Retaining walls on Fairfield lots
In Fairfield's older neighborhoods (50% 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 Fairfield homes are single-family (78%), 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 Fairfield was built in 1960, close to the 1960s house that's typical statewide. That's newer than next-door Bridgeport (median 1954) and older than Westport (1968).

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

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