Frequently asked questions
- What is remedial building work?
- Remedial work is repair and rectification of existing buildings, fixing leaks, failed waterproofing, concrete cancer, balcony issues, structural movement, render damage and similar defects. It restores the building rather than changing how it's used.
- Do you do strata remedial work in Sydney?
- Yes. We work directly with strata committees, building managers and owners across Sydney on balcony rectification, waterproofing, concrete repair and façade work.
- How do I know if I have a waterproofing failure?
- Common signs are bubbling paint, damp smells, salt or efflorescence on walls, tile lifting in bathrooms, or staining on the ceiling below a balcony or wet area. We can inspect and report on what's actually causing it.
- Do you provide written scopes and warranties?
- Always. Every remedial job gets a written scope, supplier specs for membranes and repair products, and a workmanship warranty on completion.
