Start with the cause
A sunken corner or a weedy joint is a symptom. The fix lasts only if it addresses the cause, so every restoration starts with a look at what's happening underneath and around the pavers.
- Settling or sinking usually traces to the base: water washing out bedding sand, soft or poorly compacted soil, an old utility trench, or a failed edge restraint.
- Heaving is often caused by roots.
- Empty joints come from washout, pressure washing, or joint sand that was never fully filled.
- Stains have many sources — irrigation water, leaves, oil, rust from furniture, or fertilizer.
Common conditions
Material studyEfflorescence is a white haze of natural salts carried to the surface of concrete pavers by moisture. It's common, especially on new pavers, and isn't a structural problem. It often fades with time and weather; cleaners made for efflorescence can remove it when needed.
Material studyOrganic growth — algae, moss, or mildew — shows up in shady, damp areas and along joints, and can make surfaces slick. Cleaning, better drainage, and trimming back overhanging plants help.
Material studyJoint sand loss leaves pavers free to rock and invites weeds and ants. Refilling joints — with regular or polymeric sand, installed as the manufacturer directs — restores the interlock.
Material studyRust staining in curved patches is common in Central Florida where irrigation water carries dissolved iron, often from wells. Stain-specific cleaners can help, and adjusting sprinkler heads or treating the water keeps it from returning.
Lift, correct, and reset
When an area has settled, the pavers are carefully removed and stacked, the base is corrected and re-compacted, and the same pavers are reinstalled, then re-sanded and compacted. Reusing the original pavers keeps color and wear consistent. Broken units can be replaced, but exact matches aren't always possible when a product has been discontinued or older pavers have weathered — we'll tell you before the work starts if that's likely.
If settling keeps coming back, the cause is often water: a downspout discharging at the edge, a low spot, or a slope running the wrong way. Those problems may need their own scope. See the drainage guide.
Cleaning and sealing
Cleaning should match the surface and the stain: the right detergent or specialty cleaner, and pressure that removes dirt without scarring the pavers or blowing out every joint. Joints are usually refilled after cleaning.
Material studySealing is optional. A sealer can deepen color, make cleaning easier, and help stabilize joint sand. It also adds upkeep, and results depend on the product:
- Finish. Natural or matte sealers change the look very little; wet-look sealers darken and add sheen.
- Traction. Some sealers make surfaces slicker when wet — an important question around pools.
- Timing. New concrete pavers are usually given time to cure, and efflorescence to fade, before sealing.
- Upkeep. Many sealers need reapplication every few years, and failing film-forming sealers may need to be stripped before resealing.
What restoration can't do
Restoration improves most surfaces, but it has limits. It can't make a base that was built too thin behave like a new one everywhere, it can't guarantee color matches for discontinued products, and sealing won't fix settling or drainage problems. When a surface has widespread base failure, rebuilding may be the better value — and we'll say so.
What affects the cost
- The area involved and how much needs lifting and resetting
- Base repair and any drainage corrections
- Replacement pavers
- Type of stains and cleaning needed
- Stripping an old sealer, and the sealer chosen
- Access, furniture moving, and working around pools or landscaping
