- London Clay Retention: Dense clay soils across St AlbansClick to open side panel for more information and ChelmsfordClick to open side panel for more information retain rainwater throughout winter, creating persistent groundwater pools that evaporate upward into subfloor timber joists.
- Subfloor Moisture Softening: Joists exposed to constant humidity absorb water over time, leading to timber softening, floor bounce, board squeaks, and damp smells indoors.
- Draft Siphoning & Heat Loss: Uninsulated subfloor cavities allow winter winds to pull interior room heat straight down through floorboards, forcing heating systems to run constantly.

3-Tier East of England Floor Insulation Standard
Tier 1: Timber Diagnostics & Subfloor Rot Fixes
Using non-destructive electronic moisture meters, our technicians inspect all structural floor joists beneath your home. Weakened or rotted timbers are cut out and replaced with pressure-treated structural timber, followed by an application of fungicidal decay barrier spray.
Tier 2: Rigid Foil-Faced Thermal Insulation Retrofit
We install high-density, rigid thermal insulation panels flush between floor joists. The reflective foil skin bounces indoor heat back up into your living spaces while creating an airtight seal against freezing ground drafts.
Tier 3: Chassis Anti-Corrosion Care & Re-Leveling
To ensure long-term stability on clay or alluvial soils, we remove flaking rust from steel chassis frames, apply a zinc-rich protective coating, and adjust chassis support jacks to eliminate floor bounce and squeaks.
