Which is cheaper, wooden or aluminium sliding doors?

Wooden sliding doors are slightly cheaper on the lower end (R7,500 vs R8,000), but aluminium is cheaper long-term because it needs no maintenance. A wooden door that needs repainting every 2 years (R500 to R1,500 per paint job) quickly catches up to the aluminium price. For coastal properties, aluminium is the only sensible choice.

Do sliding doors need safety glass?

Yes. In South Africa, SANS 10400 regulations require safety glazing (tempered or laminated glass) in doors, including sliding doors. Tempered glass breaks into small, safe pieces instead of dangerous shards. Always confirm your quote includes safety glass: it's not optional and non-compliant installations can affect your insurance.

How long do sliding doors last?

Aluminium sliding doors with good-quality rollers last 20 to 30 years with minimal maintenance. Wooden sliding doors last 15 to 25 years but need repainting or revarnishing every 2 to 3 years. The most common failure point is the rollers: budget rollers fail in 3 to 5 years. Quality stainless steel or nylon rollers last 10 to 15 years.

Can I install a sliding door myself?

If you're replacing an existing sliding door in the same frame, a DIY installation is possible if you're handy and have someone to help lift the door. For new openings or frame replacements, hire a professional. A misaligned sliding door won't close properly, lets in draughts, and wears out the rollers within months. The R1,500 to R3,500 labour cost is worth it.

Sliding Door Prices in South Africa: 2026 Cost Guide

Sliding doors are the single best upgrade for connecting your indoor living space to a patio, garden, or pool area. In South Africa, standard sliding doors cost R7,500 to R15,000 for wooden and R8,000 to R20,000 for aluminium. Aluminium folding doors (stacker doors) are the premium option at R18,000 to R20,000 per door leaf. Here's what each option costs, how to choose, and what to look out for when getting quotes.

Here's how sliding door prices break down in South Africa for 2026. These are real numbers from SA contractors and suppliers, so you know what to budget when the estate agent says “it just needs a sliding door to the patio.”

Sliding Door Comparison

Door Type	Price Range	Best For
Wooden sliding door (1,800mm)	R7,500 to R15,000	Warm aesthetic, traditional homes, renovations
Aluminium sliding door (standard)	R8,000 to R20,000	Modern homes, coastal areas, low maintenance
Aluminium folding/stacker door	R18,000 to R20,000/leaf	Indoor-outdoor flow, entertainment areas
Double-glazed sliding door	R14,000 to R28,000	Energy efficiency, noise reduction, security
Screen door (sliding mesh)	R1,500 to R4,500	Keep bugs out, ventilation in summer

Wooden vs Aluminium Sliding Doors: Which Wins in SA?

In coastal South Africa (Cape Town, Durban, PE), aluminium is the clear winner. Salt air destroys wooden door frames over time: you'll be repainting and resealing every 2 years. Aluminium doesn't rust, doesn't warp, and needs almost no maintenance. In Gauteng, wooden sliding doors are more common in traditional homes and add a warmer feel, but they still need regular varnishing or painting. Prices are comparable: wooden at R7,500 to R15,000 and aluminium at R8,000 to R20,000. The aluminium folding/stacker option at R18,000 to R20,000 per leaf is the premium choice for creating an open-plan indoor-outdoor lifestyle feel.

What About Folding Doors?

Aluminium folding doors (also called stacker or bi-fold doors) are R18,000 to R20,000 per leaf. A typical 3-leaf opening costs R54,000 to R60,000 before installation. Folding doors are the ultimate indoor-outdoor connection: they completely open a wall to the patio or garden. They're popular in Cape Town where indoor-outdoor living is the whole point of having a house. The downsides: they need more structural support above the opening (a heavy-duty lintel or steel beam), and the hardware (tracks, hinges) needs to be high quality to last. Cheap folding doors start jamming within a year.

Installation: Don't Let This Be Your Hidden Cost

Sliding door installation labour runs R1,500 to R3,500 per door. That's for a straightforward replacement in an existing opening. If you're creating a new opening in an exterior wall, add R3,000 to R8,000 for the structural lintel, brickwork, plastering, and painting. For existing openings, check if the frame is square. SA homes built before 2000 often have unlevel openings that need packing or frame modification, adding R500 to R1,500 to the installation.

Sliding Door Glass Options: What's Worth the Extra Cost?

The glass in your sliding door matters as much as the frame. Single clear toughened glass is standard and included in most quotes. Double-glazed units (two panes with an air gap) cost R6,000 to R15,000 extra per door but cut heat transfer by 40 to 50% and outside noise by 30 to 40%. In Johannesburg where it's hot in summer and cold in winter, double glazing pays for itself in energy savings within 5 to 7 years. Laminated glass (a plastic layer between two glass sheets) adds R3,000 to R8,000 and offers better security: it holds together when shattered. Tinted or reflective glass adds R1,000 to R3,000 and reduces glare and UV damage to furniture. Low-E (low emissivity) glass is the premium option at R5,000 to R12,000 extra: it reflects heat back into the room in winter and keeps it out in summer. For most SA homes, double-glazed with standard toughened glass is the sweet spot.

Hardware Matters: Rollers, Tracks, and Handles

This is where cheap sliding doors fail. Budget rollers (nylon or basic plastic) cost R200 to R400 and start squeaking and jamming within 2 to 3 years. Quality stainless steel ball-bearing rollers cost R800 to R1,500 per set and last 10 to 15 years. The track system is equally important: aluminium tracks with a nylon wear strip cost more upfront but won't corrode or bind. Multi-point locking handles add R1,000 to R2,500 per door but are essential for security: a single-point latch can be jimmied open with a butter knife. If you're in a high-crime area, insist on multi-point locking and a security bar in the bottom track. Ask your contractor what brand of rollers they use. If they say 'standard' or 'generic', pay the R400 to R800 upgrade to quality hardware. It's the difference between a door that glides smoothly for a decade and one that needs replacing in 3 years.

Which Sliding Door Is Right for Your Home?

Coastal home (Cape Town, Durban, PE): Aluminium sliding doors only. Wooden doors will swell, warp, and rot within 5 years. Pay extra for Chromadek or marine-grade finish.
Gauteng home (Johannesburg, Pretoria): Either wooden or aluminium works. Wooden doors add warmth and character to traditional homes. Aluminium suits modern designs. Factor in repainting costs for wood every 2 years.
High-traffic family home: Aluminium with double glazing and quality stainless steel rollers. Stands up to kids, dogs, and daily use for 20+ years.
Entertainment / open-plan: Aluminium folding/stacker doors. R18,000 to R20,000 per leaf but completely opens your home to the garden. Popular in Cape Town, Johannesburg North, and the Winelands.
Rental property or investment: Aluminium sliding doors, lowest maintenance, best durability, no landlord hassles with repainting or warped frames.
Security-conscious: Aluminium doors with multi-point locking (at least 3-point), laminated glass, and a security bar in the bottom track. Add an alarm sensor contact for R300 to R500.

Frequently Asked Questions

Standard sliding doors can be lifted off the bottom track if the top guide rail isn't properly installed. Quality doors have anti-lift devices, a metal bracket or screw in the top track that prevents the door from being lifted up and out. Always check your door has anti-lift protection. For extra security, add a security bar (R300 to R800) that drops into the bottom track, or a pin lock that goes through the frame into the door leaf. Aluminium sliding doors with multi-point locking are significantly more secure than wooden sliding doors with a single latch.

Yes, significantly. Double glazing cuts outside noise by 30 to 40% compared to single glazing. If you live near a main road, highway, or in a noisy suburb, double-glazed sliding doors are worth the R6,000 to R15,000 premium. The air gap between the two glass panes (usually 6 to 12mm) acts as a sound barrier. For maximum noise reduction, ask for laminated glass in the double-glazed unit: the plastic interlayer dampens sound vibrations even further, reducing noise by up to 50%. In Johannesburg near main arterial routes like William Nicol or the N1, this makes a noticeable difference inside the home.
