Drywall repair includes fixing damaged walls and ceilings—ranging from small nail holes and dents to large holes and water damage. The process typically involves assessing the damage, patching or replacing the drywall, taping, mudding, sanding, and texturing.
Drywall repair is the process of fixing damage to interior wall and ceiling surfaces. It involves patching holes, cracks, or dents using joint compound (mud), mesh tape, or new drywall sections, followed by sanding, texturing, and painting for a seamless, unblemished finish.
The average cost to repair drywall is $609 nationally, with most jobs falling between $295–$925. Small holes cost $50–$150, medium holes $150–$400, ceiling repairs $250–$1,400, and water damage $500–$2,500+. Small projects (under 10 sq ft): $75–$100 per square foot.
To repair drywall, the materials you need depend on the size of the damage. For small dings and nail holes, you just need spackle, a putty knife, and fine-grit sandpaper. For larger holes, you will also need drywall joint compound, mesh or paper tape, a drywall patch, and wood scraps for backing.
8 Common Mistakes to Avoid in DIY Drywall Repair
Some drywall finishers add a small amount of dish soap (like Dawn) to drywall mud as a workability hack. They do this to act as a surfactant, which reduces the surface tension of the mud.
Common Signs of a Bad Drywall Job
Visible seams or joint lines: You shouldn't be able to see where one drywall sheet ends and the next begins. If seams are showing through paint or primer, it likely means the taping and mudding were rushed or done unevenly. Uneven corners: Corners should be crisp and consistent.
Two common mistakes made during drywalling are improper joint compound application (such as applying it too thickly or not feathering the edges), and failing to stagger the seams across different studs, which weakens the wall and increases the risk of cracking.
Lydia begins a short series about patching drywall using different methods. This week involves patching drywall in an area without a stud. She screws 2x4 cutoffs behind the patch for a strong backing to accept the new drywall. Afterward, the area is ready for mesh tape and joint compound.
Neither tape is universally "better"; they both excel in different situations. Paper tape is generally stronger and more crack-resistant, making it ideal for high-stress areas and corners. Mesh tape is easier to use, self-adhesive, and moisture-resistant, making it perfect for quick DIY patches and bathrooms.
You can DIY small fixes like nail holes or tiny dents. But if you're dealing with structural issues, moisture damage, or ceiling cracks, it's smart to hire a professional. A trained handyman can help you get the most out of your drywall repair cost—for both the look and the lifespan of the repair.
There is no functional difference. Drywall is the generic term for the building material used to make interior walls and ceilings. Sheetrock is a highly popular, trademarked brand of drywall manufactured by the USG Corporation.
Small Repairs: Minor repairs, such as fixing small holes or cracks, typically cost between $100 and $300. Medium Repairs: Moderate repairs, such as patching larger holes or replacing small sections of drywall, can range from $300 to $800.
Drywall alternatives like plywood, plaster, and shiplap provide options for those seeking unique aesthetics or improved functionality in wall finishes. While drywall is affordable, easy to repair, and fire-resistant, these materials offer benefits that might better suit specific needs.
Before choosing mesh tape, there are a few disadvantages to consider. Mesh tape is not as strong as paper tape, and it's more likely to crack over time. Another concern is cost—mesh tape is more expensive than paper. This can impact your overall budget, especially for larger areas.
Stronger: While fiberglass may seem like the tougher material, paper tape's inelastic nature makes it a stronger choice for seaming sheets of drywall together. Easier to use in corners: Because of the middle crease, paper tape is easy to fold into inside corners.
Avoiding Common Drywall Plastering and Taping Mistakes for a Professional Finish
Technically, there is no maximum limit to how large of a drywall hole you can patch; if the hole is wider than 6 to 8 inches, you simply cut out the damaged section and screw a brand-new drywall panel into the wall studs.
Drywall sheets are heavy, and screwing into every stud ensures a more secure attachment, minimizing the risk of sagging or cracking over time.
Spackle is generally better for minor repairs. Joint compound, also called drywall mud or drywall compound, performs better when filling larger holes and cracks. Professionals also use joint compounds to embed drywall tape and reinforce the seams between drywall sheets.
Some people add a small amount of dish soap to drywall mud to reduce surface tension, which helps release air bubbles and create a smoother, more even finish, especially when applying the final "skim coat"; however, this practice is not recommended by professionals as it can potentially weaken the adhesion of the mud ...
Hanging drywall horizontally (often called "hanging the board") is the industry standard for walls, while hanging vertically is generally discouraged. Horizontal installation provides superior structural integrity and wall strength, creates significantly flatter and less visible seams, and is much easier for the taper to mud and finish.
