Bespoke Windows and Doors for Every Home
Our Windows and Doors are all hand-made in our workshop with precision and attention to fine detail. We are experienced in a wide range of window styles from Floor to Ceiling Box Sashes, Casements, Fixed Panes, Full Bays and Curved Windows.
Our windows can also be crafted from Hardwood, Soft Wood or Accoya and can be finished in any colour of your choice with your choice of ironmongery to match. All windows are fitted using traditional lead weights and security details.


Draft Sealing and Overhaul
Our Expert Team can remove your windows and lovingly update them in our workshop with Draft Sealing, new Sash Cords, new Ironmongery and new Lead Weights. We’ll fit your window back to the original box and ease and adjust the unit to make sure it works like new.

Quality Materials
We use durable, industry-approved materials to guarantee long-lasting results for every project.

Replacement Glazing
We can carefully remove the existing glass in your window and replace it with Double Glazed, Triple Glazed or Vacuum Insulated Glass.
All of our glazing is designed to meet High Energy Efficiency Standards.
