Deck Builder in Marshfield, MA

TRUST KB CARPENTRY FOR BEAUTIFUL, BUILT-TO-LAST DECKS ON The South Shore

Marshfield homeowners understand that the best parts of a New England summer happen outside, whether it’s relaxing on the deck with a coffee, enjoying a family cookout, or kicking back after a day on the beach or boat. To truly enjoy your outdoor space, you need a deck that’s safe, durable, and designed to match the way you live.

At KB Carpentry, we design and build high-quality decks that transform backyards across South Eastern Massachusetts. Whether you need a brand new deck, a full replacement, expert deck repairs, or upgraded railings, we’re the deck contractor Marshfield homeowners trust for craftsmanship, communication, and long-lasting results.

Special Considerations for Your Marshfield, MA Deck

Whether your Marshfield home is steps from the ocean in Brant Rock, set near the Green Harbor Marina, or tucked into neighborhoods like Rexhame or Ocean Bluff, your deck should suit your lifestyle while standing up to the challenges of a coastal climate.

Living in Marshfield means dealing with salty air, shifting temperatures, and the occasional nor’easter, all of which can wear down traditional wood decking over time. That’s why many homeowners opt for composite decking from top brands like Trex and TimberTech. These materials are built to resist moisture damage, fading, and warping, making them a smart choice for homes with coastal exposure.

Wobbly railings, weathered boards, and hidden structural problems are common in Marshfield’s coastal environment. As a local South Shore deck contractor, KB Carpentry can handle everything from repairs to full resurfacing, improving safety and the look of your outdoor space. Whether your deck needs a quick fix or a major overhaul, we’ll evaluate the damage and guide you toward a practical, long-lasting solution.

If your home offers views of the ocean, the South River, or Marshfield’s namesake marshlands, cable railings are a great way to preserve those views. We can also add built-in lighting to boost visibility and create a warm, inviting atmosphere for evening gatherings. For homeowners who love to host, features like built-in benches or a screened-in porch can add comfort and help you make the most of your outdoor space.

At KB Carpentry, we understand what it takes to build a deck that matches your lifestyle and stands up to the elements. Let us help you create an outdoor space that’s both resilient and relaxing.

New Deck Installation

A custom deck adds valuable outdoor living space. At KB Carpentry, we start by learning how you plan to use your outdoor space, and then design a deck that fits your goals. We offer low-maintenance composite deck materials like Trex and TimberTech, along with custom touches like lighting, built-in seating, and railings, so your deck looks great and holds up over time.

Deck Replacement

If your deck is worn out or no longer suits your needs, we can replace it with something safer and more functional. Now is the time to consider some upgrades. A new layout, better stair placement, or improved views can make a big difference to your lifestyle. We’ll assess the design of your current deck and help you decide what changes make sense, then build you a replacement deck that’s engineered to last.

Deck Repairs & Resurfacing

Marshfield’s coastal climate can wear down your deck over time, leading to issues like warped boards, rusted fasteners, or shaky railings. At KB Carpentry, we provide detailed deck inspections to assess the damage and recommend whether surgical repairs or full resurfacing is the right move. Deck resurfacing is a budget-friendly option that gives your deck a fresh new look while keeping the existing structure. It’s also a great time to upgrade your decking material, install better railings, or add features like lighting and improved access for safety and convenience.

Deck Railings

Railings are essential for both safety and style on any South Shore deck. From sleek cable railing systems that keep your view open, to durable aluminum options for poolside use, or low-maintenance composite railings that hold up in coastal conditions, we’ll help you find the best fit for your home. Every deck we build includes new railings, but we also offer railing upgrades on their own if yours are outdated, damaged, or no longer meet your needs. Railings are a key safety feature, so we never skimp on quality.

Porch Builder

Looking for a way to relax outside without dealing with bugs or bad weather? A screened-in porch lets you enjoy the outdoors in comfort and style. We can customize yours with thoughtful touches like fans, lighting, and detailed finishes that make it feel like a true extension of your home. Prefer a more timeless look? A farmer’s porch adds classic charm and curb appeal while creating a welcoming space to kick back. Get in touch with KB Carpentry to bring your ideal porch to life.

Frequently Asked Questions About Our Deck Services

Yes! KB Carpentry is based in Plymouth, MA so you can think of us a deck contractor near you. We service a 45 minute driving radius around Plymouth, which includes Marshfield, MA. We build lots of decks on the South Shore and would love to give you a quote.

Most towns, including Marshfield, require permits for new deck construction or major deck replacements. Simple deck repairs, resurfacing projects and railing installation generally do not require a permit. As a full-service deck contractor, KB Carpentry handles the permitting process for you to ensure your project meets all local building codes and regulations.

Absolutely. First we will start with a structural deck inspection. If your current deck’s structure is sound, we can replace old boards, update railings, and refinish the deck surface to make your deck look brand new. If your frame is compromised, we may recommend a full replacement for safety and durability.

The best material is the down to your needs and your budget. With New England’s harsh climate, we usually recommend low maintenance composite deck materials like TimberTech, but some of our customers prefer the classic look of stained wood—or for the budget-conscious homeowner, pressure treated wood is a tried and true option.

Yes. Deck railings are an essential part of any deck, and are important for safety, especially if you have a pool deck. We can replace your deck railings as a standalone service, whether you want to upgrade to cable railings to enhance your view, install aluminum railings for durability, add composite railings for lower maintenance, or use wooden railings for a classic look.

We carry all necessary insurance, as well as a MA Home Improvement Contractor License (#183941) and a MA Construction Supervisors License (#CS-108509), so you can be confident that your project will be completed to the highest standards.
