What is different about a coastal surge cleanup?
A coastal surge brings sand, shell and debris, pushes against the outside of the building, and leaves the lower structure wet from several directions at once. The cleanup starts outside and works in, and it treats the silt as a material to remove, not only as water to dry.
Surge water leaves sediment behind. It settles into the cracks in the floor, the gaps under the baseboard and the openings in the subfloor, and it stays there after the water is gone. A cleanup that only dries the surface leaves that sediment in the building, where it holds moisture and makes the next wet season worse.
The water also comes from outside. Walls, doors and crawl-space vents can be forced open by the water, and the outside of the building can be damaged in ways that let rain in later. The crew notes the openings it finds, so the building can be closed up properly once it is dry.
How far above the ground does surge damage usually reach?
The height of the tide line is the best guide, and it is measured on the building rather than guessed. Materials below that line are assessed for removal, and materials above it are checked for wicking, which can carry moisture upward.
On the Panhandle coast, Michael's surge was reported at 9 to 14 feet above normal along parts of the coast, with the highest surge at Mexico Beach, according to NOAA's post-storm summary. That is a coastal figure. It does not describe the surge at any single house, and the tide line on each building is the only real measure of what happened there.
A crew marks the tide line on the walls and the framing as it works, so the removal and the drying are planned from the actual height of the water. Materials above the line can still hold water that wicked up, and that is measured, not assumed.
What moves the price of a coastal surge cleanup?
The price follows the height of the surge, how much of the building was under it, the amount of silt and debris, and how much structure has to be opened. No figure is given on this site. The scope and the price are explained and approved on site before work starts.
The amount of debris and silt is the first cost driver on a coastal job. A small amount on a hard floor is a short clean-up. A deep layer in a crawl space, or sand packed into a wall cavity, is a longer job, and it is priced after the crew has seen how far it goes.
The number of separate spaces matters too. A house with a garage, a raised floor and a main living area is three jobs with three sets of readings, not one. Each is measured and written up on its own, and the scope shows each part so you can follow it.
Does the cleanup include fences, decks and the yard?
The main cleanup covers the building and the structure under the water line. Fences, decks, sheds, landscaping and exterior finishes are outside the scope unless the job says otherwise, and they are noted in the write-up so they can be dealt with separately.
A crew will tell you about outside damage it sees, because that damage can let water back into the building. A torn door seal or a displaced vent is part of the house work. A fence or a shed is not, and it may be a separate claim.
Keep a record of the outside as well as the inside. Photograph the fences, the sheds and the yard before anything is moved, so the claim file shows what was there before the storm.
How do I know when a coastal building is dry enough to close?
The building is dry when the readings in the framing, the subfloor and the lower walls reach the dry target for each material. The crew reports the readings on each visit, and the last reading is the one that decides when the walls can be closed.
Coastal air is humid, so a building that looks dry can still hold moisture in the framing and the subfloor. A wall that is closed while it is still wet can grow mold behind the finish, and that is hard to find later.
Ask for the final readings in writing, along with the materials they were taken from. That record is what a contractor who closes the walls will need, and it is the clearest answer to whether the job is finished.
