Meet David.

Hi, I’m David Merchant, owner and operator of 603 Decks LLC.

As a veteran-owned and operated carpentry company, I take pride in providing homeowners throughout New Hampshire’s Seacoast region with quality craftsmanship, honest communication, and dependable service.

After serving in the United States Marine Corps and graduating from the University of New Hampshire, I founded 603 Decks with a simple goal: provide homeowners with a contractor they can trust. From the initial estimate to the final walkthrough, I believe in clear communication, attention to detail, and building projects that stand the test of time.

Whether I’m constructing a composite deck, building custom cabinetry, installing doors and windows, repairing structural framing, or completing interior renovations, I approach every project with the same mindset: do the job right the first time.

As an owner-operated company, when you contact 603 Decks, you’re working directly with me. I personally manage and complete the work, ensuring every project receives the care and craftsmanship it deserves.

Thank you for considering 603 Decks for your next home improvement project. I look forward to helping bring your vision to life.
