Hot Tub Decking, Islington: specification-led spec for Georgian terraces around Barnsbury and Canonbury
Capital Fencing installs hot-tub decking across Islington and out toward camden and hackney. What separates a hot-tub decking job from a standard boundary is the detail: raised composite deck sized to carry a 6-person hot tub filled with water plus occupants. That's the work, not the marketing. Recent work on Canonbury Road and Liverpool Road. We orient jobs off Highbury Fields. Canonbury Road front railings and gate. Wrought-iron replica gate hung on refurbished stone piers. Matched the original Grade II street profile.

Why this spec, for homeowners installing a hot tub who need the deck sized to carry the loaded weight
