How to Spot Water Damage Before You Buy a House

Buying a home is an exciting yet significant investment. However, hidden issues like water damage can turn your dream home into a nightmare. Recognizing signs of water damage...

Water damage is the expensive kind of surprise: it hides behind fresh paint and under new carpet, and it shows up on your repair bill after you own the place. Take a slow walk through any house you are considering with these eight checks in mind. Do you know what to look for before you make the offer?

Walls and ceilings

Discoloration, peeling paint and lifting wallpaper all point at moisture behind the surface. Bubbling or cracking paint means something wet has been pushing at it. A sagging or warped ceiling suggests a roof leak or plumbing above it, and neither improves on its own.

Floors

Warped or buckling boards, particularly in bathrooms, kitchens and basements, are a classic sign of water. Press on suspicious areas: soft or squishy spots mean the subfloor has been wet for a long time.

Windows and doors

Look for water stains or mold around the frames. Windows and doors that are hard to open or close may have swollen frames, which is moisture doing its work.

The basement

Basements flood and leak. Water stains on the walls, especially low down near the floor, are the giveaway, along with a musty smell or anything visible growing.

Roof and gutters

Missing or damaged shingles, and gutters full of debris or showing signs of overflow, both let water into the house where you cannot see it arrive.

Attic

Check for water stains, mold and a musty smell, and poke at the insulation for dampness. Wet insulation means the roof has been letting go for a while.

Plumbing

Look under sinks, around toilets and behind appliances for active leaks. Water stains or warped cabinetry under a sink mean a leak has been there before, possibly more than once.

Outside

The ground should slope away from the house so water does not pool against the foundation. On exterior walls, look for efflorescence, that white chalky residue, and for cracks.

Bring in someone with instruments

A qualified home inspector can find hidden moisture with tools you do not own. In areas that flood or run humid, add mold testing to the inspection. Finding it before you sign costs you an afternoon; finding it after costs you a renovation.
