Manage and minimise risks from traditional window defects

Failure to maintain timber windows can lead to severe structural issues, such as spalling on the exterior sub sills and water ingress internally. Early remedial action can prevent these problems from escalating and thus saving the client from significant repair costs at a later stage.

To keep your home looking and performing at its finest, Kensington Sash can restore your traditional windows to their original glory. Carried out in a timely manner without manufacturing lead times. Planning applications are not required for restoration works, perfect for homes that are either listed or those within conservation areas.

Do your sash windows need repairing?

Sash windows are beautiful period features and add great character to a property. We often find that many of them are old, neglected and in dire need of upgrade. If you're questioning sash window repair, please check for the following issues to help determine if it would be a wise to proceed with restoring your windows:

 

  • Draughts and cold spots

  • Rotting timber (important to check sill areas)

  • Windows that are difficult to open and close

  • Damage to/loose fitting locks

  • Broken sash cords 

  • Cracked glass and condensation

It is important to address the issues above as not only can they cause a security and safety risk but a damp, cold and uncomfortable property. We offer expertise in all aspects of timber window restoration.

Common works carried out by our team

 

Timber section repairs

We carefully remove all decaying and rotten timber from the window. Our skilled carpenters then replace these routed out sections with newly spliced in timber matching the original. Small sections are filled smoothly with Timbabuild 2 part system epoxy resin. Once cured the resin can be drilled, stained or painted just like timber. Sometimes we will opt to replace the whole cill with a hardwood replacement designed to match on a like for like basis.

Draught proofing

Generally the basis of all sash window restoration works that we undertake, our draught proofing is a unique and discrete system rebated into the staff bead, parting bead and meeting rail of a sash window. This service can reduce air leakage of up to 50% and includes rebalancing of weights and new sash cords as standard. You will notice a vast improvement in the operation of the window itself as well as the benefits of higher thermal performance from the insulation.

Painting & decorating

Where paint is peeling it is important to redecorate before the exposed timber begins to decay. Our works team use a range of high quality finishes when decorating timber windows, which provide essential protection from the elements and improve the lifespan of your products. Decorating your timber windows and doors adds to the curb appeal and overall appearance of your property and we offer the option of colour matching any Farrow & Ball colour and colours on the RAL chart.

Glazing upgrades

We provide glass replacement services for traditional sash windows and casement windows. We tend to incorporate ultra-slim double glazing units into existing windows, that look just like single glazing to retain the character of the original window whilst still improving the thermal performance and acoustic performance. Suitable for architecturally sensitive buildings and those within conservation areas, our units are guaranteed for 5 years for complete peace of mind. For security, we specify toughened options and 6.8mm laminated glass. Please contact our office for data sheets and technical information available.
