Complete Demolition Services Across Essex
Soft Strip & Selective Demolition
Ideal for fit-outs and refurbishments in Chelmsford High Street shops or Southend offices. Our teams remove internal walls, ceilings, M&E services and fixtures without touching the structural frame, handing you a clean shell ready for new trades.
Concrete & Structural Demolition
From reinforced floor slabs in Basildon's Burnt Mills estate to redundant silos in Colchester, we deploy high-reach excavators, hydraulic crunchers and wire-sawing for controlled, vibration-limited removal.
Emergency Demolition & Insurance Work
Fire-, flood- or storm-damaged buildings near the A127 can't wait. We provide 24/7 call-outs, make-safe works and liaise with loss adjusters to secure and dismantle hazardous structures fast.
Grab Hire, Muck Away & Waste Management
Euro 6 eight-wheelers with 7 m reach clear soil, hardcore and mixed waste the same day. All loads are ticketed and 95 % is recycled at our Rayleigh transfer station—supporting your BREEAM or WRAP targets.
Site Preparation & Landscape Grubbing
Tree-root grubbing, foundation breakout and bulk earthworks pave the way for new builds across Harlow, Brentwood and beyond. Add crushed-concrete backfill to close the loop and save on quarried aggregate.
Our Four-Step Demolition Process
Free Site Survey & Digital Scan
We capture laser-accurate point clouds, underground service traces and asbestos reports—essential data before the first bolt is loosened.
Precision Planning
A detailed RAMS pack (BS 6187 compliant) maps sequencing, traffic, dust and noise controls. You'll also receive a fixed programme with milestone sign-offs to keep other trades on schedule.
Live Safety Monitoring
QR-code check-ins, air-quality sensors and weekly independent audits protect your workforce and satisfy principal-designer duties under CDM 2015.
Waste Tracking & Sustainable Disposal
Every tonne is classified, segregated and barcode-tracked from site to facility. On completion we issue digital waste transfer notes and a recycling certificate—often hitting 97 % diversion from landfill.
