Drywall Repair Q&A

Drywall repair costs $300-$1,200 depending on the damage, with small jobs like patching a doorknob hole running $50-$150 and full wall replacement $500-$1,500. The pricing model: most pros charge $50-$150 per hole (including patching, taping, compound, sanding, and texture matching), or $2-$4 per square foot for larger damaged areas. Water damage is the expensive category: a stained ceiling patch runs $200-$500, but water-damaged drywall that needs cutting out and replacing runs $500-$1,500 including finding and fixing the leak source. Other common jobs: cracks at door frames and ceiling corners ($150-$400, and they often reappear if the underlying movement isn't addressed), large holes over 12 inches ($200-$500, needing a new piece of drywall and backing), and whole-wall replacement after major damage ($500-$1,500 plus painting $300-$800). Most repairs need 2-3 visits or days because compound layers must dry between coats. Paint matching is usually separate: $100-$300 to blend a patch into the surrounding wall.

Small drywall repairs are classic DIY projects — patching nail holes, small cracks, and doorknob dings takes an hour and $10-$30 in materials (spackle, putty knife, sandpaper). Medium repairs like fist-size holes are doable with a patch kit ($15-$25): the hole gets a mesh patch or a new piece of drywall screwed to backing, then joint compound in 2-3 coats with drying time between. The skills that separate DIY from professional results: feathering (blending compound edges so the patch doesn't create a bump), texture matching (matching knockdown, orange peel, or popcorn texture on the repaired area — hard to replicate by hand), and large-area flatness (a smooth, seamless finish over 4+ square feet takes genuine skill). Realistic assessment: holes under 6 inches are fine for DIY; holes over 12 inches, water damage, or ceiling repairs are worth the $200-$600 professional fee. If you DIY, expect the project to span 2-3 days (drying time), buy a texture spray can matching your wall type, and be prepared for the patch to show if you rush the feathering.

Recurring drywall cracks mean the cause is structural movement, not a finishing failure. The most common recurring cracks: above doorways (the door frame moves from settlement or seasonal humidity), at ceiling-wall corners (roof trusses expand and contract — truss uplift lifts the ceiling slightly and cracks the joint), and along wall seams (foundation settlement). Cosmetic patches over these cracks always fail because the underlying movement continues. The lasting fixes: for truss uplift, a special 'floating' corner detail that allows movement ($200-$500 professional work); for door-frame cracks, flexible caulk and backer rod instead of rigid compound ($50-$150); for foundation settlement, the real fix is structural (foundation piers $3,000-$10,000+) and the cracks will keep reappearing until then. Two clues that a crack is structural: it's wider than 1/8 inch, and it reopens within 6-12 months of patching. Cracks from temperature and humidity cycles (seasonal) can be minimized with flexible products designed for movement joints. If you've patched the same crack twice, stop patching and have a professional diagnose the movement source.

Repairing water-damaged drywall costs $200-$1,500 depending on the damage extent. Small stains with no structural damage: $200-$400 to cut out the stained section, patch, texture, and repaint (after fixing the leak — ceiling stains that keep growing indicate an active leak that must be addressed first). Moderate damage with sagging or bubbling: $400-$800 for a 4x4 ft section replacement. Large areas or multiple rooms: $800-$1,500+ for cutting out and replacing entire sections of wall or ceiling. The complicating factors that raise costs: the leak source must be found and fixed first (roof repair $300-$2,000, plumbing repair $200-$1,500 — depending on what's leaking); mold remediation is needed if the drywall stayed wet (mold testing $300-$800, remediation $500-$6,000); and insulation behind the drywall may need replacement if it got wet. Drywall that's been wet for more than 48 hours has likely lost structural integrity and should be cut out — drying it and patching only works for fresh, minor damage. Homeowners insurance often covers water damage repairs (minus deductible) if the cause is sudden and accidental.

A small drywall patch (doorknob hole, nail holes) takes a professional 1-2 hours total, but the project spans a day because compound drying time: the first coat takes 2-4 hours to dry, the second coat overnight. A multi-hole repair is a 1-2 day job: day one (patch and first coat), day two (second coat, sand, touch up, paint if included). Full wall replacement takes 2-3 days including taping, 3 coats of compound, sanding, and paint. Texture matching adds half a day (the texture must be applied to the patched area and dry before paint). DIY timelines are roughly double: compound coats need the same drying time but each coat takes longer to apply, and the sanding-feathering cycle usually requires rework. The drying-time constraint matters for scheduling: you can't rush compound with a hair dryer (it blisters), and painting over damp compound causes the paint to peel. If you're having the walls painted anyway, schedule the repair first and paint over everything — matching paint on a patch is the hardest part of making a repair invisible.
