Detached properties in Otford with south-facing timber decking receive significant sun exposure in summer, followed by wet Kent autumns. Untreated or poorly treated decking in this climate shows UV degradation and algae growth within two seasons. We clean back to the bare timber, treat biological growth, and apply the correct system before any finish coat goes on.

Deck Painting Services

South-facing decks in Otford and Seal can become slippery in autumn when algae builds up between coats. Anti-slip additive mixed into the topcoat creates grip without affecting the appearance significantly. We recommend this on any deck used by children or elderly household members. The finish is invisible at distance and adds no visible texture when viewed from a standing position.

Decking Boards

Decking boards are the highest-wear surface on any garden deck. Foot traffic, standing water, and UV exposure all degrade the timber surface over time. We clean boards thoroughly, allow full drying time, and apply either a penetrating deck oil or a pigmented deck paint. The choice depends on the timber type and condition. Hardwood boards in Otford and Hildenborough gardens respond well to oil treatments. Softwood boards on 1960s-80s properties in Swanley are better served by a pigmented deck paint that seals the surface.

Balustrades

Balustrade rails and posts are exposed on all sides. They dry out and crack faster than the horizontal boards beneath them. We treat each post and rail section individually, paying particular attention to end grain where moisture enters fastest. See our exterior painting page for further detail on timber finishing across the district.

Steps and Handrails

Steps on a domestic deck take concentrated impact in a small area. We apply a build-up finish to step nosings and high-traffic sections. This creates a protective layer that resists scuffing and reduces the rate of wear. Handrails are finished with a compatible topcoat to match the main deck colour.

Deck Staining

Staining preserves the visible grain of the timber while adding UV resistance and water repellency. It is well-suited to hardwood decks on period properties in Otford and Westerham where homeowners want to keep the natural timber character. We advise on colour and opacity level at the quoting stage based on existing stain, timber species, and deck age.

Deck Painting Costs in Sevenoaks

Overview

Prices below are estimates only. Every deck is different. Call 01732 440998 for a precise quote.

Deck painting costs in the Sevenoaks district typically range from £280 for a small softwood deck to £900 or more for a larger hardwood deck with balustrades and steps.

Three things drive the cost:

Deck size and complexity. A simple 15 square metre softwood deck costs significantly less than a 30 square metre hardwood deck with multiple levels and balustrade sections.
Condition. Decks with significant algae, UV damage, or failing previous coatings require more cleaning and preparation time. Boards with checks or splits need filling before a finish is applied.
Coating system. Penetrating hardwood oils cost more per litre than standard softwood deck paints. The right product for the timber type affects both the price and the final result.

Typical ranges:

Small softwood deck in Swanley or Borough Green, approximately 12-15 square metres: £280 to £420.
Mid-size softwood deck on a 1960s semi in Swanley, approximately 20 square metres: £380 to £580.
Timber deck on an interwar detached in Otford, approximately 20 square metres: £420 to £680 for clean, treat, and two-coat deck oil or paint finish.
Larger hardwood deck with balustrades on a detached in Hildenborough or Sevenoaks town: £650 to £950+.

Deck Painting FAQs

Do you treat and paint garden decking in Otford and the surrounding Darent Valley villages?

Yes. We regularly work in Otford and the Darent Valley, including Shoreham and Eynsford. South-facing decks in this part of the district see heavy sun in summer and significant moisture in autumn and winter. We use UV-stable deck oils or deck paints depending on the timber type.

What is the difference between deck oil and deck paint?

Deck oil penetrates the timber and feeds it from within. It keeps the grain visible and is well-suited to hardwood boards. Deck paint sits on top of the timber surface and provides a more opaque colour finish. It is better for softwood boards that have already been painted or are past the point of absorbing oil effectively. We advise at the quoting stage based on your specific deck.

How long does deck painting take?

A standard domestic deck takes one to two days, including preparation, treatment, and two coats of finish. Larger decks with balustrades and steps take longer. We confirm the timeline in the written quote.

How long will a deck treatment last before it needs redoing?

A properly applied deck oil on hardwood typically lasts two to three years before a maintenance coat is needed. A deck paint on softwood can last three to five years depending on UV exposure and foot traffic. South-facing decks in Otford and Seal will wear faster than sheltered north-facing ones.

Do you repair rotten boards before painting?

We do not carry out structural carpentry repairs. If we identify rotten boards during the assessment, we will advise you to have these replaced before we paint. Painting over rotten timber only accelerates the deterioration beneath the surface.

Can you remove algae from a green deck before painting?

Yes. Algae removal is a standard part of our deck preparation. We apply a biological cleaner, allow dwell time, and scrub or pressure wash the surface before any treatment goes on. Painting over algae without treating it causes new growth to push through within one season.

Do you use anti-slip additive on decks?

Yes. Anti-slip additive is available on request for any deck coating. We routinely recommend it for steps, and for any deck used by children or older residents. It does not significantly alter the appearance of the finish.

Do you paint composite decking?

Composite decking does not typically need painting in the same way as timber. If a composite deck has faded or is showing chalking, specialist composite deck paint or restorer can be applied. We assess composite decks on a case-by-case basis at the quoting stage.
