As an expert in the South African blinds industry, I have seen countless installations across the country, from modern apartments to the sun-drenched homes requiring roller blinds in Cape Town.
This guide provides you with the exact process we use for a flawless finish every time. I will walk you through the entire process, from measuring your windows to fitting the final safety clip, so you can decide whether to tackle the job yourself or call an expert.
Before You Begin: Essential Preparation
Getting the preparation right is more than half of the battle. Rushing this stage is the single biggest cause of installation problems. Before you even pick up a drill, you need two things: the right tools and exact measurements.
Tools and Materials You Will Need
Gathering everything beforehand prevents interruptions and mistakes. You do not need a complicated workshop, just a few key items:
- A high-quality steel tape measure
- A pencil for marking
- A spirit level
- A drill (cordless is most convenient)
- Correct drill bits for your wall (e.g., masonry bit for brick, standard bit for wood)
- A screwdriver or screwdriver bit
- The blind kit (blind, brackets, and screws)
How to Measure Your Windows with Precision
This is the most important step. An error of just a few millimetres can ruin the look and function of your blind. There are two ways to mount a roller blind:
1. Inside Mount (Recess Fit)
Provides a neat, integrated look where the blind sits inside the window frame.
- Measure the Width: Take three measurements (top, middle, bottom). Use the smallest width.
- Measure the Drop: Take three height measurements (left, centre, right). Use the smallest height.
- Check for Obstructions: Ensure the blind won’t hit handles or window stays.
2. Outside Mount (Face Fit)
Used when the recess is too shallow or you want to block more light.
- Measure the Width: Measure the recess and add at least 50mm to each side (100mm total) for light coverage.
- Measure the Drop: Measure the recess height and add at least 70mm to the top for secure bracket fixing.
The Step-by-Step DIY Installation Guide
Before you pick up the drill, take a moment to unbox your blind and lay everything out on a clean surface. It is essential to identify the control-end (the side with the chain) and the pin-end (the side with the plunger) so you can decide which side of the window you want the chain to hang on. Most South Africans prefer the chain on the side easiest to reach, away from furniture or tight corners. Once you’ve confirmed the orientation, you’re ready to start marking your heights.
Step 1: Mark the Bracket Positions
Whether fitting inside or outside the recess, the brackets must be perfectly leveled.
- Inside mount: Hold a bracket about 50mm from the side and mark the screw holes.
- Outside mount: Position the bracket at your desired height (at least 50mm wider than the recess) and mark.
Step 2: Fix the First Bracket
Drill pilot holes on your marks. If you are drilling into South African brick or plaster, insert a wall plug (Fischer plug) first. Screw the first bracket securely into place.
Step 3: Fix the Second Bracket
Hold the second bracket at the opposite end. Use your spirit level across the top of both brackets to ensure they are perfectly aligned. A blind that isn’t level will drift to one side and fray. Once level, mark, drill, and fix.
Step 4: Install the Blind
Now that your brackets are securely mounted, it’s time to fit the blind into place, starting with the end that allows for the most flexibility.
- Insert the pin-end (the spring-loaded end) into its bracket first.
- Push the blind toward the pin-end to compress the spring.
- Align the control-end (with the chain) with the slots on its bracket and lower it until it clicks.
- Test the operation by pulling the chain; it should move smoothly and straight.
Step 5: Attach the Child Safety Device
Securing the safety device is a non-negotiable step to protect children and pets from cord hazards. With the blind fully lowered, mark the position for the cleat or tensioner so the chain remains taut but not stretched, then screw the device firmly into the wall.
Common DIY Mistakes to Avoid
To ensure your window treatment looks professional and functions flawlessly, keep these frequent pitfalls in mind as you work through the installation process.
- Inaccurate Measurements: Always follow the “measure three times, use the smallest” rule for recess fits.
- Brackets Aren’t Level: Even a slight tilt will cause the fabric to telescope and ruin the edges.
- Using the Wrong Fixings: Standard screws won’t hold in a plastered brick wall. Always use the appropriate wall plugs.

FAQs
How long does it take to install a roller blind?
A pro takes about 20–30 minutes. For a first-timer, set aside at least an hour to ensure your leveling and measuring are spot on.
Which is better: inside or outside mount?
Inside mounts look cleaner and more modern. Outside mounts are better for total light blockage (blackout) or if your window handles stick out too far.
Can I install a roller blind on any type of wall?
Yes; plaster, brick, wood, or steel. The secret is simply using the right drill bit and the correct wall plug for the material.
How do I clean my roller blinds?
Dust regularly with a soft brush attachment on a vacuum. For stains, a damp cloth with mild soap works best—never soak the fabric or use harsh chemicals.

Costs vary based on location and the number of blinds. At Jacobs Blinds, we provide a clear, upfront quote covering both the product and the expert installation.
