We specialise in sash windows restoration, repair, draught proofing, and double glazed replacement throughout London and Kent. We believe in restoration over replacement and will always help you to maintain your original windows if at all cost effective. When customers wish to re-use their original windows we are able to help almost every single time and pride ourselves on saving quality joinery from cluttered landfill sites or incineration. Our normal policy is that the carpenter you meet on the day of survey will carry out the work at your property.

We carry out repairs to sash windows everyday and always keep costs to a minimum. We are always pleased to salvage what you have and will work with your existing windows if at all possible. We can repair almost any window and pictured below is a typical example well within economic repair.

Should you accept the quote you receive, booking is very simple and straight forward. Call our office to arrange the nearest available time, or if you prefer a date further back to suit yourself. You will then have dates pencilled in which will be confirmed on receipt of your deposit.Our normal working hours are from 08:00-14/16:00 and office hours 09:00-17:00 Monday to Friday.

On occasions you may require your windows to be decorated at the point of overhaul and draught proofing. We can cater for this by providing an integrated quote and service between the two. We work closely with decorators who specialise in the decoration of sash windows. On the other hand we are also happy to help talk you through every stage of decorating your own sash windows. There is always a certain amount of satisfaction from taking on this type of work!

We are often asked if we can help with casement windows and doors. We can manufacture any joinery and are happy to assist with this type of work. We regulary service, repair and draught proof casement windows and doors. To service casements we remove them. Replace hinges if required. We then rebate the same groove to draught proof all four sides of the casement. Once draught seals are attached and casement is closed we have created a complete perimeter seal.
