Building with confidence. Protecting what matters.
Greysand Builders keeps water out of buildings — and keeps plumbing and flooring work running smoothly, from the first site visit to long after handover.
— What we do
Three disciplines, one standard.
Every job — waterproofing, plumbing or flooring — runs through the same written, accountable process. Nothing changes but the scope.
Waterproofing
Roofs, basements, wet areas, tanks and balconies — sealed against water at the source, not just the symptom.
Plumbing
Reliable installation, repair and maintenance so systems perform behind the walls, not just on inspection day.
Flooring & Renovation
Quality flooring installation, repairs and upgrades built for everyday use — and the finishing work around it.
— What you get
A process built to remove guesswork.
A written site report
What we found, what's causing it, and photographic evidence — before we talk price.
A fixed, itemised quote
Materials, labour and timeline laid out clearly, so there are no surprises mid-job.
One dedicated contact
A single person accountable for your job from the first visit to the final walkthrough.
Follow-up after handover
A walkthrough, care notes for the finished work, and support if something needs attention.
— How a project runs
From first site visit to handover, in four stages.
Assess — Survey the site
We inspect the structure, trace the source of the problem and record what we find.
Plan — Recommend a fix
A written scope and quote, weighing materials, cost, time and durability.
Build — Carry out the work
Our crews execute to spec, with safety and site tidiness maintained throughout.
Protect — Hand over & support
A final walkthrough, care notes, and support if anything needs attention.
