A complete sash window service 

We’ve been selling and installing sash windows for over 25 years now. It’s a sector that requires an in-depth knowledge of both the product − with all of its options, fixings and design detailing − and the types of property it was originally specified for. It’s a specialist business and not the sort of thing you can just drift into. One window might be the same as any other to some window suppliers, but for us the sash requires a specialist team of designers, consultants and installers.

Here's why we're different...

Investment in customer services and training

Cambridge Sash Windows is family owned and run and remains true to its original principles of: quality, service and value. Committed to regularly reviewing procedures in all areas, the company has recently invested in a new estimating system which provides detailed quotations with clear, itemised, cost breakdowns. The latest CAD software and visualisation tools are used to prepare customer presentations by the design team, and all installers benefit from regular, on-going product training.

This attention to detail ensures that the highest standards are maintained across the full range of products and services supplied by the company.


The vast majority of the company's work comes from recommendation, reflecting the care and attention taken with every enquiry. The sales team takes pride in the products and services that they offer and, because Cambridge Sash Windows is an independent installer, enjoy the freedom to research and select product ranges that really match our customer's needs.


All of our window installers are experienced professionals. The majority have been with the company for many years and are used to meeting the high standards demanded by our insurance backed guarantees.

  Generally, we will assign one team to carry out an installation, with the lead installer taking responsibility for the installation from beginning to end. The surveyor, who carried out the home survey, will have discussed the installation plan with the fitting team before their arrival and arranged for any additional building work, if it is included in the quotation.

   And, because of the special requirements of our timber spring and box sash windows, all of our timber installers are tradesmen, and have spent a life-time refining the skills needed to correctly fit a timber box sash window with weights, cords and trim.

Construction and refurbishment

As Paxtons has grown the nature of the work has changed. The company’s move into the design and build of bespoke orangeries and glazed extensions affords its staff a unique insight into the real-world requirements of homeowners, builders and developers. As a result, Cambridge Sash Windows now offers a building repair and refurbishment service for homeowners replacing their sash windows. Expert building teams can restore, replace or adapt masonry, if required, or refurbish the whole bay, or window surround, as part of the sash window replacement scheme. 


To talk to one of our experienced consultants please call our sales office on 01799 520233. They will guide you through the options over the telephone and, if you want us to, arrange a no-obligation visit to your home to properly assess your requirement.

   Having gathered the necessary information and window dimensions, we will then prepare a quotation for the work discussed for your consideration. Again, you are under no obligation and there will be no pressure, promise. That’s not the Cambridge Sash Window way. Ever.

And, all of our installations are covered by DGCOS 10 year guarantees
