Galveston: where the seawall faces one way and the water came from the other
Water damage restoration in Galveston, TX, starts with a question most mainland homeowners never ask: did the water come up from the ground, in from the bay, or down through the roof?
The seawall along the Gulf side is the island's best known defense, and it faced Hurricane Ike when the storm came ashore at the island early on September 13, 2008. But the National Hurricane Center's report on Ike describes how the surge pushed into Galveston Bay and flooded the city from the bay side, where there is no seawall, and much of the city took water.
That history is why so many island homes sit on pilings or raised foundations, and why a Galveston water damage call often involves salt water, sand and silt rather than a clean pipe leak. It also explains the paperwork: on the island, wind, flood and plumbing damage usually fall under different policies and different rules.
What Galveston homeowners usually need
Island water damage tends to come in two flavors. Storm water and surge are dirty, salty and widespread, and they reach the lowest level first: the ground floor enclosure under a raised house, the garage, ductwork and anything stored below the flood line. Inside jobs are more like anywhere else in greater Houston: a supply line under a sink, a water heater, an ice maker, an air conditioner drain pan, or a roof that let wind driven rain in. The pages below explain what a careful restoration company does for each.
Water Damage Restoration in Houston
The full job after a leak or flood: inspection, water removal, drying, cleaning and rebuilding, and how a restoration company works from the IICRC water categories.
Emergency Water Removal and Extraction
Standing water on the floor right now. What extraction equipment does, why speed matters in Houston humidity, and what to do safely before the company arrives.
Flood Damage Restoration
Rising water from a bayou, street or storm surge. Why floodwater is treated as contaminated, what gets removed, and how flood insurance differs from a homeowners policy.
Water Damage Repair
Putting the house back after it is dry: drywall, baseboards, flooring, cabinets and paint, and how repair estimates differ from drying estimates.
Mold Remediation in Houston
Mold after a leak or flood: containment, removal and clearance, the Texas licensing rules, and the protocol a licensed assessor writes first.
Mold Inspection and Mold Testing
Musty smells, hidden leaks and post-flood checks. What a licensed mold assessment consultant does, when air or surface samples help, and why the assessor and remediator are separate.
If a company tells you a ground floor enclosure or the materials in it need to come out, ask why. Salt water and silt behave differently from tap water, and the reason should be specific to what it measured and saw.
Galveston water cleanup when the water is salty
The ANSI/IICRC S500 standard, which most restoration companies follow, sorts water by how contaminated it is. Seawater and water that rose from outside are among its examples of Category 3, the most contaminated group, while a broken supply line is Category 1, clean water.
Why the category matters
Category 3 water generally means porous materials it soaked, such as carpet pad, insulation and the bottom of drywall, are removed rather than dried in place, and workers wear protective gear. A clean leak caught early is often dried in place.
Not every storm leak is the same
In March 2026, the S500 consensus body said water from weather events, including wind driven rain, is not automatically Category 3. The category depends on what the company finds at your house. Rain through a torn roof is not surge.
Water gets worse with time
The standard notes that clean water can degrade to gray or black water as it sits, especially in heat. On a warm island, a slow leak found days later may not be Category 1 anymore.
Ask for it in writing
Ask the company which category and class it assigned, what readings it took, and what it plans to remove. Keep that page for your insurer and for any permit file.
Wind, flood and plumbing: three different claims on the island
Galveston County is one of the first tier coastal counties in the Texas Windstorm Insurance Association's coverage area. TWIA says its policies cover direct damage from wind and hail only. They do not cover flooding or storm surge, and they do not cover fire or theft. Flood coverage has to come from a separate policy, such as one written through the National Flood Insurance Program, and a flood policy does not cover wind or hail damage to the structure. The two are designed to sit side by side.
TWIA also lists eligibility rules: you generally must have been turned down by at least one private insurer, the building must be certified as built to code, and some properties in V zones built or substantially changed after September 1, 2009 must show proof of flood insurance if it is available. A third layer is your homeowners policy. The Texas Department of Insurance says most homeowners policies cover sudden and accidental water damage, such as a burst pipe or a broken washer hose, but not gradual leaks and not floods.
What that means after a storm
A single storm can leave wind damage to the roof, rain damage in an upstairs bedroom and surge damage on the ground level of the same house. Photograph and video every area before anything is moved, and report the damage to each insurer that might be involved. Ask each one:
- Which parts of this damage does my policy consider covered, and which does it exclude?
- What is my deadline to report, and what proof do you need?
- Will you send an adjuster before drying starts, or should I protect the property now and document it?
- Does the policy pay anything toward permit or elevation costs if the house is found substantially damaged?
New flood policies through the NFIP generally have a 30 day waiting period, with some exceptions, so a policy bought when a storm is in the Gulf usually will not apply to it. The insurance guide explains flood versus water damage in more detail.
The 50 percent rule and Galveston repair permits
Before you rebuild, check with the city. The City of Galveston says all development in its floodplain requires a permit under its flood damage prevention ordinance. If the cost of repairs or improvements, labor and materials together, equals or exceeds 50 percent of the building's market value, the city treats it as substantial damage or substantial improvement. That triggers new construction standards, including a lowest floor at least 18 inches above the base flood elevation, the city's minimum design elevation.
The city says substantially damaged or improved homes need building permits and elevation certificates. For questions about your property, the city's flood page points to the Floodplain Administrator at 409-797-3814, and asks owners to call before any work on a structure in the floodplain. Raise the 50 percent question with the restoration company early, so its written estimate separates drying and cleanup from rebuilding.
Elevation certificate: a form, filled out by a surveyor or engineer, that records how high the lowest floor of a building sits compared with the base flood elevation on the flood map. Insurers and the city both use it.
Why Galveston homeowners call the line
Water from three directions
Surge from the bay side, wind driven rain through the roof and everyday plumbing leaks all happen here. One free call, any hour, gets your description to a local restoration company that takes island calls.
Salt water changes the job
Seawater is a Category 3 example in the IICRC standard. Describing it on the call lets the company you are connected with know what to expect before it arrives.
Separate wind and flood claims
TWIA covers wind and hail, not surge. A written estimate that separates each kind of damage helps when you talk to more than one insurer. The line itself never handles claims.
You pay the company, not the line
Calling is free. The independent company sets its own prices and you settle the bill with it. This site explains the TDLR mold license check before you hire.
Safe first steps on the island
Safety before anything else. If you smell gas, leave the house now and call 911 and your gas company's emergency line from outside. Never walk into standing water near outlets, cords or appliances; switch power off at the breaker only if you can reach the panel while standing on a dry floor, otherwise call your electric utility or an electrician. Stay out of surge water and sewage, and keep children and pets away. If it is safe to reach, close the main water shutoff.
Once everyone is safe, take photos and video, move photos and papers upstairs or to a dry spot, and call your insurers. If a storm is coming, follow evacuation orders first; water damage can wait, people cannot. The first 48 hours guide goes step by step, and why Houston floods covers the wider region's drainage and flood maps.
Mold is the slower problem. The EPA says wet materials dried within 24 to 48 hours usually will not grow mold, a guideline rather than a promise, and island humidity works against drying on its own.
Check the mold license first. In Texas, mold assessment and mold remediation are licensed by the Texas Department of Licensing and Regulation (TDLR). In most cases visible mold under 25 contiguous square feet can be cleaned by people without a license; larger jobs generally call for a licensed mold assessment consultant to write the remediation protocol and a separate licensed mold remediation contractor to do the work. Ask for both license numbers and look them up on the TDLR license search (opens in a new tab). The line does not check licenses for you.
