Foundation work in Wilton
Half of Wilton's homes were built before 1971, 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.
Ledge is common under Wilton lots. Footings can bear directly on sound rock, and when a basement needs the rock gone, removal is priced as its own line.
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.

Concrete foundations in Wilton: questions
Do I need a permit for a foundation in Wilton?
Yes. New foundations, additions and garages need a building permit from Wilton'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 Wilton?
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.
What if we hit ledge digging the foundation?
Footings can bear on sound rock. If rock has to come out for a basement, we price removal openly before we continue.
Do you pour foundations near Wilton?
Yes. We also pour foundations in Weston, New Canaan and Ridgefield, and across Fairfield County.
