Premium Composite & Timber Decking in Eltham
Specialist Millboard & Trex composite decking and timber installations built on engineered C24 subframes across Eltham SE9. Founder-led by Billy Maddox & Vincent O'Connell.
Engineered Decking Solutions for Eltham Properties
The Tree Amigos install composite decking in Eltham, SE9, using Millboard and Trex materials with a 25-to-50-year manufacturer warranty.
Decking provides a warm, versatile outdoor living platform that connects your home's rear doors with the garden. In Eltham, where properties near Eltham Palace, Well Hall Pleasaunce, Avery Hill Park, Coronation Green and Eltham High Street often feature spacious 1930s semi-detached and detached family homes, arts & crafts cottages, and expansive suburban garden plots, decking creates level, usable entertaining areas without the disruption of extensive excavations.
For larger Eltham family gardens, we design and build multi-tiered composite decks with integrated steps, flush lighting, and balustrades using 25-to-50-year warranty Millboard and Trex boards. At The Tree Amigos Landscaping & Gardening Ltd, every deck is constructed on a heavy-duty C24 strength-graded timber subframe, elevated on breathable geotextile membrane and structural pedestals to protect timber from Eltham's damp London clay soil.
Located just 10 minutes from our Woolwich headquarters via Academy Road and Well Hall Road, we provide fast response times and personal founder-led management for all SE9 projects.
