Our repair process is detailed and precise ensuring that each sash window is restored to its best possible condition. Here’s how we do it:
Initial Free Survey and Assessment: We begin with a thorough inspection of each sash window to identify areas of damage or deterioration. This includes checking for rot, warping, broken glass, and malfunctioning components.
Careful Removal and Dismantling: We carefully remove the sashes from the frame, allowing us to work on each component without risking further damage to the window or surrounding structure.
Repair and Restoration: Using traditional joinery techniques, we repair or replace any damaged timber, reglaze broken panes, and replace or refurbish any worn or broken hardware, such as sash cords, weights, and pulleys.
Frame and Sill Repairs: We repair any damage to the window frame or sill, ensuring that they are structurally sound and free from any rot or decay. This may involve using specialist wood repair systems or replacing sections of timber with matching materials.
Reassembly and Rebalancing: Once all repairs are completed, we reassemble the window, ensuring that the sashes are rebalanced and aligned correctly. We test for smooth operation and adjust as necessary to ensure the window opens and closes easily without rattling or sticking.
Final Checks and Testing: Finally, we finish the repaired window with suitable paints or stains to protect the timber and match the appearance of the existing windows. We can also apply specialist coatings for additional weather resistance and durability if requested.
We are committed to using only the highest quality materials to ensure our repairs are long lasting and sympathetic to the original design of your sash windows. These materials include:
Sustainably Sourced Timber: Where possible we use sustainably sourced, high quality timber that matches the original wood in terms of grain, texture, and durability.
Specialist Wood Repair Systems: For minor rot or damage, we use specialist resin systems that bond with the timber to restore its strength and stability.
Heritage Glass and Glazing Options: We offer a range of glazing options, including traditional single glazing, toughened safety glass, and energy efficient double glazing, depending on your needs and preferences.
High Quality Hardware: We replace any broken or worn components, such as sash cords, weights, and pulleys, with high quality, durable alternatives that match the original fittings.

Yes. Many rotten timber windows can be repaired without replacing the entire window. Damaged areas can often be removed and rebuilt using new timber sections, specialist resin repair systems or a combination of both methods.
The suitability of a repair depends on the extent and location of the damage. Localised rot, failed joints, damaged sills and deteriorated lower frame sections can often be repaired. Complete replacement may be more appropriate where the window is extensively rotten, structurally unstable or has already undergone several unsuccessful repairs.
We repair a wide range of traditional and modern timber windows, including sash windows, casement windows, fixed windows, bay windows, bow windows, cottage-style windows, fanlights and shaped or curved windows.
We can repair or replace window sills, sash rails, casement rails, glazing bars, stiles, mullions, transoms, frame sections, sash boxes, pulley stiles and other damaged timber components. The repair method will depend on the construction and condition of the window.
Yes. Rotten timber window sills can often be repaired by removing the decayed timber and fitting a new timber section. Where the damage is more extensive, the complete sill or sill front may need to be replaced.
Yes. The lower sections of timber window frames are particularly vulnerable to moisture and decay. Damaged areas can often be cut back to sound timber and rebuilt using durable replacement timber and specialist repair products.
Yes. Where the surrounding window remains in good condition, individual components can often be repaired or replaced. This may include a sill, rail, glazing bar, sash, casement or section of the main frame.
A timber splice repair involves cutting out the rotten or damaged section and joining a new piece of timber to the remaining sound material. The new section is shaped to match the original profile and securely joined to the existing window.
A resin repair uses a specialist two-part repair system to rebuild smaller areas of damaged or rotten timber. The decayed material is removed, the remaining timber is treated and the repair area is reconstructed using a durable epoxy resin designed for external joinery.
No. Resin is most suitable for localised areas of decay where enough sound timber remains. Larger or structural areas of damage may require a timber splice, a replacement component or a complete replacement sash or frame.
A properly completed repair can provide a long-lasting result when the source of the moisture is addressed and the window is correctly maintained. The lifespan will depend on the repair method, timber condition, exposure, paint system and future maintenance.
We commonly use durable hardwoods such as Sapele and modified timbers such as Accoya. The most appropriate timber will depend on the window design, the type of repair and the existing material.
Yes. New timber sections can be shaped to closely match the original mouldings, rebates, glazing bars and other details. Where possible, the existing component will be used as a template to create an accurate replacement.
Yes. We can replicate many traditional window features, including moulded glazing bars, sash horns, shaped rails, decorative mouldings and unusual frame profiles. Bespoke components can be manufactured in our workshop where necessary.
Yes. Timber window repairs are often suitable for properties in conservation areas because they help retain the original appearance of the building. Where replacement components are required, they can usually be made to closely match the existing design.
Yes. Loose glass may be caused by failed putty, damaged glazing beads or movement within the sash or casement. We can secure or reglaze the glass and repair any surrounding timber damage where necessary.
Yes. Where a sash or casement is beyond economical repair, we can manufacture a bespoke replacement to fit the existing frame. The new component can replicate the original design while incorporating improved glass, draught proofing or hardware where appropriate.
We inspect all accessible areas during the survey. However, some deterioration may remain concealed beneath paint, behind glazing, within joints or underneath existing repairs. Further damage may become visible once work begins and affected areas are opened.
If significant additional damage is discovered, we will explain the problem and recommend the most suitable repair. Any substantial extra work or cost will be discussed before proceeding.
Many repairs can be completed internally, although external access may still be required to operate the window, remove sashes or casements and inspect the full extent of the damage. Access requirements will be discussed before the work begins.
Repairing a window is often more economical where the damage is limited and the majority of the original window remains sound. However, extensive repairs can sometimes approach the cost of replacement. We will advise which option provides the best long-term value.
