Retaining walls on Wilton lots
Half of Wilton's homes were built before 1971, and the landscape walls that went in with them, often timber or unreinforced block, are reaching the end of their life. Most Wilton homes are single-family (84%), and wall work here is usually about usable yard: terraces, garden walls and level spots for a patio or play area.
Ledge and boulders show up in a lot of Wilton wall excavations. Sometimes the rock becomes part of the design; sometimes it has to go. We sort that out at the estimate.
The median home in Wilton was built in 1971, newer than the 1960s house that's typical statewide. That's newer than nearby Fairfield, where the median is 1960.

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

Retaining walls in Wilton: questions
Do I need a permit for a retaining wall in Wilton?
Walls over 4 feet from the bottom of the footing, or walls holding up a driveway, slope or building, need a permit from Wilton'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 Wilton?
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.
What if there's ledge where the wall goes?
Ledge can be the best base there is. We clean it, step the footing or base to the rock, and make sure water can drain off it.
