What to look for in a water intrusion specialist

Water intrusion means water getting into a building where it shouldn't: through the roof, walls, windows, foundation or plumbing. The visible stain is often far from the actual entry point. A good specialist finds the source, not just the symptom.

Common entry points

• roofs, flashing, skylights and chimneys;
• windows and doors with failed seals or flashing;
• siding, stucco and masonry cracks;
• foundations, basement walls and window wells;
• hidden plumbing leaks inside walls or under floors.

How investigation usually works

Specialists typically combine a visual inspection with tools such as moisture meters and thermal imaging cameras to trace where moisture is spreading. In some cases they use controlled water testing to reproduce a leak. The goal is to confirm the source before recommending repairs.

What to look for

• A documented process. Ask how they will record moisture readings and findings, with photos and a written report.
• Source identification, not just cleanup. Drying a wall without fixing the entry point means the problem returns.
• Drying and mold awareness. Ask how they will dry affected materials and check for mold. The EPA advises drying water-damaged areas within 24 to 48 hours.
• Clear scope and pricing. Get a written estimate that separates investigation, drying and repair.
• Licensing and insurance. Requirements vary by state and city, so ask what applies to the work and request proof.

Questions to ask

1. How will you confirm where the water is coming in?
2. What tools and tests will you use?
3. Do you handle drying and repairs, or only the investigation?
4. Will I get a written report I can share with my insurer?
