Retaining walls on Guilford lots
Half of Guilford's homes were built before 1973, and the landscape walls that went in with them, often timber or unreinforced block, are reaching the end of their life. Most Guilford homes are single-family (85%), 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 Guilford was built in 1973, newer than the 1960s house that's typical statewide. That's newer than nearby North Haven, where the median is 1964.

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

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