Water damage repair
Repair is the second half of the job and the half people picture when they think about the cost. It is also the half that goes wrong when the first half was not finished properly.
The line between the two jobs
Everything up to and including drying is about stopping the loss. Repair starts after that, and it is ordinary building work: drywall, trim, flooring, paint. The reason they are discussed together is that the same company often quotes both, and the reason they should be read separately is that the quote usually prices them separately.
If you are comparing two numbers that look wildly different, this is the first place to look. One may be mitigation only; the other may include putting the room back.
What gets repaired, and what gets replaced
Drywall that got wet at the bottom of a wall is usually cut back and replaced rather than dried in place, because the paper facing holds water and wicks it upward. Trim often survives. Flooring depends almost entirely on construction: tile on a solid substrate is frequently fine, laminate and engineered boards that have swollen are not, and solid hardwood sits in between depending on how quickly it dried.
Insulation inside a wall or ceiling cavity is usually removed. It holds water, sits where there is no airflow, and is cheap relative to the cost of being wrong about it.
What it costs to put back
| What is repaired | Published range |
|---|---|
| Ceiling | $450–$1,600 |
| Drywall | $300–$850 |
| Floors | $200–$550 |
| Bathroom fixtures | $140–$800 |
| Roof | $400–$1,700 |
| Plumbing | $1,000–$4,000 |

Doing some of it yourself
The repair half is normal DIY territory for anyone who does that sort of thing. The part that is not is deciding when to start: that is a moisture reading in the material, compared against part of the building that never got wet, and it is the decision the whole repair rests on.
If the water was anything other than clean, the removal side is also not a DIY job. CDC's guidance on water from outdoors or from a sewer is to stay out of it, which puts that work in a different category entirely — see sewage cleanup.
Questions people ask
What is the difference between restoration and repair?
Restoration is the drying and the removal that stops the loss getting worse. Repair is replacing what came out and making the room look like a room again. They are different trades, often different companies, and almost always different lines on a quote.
Can I do the repair part myself?
Plenty of people do: patching drywall, replacing trim, repainting and laying new flooring are ordinary jobs. The part worth not doing yourself is deciding whether the material behind it is dry, because that decision is made with a meter and it is the one that determines whether the repair holds.
How long should I wait before repairing?
Until readings in the affected material match an unaffected part of the same building. Repairing over material that is still wet is the single most common way a job gets done twice, and the delay it saves is measured in days against a cost measured in thousands.
What does repair cost?
Published national figures put drywall at $300 to $850, floors at $200 to $550 and ceilings at $450 to $1,600. Those are repair only — the drying is priced separately, which is why two quotes can differ enormously while both being honest.
Does flooring always have to come out?
No, and the answer depends on the type. Tile on a solid substrate often survives; engineered and laminate floors that have swelled generally do not; solid hardwood sometimes recovers if it dried fast enough. What is underneath matters more than what is on top, because water gets under floating floors and stays there.
