Carshalton gardens deserve surfaces that look smart year-round and cope with busy family life. We install composite decking that complements everything from patios near Carshalton Ponds to larger lawns around Carshalton Beeches. Our boards resist fading and splintering, giving you a cleaner, safer space for dining, play and entertaining. Every deck is set out carefully for straight lines, neat edges and confident drainage.
Local homes in SM5 range from Victorian and Edwardian houses to 1930s semis and other period properties, each with different levels, thresholds and garden shapes. We’re used to working with narrow side access, existing steps, and changes in height that benefit from multi-level decking. For older properties, we can create a sympathetic transition from kitchen doors to garden, with matching steps and subtle balustrades. If your garden sits lower or holds water after rain, we’ll specify the right sub-frame and airflow.
We start with a site visit and design guidance, then provide a clear written quotation and schedule. Installation includes a robust substructure, precise board spacing, and hidden fixings for a premium finish. We can integrate seating, steps and built-in lighting so the deck works day and night. Homeowners choose us for reliable communication, tidy working practices, and a 10-year workmanship warranty alongside manufacturer warranties on materials.
As composite decking contractors in London Borough of Sutton, we plan for typical access and parking constraints on residential streets, especially around Carshalton and Wallington. We also account for gardens that slope or sit close to mature trees, which can affect levels and drainage. Our sub-frame designs allow airflow and stable support, helping prevent movement over time. Where neighbours are close, we schedule deliveries and cutting to minimise disruption.

In Carshalton, composite decking typically starts from around £120–£180 per m² for supply and install, depending on board brand, sub-frame requirements and access. Mid-range projects with steps, seating or balustrades often fall between £3,000–£8,000. Larger or multi-level decks with built-in lighting can be £10,000+. We’ll survey levels and ground conditions before confirming a detailed, itemised quote.
Most composite decks take 2–5 days to install once materials are on site. A small, straightforward platform can be completed in a couple of days, while multi-level layouts with steps, balustrades and lighting usually take 1–2 weeks. Timescales depend on ground preparation, whether old decking needs removal, access for materials, and any bespoke features such as built-in seating or complex edging details.
Composite decking is often permitted development, provided it doesn’t raise the ground level excessively and isn’t positioned in a way that conflicts with restrictions. However, rules can differ for listed buildings, conservation considerations, or where boundaries and overlooking are sensitive. We’ll flag likely issues during the site visit and can advise on Sutton Council guidance where relevant. If permission is needed, we’ll help you prepare the information required.
We provide a 10-year workmanship warranty covering installation issues such as fixings, alignment and structural integrity of the deck build. Composite boards also come with manufacturer warranties, which vary by product and typically cover performance aspects like rot resistance and excessive fading. We’ll explain what’s included before you choose materials and provide care guidance to keep your deck looking its best. Any snagging is handled promptly and professionally.
You can choose from a range of composite board colours and finishes, including woodgrain and contemporary smooth options, with coordinating fascia and edging. We can install hidden fixings, add balustrades for raised areas, and build steps that match door thresholds. Popular upgrades include built-in LED lighting, integrated seating and multi-level decks to manage slopes. We’ll recommend layouts and products based on how you use the space and your home’s style.
