About us
One contractor, four trades, one contract
Most jobs on a building need more than one trade. Trinity exists so you are not the one coordinating them.
What we do
We carry out electrical, plumbing, carpentry and tiling work across Johannesburg — for homeowners, landlords, body corporates and commercial premises. A bathroom is the clearest example of why that combination matters: it needs a plumber, a tiler, an electrician and usually a carpenter, and the job normally goes wrong in the handovers between them.
Where a job needs one trade, it is quoted as one trade. Where it needs four, it is sequenced as a single programme with one person accountable for the result.
How we quote
From a site assessment, not over the phone. A price given before anyone has looked at the job has to carry enough margin to survive whatever turns up behind the wall — which means you pay for that uncertainty whether or not it materialises.
If something unforeseen appears mid-job, it is priced and approved as a variation before the work happens. The invoice is the quote plus what you signed off, and nothing else.
How a job runs
- 01
Site assessment
We come and look at the job. Quoting a rewire or a retile from a phone call means guessing, and a guess has to be padded to be safe.
- 02
Scope and quote
You get an itemised quote against a written scope, so it is clear what is included and what is not. Nothing starts before you approve it.
- 03
Schedule
We agree dates before we book materials. If access is restricted — an estate, a complex, a trading business — that gets planned in rather than discovered on the day.
- 04
Execute
The team works to the approved scope. Anything unforeseen is priced and approved as a variation before it is done, not added to the invoice afterwards.
- 05
Sign-off and handover
We walk the work with you against the scope, clear the site, and issue the certificates the work requires. The invoice matches the quote plus any variation you approved.
Standards and registration
Electrical and plumbing work in South Africa is regulated, and the registrations that matter are worth asking any contractor about — including us. Each service page sets out the standards that apply to that trade, and we will send any document you ask to see.
