Sunken concrete in Greenwich
Half of Greenwich's homes were built before 1963. Slabs that old have had decades of downspout washout under them, and a lot of what looks like a failed slab is a sound slab sitting on a void. Greenwich's mix of single-family homes (63%) and multi-family buildings means leveling for homeowners and for landlords clearing trip hazards.
Near Long Island Sound, sandy or filled soils wash out easily under slabs. Foam fills those voids without adding much weight.
The median home in Greenwich was built in 1963, close to the 1960s house that's typical statewide. That's newer than next-door Darien (median 1957) and older than Stamford (1972).

Concrete leveling in Greenwich: questions
How much does concrete leveling cost in Greenwich?
Lifting one to three walkway panels falls in our planning range of $600–$1,500; a driveway or garage apron runs $1,200–$3,000. The size of the void and the material set the price.
Can you level a sunken sidewalk in Greenwich?
If the panel is in one piece, usually yes. For a public sidewalk we confirm the town accepts lifting before we do it; some towns want replacement.
Will a lifted slab stay up near the shore?
If the cause is handled, yes. Sandy soils wash out, so we seal joints and redirect water along with the lift.
Do you level concrete near Greenwich?
Yes. We also level concrete in Stamford, Darien and New Canaan, and across Fairfield County.
