Decking Minster

Position the terrace before choosing boards

Set out furniture and the route to the lawn, gate or shed. Allow space to move around occupied chairs, open doors and use the terrace without narrow bottlenecks.

Show thresholds, slopes and the ground at the intended step landing. A deck can connect different garden areas, but the supporting design and safe transitions need planning before the surface is fitted.

For your Minster enquiry, include the access route for long boards and frame materials. Restricted gates, passages and turns can affect removal and construction even where the deck itself is small.

Timber or composite: compare the actual product

Timber offers natural grain and a finish that changes with weathering and care. Compare the specified timber, treatment and recommended maintenance rather than assuming all wooden boards perform alike.

Composite ranges vary in appearance, dimensions, fixing systems and care requirements. Check samples, technical instructions and warranty conditions for the actual range proposed.

Neither material removes the need for a suitable frame, drainage and appropriate fixings. Discuss texture and wet-surface information as well as colour, and consider the exposure where the terrace will sit.

What is the best thing to put under decking?

The space beneath needs suitable support and a route for water, with ventilation and access considered. Specify the frame and supports for the ground, deck height, loading and selected boards.

Ground preparation, a suitable geotextile or aggregate layer may form part of the proposal where they have a defined purpose. They are not a universal substitute for drainage or a structurally suitable base.

Keep soil and debris from creating unsuitable contact with the frame. Agree the construction beneath the boards, not just a promise to add a weed membrane.

Replacing boards does not automatically mean retaining the frame

Assess the existing frame, supports and connections before deciding what can stay. A surface that looks worn can conceal deterioration beneath it.

Changing board type may require different support spacing, fixings and movement allowances. Existing construction needs to suit the replacement product, not merely fit beneath it.

Show the old deck from above and any safely visible underside. Include soft boards, movement, damaged steps and areas where water or debris collects.

What is the 30cm rule for decking?

Planning Portal’s England decking guidance includes a height limit of 30cm above ground within its permitted-development conditions. Height alone is not the whole test.

The guidance also addresses coverage with other extensions and outbuildings, position relative to the principal elevation and restrictions affecting designated land or listed buildings. Some property types and removed development rights have different requirements.

Check the proposed terrace and related works with Thanet District Council where needed. Sloping ground, raised areas and changes to the wider garden should be included in that assessment before construction starts.

What does decking cost per square metre?

The complete price includes more than the boards. Area, preparation, frame, supports, fixings, steps, edges, balustrades, removal and access can affect the total.

For illustration, a hypothetical complete quotation of £3,000 for 20m² averages £150/m². This demonstrates a calculation, not our rate or a Minster market estimate.

Compare quotations for the same product and construction. Confirm VAT, waste removal, finishes and any exclusions. A supply-only board price cannot establish the fitted terrace cost.

What is the best decking preserver?

Choose a treatment compatible with the exact timber and its existing finish. A preservative, stain and decking oil serve different purposes; a single product is not automatically best for every deck.

Follow the timber or coating supplier’s preparation, application and drying guidance. Ask whether newly treated boards need a particular period before another finish is applied.

Composite boards have their own cleaning instructions and should not automatically receive timber treatments. Confirm the product before buying a coating, especially if warranty conditions are relevant.

Steps, edges and garden connections

Plan how people enter and leave the terrace, including steps, landings and edge protection where required. Agree these with the height and intended use rather than adding them after the boards are laid.

Coordinate the deck with patio paving, garden fencing and walls or raised beds if these form part of the same project.

Care for the finished terrace

Remove debris, keep drainage and ventilation routes clear and follow the selected product’s cleaning advice. Timber and composite both need care, even where their routines differ.

Inspect visible fixings, steps and edges as part of normal upkeep. Report movement or damaged components rather than concealing them with a surface coating.

At handover, clarify treatment or cleaning, return to use and the written product and workmanship terms.
