We bring your project to life and deliver a great return on your investment. Day-to-day financial and lifestyle benefits can be enjoyed thanks to results that are durable, long-lasting, low-maintenance and energy-saving (e.g. the thermal efficiency of double-glazing upgrades and the elimination of draughts and dampness).

FAQs

In our experience, over 90% of wooden sash windows can be successfully restored. Even where frames look badly weathered or partially rotten, we can replace damaged sections with Accoya® timber, treat surrounding wood, and reinstate the window to better-than-original condition. Replacement is only needed in the rare cases where structural integrity is fully gone — and we'll tell you that honestly at the on-site assessment.
Yes. Our methods are designed to preserve the original character of heritage windows. Our vacuum-sealed double-glazing units are only 6.7mm thick, which keeps structural alterations to a minimum and comfortably satisfies most Listed Building and conservation-area planning criteria. We regularly install draught-proofing and re-glazing in listed properties without compromising original detailing.
Most projects of 10 windows are completed within 1–2 weeks on site, depending on the scope (repair only, full repaint, glazing retrofit, etc.). We schedule the work to suit your timetable and aim to keep disruption minimal. Each window is assessed individually at the start so you have a clear schedule and price upfront.
See our price guide on each location page — for a typical Victorian property, repair & painting starts around £4,650 per 10 windows, with double-glazing retrofit from £9,150 per 10 windows. Final pricing depends on condition and scope; we always provide a free, no-obligation quote after an on-site assessment.
We use Accoya® timber for replacement sections (extremely workable, with extensive durability warranties), Tricoya® veneers for protective panelling on exposed areas, advanced epoxy resin-based fillers, and Fineo vacuum-sealed glass for double-glazing. Together these outperform most traditional materials while keeping the historic appearance intact.
We cover all of Hertfordshire and immediately adjoining areas, including St. Albans, Stevenage, Watford, Hitchin, Hertford, and parts of Bedfordshire, Essex and north London. Get in touch if you're not sure whether you're in our service area.
