Retaining walls on Norwalk lots
Half of Norwalk's homes were built before 1967, and the landscape walls that went in with them, often timber or unreinforced block, are reaching the end of their life. Norwalk mixes single-family homes (45%) with multi-family lots, so walls here range from garden terraces to walls holding up shared driveways.
Near Long Island Sound, walls deal with sandy soils, and waterfront structures need state coastal approvals, so our shoreline work stays on the landward side: garden, terrace and driveway walls.
The median home in Norwalk was built in 1967, close to the 1960s house that's typical statewide. That's newer than next-door Darien (median 1957) and older than Stamford (1972).

Wall rules in Norwalk. Under the Connecticut State Building Code, a retaining wall over 4 feet tall, measured from the bottom of the footing, or one carrying a driveway, slope or building above it, needs a permit and generally an engineered design. Work near wetlands or watercourses can also need a sign-off from Norwalk's inland wetlands commission. We check both before we price.

Retaining walls in Norwalk: questions
Do I need a permit for a retaining wall in Norwalk?
Walls over 4 feet from the bottom of the footing, or walls holding up a driveway, slope or building, need a permit from Norwalk's building department and generally an engineer's design. Shorter garden walls usually don't, though zoning setbacks and wetlands rules can still apply.
How much does a retaining wall cost in Norwalk?
Block walls fall in our planning range of $40–$80 / face sq ft of wall face, poured concrete walls $60–$120 / face sq ft. Height, drainage, access and any engineering set the final number.
Do you build seawalls?
No. Waterfront structures need state coastal permits and marine contractors. We build the garden, terrace and driveway walls on the landward side.

Yes. We also build retaining walls in Darien, Westport and New Canaan, and across Fairfield County.
