And just as importantly:
“Should I install a sliding door myself, or use a professional?”

This in-depth guide walks through the installation process, compares DIY kits (such as Bunnings sliding doors) with custom aluminium sliding doors from EZ Windows, and helps you decide the safest, most cost-effective approach.
