There’s a house down in St. George I still think about. Old place near the water, and the owner had spent good money three times over sealing the inside of his basement wall, paint-on coatings, a fresh skim of parge, the works, and every spring the water came right back through like he’d done nothing. When he finally called me I asked one question: had anybody ever looked at the outside of that wall? Nobody had. My name’s Sal, and I’ve spent fifty-odd years doing masonry and foundation work up and down Staten Island, St. George, West Brighton, Tompkinsville, the whole North Shore where a lot of the housing stock…

My name is Mark, and I’ve spent almost twenty years buying, fixing, and holding onto houses around Atlanta, Georgia — plenty of them century-old bungalows and postwar ranches sitting on nothing but a crawlspace and a prayer. I keep a cheap laser level and a $4 pack of crack monitors in my garage, and once a season I walk the whole property looking for the same handful of things. I’m not a structural engineer and I don’t pretend to be one, but I’ve learned that catching foundation movement early is a DIY job even when the fix isn’t. On this Georgia red clay, movement isn’t a question of if but…

The Cedar Park backyard I walked last August looked fine for a drought — cracked clay, dead St. Augustine, nothing dramatic. Then the homeowner pulled up phone video from the previous May: a sheet of water sliding off the roof, hitting the ground three feet from the foundation, and pooling against the slab like a moat. That’s the whole problem with grading and downspouts on Central Texas clay. It hides for months, then does its damage in a single storm. I’ve spent years designing and repairing yards around Cedar Park and the wider Austin metro, and water management is the first thing I check on a property, not the last.…

I lost a deal in St. George last year over a puddle. The home inspector’s flashlight caught a damp tide line on the basement wall, the buyers pictured a flooded foundation, and a clean offer turned into a $12,000 credit request. When I walked the exterior afterward, the cause was almost comically simple: the grade sloped toward the house and both front downspouts dumped water three feet from the foundation. I’ve been listing homes on Staten Island’s North Shore long enough to know that standing water at the foundation is one of the fastest ways to scare a buyer and shave your price, so now I walk the perimeter of…

My name’s Joe Marchetti, and I’ve spent the last twenty-two years repointing and rebuilding brick foundations around New Haven, Connecticut. One job that’s stuck with me was a 1908 worker’s cottage in Fair Haven, where the owner met me in the basement with a flashlight pointed at the sill. “Watch this,” she said, and pressed her thumb into a joint between two bricks. The mortar came away like wet cornbread. That crumbling seam is where the story of almost every old New Haven foundation I’ve worked on begins. Fair Haven’s housing stock leans old and brick-heavy — a lot of it went up between the 1880s and 1930s — and…

I’m Tom Reilly, and I’ve done masonry and foundation repair around New England for close to eighteen years. My sister and her husband bought a house in Buda, just south of Austin, and the first time I visited I noticed a door that wouldn’t latch and a hairline crack stair-stepping up the brick by the garage. Back home our foundation enemy is frost, so I figured water and freezing were behind it. Wrong problem, wrong state. Down there the ground itself moves, and it moves because of the clay under nearly every yard from Buda north through Kyle and the rest of the fast-growing suburbs south of Austin. I spent…
