Roller shutters play a vital role in protecting commercial and industrial properties by offering enhanced security, durability, and operational convenience. Whether installed in shops, warehouses, or factories, a properly fitted roller shutter improves safety, energy efficiency, and long-term performance. However, many businesses face recurring problems due to common installation mistakes that are often overlooked. From incorrect measurements to neglected safety features, even minor errors can lead to costly repairs, reduced lifespan, and serious security risks. Understanding these common roller shutter installation mistakes is essential to ensure smooth operation, maximum protection, and a reliable investment for your business.
Incorrect Measurements at the Start
One of the biggest causes of shutter problems is inaccurate measurement. Even a few millimetres of error can result in shutters that do not fit properly, leave gaps, or fail to operate smoothly.
How to avoid it
- Measure width and height at multiple points
- Account for wall irregularities and material expansion
- For non-standard openings, choose custom-made shutters
Poor Alignment and Levelling
Shutters that are not levelled correctly often appear uneven and may scrape, jam, or wear out prematurely. Misalignment also affects insulation and overall aesthetics.
How to avoid it
- Use a spirit level and square during installation
- Mark fixing points carefully before drilling
- Test shutter movement before final tightening
Over-Tightening Fixings
Fastening shutters too tightly restricts natural expansion and contraction caused by temperature changes. This can lead to warping, cracking, or loosened fixings over time.
How to avoid it
- Leave slight clearance when fixing screws
- Avoid forcing fasteners fully flush against the shutter
- Follow manufacturer spacing and fixing guidelines
Choosing the Wrong Shutter Size or Style
Shutters that are too narrow, too wide, or visually mismatched with the window can disrupt the building’s appearance. Decorative shutters should still look functional.
How to avoid it:
- Ensure shutters appear proportionate when “closed”
- Match shutter design with window type and property style
- Consider how centre rails and panels align with window frames
Using Incorrect Hardware or Fixings
Different wall surfaces—brick, concrete, wood, or cladding—require specific fixings. Using unsuitable hardware reduces stability and lifespan.
How to avoid it
- Select fixings based on wall material
- Use stainless steel hardware in coastal or humid areas
- Ensure hinges, mounts, and tiebacks are correctly positioned
Ignoring Moisture Protection
Improper sealing around fixings can allow water penetration, leading to damp issues and long-term structural damage.
How to avoid it
- Pre-drill holes where required
- Apply sealant around fixings
- Ensure shutters allow proper drainage and airflow
Incorrect Louver Direction
Fixed-louver shutters installed upside-down trap moisture and reduce durability.
How to avoid it:
- Install louvers facing downward
- Check orientation before final mounting
Skipping Surface Preparation and Finishing
For paintable shutters, failing to clean or prime surfaces can cause peeling,
fading, or reduced lifespan.
How to avoid it
- Clean surfaces thoroughly before painting
- Always use primer where required
- Use paints designed for vinyl, aluminium, or composite materials
Neglecting Support and Structural Strength
Large or heavy shutters require additional support. Without it, shutters may sag or pull away from the wall.
How to avoid it:
- Use support blocks at recommended intervals
- Follow load and spacing guidelines
Installation by Inexperienced or Untrained Individuals
Allowing shutters to be installed by someone without proper knowledge or hands-on experience often results in incorrect fitting, poor alignment, and reduced shutter lifespan. Inexperienced installation can also lead to operational issues, safety concerns, and costly repairs or replacements in the future.
How to avoid it:
- Choose installers with proven experience in shutter installation
- Check previous work, reviews, or certifications
