Hot Tub Decking, Borehamwood: specification-led spec for mix of post-war terraces
If you're weighing hot-tub decking for a property in Borehamwood, the first thing that matters is load ratings, access panels and long-term finish — not the material choice. Once that's settled, Trex or Q-Deck composite for a wet, chlorinated environment is where most of our hot-tub decking work in WD6 lands, with yellow balau hardwood for a natural finish that handles moisture as a considered alternative. Recent work on Furzehill Road and Brook Road. We orient jobs off Meadow Park (Boreham Wood FC). Shenley Road frontage with driveway gate. Hardwood double gates with manual drop bolt, picket flanking panels. Replaced rotten softwood originals; sized to existing brick piers.

How we build hot-tub decking in Borehamwood
150×47mm C24 joists at 300mm centres over doubled bearers under the tub footprint; hot-tub area calculated to 400kg/m² loaded. On Borehamwood jobs we adjust for limited rear access on the older estates means materials usually have to come through the house.
Property mix locally: mix of post-war terraces, 1960s low-rise estates and new-build apartments near the studios. Typical gardens: small to mid-size rear plots, often south-facing on the Elstree side. Postcodes we regularly service: WD6.
Common failure modes on hot-tub decking
