Expert repair, draught-proofing, and heritage-friendly upgrades for period homes in Leighton Buzzard.
Are these sash window issues affecting your home?
Stiff or rattling sashes, draughty frames, or condensation obscuring your view? These common problems do more than frustrate – they drain warmth, inflate energy bills, and compromise comfort.
Our specialists restore sash windows to their original elegance while integrating modern efficiency, perfect for Victorian, Edwardian, or traditional homes.
Frequent issues we address in Leighton Buzzard:

Rotting timber frames caused by age or moisture

Heat loss through single glazing leaving interiors chilly

Draughty gaps around sashes and meeting rails

Noisy operation from worn cords or loose fittings

Misted glass due to degraded seals
Why choose restoration over replacement?
Preserve your home’s character while enhancing performance with our tailored solutions:

Timber repairs without full replacement
Using Accoya wood splicing or marine-grade epoxy resin, we salvage original frames, retaining their historic charm. This approach avoids the disruption and cost of full replacements, ideal for maintaining period features.
Discreet draught-proofing
Hidden brush seals and silicone weatherstrips eliminate cold draughts, reducing heat loss by up to 20%* while preserving authentic aesthetics.
Heritage-friendly double glazing
Upgrade single-glazed windows with slim vacuum glazing (6.5mm thick, U-value 0.7 W/m²K). This retains the slim profile of traditional sashes while improving insulation and noise reduction.
