Regular cleaning and maintenance are essential to keep your skylight dome bright, clear, and weather-tight. This guide will help you protect your investment and maintain the performance of your dome over time.
Why Maintenance Matters
Over time, exposure to weather, UV rays, and debris can:
- Reduce light transmission
- Cause sealant to deteriorate
- Lead to leaks and drafts
A simple maintenance routine extends the life of your dome and keeps your home comfortable.
Routine Cleaning
Frequency:
Clean your dome at least twice a year—ideally in spring and autumn.
How to Clean
- Use a soft cloth or sponge with warm water and mild detergent.
- Rinse thoroughly with clean water.
- Wipe dry with a soft cloth to avoid water spots.
What to Avoid
- Harsh chemicals (e.g., bleach, ammonia)
- Abrasive sponges or scouring pads
- High-pressure water jets
Inspecting for Wear
Every 6–12 months, inspect for:
Cracks or splits
Especially around screw holes or edges.
Sealant deterioration
Look for gaps, peeling, or brittleness.
Loose fastenings
Gently check screws to ensure they are snug.
If you notice any damage, it’s best to arrange a replacement promptly to avoid leaks.
Removing Debris
Leaves, branches, and dirt can accumulate on and around your skylight.
- Use a soft broom or gloved hand to clear debris.
- Do not stand or lean heavily on the dome.
UV Protection
While both acrylic and polycarbonate are UV-stabilised, gradual weathering is natural.
- Polycarbonate offers greater UV resistance.
- Cleaning regularly helps minimise surface discolouration.
When to Replace
If you notice:
- Persistent leaks despite resealing
- Severe yellowing or loss of clarity
- Cracks that compromise the structure
…it’s time to consider a replacement dome.
Illustrative Example
“A homeowner in Nelson noticed leaks after years of neglect. Regular maintenance would have extended the life of their dome by years.”
