Repairing concrete in Derby
Half of Derby's homes were built before 1965. Residential concrete from that era was often poured without air entrainment, which is why so many older walks and steps here are scaling. Derby's mix of single-family homes (40%) and multi-family buildings means repair work for homeowners and property managers alike.
On Derby's slopes, water running under slabs washes out the base, so cracked and dropped panels are common. Fixing the water path is part of the repair. Much of Derby's concrete meets the public way, from front steps to walks and aprons, so trip hazards there are a liability as well as an eyesore.
The median home in Derby was built in 1965, close to the 1960s house that's typical statewide. That's newer than next-door Ansonia (median 1954) and older than Shelton (1977).

Permits for repairs in Derby. Most surface repairs, like crack sealing, patching and resurfacing, don't need a permit. Work in the city's right-of-way, such as a public sidewalk or apron, usually does, and structural foundation repairs need a building permit and often an engineer.

Concrete repair in Derby: questions
Is it worth repairing old concrete in Derby, or should I replace it?
If the slab hasn't moved and the damage is at the surface, repair or resurfacing usually makes sense. If it has settled, heaved or cracked through, replacement or lifting is the better spend. We'll show you which at the estimate.
Do you repair concrete steps in Derby?
Yes. We rebuild broken nosings and corners and resurface scaled treads when the steps are solid. If they've pulled away from the house, we'll quote replacement instead.
Our walk keeps cracking where it slopes. Why?
Water running under the slab carries the base downhill. We repair the concrete and redirect the water.
