Even quality pavers face challenges in South Florida’s heat, rain and humidity. Here are the five most common paver problems we see — and exactly how to fix each one.
1. Persistent Weed and Moss Growth
South Florida’s warmth and humidity let weeds, moss and algae take hold in the joints between pavers. Most weeds start from seeds that land in the joints from above, not from below, so they appear wherever joint sand has washed out and dirt has collected. Besides looking untidy, growth holds moisture against the surface and makes shaded areas slippery.
How to fix it: pull or treat the growth, clean the surface, then refill the joints with fresh sand so there is no room for dirt to settle. Sealing afterward helps hold the sand in place. Our paver cleaning and sealing service covers all three steps, and our guide on how to clean pavers and what it costs explains what you can do yourself.
2. Sinking and Uneven Pavers
Dips, ruts along the wheel paths and pavers that rock underfoot point to a problem beneath the surface. The usual causes are a base that was laid too thin or not compacted, sandy soil shifting under it, or water washing material out from below.
How to fix it: the affected pavers are lifted, the base is rebuilt and compacted, and the same pavers are relaid level. Adding sand on top does not last. For the full process, read why your driveway is sinking and how to fix sinking pavers.
3. Standing Water and Poor Drainage
Puddles that remain long after the rain stops mean the surface is not sloped correctly, a section has settled, or a drain is blocked. Standing water speeds up algae growth, stains the pavers and slowly softens the base underneath, which leads to more settling.
How to fix it: clear the drains first. If water still collects, the low section is lifted and relaid with the correct slope, and a channel drain can be added where water has nowhere to go. Our guide to pool deck standing water and drainage goes through the options.
4. Fading, Stains and White Haze
Strong sun fades unsealed pavers over time. Driveways pick up oil and tire marks, pool decks pick up rust and leaf stains, and many surfaces develop a white, chalky film called efflorescence, which is mineral salt carried to the surface by moisture.
How to fix it: each stain needs its own cleaner, so identify it before scrubbing. Efflorescence often fades by itself and can be removed with a cleaner made for it. Once the surface is clean and dry, sealing slows fading and makes future stains easier to lift. See why paver sealing matters in the Florida sun.
5. Loose Edges and Shifting Pavers
Pavers stay tight because the outer edge is held in place. When the edge restraint fails or was never installed, border pavers lean outward, joints widen and the pattern drifts apart. Tree roots near the edge cause the same thing by lifting sections from below.
How to fix it: the loose border is lifted, the edge restraint is replaced or added, and the pavers are reset tight and re-sanded. Where roots are the cause, the pavers can be lifted and relaid once the root is dealt with.
Repair or replace? Most of these problems can be repaired because pavers can be lifted and reused. Replacement makes sense when the whole surface is uneven, the pavers themselves are worn or broken in many places, or you want a different layout. Our comparison of paver restoration vs replacement helps you decide, and our paver repair and remodel service covers both.
