Deck Painting in Surrey

Surrey Decorators provide deck painting services covering properties across the Elmbridge borough and surrounding Surrey areas.
What we cover:
- Decking boards and surface treatment
- Balustrades and steps
- Handrails and safety finishing
- Deck staining and colour options
- Anti-slip finishes
Large detached homes on generous plots in Cobham, particularly along Plough Lane and Anyards Road, often have substantial hardwood or softwood decking attached to rear extensions. South-facing decking in Surrey accumulates algae and green mould over winter. Thorough cleaning and mould treatment are needed before any new paint or oil is applied.
Raised timber decks on properties backing onto the Thames flood plain around East Molesey and West Molesey collect standing water. They develop algae growth faster than inland properties. Mould treatment is applied before sanding to prevent the treated surface reinfecting.
Cobham and Esher garden decking in good structural condition typically costs £400 to £900 to clean, treat, sand, and recoat, depending on deck area.

Deck Painting Services
From decking boards to balustrades and handrails, we provide thorough preparation and protective finishes for every part of your deck.
Decking Boards and Surface Treatment
Decking boards accumulate algae and mould in Surrey’s damp winters. Thorough cleaning with mould treatment is carried out before applying protective finish.
Softwood decking requires a penetrating finish that allows moisture to escape. Hardwood decking accepts surface finishes or oil treatments depending on your preferences.
See our exterior painting page for complementary exterior work guidance.
Balustrades and Steps
Deck balustrades and steps receive the same thorough preparation and protective finish as the decking boards. Safety is paramount on elevated structures.
Anti-slip finishes are available for steps and high-traffic areas. For timber structure finishing elsewhere on your property, see our fence painting page.
Handrails and Safety Finishing
Handrails receive specialist preparation and finish application to ensure durability and safety. Finishes appropriate to the rail material and exposure are used.
Deck Staining and Colour Options
Decking can be stained in a range of colours from natural wood tones to contemporary colours. Your decorator advises on colours that age well and hide dirt effectively.
Semi-transparent stains show wood texture while opaque stains provide uniform colour.


Here’s How It Works
1. Decking Assessment and Cleaning
Your decorator visits, assesses the decking condition, checks for algae and rot, and plans the mould treatment and finish approach. Colour options are discussed.
2. Cleaning and Mould Treatment
Decking is cleaned thoroughly to remove algae, dirt, and mould. Mould treatment is applied and allowed to work before rinsing.
3. Drying Period
Cleaned decking is allowed to dry fully before finish application. Depending on weather, this may take several days.
4. Finish Application
Protective finish is applied to decking boards, balustrades, steps, and rails. Multiple coats may be needed depending on wood type and chosen finish.
5. Curing and Final Inspection
Decking is allowed to cure before returning to use. All surfaces are inspected before confirming the job is complete.
Deck Painting Costs in Surrey
Prices below are estimates only. Every deck is different. Call 01483 930151 for a precise quote.

Cost Factors
Deck finishing typically costs between £20 and £40 per square metre for labour and materials combined.
Three things drive the price:
- Deck area. Larger decks cost more in total but less per square metre than small decks.
- Surface condition. Decks with significant algae or mould growth require more preparation time.
- Finish choice. Oil treatments are the most economical. Solid stains cost more but provide more uniform colour.
Typical Price Ranges
- Small deck (softwood, 20 to 30 square metres, standard prep): £480 to £750.
- Medium deck (hardwood or large softwood, 40 to 60 square metres, significant preparation): £1,000 to £1,800.
- Large deck (80+ square metres, multiple surfaces, steps and balustrade): £2,000 to £3,500+ depending on condition and finish choice.
