Quick answer
Alvin's median home was built in 1985, about 21 percent of its housing comes from the 1970s, and mobile homes account for about 13 percent. In houses that age, slow leaks from showers, tub surrounds and water heaters are common, so we read the wall and floor around them before cutting anything.
How Alvin's 1970s and 1980s houses take on water
Alvin's housing runs older than League City's. The median Alvin home was built in 1985, about 21 percent went up in the 1970s, and mobile homes make up about 13 percent of the housing. A house that age has often had updates such as new flooring, a remodeled bath or a replacement water heater, all sitting on original framing and plumbing.
That layering is why bathroom leaks matter here. Tile showers from that era were often built over a mortar bed and a liner, and when the liner or grout fails, water seeps into the wall and subfloor slowly. Nothing drips. The first signs are loose tile, a darkened baseboard or a musty smell in the hall.
In Alvin's mobile homes, we check closet floors under water heaters and washers first, since the decking there takes the brunt of a slow drip. In every kind of house we take readings before removal, because slow water travels farther than its stain suggests.

Alvin repairs that follow water and mold
Bathroom and closet checks for an older Alvin house
Press on the shower tile
Press tiles near the shower floor every few months. Hollow or shifting tiles mean water has reached the bed behind them.
Watch the baseboard next door
Dark or swelling baseboard on the far side of a shower wall is often the first visible sign of a leak inside it.
Follow the bath fan duct
From the attic, confirm the bath fan duct runs to an outside vent rather than ending in the insulation. A fan venting into the attic just moves the moisture.
Check closet floors under appliances
Look for soft spots or stains around a water heater or washer. Decking there absorbs slow drips long before the leak shows anywhere else.

Yes. Alvin is in Brazoria County rather than Galveston County, and it is part of the area we work from our League City office. Tell us what you are seeing, and we will point out what to look at before the visit.
Sometimes. If readings show the water stayed close to the shower, we open only that section, dry the cavity and rebuild it. A failed pan liner usually means the shower floor itself has to come up.
A musty smell, peeling paint or dark spots on baseboard are the usual clues. We confirm with moisture readings before opening the wall, then contain the area if mold is found.
Coverage usually follows the water. Mold from a sudden leak is often covered along with it, while mold from long-term seepage is often excluded. Your adjuster decides, and we supply the readings and photos.
Yes. We handle leaks, drying and mold in mobile homes as well as site-built houses, including subfloor decking and insulation work under the floor.
