Suspended Timber Subfloor & Joist Repair in Bristol, Bath & North Somerset

Specialists in suspended timber subfloors

Many older homes in Bristol, Bath and North Somerset have suspended timber subfloors — particularly Victorian and Edwardian properties. Over time, joists can suffer from wet rot, woodworm or damp damage, leading to bouncy, creaking or unstable floors. Lucas Kane Carpentry specialise in diagnosing and repairing these problems, from single joist replacements to full ground-floor subfloor renovations.

What We Do:

We remove damaged or rotten joists and replace them with new pressure-treated structural timbers, properly secured and built to current building regulations. New timber floorboards are then fitted to restore your floor — keeping the character of your home while making it safe and solid underfoot.

Subfloor Ventilation & Damp Prevention:

Poor ventilation beneath suspended floors is one of the main causes of timber decay. As part of every job, we clear debris and rubble from the subfloor void, unblock, replace, install airbricks, where needed. This protects your new timbers and prevents future problems

No Job Too Big or Small:

We regularly carry out complete ground-floor subfloor renovations, but not every job needs that level of work. If the damage is limited to one area — a hallway, single room or even a section of a room — we can lift the flooring, replace the affected joists, and leave the rest untouched.
