Hiring a contractor

How to Choose a Building Contractor in Johannesburg

By Home First Creations

Before you sign, ask for five things: an NHBRC registration number you can check against the company name, a written scope that lists what is included and excluded, the name of the person who will supervise your site daily, a payment schedule tied to completed stages rather than dates, and two references you can phone plus one live site you can walk. A building contractor in Johannesburg who cannot produce those quickly is telling you something. These checks cost nothing and protect more money than any discount on a quote.

The rest of this page explains what each one looks like in practice on a Gauteng site, and which paperwork to keep. Where a requirement is legal or registration-related, confirm the current position with the relevant authority — rules and thresholds change, and the answer should come from them, not from a contractor's sales pitch.

1. Verify NHBRC registration and home enrolment

The National Home Builders Registration Council (NHBRC) registers home builders, and a home is meant to be enrolled with the council before construction starts. Registration alone does not protect you. Ask for the number, check it against the company name on the NHBRC's own records, and then ask for the enrolment certificate that carries your project address and your name as the client.

Enrolment is what links your house to the council's inspection regime and its home building warranty scheme. It is normally a costed line on the quote. If nobody mentions it, ask why, and if a contractor offers to skip the paperwork to save you money, treat that as a reason to keep looking. Requirements, fees and thresholds change, so confirm the current position directly with the NHBRC rather than relying on what any contractor tells you.

What to ask for in writing

  • The NHBRC registration number, printed on the quote and the contract — not just mentioned in a WhatsApp voice note.
  • Independent confirmation that the number belongs to the company you are paying, not to a related business.
  • The enrolment certificate for your stand before the builder takes over the site.
  • Who carries the enrolment fee, and when it is paid.

Not every job falls under home enrolment. Alterations, smaller renovations and commercial buildings sit under different rules, and the line is not always obvious to a homeowner. Ask the contractor what applies to your project, then confirm it with the NHBRC or your local authority. A builder who answers that question clearly usually answers the rest clearly too.

2. Get the scope in writing, including what is excluded

A quote is a number. A scope is the document that decides whether that number means anything. Ask for a schedule of works with measured quantities, product specifications and clear responsibility for supply and installation — the tile range and size, the sanitaryware model, the roof sheeting and insulation, the window system, the ceiling and cornice type, the paint system.

The exclusions list matters as much as the inclusions

Most unpleasant surprises on a Johannesburg build come from work that was never in the price. Ask each bidder to list exclusions explicitly rather than leaving blanks, and check these usual suspects:

  • Professional fees for architect, engineer or energy calculations, and municipal plan submission fees.
  • Bulk earthworks, retaining walls and unusual foundation conditions found after excavation.
  • Municipal water, sewer and electrical connections, meters and deposits.
  • Temporary services — site toilet, water, electricity, scaffolding hire and site security.
  • Rubble removal and builders' cleaning at the end.
  • Paving, landscaping, boundary walls, gates and pools.
  • VAT, and whether the quoted figure includes it.

Allowances, substitutions and drawings

Allowances are placeholders, and the final account is where they get settled. Ask for the rand amount of each allowance, what happens if you spend more or less, and how the contractor prices a substitution you request mid-build. Then make sure the drawings referenced in the quote carry a revision number, that the structural design matches those drawings, and that both are attached to the contract as annexures. Three quotes only compare fairly if all three price the same schedule and the same drawing revision.

3. Find out who is actually on site every day

Ask for the name of the site manager, how many days a week that person is on your site, and whether the crew is employed by the company or brought in per trade. The person who sells you the job is often not the person who runs it, and on a busy contractor's books your house may be one of several running at once. That is normal, but you should know who is accountable when two projects compete for the same bricklaying team.

Good daily supervision looks unglamorous and specific. It means someone checks setting out and levels before excavation is signed off, spacing and cover on reinforcement before a slab is poured, damp course and brick ties as walls rise, roof tie-downs and bracing, plumbing falls before screed goes down, and waterproofing before a single tile is laid. It also means the supervisor walks the site with a checklist, photographs stages before they are covered up, and holds a short weekly site meeting with you.

Signals worth noticing

  • You are given one named contact who answers on site, not a rotating set of numbers.
  • Inspection stages are written into the programme, so work is checked before it is hidden.
  • Progress is reported with photographs and simple notes rather than vague reassurance.
  • The supervisor can explain the sequence of trades and what happens if one runs late.

Home First Creations runs project management with daily on-site supervision, and turnkey work covers site preparation and soil poisoning through to finishing and handover — which is the part of the process most homeowners underestimate until the ground is open.

4. Agree payment stages, and never pay the full amount upfront

A deposit for mobilisation and materials is normal practice. Paying most or all of the contract value before work has been done is not. Structure payments against completed, inspectable stages — foundation and surface bed, walls to plate height, roof, plaster and screed, finishes, practical completion — and make each stage defined well enough to see and measure.

Practical rules that hold up

  • Pay into a business account whose name matches the contracting company, not a personal account or a third party.
  • Insist on a tax invoice for every payment and keep transfer proofs in one folder.
  • Do not pay for materials that are not delivered on site, or for work you have not seen completed.
  • Agree a snag period and a retention held back until the snag list is closed, in writing, before you start.
  • Never sign a contract and pay a deposit in the same meeting while the documents are still being "finalised".

Be careful with words like "discount for cash upfront" or requests to settle the whole balance to "lock in material prices". If a contractor genuinely needs early material payments, the request should be for specific items with delivery notes attached, inside an agreed schedule. Anything looser puts the risk on you. Every variation should also be priced and signed before the work happens, never settled verbally on site.

5. Insurance, health and safety, and BEE certificates for commercial work

For a home build, ask for a broker's letter confirming public liability cover is in force and that it applies to construction work, plus proof of cover for the subcontractors who will be on your site. Ask who insures the works themselves while they are in progress — the owner, the contractor, or both. For anything larger, ask for a letter of good standing for compensation of employees, and confirm with your own insurer that your policy expectations match what the contractor carries.

On health and safety, the useful question is not whether a file exists but who runs it. Ask for the name of the responsible person, how workers are inducted, what personal protective equipment is issued, and how scaffolding, edge protection and working-at-height are handled. A site where nobody wears a hard hat on a Monday morning has a supervision problem before it has a safety problem.

Paperwork for commercial and tender work

  • BEE certificate or sworn affidavit, current and in the company's registered name.
  • Tax compliance status PIN, which a client can verify online rather than trusting a photocopy.
  • Company registration documents and, where relevant, professional registrations for engineers or quantity surveyors.
  • Public liability cover and, for occupied buildings, confirmation of how the site will be separated and secured.
  • Health and safety file with appointments, risk assessments and incident reporting arrangements.

Procurement scorecards, insurance requirements and municipal conditions vary by client and by project, so confirm what your specific job requires with the relevant authority, your insurer or your procurement team rather than assuming a standard list. Home First Creations holds NHBRC registration, BEE compliance, public liability cover and a health and safety focus, and works with a vetted supplier and subcontractor network — details like these are worth checking on paper, not taking on trust.

6. Visit a live site and check references that match your project

Photographs on a website show finished work; a live site shows how a company behaves while the money is being spent. Ask to visit a project that is mid-construction, on a normal working day, and walk it slowly. Look at housekeeping and waste, whether materials are stacked off the ground and covered, whether there is a site toilet and running water, how finished work is protected, and whether anyone is actually supervising the crew.

Then ask for two references from projects similar in type and size to yours, completed in the last two to three years, and phone them. The questions that reveal the most are about money and behaviour after handover: did the final account resemble the quote, how were extras handled, how long did the snag list take to close, and would they use the same contractor again. A reference who only talks about how nice the team was is not telling you much.

Useful things to look at on a site visit

  • Brickwork lines, joints and lintels — straight and consistent, or patched and corrected after the fact.
  • The state of the temporary services and the site office, which usually mirrors the standard of the finishing.
  • Whether the person in charge can answer questions about the current stage without phoning someone else.
  • How the contractor handles a small problem you raise during the visit.

Home First Creations has operated since 2015 and has completed more than 250 projects across Johannesburg and Gauteng, from turnkey homes and commercial buildings to complex painting and maintenance work. A completed portfolio is worth reviewing alongside a site that is still open, which is why we would rather show you both.

7. Read the programme, and agree how variations are handled

Ask for a programme, not a completion date. A usable programme lists the sequence of work, the hold points where inspection happens, and a realistic allowance for rain and for municipal approvals. Then ask how many other projects the company will be running at the same time, because labour and supervision get shared whether or not the paperwork admits it.

Variations: priced, signed, then built

Every project changes. The question is whether the change is written down before the work is done or argued about at the end. Agree a simple procedure at the start: a written instruction, a price before execution, a stated effect on the programme, and one named person on each side who is allowed to approve it. Keep a running variation register so the final account is a total of agreed items rather than a surprise.

  • Ask what rates apply to common extras — extra tiling, additional power points, upgraded finishes.
  • Confirm that no verbal instruction on site is binding until it is confirmed in writing.
  • Agree what happens to the programme and to the payment schedule when a variation adds time.
  • Ask for the variation register at each payment stage, so nothing accumulates unseen.

Inspections and the handover pack

Municipal and professional inspections happen at specific stages — foundations, drainage, roof structure — and the certificate of occupation is needed before you occupy. Establish who schedules these, who pays, and who holds the approved plans on site. At handover, ask for the documents that make the house yours in practice: as-built drawings, electrical and plumbing certificates of compliance, glazing certificates, engineer's certificates where design required them, the NHBRC enrolment reference, and the maintenance instructions for finishes and waterproofing.

Questions to ask any building contractor in Johannesburg

Take this list to the first meeting. The answers matter less than whether they arrive quickly and in writing.

  • What is your NHBRC registration number, and will my home be enrolled before you start?
  • Which items are excluded from this price, and what is the rand value of each allowance?
  • Who is on site daily, and how do I reach that person?
  • What are the payment stages, and what percentage is held back until snags are closed?
  • Can I see proof of public liability cover and your health and safety arrangements?
  • Which projects like mine can I visit, and which clients can I phone?
  • What does the programme look like, including inspections and rain allowance?
  • How do you price a variation, and who signs it off?
  • Which certificates and drawings do I receive at handover?
  • What happens if the programme slips — who tells me, and when?

Where to take this next

Work through the five checks before you compare prices. A contractor who supplies the registration number, the written scope, the supervisor's name, the payment schedule and a site you can visit is a contractor you can hold to account. You can see what we build on our construction services page, look through completed work in our portfolio, and read how we run projects on the Why Choose Us page. When you are ready with a scope or even a sketch, send it through the contact page and we will tell you what we would need to quote on it.
