My main focus of work comes in the form of renovation services. I take your windows that are showing signs of damage and inefficiency and turn them into high quality performing sash windows that look brand new. By using a perimeter sealing system, the windows can be taken out and repaired from the inside. This is much faster and means you don’t have to spend time climbing up ladders on the outside of buildings in order to reach difficult windows.

This is what I recommend anyone with older windows to have installed as non of the appearance features are affected but it can prevent draughts and dust getting in and causing problems, like rattling of the window and damp in rainy weather. With a perimeter sealing system the sashes can be taken out in minutes and renovated to a level that you are certain to be satisfied with.

A common way that windows are damaged is broken glass. At David Humble I use new or when possible recycled glass to do all I can for the environment and offer the nearest style we can to the original. As I said the process is very simple and involves removing the beads around the sashes then the sashes themselves. Next they have to be deglazed and repairs carried out including any paint being removed.

Pulleys are often common places where windows break so I carry out services and replacements to ensure they last as long as possible. All appropriate adjustments and balancing is completed to create a perfect fit and all the beading, lifts and catches are added to complete the window renovation and draft proofing. If you feel you need more information to make your decision I am always available to talk to by calling 01670 515 622 or if you prefer emailing me at

Sash windows, especially in old Georgian and Victorian homes can become damaged over time due to inclement British weather and the environment in general. If this was to happen thankfully there is a small firm who can help to restore your sash windows to their original quality.


Many of the sash windows that exist today are over 100 years old and due to the elements many are not in the greatest of conditions. Instead of replacing authentic sash windows with more modern uPVC it is cheaper and much more environmentally friendly to repair your existing windows.


My renovation services offer sympathetic restoration to ensure your sash windows are at their best. I undertake a full clean and maintenance as well as adding draughts and insulation.
