Top Boat Carpentry & Woodwork Pros

If the teak planks are still in good condition but the caulking is cracked, shrinking, or pulling away, recaulking is usually sufficient and far more affordable. However, if the planks are thin (under 3/8 inch), soft in spots, or showing signs of rot, full replacement may be the better long-term investment. A marine carpenter can probe the deck and assess the core beneath to give you an accurate recommendation.

Teak is widely regarded as the gold standard for marine exterior woodwork due to its natural oils, durability, and resistance to moisture and decay. Mahogany, white oak, sapele, and douglas fir are also commonly used depending on the application and budget. A qualified marine carpenter will recommend the right species based on whether the wood is going above or below deck, and the environmental conditions it will face.

Minor rot that is localized can sometimes be treated and stabilized using epoxy consolidants and filler systems, which is significantly less expensive than full replacement. However, extensive transom rot that compromises structural integrity typically requires a full rebuild, which involves removing the fiberglass skin, replacing the wood core, and relaminating. A marine carpenter or boatbuilder should inspect and assess the extent of the damage before work begins.

A properly installed and maintained teak deck can last 20 to 30 years or more. However, frequent aggressive cleaning, excessive sanding, or neglected caulking can significantly shorten its lifespan. Regular oiling or sealing and prompt caulk repairs are the best ways to maximize the life of a teak deck.

Interior woodwork refinishing can dramatically transform the look and feel of an older vessel and is often one of the most cost-effective ways to improve a boat's value and livability. Stripping, sanding, and applying fresh varnish or oil finish to joinery, cabinetry, and trim can make a dated interior look nearly new. The return on investment is generally strong, particularly if the owner is preparing the boat for sale.

Oil finishes — such as teak oil or Danish oil — penetrate the wood grain and are easier to apply and maintain, but require more frequent reapplication and offer less protection against moisture and abrasion. Varnish forms a hard, protective film on the surface and provides superior protection and a high-gloss finish, but requires more preparation and skill to apply correctly. The right choice depends on the wood species, location, and how much maintenance the owner is willing to perform.

Yes — custom joinery is one of the most popular marine carpentry services, particularly for cruising and liveaboard owners looking to maximize storage. Marine carpenters can design and build lockers, berth bases, galley cabinetry, nav station desks, and more, all fitted precisely to the curves and dimensions of the vessel's interior. Marine-grade plywood, solid wood trim, and moisture-resistant hardware are typically used to ensure longevity in the boating environment.

Marine carpentry requires specialized knowledge of boat construction, marine-grade materials, and the unique demands of a saltwater environment — skills that most residential carpenters do not have. Look for professionals with a portfolio of marine projects, familiarity with boatbuilding epoxies and marine sealants, and ideally experience working on vessels similar to yours.
