Services
Draught Proofing
Our draught proofing service eliminates rattles and heat loss by installing hidden weather seals. We refurbish sashes, replace cords, repair timber, and fit quality fasteners. This service improves energy efficiency while maintaining the window's original appearance, adhering to English Heritage recommendations. Suitable for all sash window conditions, it ensures smoother operation and enhanced comfort.
Double Glazing Services
We integrate double glazed sash units into existing frames, using Fineo Vacuum Glass or N&C Ecolite Slimlite units. This approach retains architectural integrity while improving thermal performance. Our in-house glazing ensures quality control, with U-values as low as 0.7W/(mK) for Fineo units. The process minimizes disruption compared to full window replacements, offering long-term savings and noise reduction.
Sill Replacement
Replacing damaged sills with FSC-certified hardwood, we install damp courses and repair surrounding timber. This service addresses rot caused by weather exposure or gutter issues. Repairs are sealed with Repair Care epoxy resin, primed, and finished to match existing profiles. External render beads are restored for durability, ensuring structural integrity and aesthetic consistency.
Box Repair
Box frame components such as mullions, stiles, and fascia are repaired or replaced using traditional joinery. Repairs include knot treatment, epoxy resin reinforcement, and priming. This service is often conducted alongside sash replacements or draught proofing, ensuring the entire window structure remains robust and functional while preserving historical accuracy for listed properties.
Sash Repair
We repair or fabricate new sash panels using proxy routers and epoxy resin for spot repairs or full replacements. Damaged sections are machined out and filled, with adjustments made to counterbalances for proper operation. New sashes are fitted with 4mm glass and matched to original designs, ensuring seamless integration and longevity while maintaining the window's traditional appearance.
