How Golden Ratio Sash Windows & Doors prioritises your comfort, security, and peace of mind throughout every window installation.
No obligation · Find out how we work in your home.
Investing in new windows is a significant step, but the installation process shouldn't feel like a disruption to your life. At Golden Ratio Sash Windows & Doors, we've refined our workflow to ensure that while we work on your property, your daily routine remains as smooth as possible.
You can find out more about how we manage installations when the home is occupied.
From the first dust sheet laid down to the final quality check, here is our commitment to a professional, hassle-free experience in your home or workplace. While some construction impact is inevitable, our refined workflow always prioritises maintaining your normal daily routine.
We agree on a clear schedule in advance, detailing working hours and daily targets so you're never left in the dark.
Our team treats your space like their own. We provide guidance on preparing your room and use high-grade protective coverings to safeguard your flooring and furniture.
While construction naturally creates some impact, we use modern techniques to keep dust contained and noise to a minimum, maintaining a tidy environment throughout the day.
We typically work on one opening at a time to ensure your property is never unnecessarily exposed. Before we leave each evening, we perform a rigorous security check to ensure everything is weatherproof and locked tight.
Our service includes full waste removal and a final walkthrough with you to ensure every seal, bit of insulation, and finish meets our exacting standards.
For commercial or contractor-managed sites, we also prepare project-specific Risk Assessment & Method Statement (RAMS) documents before work begins.
