Renewing an old boat's deck doesn't always mean an expensive job. We break down the real costs by option and explain how to do it without removing the original teak.
Over the years, a boat's original deck degrades: teak cracks, gelcoat loses grip, seams open up. Renewing it may seem like a major, costly job, but today there are options that transform the boat at a fraction of the traditional cost. Here we break down the numbers.
Option 1: restore the original teak
Sanding, recaulking and treating an old teak deck is possible, but laborious and expensive: between €3,000 and €8,000 depending on condition and size, and with a limited lifespan because the teak has already lost thickness. It will need maintenance again every season.
Option 2: replace with new teak
Installing new natural teak is the most expensive option: between €8,000 and €15,000 on a 12-metre boat, plus future maintenance. It is only justified on high-value classic boats with heritage value.
Option 3: marine foam deck
Here is the paradigm shift. Marine foam is bonded directly over the existing deck — without removing the old teak or gelcoat — and typically costs between €1,500 and €3,500 for that same 12-metre boat, installation included if you do it yourself. No construction work, no dust, no future maintenance.
How it's renewed without removal
- 1The existing surface is cleaned and lightly sanded to provide grip.
- 2Measurements are taken or plans sent; we design the pieces to scale.
- 3You receive the custom-cut, numbered pieces.
- 4They are bonded with marine contact adhesive in an afternoon.
