Tell us about the area, approximate size, preferred material, access and whether the deck forms part of a wider garden, patio, extension or refurbishment project.
Decking designed around the space and surrounding works
A suitable deck depends on the ground conditions, levels, subframe, drainage, access and chosen finish.
Discuss a decking project
Provide the main project information below.
Decking for gardens, terraces and outdoor living spaces
Decking can create a practical outdoor surface where gardens are uneven, where a terrace needs to connect with internal floor levels, or where a defined seating and entertaining area is required.
Crestane Construction can coordinate suitable decking installations across London for residential and selected commercial properties.
The correct build-up depends on the existing surface, ground levels, drainage, access, deck height, chosen material and how the deck connects with the surrounding building or garden.
For larger schemes, decking can be incorporated into wider external works alongside patios, paving, fencing, drainage, landscaping and refurbishment.
Decking installation tailored to the property
Suitable projects can range from straightforward garden decks to raised platforms and larger external works packages.
Timber Decking
Traditional timber deck installations for gardens, terraces and outdoor seating areas.
Composite Decking
Composite deck systems for clients looking for a contemporary, lower-maintenance finish.
Raised Decking
Raised deck structures where levels need to bridge between the property and garden.
Replacement Decking
Removal of unsuitable existing decking and replacement with a new deck system where appropriate.
Decking Steps
Steps and level changes coordinated with the deck layout and surrounding external works.
Balustrades & Edges
Suitable edge protection, balustrades and perimeter details where required by the project.
Deck Subframes
Supporting timber, composite or other appropriate framing built around the particular installation.
Garden Integration
Decking coordinated with patios, planters, fencing, paths and other external finishes.
Commercial Decking
Selected decking works for suitable commercial terraces and external refurbishment projects.
A good deck starts below the visible boards
The finished boards are only one part of a decking installation. The base, supports, subframe, ventilation, drainage and fixings all influence how the deck performs.
Crestane can coordinate the deck from preparation through to the finished surface, depending on the agreed project scope.
Where the deck connects to doors, walls, paving or drainage, those interfaces should be considered as part of the overall external design.
Contemporary decking with reduced routine maintenance
Composite decking is often chosen where clients want a consistent contemporary finish and reduced routine maintenance compared with many traditional timber products.
Different composite systems have their own board profiles, support spacing, fixing methods, edge details and expansion requirements, so the selected system should be considered when the subframe is planned.
Composite decks can be used for garden areas, terraces, extensions and selected commercial spaces where the chosen product is suitable for the application.
Colour, board width, grain pattern and trim details can all affect the final appearance.
Traditional timber decking for London gardens
Timber decking can provide a natural finish and can work well with gardens, planting and traditional property styles.
The timber species, treatment, board profile, fixing method and future maintenance expectations should be considered when choosing the final material.
Timber deck structures should also be detailed to avoid unnecessary moisture trapping and to allow suitable drainage and ventilation around the supporting frame.
Suitable replacement and new timber decking projects can be included within wider external works packages.
What can be included?
The final scope depends on the size, levels, material and surrounding garden works.
Clear and prepare the relevant area where included within the agreed scope.
Provide suitable support arrangements around the particular deck design.
Construct the supporting frame to the agreed dimensions and deck system.
Install the selected timber or composite decking finish.
Coordinate suitable access between different garden and deck levels where required.
Include suitable edge protection or balustrades where part of the design.
Complete fascia, perimeter and transition details around the deck.
Patios, paving, fencing and other external works can be coordinated within the wider package.
Levels, drainage and access should be considered early
A deck should work with the building and garden rather than create avoidable drainage, access or maintenance problems.
Ground & Levels
Existing slopes, surfaces and finished levels influence support requirements and the overall deck height.
Drainage & Ventilation
Water movement and ventilation beneath the deck should be considered when planning the build-up.
Property Interfaces
Door thresholds, walls, drainage points and adjacent paving need suitable detailing where the deck meets the property.
Decking can form part of a complete garden transformation
Many decking projects work best as part of a wider external plan rather than as an isolated platform.
Decking can be coordinated with paving, patios, fencing, garden walls, drainage, lighting, steps and landscaping to create a more complete outdoor space.
Crestane can consider suitable multi-trade external works where the project includes more than one element.
See our External Works London service for wider garden and external construction projects.
