Retaining walls on Avon lots
In Avon's newer neighborhoods (half the housing was built after 1981), walls are often what makes a sloped lot usable: a level backyard, a pool terrace or a wider driveway. Avon mixes single-family homes (70%) with multi-family lots, so walls here range from garden terraces to walls holding up shared driveways.
Near Talcott Mountain, walls often sit on or against ledge. Rock makes a good foundation, but water running along its surface needs a way out from behind the wall. Lots that fall toward the Farmington River need walls that drain well, and work near rivers and wetlands usually needs a sign-off from Avon's inland wetlands commission first.
The median home in Avon was built in 1981, newer than the 1960s house that's typical statewide. That's newer than nearby West Hartford, where the median is 1955.

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

Retaining walls in Avon: questions
Do I need a permit for a retaining wall in Avon?
Walls over 4 feet from the bottom of the footing, or walls holding up a driveway, slope or building, need a permit from Avon'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 Avon?
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?
Near Talcott Mountain there often is. Footings or base courses are stepped onto the cleaned rock, and drainage is routed off its surface.

Yes. We also build retaining walls in Farmington, West Hartford and Canton, and across Hartford County.
