Pavers in Frederick & Central MD
Pavers almost never fail. Bases do, and the surface reports it. Which means the repair starts with finding out what the base did rather than with lifting stone.
Quick answer
Lifting and resetting a settled area on corrected base runs $18 – $35 per square foot, with a minimum visit of $650 – $1,200 because mobilising, lifting and compacting has a floor regardless of how small the dip is. Reinstating edge restraint is $14 – $28 per linear foot and re-sanding an existing field $1.50 – $3.50 per square foot. We quote after looking, because the price follows what the base did rather than the area.
The work
The great advantage of a segmental surface is that it comes apart. A settled patch in a paver patio is a repair; the same settlement in a concrete slab is a crack you live with or a slab you replace. Units can be lifted, the base underneath corrected, and the same stone reset — and because those units have weathered alongside their neighbours for years, the repair genuinely disappears in a way a colour-matched patch never does.
What makes a repair last, though, is finding out why. A dip in a patio is a symptom, and resetting the pavers over the same void buys you one or two seasons before it comes back. So the first thing we do is work out what the base did: whether it was built too shallow, whether it was compacted in one pass instead of lifts, whether the stone has worked down into clay subsoil, whether the perimeter has spread because there is no edge restraint, or whether a downspout has been washing the fines out of one corner for six years.
Sometimes the answer is that a repair is not the economical route. A patio with three separate dips, open joints across the whole field and an edge that has crept outward is telling you the base was never adequate, and fixing it in patches means being back three more times. We will say so. Removal is $4 – $9 per square foot and we would rather quote an honest rebuild than sell a sequence of repairs.

Paver repair and relevelling
What’s included
Written into the estimate, not assumed. If something on your job is not on this list, it gets priced and named before anyone starts.
We look at the pattern of the movement, where the water goes, what the perimeter is doing and what comes up when we lift the first few units. A dip in one spot under a downspout is a different problem from a general sag across a whole field, and they get different repairs.
Pavers come up carefully and go back in the same orientation. Weathered units matched to weathered units is the whole reason this repair is invisible — new stone from the same range will not match pavers that have been outside for eight years, however identical the name on the pallet.
The void gets excavated to sound material, refilled with the right stone and compacted in lifts, with separation from the subsoil where clay is working up. Throwing sand into a dip and resetting on top of it is the repair that fails again, and we will not do it that way.
Where the field has spread, the perimeter is the cause and not the casualty. Restraint goes back in properly, anchored, before the outer rows are reset — otherwise the field keeps creeping and the joints keep opening however well the middle is relaid.
If a downspout, a bad grade or a missing extension is what washed the base out, fixing the patio without fixing that is just rescheduling the problem. We extend the discharge past the hardscape or correct the fall, and say so in the quote rather than treating it as out of scope.
Joints swept full with polymeric sand and set, so the repaired area is locked into the field around it rather than sitting in it as a loose panel. A reset patch with empty joints spreads at its own edges within a season.

Almost always, and it is the main reason this repair works. Units come up, get kept in order and go back in the same orientation. Weathered stone matched to weathered stone is invisible; new units from the same product line are not, because eight years of sun and rain have moved the colour. We usually only need a handful of replacements for units that have cracked, and we would rather source those from a hidden area of your own field.
Four causes, usually in combination: the base was too shallow, it was placed in one lift instead of several so the bottom never compacted, there was no separation from clay subsoil so the two have mixed, or there is no edge restraint and the field has spread. Water is the accelerant on all four — a downspout discharging at the edge of a patio washes the fines out of a base in a few seasons. The blog post on this site goes through all four properly.
One or two localised dips with a findable cause are a repair, and a good one. Multiple separate dips, open joints across the whole field, an edge that has crept and a surface that no longer drains the way it was built to are a base that was never adequate, and patching that means coming back repeatedly. At that point removal at $4 – $9 per square foot plus a proper rebuild is cheaper over five years. We will tell you which one you have, including when the answer costs us the smaller job.
Same crew, same visit
Most pavers jobs are two or three of these at once, which is why they are priced and scheduled together rather than as separate call-outs.
