Services
Sash window restoration
Specialised restoration of period sash windows preserves historical features while improving functionality. Our process includes joint reinforcement, rot-resistant timber lamination, and vacuum glazing installation. This service enhances structural integrity and thermal efficiency without altering original aesthetics, ideal for Grade 2 listed properties and heritage buildings.
Double glazing retrofit
Retrofitting existing timber windows with slim-profile double-glazed units improves energy efficiency by up to 12 times. We maintain original frames while installing 7.7mm vacuum glazing, achieving 0.7 U-Value performance. This solution reduces heat loss, noise pollution, and UV damage to interiors without compromising architectural authenticity.
Draught-proofing
Precision draught-proofing systems eliminate gaps between sash components and frames. Our brush-seal technology reduces heat loss by 25%, minimises rattling, and improves acoustic insulation. This service extends window lifespan by preventing moisture ingress and maintaining consistent indoor temperatures.
Rotten wood replacement
Targeted replacement of decayed window components using Accoya and Tricoya wood. We employ splice repairs for partial damage or full section replacements for severe rot. This process restores structural integrity while maintaining original window profiles, backed by long-term durability guarantees.
Heritage window upgrades
Tailored upgrades for listed buildings and conservation areas maintain historical accuracy while meeting modern standards. Services include glazing bar preservation, traditional paint restoration, and sympathetic double-glazing solutions. Our approach ensures compliance with heritage regulations while enhancing thermal performance and security.
