Our comprehensive range of services is committed to preserving traditional sash windows while improving their energy efficiency to compete with modern A-rated windows.
Our window specialists are experienced in handling all types of timber frame issues. Over the past ten years, we have restored thousands of sash windows. We understand how to enhance the durability of restored frames, making them as long-lasting as those made with Accoya wood.

To achieve this, we have developed our unique timber laminating technique, which imparts exceptional durability to the original sash windows undergoing restoration.

Sash window draught-proofing is a great option for Grade 2 listed buildings to remove rattling and draught. It does not require planning permission. We usually do window draught-proofing with timber frame repairs or double glazing retrofit.
Our team instals new staff and parting beads with draught-proofing seals and adds weather seals to the meeting rail. We can also draught-proof casement windows and french doors.Â

Living in a period home with single-glazed windows, you’re well aware of the challenges during winter, as well as the effort and cost required to heat your home. Moreover, if you’re situated near busy roads, you know how easily sound penetrates your home through a single pane of glass.Â
Â
We have encountered numerous properties facing this issue and have successfully helped many homeowners achieve what once seemed impossible: installing double glazing with all its associated benefits while retaining the original timber frames.
Â
All of this has become possible due to the innovative vacuum double glazing, which is only 7mm thick. Its slim design makes it an ideal fit for the narrow stiles and glazing bars of period sash windows. This new generation of glass delivers superior thermal performance and U-value compared to double Low-E and 34mm triple glazing.

Areas Of Service
Our team of sash window specialists can replace inefficient single-glazing in the original box sash window with heritage double-glazing. This will improve the energy efficiency of your traditional timber sash windows and reduce energy bills.
The thermal photo below shows double-glazed sash windows by our team.
The ground floor window of the period property is single-glazed, while the window above it has been retrofitted with slim-profile double-glazing. You can clearly see the significant thermal difference between the two.
Traditional wooden sash windows can now be double-glazed, so you do not need a more expensive window replacement service.
The innovative vacuum double glazing is eight times more efficient than single glazing and four times more efficient than secondary glazing. This advanced glass technology also boasts greater durability than standard double glazing insulated with inert gases like Krypton and Argon.
U-value of different glazing solutionsÂ
The U-value measures heat loss; it tells you how energy-efficient glazing is. The lower the U-value, the better thermal insulation glazing has.
Unlike other sash window companies, our primary focus is window refurbishment and retrofitting; we don’t sell new windows or double-glazed sash inserts. Our expert team is dedicated to the concept of repair rather than replacement.
We also don’t promote draught-proofing as a miracle solution for all energy efficiency issues, as some companies do.
Our approach is direct and honest; we will only recommend a service that effectively addresses your problem. The staff members who attend our quote meetings are genuine window experts, not salespeople.
For your peace of mind, our services come with guarantees from our company and manufacturers of products we use, such as vacuum double glazing, timber, and seals.
We offer an eight-year paintwork guarantee and 20 years on repaired timber window parts. The vacuum double glazing we use has 15 years manufacturer warranty covering failed double-glazed units.
We pride ourselves on delivering a high-quality job that our customers will be delighted with. Don’t just take our word for it, have a look at what our clients and customers have said about our services.
