Yes — Fortress repairs and installs all major window types, including casement, sash, tilt & turn, bay, and patio windows. We handle both domestic and commercial glazing, from small residential panes to large shopfront installations.
Absolutely. If your window frame is still in good condition, we can replace only the glass unit — whether it’s single, double, or triple glazing. This is often a quicker and more cost-effective solution than a full window replacement.
We supply and install a wide range of BSI-certified glazing, including toughened safety glass, laminated security glass, acoustic glass, and A-rated energy-efficient double glazing. For commercial settings, we also fit fire-rated, tinted, and self-cleaning glass options.
Yes — all installations meet Part L (energy efficiency) and Part Q (security) of UK Building Regulations, and are fitted by FENSA-registered installers using PAS 24 and BS EN 14351-1 compliant materials.
Yes — whether you have heritage sash windows, modern aluminium frames, or custom shopfront glazing, we can match the size, style, and colour to blend seamlessly with your existing look.
Most residential window replacements are completed within one day, while larger commercial installations may take longer depending on size and complexity. We’ll always provide a clear timescale before work begins.
