STATEN ISLAND, N.Y.—The Staten Island Board of Realtors (SIBOR) reminds you that knowing the early warning signs of foundation troubles can head off problems that ultimately could cost tens of thousands of dollars to fix.
As concrete cures, it shrinks slightly. Where the concrete can’t shrink evenly, it tends to crack. Concrete and block foundations usually have at least a few cracks. The trick is recognizing which are insignificant and which are serious.
Here’s a list, provided by House Logic, from least to most serious:
Hairline cracks in the mortar between concrete blocks are rarely worth worrying about.
Cracks at an L-shape section, such as where a foundation steps down to follow a hillside, are probably shrinkage cracks, especially if they meander and taper down to a hairline. These aren’t a structural issue, though you might need to plug them to keep the basement or crawl space dry.
Stair-step cracks in masonry joints are a bigger concern, especially if the wall is bulging or the crack is wider than ¼ inch. A plugged gutter or other moisture problem outside is probably exerting pressure on that part of the wall.
Horizontal cracks are most serious. It may be that water-saturated soil froze and expanded, pushing in and breaking the foundation. Or, you may have soil that expands when damp and shrinks when dry. The bad news: You probably need a whole new foundation.
