New Deck Installation for Homes in Milford & Fairfield County

What's Involved

Every new deck starts with footings dug below Connecticut's frost line, typically 36-42 inches depending on your town's building code, then ledger attachment to the house (or a freestanding frame if ledger attachment isn't structurally sound), joist framing, decking, and railing. Timeline runs one to two weeks for a standard-size deck, longer for multi-level designs or built-in features like benches and planters.

Wood vs. Composite

Wood remains the lower-cost entry point, and for homeowners who don't mind annual maintenance, it's still a solid choice. The real decision within "wood" is species: pressure-treated pine covers most budgets but needs annual staining or sealing to hold up against CT's wet-dry cycling; cedar offers better rot resistance and can often go two to three years between treatments; tropical hardwoods like ipe outlast both, resisting rot and insects for 25+ years, at a materials cost that starts to rival composite. Pressure-treated framing sits underneath regardless of which decking material goes on top — even composite decks are built on pressure-treated joists.

How This Differs

This page covers new deck construction in either material. If your project is a ground-level platform rather than an elevated deck, see Patio Decks, which has different footing and railing code requirements. If you're replacing a deck that already exists, that's Deck Replacement, not new installation. If you already have a deck and just want a design refresh, see Deck Remodeling.

Local Conditions

Every town on this list requires a permit for a new deck attached to the house, and inspectors check footing depth against local frost line requirements before the frame goes up — skipping that step is the most common reason we get called to fix someone else's work later. Connecticut's freeze-thaw cycle and humid summers are also tough on wood decking specifically, which is a big part of why homeowners planning to stay long-term often choose composite or ipe over pressure-treated pine from the start.

We've built decks for over 30 years combined, and every new installation carries a 10-year labor warranty.
