Deck Builder in Middletown, CT
Decks, porches, patios and siding from our Connecticut office on Centerpoint Drive in Middletown. We work across the city and the towns around it, from Cromwell and Portland to Durham and Haddam.
In Middletown, the age of your house shapes a new deck as much as the yard does. On an older home near downtown or Wesleyan, we check the framing before anything gets attached, and a newer house further from the river is usually simpler. We build decks, porches, patios and siding for both, out of our office on Centerpoint Drive. Sustainable Decks has 1000+ projects completed and a 5.0 rating on Google, and one crew stays on your job from the first footing to the final walkthrough.

How is building a deck in Connecticut different?
Mostly in what goes into the ground. Connecticut's building code sets frost depth at 42 inches, where Massachusetts sets 48, so footings in Middletown go to 42 inches unless the Middletown Building Department asks for more on your lot. The same code lets a freestanding deck, one that isn't attached to the house, skip frost-depth footings altogether, which can make a detached deck or platform simpler to build. Framing is sized for the 30 pounds per square foot of ground snow the code sets for Middletown. Permit thresholds are Connecticut's own too, so we check what your address needs before we price the job.
New decks on older Middletown houses
They need a careful look before anything gets attached. Many of the older homes near downtown and the Wesleyan campus were framed before modern platform framing, so we check what's behind the siding before a ledger board is bolted to the house. If the framing can't carry a deck, the deck stands on its own posts instead. The newer subdivisions further from the river are standard current-code houses and more straightforward. Lots close to the Connecticut River can hold water, so on those the drainage gets settled before the shape of the deck does.

What our customers say
Questions people ask about building in Middletown
Do you have an office in Connecticut?
Yes. Sustainable Decks Connecticut is at 101 Centerpoint Drive in Middletown, and our jobs across the Middletown area run from there.
Do decks in Connecticut need the same footings as in Massachusetts?
No. Connecticut's code sets frost depth at 42 inches, where Massachusetts sets 48, and in Connecticut a freestanding deck that isn't attached to the house doesn't need frost-depth footings at all. The Middletown Building Department can still ask for more on a particular lot.
Do I need a permit for a deck in Middletown?
Connecticut sets its own permit thresholds, separate from the Massachusetts ones, so we confirm what your address needs with the Middletown Building Department before we quote. When a permit is required, we file it.
How long does a deck take to build?
A standard single-level deck usually runs one to two weeks once material arrives, weather and permit timing aside. Porches, patios and multi-level decks run longer. You get a real schedule in the proposal, not a range.
Do you offer financing?
Yes. Financing is available on larger projects, so the scope of the job isn't limited to whatever fits in savings this month.
