BUYING GUIDE · DECKING
How to choose the right decking for your garden
The best starting point is not a colour chart. It is a clear picture of how you want to use the space, what the site needs and what is included in a complete installation.
1. Draw the furniture before the perimeter
Decide whether the deck is mainly for dining, relaxing, reaching a garden room or combining several uses. Mark the furniture and allow space to pull out chairs, walk around a table and open nearby doors.
Then consider the route to the lawn, the best view and the parts of the garden you want to retain. This helps avoid a terrace that is large enough on paper but awkward once furnished.
Note changes in level, privacy, shade and the location of drains. Raised edges and steps belong in the first layout discussion rather than being added after the boards are ordered.
2. Compare the board construction
uPVC decking is a plastic system without timber fibres in the board. Wood-fibre composite decking combines wood fibres and polymers. Within both categories, profiles, finishes and fixing requirements vary.
Plastic boards without timber fibres. Compare the profile, finish and the complete fixing and support specification.
Wood fibres combined with polymers. Compare the core, capping, protected faces and the installation requirements.
Ask for the manufacturer and specific product. Check whether a composite is capped, which faces are protected, what the core construction is and what the warranty actually covers.
A premium finish may offer appearance or performance benefits that matter to your project, but the label alone is not a specification.
3. Look at samples beside the house
Compare samples in sunlight and shade, against existing brickwork, paving and window frames. Check grain, tonal variation and the appearance of board edges.
Think about the whole area. A dark sample may create a striking border but a very different effect across a large terrace. Board width, length and direction also influence the number of joints and the visual rhythm.
4. Ask what supports the surface
The subframe should suit the site, the board system and the intended loading. Confirm the supports, frame material, spacing, fixings, ventilation and drainage.
Do not assume an existing frame can be reused. Its condition, geometry and compatibility need checking. If a hot tub, large planter or pergola is planned, tell the installer before the design is finalised.
The installation guide explains why preparation and edge detailing are as important as fitting the boards.
5. Compare a complete quotation
| Preparation | Removal, waste disposal, ground preparation and access arrangements. |
|---|---|
| Structure | Supports, frame specification, drainage and service access. |
| Visible finish | Named boards, colour, fixings, fascias, borders and steps. |
| Additional work | Balustrades, lighting, structures and any specialist input. |
| Aftercare | Care instructions and separate product and workmanship terms. |
A board-only square-metre price leaves out much of the project. Compare the completed scope before deciding which quotation offers better value.
6. Be realistic about maintenance
Low maintenance is not no maintenance. Leaves, dirt and organic growth need removing, particularly in shaded areas. Follow the selected product’s cleaning guidance and check restrictions on pressure washing, coatings and detergents.
Consider furniture feet, cooking equipment and heavy objects before use. No outdoor surface should be treated as slip-proof in rain or ice.
Keep the named product details, care guidance and warranty information. Those documents are more useful for future questions than remembering only the board colour.
Bring the right information to your consultation
Share your postcode, photographs, approximate dimensions and the activities you want the deck to support. Mention the access route, changes in level and any future additions.
