Retaining walls on Darien lots
In Darien's older neighborhoods (57% of homes predate 1960), failed walls are a common job: rotted timber, block with no drainage, and old dry-laid stone that was never meant to hold back a driveway. Most Darien homes are single-family (86%), and wall work here is usually about usable yard: terraces, garden walls and level spots for a patio or play area.
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 Darien was built in 1957, older than the 1960s house that's typical statewide. That's older than nearby Stamford, where the median is 1972.

Wall rules in Darien. 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 Darien's inland wetlands commission. We check both before we price.

Retaining walls in Darien: questions
Do I need a permit for a retaining wall in Darien?
Walls over 4 feet from the bottom of the footing, or walls holding up a driveway, slope or building, need a permit from Darien'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 Darien?
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 Stamford, Norwalk and New Canaan, and across Fairfield County.
