7 Signs Your Pavers Need Repair (Before a Small Fix Turns Big)

The most common paver repair call in the Orlando area is a sunken area. You will usually spot it after a summer storm: a shallow puddle that sits on the driveway or patio long after the rest of the surface has dried. Look closely and you may see the pavers in that area sitting a quarter inch or more below their neighbors.

Sinking almost always starts below the surface. Central Florida soil is mostly sand, and if the base under your pavers was not compacted in thin layers, or if a downspout, irrigation head or pool overflow keeps dumping water in one spot, the base slowly washes out and settles. Tire paths on driveways and the area next to the pool are classic trouble zones.

The fix is to lift the pavers in the low area, add and compact new base material, re-screed the bedding sand and reset the stones. If a downspout or sprinkler is the cause, that needs to be redirected at the same time or the spot will sink again.

If a paver moves when you step on it, or you hear a hollow click as you walk across the patio, the interlock in that area has broken down. Pavers stay tight because joint sand locks them together and an edge restraint holds the whole field in place. Lose either one and the stones start to wander.

Loose pavers are more than an annoyance. They are a trip hazard, especially on pool decks where people walk barefoot, and once a few stones move, the ones around them follow. On driveways, shifting often shows up where cars turn their wheels while parked.

Repair usually means pulling the loose stones, checking the bedding layer, resetting them tight and refilling the joints with fresh sand, often polymeric sand that hardens after it is wet down.

Look at the lines between your pavers. On a healthy installation the joints are filled nearly to the top. If you can see deep, empty gaps, the sand has been washed out by heavy rain, blown out by pressure washing, or carried off by ants. Central Florida gets intense afternoon downpours from late spring into fall, and that water moves a lot of loose sand.

Empty joints let pavers move against each other, which leads to chipped edges and the loose stones described above. Re-sanding is one of the least expensive maintenance steps you can take, and it is often done as part of a cleaning and sealing service.

Weeds growing between pavers are a symptom, not just a cosmetic problem. They only take root when there is open space and organic debris in the joints. Ant hills popping up along the lines tell you the joint sand is loose enough for insects to tunnel through, and over time they can hollow out the bedding layer underneath.

Pulling weeds by hand helps for a week. A longer lasting fix is a deep clean to remove the debris, fresh joint sand, and a sealer that helps lock the sand in place so seeds and ants have a harder time getting started.

Walk the outside edge of your driveway, walkway or patio. If the border row is tilting outward, separating from the field, or crumbling into the lawn, the edge restraint may have failed or was never installed properly. Without that restraint the whole surface slowly spreads, and gaps open up in the middle.

This is common where a driveway meets the lawn and car tires ride over the edge, and around pool decks where the border meets soil that stays wet from irrigation. A repair crew can reset the border row and install or replace the restraint so the rest of the field stays tight.

A single cracked paver is not a crisis. Unlike a concrete slab, one damaged stone can be popped out and replaced on its own. Cracks often show up after a heavy truck or trailer parked on a driveway that was built for cars, or where a stone was already sitting unevenly before the load hit it.

Deep oil stains, rust marks from irrigation water and patches of black algae can sometimes be cleaned out. When they cannot, swapping the affected pavers is an option. Keeping a few spare stones from the original install makes color matching much easier, so it is worth asking whether any extras were left behind.

Raised ridges or humps, often in a line, usually point to roots growing under the base. Oaks and other large trees near driveways in older Orlando and Kissimmee neighborhoods are frequent culprits. Repair involves lifting the pavers, dealing with the roots in a way that is safe for the tree when possible, rebuilding the base and resetting the stones.

Some signs suggest the problem is bigger than a patch. If low spots appear across most of the surface, if the pavers were laid on a thin layer of sand with almost no base, or if the area floods every time it rains, a partial rebuild or better drainage may be the right call. An on-site look is the only honest way to tell the difference.

Most homeowners are surprised to learn that small repairs are typically priced in the low hundreds to the low thousands of dollars depending on the area involved, while larger rebuilds cost more.
