Custom carpentry and built-in cabinetry are among the most visible and long-lasting investments a homeowner makes. A well-fitted kitchen or wardrobe adds property value; a badly executed one — doors that do not hang true, drawers that stick, cabinet boxes made from swelling particle board — is expensive to undo. Unlike a leaking tap you can ignore temporarily, bad carpentry is something you see and interact with every day. And unlike plumbing or electrical work, carpentry in South Africa has no mandatory registration body, which means the market is unusually open to operators who have basic tools but not the skill or materials knowledge to produce lasting work.
These are the warning signs to check before you sign anything or pay a deposit.
They Cannot Show You Previous Work to Inspect in Person
Photographs of completed joinery are easy to manipulate — flattering angles, ideal lighting, and taken before the client has lived with the furniture long enough for quality issues to emerge. The only meaningful evidence is work you can physically inspect: open the drawers, check whether doors hang true, look at join quality inside cabinets, press on surfaces to test rigidity, and examine edge finishing up close.
Ask any prospective carpenter to show you a completed installation you can physically visit. A carpenter with genuine pride in their work will show it off — it is their best sales tool. One who can only provide photos, or who claims previous clients are not available to be visited, may not have the track record the portfolio suggests.
They Cannot Specify the Materials They Will Use
The quality of built-in furniture is determined primarily by materials. The difference between 16mm chipboard, 18mm industrial board, 22mm MDF, and birch plywood is significant in durability, moisture resistance, and load-bearing capacity. Hinges also matter: Blum and Grass are reliable European brands with multi-year warranties; cheap unbranded hinges fail within months under regular use.
Request a written material specification before signing: board thickness, core material, facing material, hinge brand, and drawer runner system. For kitchens, ask whether kickboards, tops, and handles are included in the quote or are extras. A professional carpenter will produce this specification without hesitation — it is how they cost the job accurately. One who is vague about materials is either working from a generic template or hoping you will not notice the substitution.
The Quote Was Produced Without a Proper Site Measurement
Accurate built-in furniture requires precise site measurement — walls are rarely square, floors are rarely level, and ceiling heights often vary. A quote produced over the phone from approximate measurements, or after a cursory five-minute visit, will not account for the variables that determine whether the finished installation fits properly. Professional carpenters measure at least twice: once when quoting and once before manufacturing.
They also note structural details — whether walls are plumb, whether there are pipes or light switches affecting placement, whether skirting boards need to be accommodated. A carpenter who does not notice these during measurement will discover them on installation day and either charge extra for the modifications or install something that does not fit cleanly. A thorough measurement visit, with notes and a dimensioned sketch, is a signal of professional practice.
They Demand Full Payment Before Installation
The standard payment structure for carpentry work is 50% deposit when materials are ordered, with the balance due on satisfactory completion and installation. Warning signs: demanding full payment before manufacturing begins; insisting on cash; or requesting the balance before installation is complete and defects have been identified.
The balance payment is your primary leverage for ensuring quality work is completed and defects remedied. A carpenter who collects full payment before you have inspected the installed work has removed this leverage. Pay by EFT — not cash — and retain the balance until installation is done and you are satisfied. Any carpenter who objects to this arrangement is treating their cash flow as more important than your satisfaction.
They Cannot Explain Their Finishing Process
The finish on built-in furniture determines how it looks and how it holds up. Common failure modes: peeling edge tape within months, paint chipping at handles and corners, lacquer crazing in kitchen humidity, or melamine bubbling where it was not properly bonded. All of these are finishing failures — not material failures — and they are entirely preventable with correct technique.
Ask the carpenter how each surface will be finished and what preparation is done before applying paint or lacquer. Proper finishing requires sanding between coats and sometimes a primer coat — not a single application over bare board. Ask what edge banding process they use. A carpenter who cannot explain these choices, or who dismisses the question, is not thinking carefully about finishing quality — and that will be visible in the result.
There Is No Defects Liability Period in the Agreement
Fitted furniture should come with a workmanship warranty — a defined period during which the carpenter will return to fix any defects in fitting, alignment, or finishing that emerge after installation. A reasonable period is six to twelve months. This warranty matters because some defects only appear after the furniture has been used: a drawer that was slightly off-centre during installation becomes a consistent sticking problem after a week of opening and closing.
Ask for the defects liability period to be stated in writing before you sign anything. A carpenter who refuses to commit to a warranty period, or who says "if there are any problems just call me" without a written commitment, is not giving you any real recourse. Without a written warranty, returning for adjustments is entirely at the carpenter's discretion — and their availability and willingness after they have been paid in full may be very different from during the job.
Quick Checklist Before You Sign
- Visited and inspected at least one completed installation in person — not just photos
- Received a written material specification: board type, thickness, hinge brand, runner system
- Confirmed a proper site measurement visit was done — with a dimensioned sketch
- Agreed on a 50% deposit and balance on satisfactory completion — paid by EFT
- Asked for the finishing process explained specifically — sanding, primer, edge banding method
- Confirmed a written defects liability period of at least six months
- Compared at least two quotes — both with material specifications so they are genuinely comparable
- Read reviews from other homeowners about quality after living with the work for several months
Reviews written several months after completion — when edge tape has either held or peeled, when drawers have either stayed smooth or started sticking — are far more informative than reviews written at handover.
