall larger than the hole, score the back to remove the gypsum, leaving the paper intact, and then embed the paper edges into compound around the hole. Both require sanding between coats.

Drywall tape bubbles typically happen when not enough joint compound is applied beneath the tape, or when air gets trapped during application. As the compound dries, these air pockets create raised areas. The fix involves carefully slitting the bubble with a utility knife, ensuring the tape is flat against the wall. Then, apply a thin layer of joint compound over the area, feathering the edges. After it dries, sand smooth. Multiple thin coats are often needed to fully conceal the repair.

Greenboard drywall, known for its moisture resistance, is an excellent choice for areas prone to humidity, like bathrooms and kitchens in San Francisco homes. It helps prevent mold and mildew growth. However, it's not typically used for areas with direct water exposure, such as inside a shower stall; in those cases, cement board or a specialized waterproofing system is needed. For standard walls and ceilings in damp environments, greenboard is a reliable option.

Level 5 drywall finish is the highest quality finish, involving a final skim coat of joint compound applied over the entire drywall surface. This creates an exceptionally smooth and uniform surface, free from imperfections. It's particularly important for areas with critical lighting, such as in San Francisco homes with large windows or where high-gloss paints will be used. This finish provides a flawless canvas for paint, ensuring a professional and aesthetically pleasing result.
