Marine Sealant Replacement

Broken or mouldy seals really detract from your boats aesthetics . We can replace it to an OE specification.


We remove all traces of the old sealant bonding. We use honed techniques to do this without damaging the surrounding surfaces.


We use marine-grade, proven sealants on the area with precision masking and attention to detail. The end result looks OE specification.


The surfaces that need sealing require careful cleaning to remove any contaminants that may compromise the new sealant.

Sealant Replacement

Mouldy or failing sealant can really draw the eye aswell as cause havoc to interior spaces once water penetrates it. 

Drawing upon years spent building superyacht tenders and sportsboats with a UK boat builder, we can remove and replace almost any sealant to OE specification.

Damaged sealant is an inevitable part of a boat ageing; It’s what really makes a used boat look used.

We can draw on our years of boatbuilding experience to remove & replace any sealant that has failed. Too often we see DIY jobs that look tatty and rarely fix the problem long term…what we do is the polar opposite of that.

It’s all in the preparation as they say; careful removal, cleaning and re-application are vital to not cause damage to adjoining surfaces and to get the sealant to function as intended.

La Rever was cleaned and polished by South Coast Yacht Care and I have never seen her looking so good.

Considering she is now over 6 years old she actually looks better than when I first picked her up brand new. I highly recommend David Paxton and his team as they are perfectionists and the quality of their work is excellent. I feel like I’ve just got a brand new boat again! "

I cannot recommend South Coast Yacht Care enough.

They have always delivered a great service on time and at a reasonable price. David especially is very knowledgeable and was able to transform my boat with gelcoat renovation and a new set of modern stripes!



Boating without South Coast Yacht Care would be a chore!

They take away all of the headaches of owning a boat and make it a pleasure. I’ve recommended them to other boat owners within the Marina who have all had similar experiences.
