Drywall & Ceiling Water Damage Cost

Estimate the cost to cut out and replace water-damaged drywall or ceiling from the linear feet involved, your price per foot, the paint and finish, and a contingency buffer.

Planning estimate: this is a planning estimate from the numbers you enter — not a bid, a contract or an insurance valuation. Restoration pricing depends on category/class, materials, access and local labor. Get itemized written quotes from licensed, insured, IICRC-certified restoration contractors before you commit.

Replacing 40 linear ft of water-damaged drywall or ceiling at $25.00/ft plus $200.00 of paint is about $1,320.00 with a 10% buffer. A common repair is a 2–4 ft flood cut above the water line. Enter your quoted price — a planning estimate, not a bid.

When water wicks up a wall or drops through a ceiling, the standard repair is a flood cut: the drywall is cut horizontally a set distance above the water line, the wet material and insulation are removed so the cavity can dry, and new drywall is hung, taped, mudded and painted. Pricing this by the linear foot of the run — plus a separate paint and finish figure — tracks the way most contractors quote it.

Formula

total = (linear_ft × price_per_ft + paint_cost) × (1 + contingency%)

Worked example

40 linear ft at $25/ft plus $200 of paint and a 10% contingency:

(40 × $25 + $200) × 1.10 = ($1,000 + $200) × 1.10 = $1,320

A typical flood cut is 2–4 ft above the water line; higher cuts or a full ceiling replacement raise the linear footage and the finish work.

What the per-foot rate covers

The per-linear-foot rate usually bundles the demo, the new board, tape and joint compound, and sanding — but confirm with your contractor whether texture matching, insulation replacement and the paint are inside the rate or separate. Painting a patch almost never matches the surrounding wall, so many quotes paint the full wall corner to corner; that is why paint is a separate input here.

This estimates the drywall and ceiling repair only. The drying that must happen first is a separate line (see the structural drying tool), and fixing the leak that caused the damage is a separate trade.

Frequently asked questions

What is a flood cut?
A flood cut removes drywall to a set height (commonly 2–4 ft) above the water line so the wall cavity and insulation can be inspected, dried and replaced. It is the standard repair for water that wicked up a wall.
How much does it cost to replace water-damaged drywall?
Price it by the linear foot of the run for cut, replace and finish, then add paint. Enter the rate from your own quote — a 40 ft run at $25/ft with $200 of paint and a 10% buffer is about $1,320.
Is drying included?
No. The cavity must be dried before new board goes up — that is a separate structural drying line. This tool estimates the drywall and ceiling repair itself.
Why is paint a separate figure?
A patch rarely matches the existing paint, so contractors often repaint the full wall. Keeping paint separate lets you match whatever your quote assumes.
