Why does storm water keep causing damage for days after the rain stops?
Storm water is slow to leave a structure once it is inside the walls and floors. It soaks into materials and wicks upward, so the damage keeps developing after the surface dries. Mold can start in the cavities that stay damp, which is why the drying has to continue until the readings confirm it.
Hurricane rain often falls for many hours, and the water in the ground stays high for days after the rain ends. That keeps the subfloor, the crawl space and the lower walls wet, and it slows the rate at which a home can release moisture to the air. A house can look dry in a week and still hold water in its framing.
The safe approach is to measure rather than assume. A crew that keeps taking readings can show when a room has truly dried, and a homeowner can see the same numbers. This matters most in the cavities behind walls and under floors, where the surface never shows what is happening.
What was different about the 2016 storm floods in Suffolk?
The 2016 floods in Suffolk included homes on Gates Road with water more than six feet deep, and a creek downtown that crossed a road and swept a car away. The storm showed that water could move through the city from several directions at once.
The Hampton Roads area felt more impact from Matthew than the forecast had indicated. Storm damage in the region was not limited to wind, and water was a large part of the cleanup that followed.
For a cleanup company, the lesson is that the forecast can under-count the water. A plan built around a rainfall number alone may miss the ground that is already saturated, the drain that is backing up or the creek that has come out of its banks. Readings in each room are the more reliable guide.
Should I open the walls myself after a hurricane flood?
No. Opening walls without measuring can spread contamination, remove material that could have dried in place, and leave the cavity exposed to new moisture. A technician decides where to open and what to take out, and photographs the cavity before anything is cut.
Homeowners often want to start tearing out wet drywall at once, because it feels like progress. A cut in the wrong place can release dust and debris into rooms that were otherwise clean, and it can expose insulation to air that is still humid, which encourages growth.
If you have already opened a wall, leave the opening as it is, photograph it, and tell the technician when they arrive. Keep the material that came out in a labeled place, because the crew may want to see it when the job is reviewed with your insurer.
How do I know when storm-flooded materials are dry enough?
A material is dry when its moisture reading falls to a target level set by the technician for that material and that room, and it stays there on repeated checks. Surface feel, a fan running and a clear smell are not reliable signs of dryness on their own.
The target is set by comparing a wet area with a dry area of the same material, so the crew knows what a dry reading looks like in the building. Wood, drywall, plaster and concrete each behave differently, and the target reflects that. Readings are written down with a date and location.
Drying usually continues until several consecutive readings hold at the target, and then the equipment is removed. The technician should be able to show you the log, including the first reading and the last one, so you can see the change for yourself.
What should a homeowner do with the photographs and records for an insurance claim?
Keep every photograph, every moisture log, every receipt and every written scope. The insurer will ask what was damaged, when, and what was done about it, and clear records make the claim easier to settle. The Virginia Bureau of Insurance handles homeowner complaints if a claim stalls.
Photograph the damage before anything is moved, and again after each stage of the work. Keep a simple diary of what you saw and when, including the time the water came in, the time it started to drop and the time the crew arrived. These notes are often more useful than the technical report alone.
If a claim is slow or denied, try to resolve the problem with the company or agent first. If that fails, the Virginia Bureau of Insurance, part of the State Corporation Commission, accepts homeowner complaints and can ask the company for its position. Whether a given loss is covered depends on your own policy.
