Sash Window Repair in Caterham , Surrey

Decay at the base of your sash windows is a common issue in our local climate, particularly in the exposed sills and lower box frame sections. Rather than suggesting a full replacement, we perform precise timber splicing. By cutting away the compromised, soft timber and introducing high-quality, seasoned hardwood or Accoya, we rebuild the sill to match the original profile exactly. This process effectively seals your window against water ingress and provides a structural base that will last for years, all while keeping your original exterior masonry pointing and interior plasterwork completely undisturbed.

Beyond simple repairs, we help homeowners address the typical draughts and noise issues associated with older properties. We install hidden, high-performance brush seals into the staff and parting beads. This draught-proofing system is machined directly into the timber, allowing us to eliminate cold spots and rattles without altering the slim visual profile of your windows. We also offer expert sash cord replacement using heavy-duty, wax-impregnated cotton cords, alongside the careful rebalancing of your cast iron or lead counterweights to ensure your windows glide smoothly as intended.

Caterham is home to many period properties where maintaining original sightlines is a priority. For standard like-for-like timber repairs and sash restoration, you generally do not require planning consent. However, for homes located within local conservation areas or subject to Article 4 Directions, any alterations—such as upgrading to double glazing—must be handled with care. We have extensive experience navigating these local requirements and can advise you on how to enhance your home's thermal efficiency while satisfying heritage standards.

Our service is built on technical precision and a deep respect for traditional joinery. From broken glass replacement to the installation of A-rated double-glazed units that replicate the look of historic single panes, we are committed to quality. As a FENSA-registered company with comprehensive public liability insurance, we provide a 10-year guarantee on all new bespoke timber window installations. Our goal is to provide a reliable service that gives you peace of mind throughout the entire process, starting with a thorough onsite assessment.
