Mitcham gardens deserve surfaces that cope with year-round use and still look smart. We design and install premium composite decking for homes across CR4, including projects near Mitcham Common and Figges Marsh. Composite boards give you the look of timber without the constant sanding and staining. Expect clean lines, safe edges and a deck that’s made for entertaining.
As composite decking contractors Mitcham area homeowners rely on, we tailor builds to local property styles—Victorian cottages with compact courtyards, 1930s semis needing family-friendly zones, and modern estates wanting seamless indoor-outdoor flow. We’re based just 10 minutes away, so surveys and follow-up visits are quick to arrange. Whether you want a simple platform or a multi-level deck with steps and seating, we size it to your lifestyle and garden proportions. Finishes are chosen to complement brickwork, render and existing patios.
Our process starts with a measured site visit, levels check and design options, then a clear written quote. We install a stable subframe, precise board spacing and hidden fixings for a sleek, screw-free look. Add-ons such as balustrades and built-in lighting are planned early, so cables and posts are neatly integrated. Every installation comes with a 10-year workmanship warranty, plus manufacturer warranties on composite boards for added peace of mind.
Mitcham gardens often have mixed ground conditions, from compacted soils near Mitcham Common to made-up ground around older plots. We assess levels, drainage and access before setting out the frame, and we plan deliveries to suit residential parking and narrower side passages. Where gardens sit higher than the house, we design steps and balustrades to keep routes safe. We also consider London Borough of Merton expectations on boundaries and overlooking when proposing raised platforms.
Rated 4.9/5 from over 280 verified reviews
In Mitcham, composite decking typically starts around £140–£220 per m² for supply and installation, depending on board grade and subframe requirements. Raised decks, complex shapes, multi-level layouts, and extras like balustrades, built-in lighting, seating and steps can take projects to £250–£400+ per m². Access, waste removal, and groundwork (levelling or drainage improvements) also influence the final budget.
Most composite deck builds take 2–5 days once materials are on site. A small, straightforward platform can be completed in a couple of days, while multi-level decks with steps, seating, balustrades and lighting often take 5–10 working days. Timescales depend on ground preparation, the amount of cutting and detailing, and access for moving materials through side paths or around existing landscaping.
Many garden decking projects are permitted development, especially when the deck is low and doesn’t significantly raise ground levels. However, rules can change if the deck is high, close to boundaries, affects drainage, or the property is listed or in a restricted area. We’ll advise during the survey and can help you check London Borough of Merton guidance before work starts, so the design stays compliant.
We provide a 10-year workmanship warranty on our composite decking installations, covering issues related to fitting, fixings and construction of the deck structure when used normally. Composite boards also come with manufacturer warranties, which vary by product and can cover staining, fading or material defects for longer periods. We’ll explain what’s included, how to care for your deck, and keep documentation for your records.
You can choose from a wide range of colours and finishes, including grey tones, warm browns and contemporary charcoal, in grooved or woodgrain-effect boards. We can design picture-frame borders, diagonal patterns, and multi-level layouts with integrated steps and benches. For raised areas, we recommend matching balustrades, and we can add low-glare built-in lighting to steps and edges. We’ll bring samples and help you pick options that suit your home and garden.
