Foundation work in Norwalk
Half of Norwalk's homes were built before 1967, and the poured and block foundations from that era mostly hold up well. The calls are usually a leaking crack, an addition or a garage.
Parts of Norwalk near Long Island Sound are in FEMA flood zones, where additions and rebuilds can require elevated foundations with flood vents. The city's floodplain manager decides, and we build to the approved plans.
The median home in Norwalk was built in 1967, close to the 1960s house that's typical statewide. That's newer than next-door Darien (median 1957) and older than Stamford (1972).

Concrete foundations in Norwalk: questions
Do I need a permit for a foundation in Norwalk?
Yes. New foundations, additions and garages need a building permit from Norwalk's building department, and most towns inspect footings before the pour. Deck and porch footings are usually part of the deck permit.
How deep are footings in Norwalk?
42 inches below grade, the same as everywhere in Connecticut. The state building code sets the frost depth statewide, and towns can't change it.
Do flood zone rules affect a foundation near the shore?
They can. In a FEMA flood zone, additions and substantial rebuilds may need elevated foundations with flood vents. Norwalk's floodplain manager makes the call; we build to the approved plans.
Do you pour foundations near Norwalk?
Yes. We also pour foundations in Darien, Westport and New Canaan, and across Fairfield County.
