Greenwich housing runs to center-hall colonials, shingle-style houses, and backcountry estates, a large share of them built before 1950. Many decks here were attached to houses that were never detailed to carry one.

Yards in Greenwich range from large back yards off center-hall colonials, plus tight shoreline lots. The most common request is multi-level decks off the back of older colonials.

Every deck in Greenwich has to handle salt air near the harbor, which corrodes standard fasteners and hangers. That decides the hardware, the lumber rating, and how the boards are spaced.

Why Greenwich Decks Fail and How We Build Them

Most deck failures in Greenwich start at the ledger. A ledger that was never flashed lets water into the rim joist, and the rot spreads where nobody looks.

Footings go below frost depth, because coastal wind, salt, and repeated freeze and thaw cycles will heave any post set too shallow.

Hardware matters as much as lumber. Joist hangers, lag bolts, and fasteners are rated to match the treated wood, because standard steel corrodes in contact with it.

Railings and stairs are built to code height and spacing. On a Greenwich deck used by kids and guests, that is the part the inspector checks hardest.

Deck Questions from Greenwich Homeowners

Yes. We work in Greenwich and the surrounding towns, including Old Greenwich, Cos Cob, Riverside, and Byram. If you're right on the town line, call and we'll confirm before scheduling a visit.

It depends on size, height, lumber, railings, and site conditions. We don't quote decks by phone, because the number would be wrong. The site visit and the written estimate are free.

In most cases, yes, especially when the deck is attached or raised. In Greenwich that goes through the Town of Greenwich building department. We handle the permit and schedule the inspections.

It comes down to the framing. If the joists, beams, and ledger are solid, repairs make sense. If rot has reached the structure, replacement is safer and usually costs less over time.

A well-built one that gets sealed on schedule lasts a long time. The framing usually outlives the boards. Skipped maintenance and standing snow are what shorten it.

Spring through fall, once footings can be dug. Late winter is the best time to plan, since permits take a while. Call (203) 942-9495 and we'll give you an honest lead time.
