How do I know how wet my house really is?
A pinless moisture meter reads the surface of a wall or floor, a probe meter reads deeper, and a thermal camera shows cool damp patches without opening anything. Used together they map the water, because the damp area behind drywall is routinely larger than the stain you can see.
Wet materials hide in places the eye does not check: the bottom plate of a wall, the insulation inside it, the subfloor under vinyl, the back of a cabinet. A technician walks the whole level, then the rooms around it, and marks the edge of the damp area where readings drop back to normal.
That map is the basis for the equipment plan and the written scope. It is also the record you can keep for the insurer, with photos taken before anything moves, and it is the baseline each later reading is compared against.
How fast does the clock run?
Mold needs moisture and time, and the EPA's guidance is to dry water-damaged materials within 24 to 48 hours. Hot, humid mid-Atlantic summers speed that clock, while a cold basement in January slows it. Either way, extraction and drying equipment should start as early as a crew can be dispatched.
Prince George's County summers are humid, and July is the wettest month at roughly 4.6 to 5 inches of rain, so damp materials do not dry by themselves in a closed house. In winter the pace changes but the principle does not: wet framing and insulation stay wet until air movement and dehumidifiers remove the moisture.
Phones here are answered 24/7 and a crew is dispatched as fast as one is available. After a regional storm many people call at once, and no one can promise an arrival time. What you can do is shut off the water, lift valuables off wet floors and take photos while you wait.
- Shut off the supply valve if a pipe or appliance is the cause
- Keep out of any room where water reaches outlets, cords or the panel
- Photograph the water level and every wet item before moving anything
- Open closet and cabinet doors so air can reach the walls
What does restoration not cover?
Restoration crews extract, dry, clean and sometimes tear out wet material. They do not repair the broken pipe, replace a water heater or reroof a house. A licensed plumber or a roofer handles those, and rebuilding drywall, flooring and cabinets is its own project, quoted after the structure is dry.
In Maryland, home improvement work on a residence generally calls for a contractor holding a Maryland Home Improvement Commission licence. Whether extraction and drying on their own fall under that rule is not something this page can settle, so ask any contractor for its MHIC licence number and check it on the state lookup whenever repairs or rebuilding are part of the job.
In Prince George's and Montgomery counties, plumbers are expected to be registered with WSSC Water. Ask for that registration too when a plumber is involved in a sewer or water-service repair.
Who decides what gets torn out?
The readings and the water category decide, together with you. Materials that read dry or can be dried in place stay, and materials that touched sewage, or that stayed soaked too long, generally come out. A good crew shows you the meter reading and explains why before cutting anything.
Greenbelt's original homes, for example, are concrete block, and the older houses in Hyattsville often have plaster rather than drywall. Both dry differently from a 1990s subdivision wall, and a crew that knows the difference will talk about drying time before talking about demolition.
Take photos of anything removed, and keep the list. Your insurer, not this website, decides what a policy pays, but a clear record of what was wet and why it left the house makes that conversation easier.
