Frequently Asked Questions
What sash window brand do you install?
We install Victorian Sliders ECOSlide — the UK's leading sliding sash window brand. Victorian Sliders extrude their own PVC-U profile in South Wales exclusively for ECOSlide. They feature welded corners, slim midrails, deep bottom rails, and run-through sash horns for authentic period appearance. Every installation is FENSA registered with a CPA insurance-backed guarantee.
Can sash windows be used in conservation areas?
Often, though it depends on your local planning authority. Victorian Sliders ECOSlide is designed to replicate timber originals with slim sections, run-through horns and a deep bottom rail. Some councils name specific corner-joint requirements, so check your authority's published window guidance before ordering.
How much do sliding sash windows cost?
Final price depends on size, configuration (sash size, Georgian-bar option, deep bottom rail) and the colour or woodgrain finish. Every installation is FENSA registered with a 10-year CPA insurance-backed guarantee. Request a free no-obligation quote.
Do they tilt for cleaning?
Yes — both sashes tilt inward for easy cleaning from inside the property, removing the ladder access required by traditional timber sash windows.
What guarantees do you offer?
Victorian Sliders, who manufacture these sliding sash windows at their own extrusion plant in South Wales, provide a manufacturer warranty on profiles, sash mechanisms and hardware. Each installation is FENSA registered for Building Regulations compliance and supported by a 10-year CPA insurance-backed guarantee on the fitting.
