Our skilled sash window specialists can repair your rotten wooden window frames and laminate them with Tricoya wood to significantly improve their durability.

Repairing wooden frames is an essential step in sash windows restoration that must be done before or with other services. Our sash windows restoration method allows us to provide an 8-year guarantee on paintwork and 20 years on all repaired sash window parts.

We can also restore sash windows that you may think are not repairable, making our sash window service a great alternative to window replacement.

If you have single-glazed windows, we can install modern, energy-efficient double-glazing units into your existing frames.

We work with windows in Grade 2 listed properties as well as period timber windows in non-listed buildings.

Original sashes functional restoration

• Unblocking stuck or painted shut sash windows
• Broken or snapped cord replacement
• Sash window weights rebalancing
• Pulley replacement
• Restrictors and stops installation

Rotted frames or cracked paint may not affect your immediate comfort as much as a stuck sash or sash that does not stay open or closed due to failure mechanisms. That is why it’s important to restore the functionality of your windows while repairing frames and upgrading glass. Our team of experienced sash window specialists can quickly and easily repair or replace any failed mechanism in your windows.

Sash windows operate on a weight and pulley system that creates a counterbalance with the window, allowing smooth movement between its open and close position. Consequently, any issue with the weight or pulley can make the sash window tricky or even impossible to open. For tasks such as this or any other restoration work that your windows may need, our team will have them fully functioning once again.


We do not operate as an emergency call-out service, but we can repair cords or pulleys as a part of a timber frame restoration or double-glazing installation project.



Sash Window Double Glazing & Draught Proofing

• Improved energy efficiency
• Replace single glazing with double glazing
• Reduce noise in half with new double glazing
• Reduces cold draughts and rattle
• Improve windows security

Original windows can now be retrofitted with slim-profile double-glazed units to improve thermal efficiency and reduce outside noise energy bills. Draught-proofing is an important but often overlooked part of sash window maintenance.

Our sash window specialists can install draught-proofing strips to the meeting rails and staff beads of your windows as well as install or replace existing weather-stripping.

Sash window double glazing is usually done together with sash window draught-proofing for better results.
