who we are
Specialists in manufacture, replacement and refurbishment of bespoke timber sash windows, casement windows and external doors in South East and East London, in compliance with local building regulations.
We are a small local business with professional, friendly and personal way of working. Although a small team, Sash Window Doctor Ltd. understands the importance of the well run company and has the necessary assurances in place that are as important for us as a business as for our customers.
Based in Dartford, working across South East & East London and North Kent.
We specialise in manufacture and installation of bespoke timer sash and casement windows and doors. Our windows and doors are carefully designed and hand crafted in top grade timber to match the original style. We pride ourselves in delivering products including completion of every installation to catalogue worthy finish.
All of our windows and doors are made to measure in our workshop in Kent.
The extra time and effort is put into the preparation of all our windows and doors, prior to the installation. We preserve all our timber products with timber preservative and they are twice primed and under-coated by hand prior to the installation, using Jotun Demidekk to maximise the pristine finish.
All our new windows and doors are glazed with low-emission argon gas filled sealed units (double-glazed) - internally glazed into solid timber profile - unlike the external putty or beaded glazed windows and doors, that tend to break down over time and damage the units.
We are proud of our products and workmanship and are confident to guarantee all our windows and doors.

what to look out for
There are many window / door companies out there to choose from, however increasingly so, it can get a bit overwhelming for the homeowners to choose the right contractor, when bespoke style needs to be preserved, especially when budget is stretched. Here are some important points to look out for / take into consideration when choosing the right team to do the job:
Make sure your window / door replacements will be guaranteed and certified (CERTASS or FENSA) as well as insurance back guaranteed!
Will the windows be made according to building regulations / conservation / like for like in style.
Do speak to previous customers and do see the completed installations where possible. It is not same as seeing windows sitting in the workshop or shop shelf as is on the completed installation!
Do check quality of the timber, design and preparation process it goes through prior to the installation - especially if important to replicate the original slim profile style - very important in conservation areas!
Beware of the imported windows and doors, made out of proportions, not matching the original style of traditional windows and doors.
When taking the cost into consideration, do think long term, as immediate saving may cost more further down the line. Choosing the cheapest may not always work out 'cheaper' in the long run
We only use top grade timber (Grade A) - Swedish Redwood Pine, Meranti Hardwood or Accoya. All our timberwork is preserved with timber preservative and is twice primed and undercoated prior to the installation.
