Water damage risk rises during home transitions. Buyers should look for past leaks and moisture during inspections; sellers should fix and document repairs; renovations can introduce new leaks at plumbing connections and shower pans; new construction materials can hold moisture; and vacant homes can leak for days unnoticed. A moisture check at each stage catches problems early.
- Ask about past water damage and repairs
- Test new plumbing work before closing walls
- Vacant homes need someone checking them
- Know the shut-off on move-in day

Fairfax County has an active housing market, and many homes change hands, get remodeled or sit empty between owners. Each of those moments has specific water risks — and specific chances to catch problems before they grow.
This guide is general information, not legal or real-estate advice; ask your agent or attorney about disclosure obligations.
01
What Should Buyers Look for?
- Ceiling and wall stains, especially below bathrooms
- Fresh paint in only one spot of a ceiling
- Musty basement odors and efflorescence on walls
- Warped or newly replaced flooring in one area
- Water heater age and condition, sump pump presence and condition
- Gutters, downspouts and grading that slope toward the house
A moisture meter check during the inspection can confirm whether a stain is old and dry or still active.
02
What Should Sellers Do About Past Water Damage?
Fix the cause, dry and repair the damage, and keep records — invoices, photos and moisture readings. Disclosure requirements vary, so ask your agent or attorney what applies to your sale.
03
Why Do Leaks Happen After Renovations?
- New supply and drain connections that were not pressure-tested
- Shower pans and tile installations that were not flood-tested
- Dishwasher, ice maker and washer hookups disturbed during the work
- Nails or screws driven into hidden pipes
Ask your contractor to test new plumbing and showers before walls and floors are closed.

Moving Into a New Home: First-Week Checklist
- Find and label the main water shut-off
- Check the water heater's age and drain pan
- Test the sump pump if there is one
- Look under every sink
- Replace rubber washer hoses with braided lines
- Make sure downspouts discharge away from the foundation
05
Vacant Homes and New Construction
Vacant homes can leak for days before anyone notices, especially in winter; keep the heat on and arrange regular checks. New construction materials such as framing and concrete can hold moisture, and settling soil can change drainage around a new foundation in the first years.

Frequently asked questions
Can a home inspection find hidden water damage?
An inspection may spot signs such as stains, odors or high moisture readings, but it cannot see inside every wall. A dedicated moisture inspection can follow up on anything suspicious.
