Cracks & Structural Repair
Structural audit for old houses — know how safe your home is
A detailed engineering inspection of your building’s condition, with a clear report on risks, repairs and whether to renovate or rebuild.
Before you renovate an old house, add a floor, or buy a resale property, you need to know the condition of its structure. Paint and tiles can hide a lot.
A RennovEN structural audit inspects foundations, columns, beams, slabs and walls, and gives you a written report: what is sound, what needs repair, and how urgent it is.
Signs you need this
- Your house is over 20–25 years old
- You plan to add a floor or renovate heavily
- You are buying a resale independent house
- You see cracks, spalling or sagging
The RennovEN promise
- 10-year warranty on all works
- Itemised pricing, approved before work begins
- One accountable team across every trade
- Residential specialists — homes only
Diagnosis
Why it happens
Ageing materials
Concrete carbonation and steel corrosion progress silently over decades.
Undocumented changes
Past extensions and wall removals may have altered load paths.
Deferred maintenance
Years of leakage accelerate structural deterioration.
