Decking Installation in Linton

What decking installation covers

Installing a new deck means designing the structure for your garden, preparing the ground, setting foundations, building a pressure-treated subframe and fixing the decking boards. The finished result should sit level, feel solid underfoot and drain surface water away from the house. A deck built on poor foundations or with undersized framing will move, creak and deteriorate well before its time.

We install ground-level platforms and raised or split-level structures for gardens across the Linton area. Timber is still the most widely used material for residential decking in the UK, and treated softwood handles the job well when the right specification is used.

Repair or replace? How to think it through

This is the question most homeowners with an existing deck need to answer before spending any money. The honest answer depends on what has gone wrong and where. Replacing boards when the frame is rotten wastes money. Replacing the entire deck when only a handful of boards have split wastes money too. Here is how to judge it.

Start with the frame, not the surface

Lift a few boards if you can, or ask a contractor to do it during the survey. The joists and bearers are the load-bearing structure. If they are solid - no soft spots when you press a screwdriver into the wood, no visible rot at the ends or where they meet the posts - then the deck almost certainly has repair potential. If the frame is rotten or structurally compromised, the boards are largely irrelevant: the whole thing needs to come out.

When repair makes sense

Repair is the right call when the subframe is sound and the damage is limited to the surface or to isolated components. Common repair jobs include:

• Replacing a run of boards that have split, cupped or developed surface rot
• Re-securing boards that have lifted because fixings have failed
• Replacing a single joist or bearer that has rotted at one end
• Repairing or replacing a balustrade section that has become loose
• Treating and re-oiling or re-staining a deck where the surface coating has broken down

A repair job on a structurally sound deck is nearly always cheaper than replacement and can add several years of useful life. The key question is whether the frame will outlast the repaired boards. If the frame is ten years old and already showing early signs of wear, putting new boards on it may only buy you two or three more years before the whole structure needs to come out anyway.

When replacement makes sense

Full replacement is the right answer when the subframe is rotten or structurally unsound, when the deck was built to a poor specification and repairs are just delaying the inevitable, or when the original design no longer suits your garden. Some older decks were built with untreated timber, inadequate ventilation or joists spanning too far without intermediate support. These are not problems you can patch - the structure needs to be rebuilt from scratch to a proper standard.

Replacement also makes sense when the cumulative cost of repairs is approaching the cost of a new deck, or when you want to change the size, shape or level. There is little point spending money on a deck that will need another significant repair in two years.

A common mistake: treating surface problems without fixing what caused them

A common problem is blackening, slippery boards or surface rot that keeps returning despite cleaning and treating. The cause is almost always inadequate ventilation underneath the deck, or standing water that never fully drains. Replacing boards without addressing the drainage or ventilation means the same problem returns. Any repair job worth doing should include identifying why the damage occurred, not just fixing the visible result.

What a survey should cover

Before committing to repair or replacement, a proper survey of the deck should check:

• The condition of every joist and bearer, including the ends and any points where timber meets concrete or masonry
• The posts and how they are fixed into the ground (for raised decks)
• Whether the frame is level and whether it has moved since installation
• The fixings throughout - screws corrode in outdoor timber and lose their grip over time
• The condition of the ledger board if the deck is attached to the house
• Drainage and ventilation beneath the deck

Costs: repair versus replacement

Board replacement on a sound deck typically costs between £30 and £60 per square metre for treated softwood boards, plus labour. A full structural repair involving joist replacement will cost more, and the price depends on how many members need replacing and how accessible they are. Full deck replacement in treated softwood typically runs from £120 to £200 per square metre, supply and fit, for a straightforward ground-level structure. Replacement costs more upfront but often works out better value over ten years than repeated repairs to a deck that was not built well in the first place.

Timber and composite: does it change the repair or replace decision?

Composite decking boards do not rot or split in the same way as timber, but composite decking still sits on a timber or steel subframe that can fail. If you have composite boards on a failing timber frame, the decision is the same as for a timber deck: the frame drives the answer. Replacing the frame and relaying good composite boards is often worth doing. Installing new composite boards is a reasonable choice for a homeowner who wants lower surface maintenance going forward, though composite boards cost more than treated softwood at the outset.
