Professional Sash Window Replacement Services
When sash windows reach the point where repair is no longer practical, full replacement gives your home a second chance at both performance and period character. Save Our Sash provides specialist sash window replacement across London, working on Victorian, Georgian, and Edwardian properties where original style matters.
Our wooden sash window replacement services preserve everything that makes traditional windows distinctive while resolving the problems that made replacement necessary in the first place.
We manufacture all replacement sash windows in the UK, and every unit is factory-sprayed with micro-porous paint. As registered FENSA members, we ensure that every timber sash window replacement we carry out meets current building regulation requirements. Every project also carries the GGFi 10-year insurance-backed guarantee as standard.
Replacement Sash Windows for Period & Heritage Properties
Period and heritage properties need replacement windows that match their original character, thereby improving thermal comfort. Save Our Sash manufactures bespoke timber sash windows for Victorian, Georgian, and Edwardian homes, precisely matching original proportions, glazing bar profiles, and sash depths.
We regularly work on listed buildings and conservation area properties, producing windows that meet local authority requirements without compromising quality.
We fit replacement sash windows that retain the slim sightlines and authentic movement of traditional timber windows, so the property’s exterior appearance remains intact. Every window is factory-sprayed with micro-porous paint and built to exact site measurements. The finished result looks as though it were always part of the building.
Sash Window Replacement Cost
The sash window replacement cost varies based on a few factors, i.e., the number of windows, their size, and the condition of the existing box frames. Larger windows cost more than smaller, single-glazed ones. Projects covering multiple windows also work out to better value per window than a single replacement, since the time and setup add to the expense.
The cost of replacing wooden sash windows is higher than that of standard casement windows because of the joinery skills and materials involved, but the results last for decades with basic maintenance. Also, replacement sash windows incur a per-unit cost loss on larger projects.
Save Our Sash gives you a full written estimate before starting any work. No hidden extras, no surprises on the final invoice.
Benefits of Replacing Your Sash Windows
Replacing worn sash windows solves problems that repairs cannot. Key benefits include:
- Improved thermal performance: New sashes reduce heat loss through the windows, lowering energy bills year-round.
- Draught elimination: New sashes with correctly fitted draught seals prevent cold-air infiltration that occurs in old, warped windows.
- Reduced outside noise: Bespoke timber replacement windows create a barrier against traffic, neighbours, and general street noise.
- Lower maintenance demands: New timber windows treated with micro-porous paint stay in better condition longer than older, untreated frames.
- Increased property value: Well-fitted, period-appropriate replacement windows improve curb appeal and buyer confidence.
