Foundations in Port St. Lucie
For a Port St. Lucie house on a concrete slab, foundation worries usually start the same way: a crack in the garage floor, a door that sticks, tile that pops or a gap opening between a wall and the ceiling. Some of those are normal shrinkage. Some are signs of settlement that's still moving. The work is in telling them apart before you pay for a repair.
Cracks: what to watch
Hairline cracks in a slab or in stucco are common and often stop on their own as concrete cures and shrinks. Signs that deserve a closer look:
- cracks wider than a credit card is thick, or one side higher than the other;
- cracks that keep growing, which you can check by marking each end with a pencil and the date;
- doors and windows that start to stick or won't latch;
- diagonal cracks running from the corners of doors and windows;
- floors that slope, or tile that cracks in a line;
- gaps where the slab meets the walls or baseboards.
Rain and drainage
NOAA's engineering weather data for Vero Beach, the nearest station to Port St. Lucie, lists a 100-year rainfall rate of 4.5 inches per hour and a 50-year basic wind speed of 140 mph. Heavy rain matters to a foundation because water that collects along the slab can soften and wash away the soil beneath its edges. Look at where your gutters and downspouts empty, whether the ground slopes away from the house and whether water stands along any wall after a storm. Fixing drainage is often the first and cheapest part of a foundation repair.
Get an independent evaluation
A company that sells foundation repair has a reason to find a foundation problem. Before you agree to piers or slab lifting, consider paying for an evaluation from a structural engineer who doesn't sell the repair. Ask the engineer:
- whether the movement is still active or happened long ago;
- what's causing it: soil, water, a plumbing leak under the slab or something else;
- what repair, if any, they'd recommend, and what they'd want monitored first.
A leak in a pipe under the slab can wash out soil and cause settlement. A plumber can test the lines before any foundation work starts.
Repair methods
Common repairs include sealing and monitoring cracks, correcting drainage, injecting foam or grout to lift and support a sunken slab, and driving or pushing piers beneath the foundation to transfer its weight to firmer soil. Ask any contractor why they recommend a particular method for your house, how many piers or injection points they propose and where, what they expect to happen to existing cracks, and what the warranty covers, including whether it transfers to a buyer.
Florida's licenses
Florida contractors either hold a state certificate of competency, shown by a license number beginning with C, which lets them contract anywhere in the state, or a registration, beginning with R, which lets them contract only in the local jurisdictions where they met competency requirements. Look the contractor up on DBPR's license search and check that the license type matches structural work. Ask whether the job needs a permit and an engineer's letter.
When there's an insurance claim
Foundation coverage depends on the cause and the policy. If you file a claim and disagree with the result, Florida's Division of Consumer Services, in the Department of Financial Services, advocates for policyholders free of charge through its Insurance Consumer Helpline, 1-877-693-5236, and offers a free mediation program for residential property insurance claim disputes. Keep the engineer's report, photos and repair estimates together for that conversation.
