Decking Twickenham
Composite, timber, raised decking and full replacement.
Whether the brief is a dining space near the kitchen or a quieter seating area further down the garden, the layout should suit how you use it. Across Twickenham, St Margarets and Strawberry Hill, we offer new timber and composite installations and complete replacement projects.
New installations and complete replacements. We do not offer small repair jobs.


Composite decking in Twickenham
If regular oiling is a chore you would rather avoid, composite may suit your routine. It still needs cleaning. Timber offers natural variation and a different finish underfoot; choose it with a realistic plan for treatment and weathering.
Composite can reduce the regular staining or oiling associated with timber. It still needs cleaning, and the exact board range determines its finish, installation requirements and warranty. We discuss colour, surface, edge details and suitable supports as one specification.
Joist spacing, ventilation and expansion allowances must suit the selected product. New boards should not simply be fitted to an unsuitable old frame.
Compare composite materials and installation optionsTimber decking and a practical garden layout
Softwood and hardwood offer natural character, with different costs and care needs. Discuss the species, treatment and finish rather than treating every timber deck as the same product. Allow for future cleaning and maintenance when deciding what suits your garden.
Think about the route for bins, bicycles and garden equipment before fixing the deck outline. Keeping a practical clear route can be more useful than extending the boards to every boundary. Door swings and furniture positions belong on the same plan.
The survey considers drainage, thresholds, access to services and the supporting frame. Board direction and edge details can then be chosen to suit the layout.


Raised decking, steps and changing levels
Where a garden sits below the house, a raised platform can make the transition more comfortable. It also changes overlooking, edge protection and the load on the supports. Discuss those points before choosing balustrades or setting the final height.
A raised deck is a load-bearing structure. The proposal needs suitable foundations, supports, bracing and fixings, as well as a safe route on and off the platform. We identify where structural advice or other specialist input is needed before agreeing the work.
Planning, boundary and building requirements depend on the property and design. Balcony or roof-terrace work also needs attention to the existing structure, drainage and waterproofing. These checks should happen before construction.
Full decking replacement in Twickenham
If an existing deck needs replacing, we assess more than the visible boards. A complete project can address deteriorated supports, unsuitable spacing, drainage and the layout at the same time as choosing a new finish.
We do not undertake small repairs, isolated board changes, loose-fixing jobs or cosmetic restoration. Some local defects may be repairable, but that work falls outside our service. Steps and balustrades can be included in an agreed full installation or replacement.

A square-metre board price is only one part of the project. We provide a free, no-obligation quotation after discussing your requirements and assessing the site. The scope should make the following items clear.
Materials and frame
The exact boards, supporting specification, fixings, edge details and finish.
Access and removal
Delivery route, protection, removal of old decking and waste handling.
Levels and extras
Ground preparation, steps, balustrades and any specialist design or approval requirements.
Ask for VAT treatment, inclusions and exclusions to be explicit. For initial budgeting, use our timber and composite cost comparison and hidden-cost checklist. These are guides, not a quotation for your address.
1. Share your brief
Tell us the postcode, approximate dimensions, preferred use and any access issues. Photos of the garden and old deck help.
2. Assess and specify
We discuss materials, levels and structure, identify uncertainties and set out the agreed work in the quotation.
3. Agree the programme
Once the scope is accepted, agree access, timing and any required approvals before installation. Discuss care instructions at handover.
Decking questions in Twickenham
Which decking services do you offer in Twickenham?
We provide new composite and timber decking, garden layouts, raised structures and full decking replacements. Steps and balustrades can be included in an agreed complete project, subject to the site assessment and any necessary permissions.
Do you take on small decking repairs?
No. We do not undertake patch repairs, individual-board replacements, loose-fixing jobs or standalone restoration. Some local defects may be repairable, but that work is outside our service. We can assess and quote for a complete replacement.
Can you replace an old timber deck with composite in Twickenham?
Yes. We quote for the complete replacement and inspect the accessible supporting structure. Existing joists are not assumed suitable: spacing, condition and ventilation must suit the specified new boards.
Can the old frame be reused for a new deck?
It should not be assumed suitable. We inspect what is accessible and consider condition, spacing, fixings and ventilation against the new specification. Your replacement quote sets out the necessary structural work and any limitations before the old deck is removed.
What determines the installation price?
The area, chosen boards, supporting structure, access, removal, groundwork and finishing details all matter. Steps and guarding can change the scope considerably. We provide a project-specific quotation following assessment, rather than a small-repair price package.
Do I need permission for a raised deck?
This depends on the proposed design and property. Check height, boundaries and any planning restrictions before committing. Our planning guide gives a starting point; the relevant authority or a qualified adviser should confirm the position for your address.

Reviews for MJ Kloss Carpentry & Joinery — the master carpenters behind London Decking Specialists
See all reviews on GoogleWouldn't hesitate to recommend MJ Kloss Carpentry and will certainly be using them again. They have now completed two pieces of work for us and in both cases we've been delighted with the results. Carlos, their head carpenter, is a true artisan who takes the utmost pride in his beautiful work (as well as being a lovely person to have working in your home). Maarten, the project manager, is equally easy to work with. He skillfully helped guide us through the design process offering really creative and effective solutions throughout. Any issues (and let's face it, things will always crop up on any project, no matter who you work with) were thankfully minor and resolved quickly without complaint.
Very happy with the process to help me design what I was looking for (even before I knew what I was asking for) and the attention to detail with the installation was excellent.
Great experience. Delivered what we asked for and more, in a tidy and timely manor. Thanks!
