Deck Builder in Middlesex County, CT
Our Connecticut office is in Middletown, inside Middlesex County, the Connecticut River runs through the middle of our coverage area here, not just along an edge.
About Middlesex County
Middlesex County, Connecticut is built around the Connecticut River, Middletown, Cromwell, Portland, Haddam, Durham, and East Hampton, several of them genuinely split by the river rather than just bordering it.
Sustainable Decks covers ground from Middletown to Haddam, with the same licensed Massachusetts Construction Supervisor and the same 5-star Google record following every project across Middlesex County.
River-adjacent lots in Middletown, Cromwell, Portland, and Haddam deal with drainage and flood-plain considerations that the higher-ground sections of the same towns don't. We check which applies before quoting, not after.
Served from our Middletown, CT office, 101 Centerpoint Drive.

Permit and build phase
One crew, one permit filed under our name, from the first footing to the final screw.
