RennovEN Ensure: Construction Supervision
Construction material quality check — are you getting what you pay for?
We verify cement, steel, bricks, sand and fittings on site against the brands, grades and quantities in your contract.
Material substitution is one of the most common ways construction quality slips: a cheaper steel brand, under-strength cement, poor sand or second-grade bricks. From the outside, the finished house looks the same.
RennovEN Ensure checks deliveries and stock on site against your contract, looks at test certificates and identifies materials that need lab testing.
Signs you need this
- Contractor supplies materials in a lump-sum contract
- You can’t check deliveries yourself
- Unknown brands appearing on site
- Concrete or plaster looks weak or powdery
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
Brand substitution
Specified brands replaced with cheaper ones.
Wrong grades
Steel or cement of a lower grade than designed.
Poor storage
Cement stored damp or steel left to rust loses quality.
