Decking in Surrey

Treat garden decking as a structure, not only a finish.

Deck boards are supported above the ground, so the unseen frame, foundations, ventilation and water movement matter. Record the intended height, steps, balustrades, daily use and how much maintenance you will actually accept.

Layout

Set the platform height from the site

Decking can create a level outdoor area where the garden falls away or doors sit above the ground. Finished height affects privacy, steps, guarding, the view into neighbouring land and possible planning controls.

Mark the intended footprint and furniture before deciding board direction or colour. Include routes through the garden and access to drains, meters or other items that may need maintenance.

  • Finished height at every edge
  • Steps, ramps and guarding
  • Door thresholds and ventilation
  • Access panels and service routes

Structure

Ask how the frame will stay stable and dry

Ground support, spans, fixings and lateral stability need a site-specific design. Timber should be detailed to manage moisture and allow inspection; composite products need the spacing, support and fixings required by their manufacturer.

Water and debris should not be trapped against the house or beneath an inaccessible platform. Existing damp, poor drainage or unstable ground should be raised before the frame is specified.

  • Foundation or support method
  • Joist material, centres and protection
  • Ventilation and drainage below
  • Fixings, trims and access for inspection

Material

Compare whole-life behaviour, not a generic label

Timber species, treatment and grade influence appearance and care. Composite boards also vary in composition, profile, surface temperature, expansion, grip and warranty terms. Ask for the exact proposed product rather than accepting ‘premium composite’ as a specification.

All outdoor surfaces need cleaning and inspection. Discuss algae, staining, scratches, colour change, board replacement and the availability of compatible components.

Quote

Define what removal and making good include

Replacement decking can reveal weak supports, buried waste or poor drainage. A quote should say what assumptions have been made and how unforeseen defects will be handled.

State whether old materials are removed, planting is protected, electrics or lighting are included, and adjacent paving or lawn will be made good.

  • Demolition and disposal
  • Complete frame and board specification
  • Steps, rails, fascias and access hatches
  • Lighting, making good and exclusions

Work that affects this job

Resolve adjoining work before finished surfaces go down.

Drainage, levels, access, planting, boundaries and services often cross from one trade package into another. Planning them together can avoid lifting or damaging completed work.

Patios

Compare a paved terrace with a raised platform.

Landscape design

Resolve levels and layout before choosing a system.

Fencing

Coordinate privacy, boundaries and balustrades.

Landscaping

Integrate the deck with the wider garden.

Before anyone prices the work

Questions worth settling early.

Is composite decking maintenance-free?

No. It avoids some timber maintenance but still needs cleaning, ventilation, inspection and care. Product behaviour and warranty conditions vary.

Does raised decking need planning permission?

Height, location, property status and the overall proposal can matter. Check the Planning Portal and the local planning authority for the exact address before relying on a general rule.

Why is ventilation important below decking?

Air movement and drainage help limit persistently wet conditions around the frame and building. The detail depends on the structure and site.

What should I compare between installers?

Compare the frame, supports, fixings, board product, drainage, steps and guarding, access, waste, programme, warranty responsibility and exclusions.
