Replacing tired sash windows with handcrafted replicas 

If our draught-proof overhaul service doesn’t meet all your needs, the next step is to replace your existing sash windows with new bespoke wooden sliding sashes—available in single or double-glazed versions. We retain your original box frames wherever possible, meaning you keep the classic look of your home with all the benefits of improved comfort and efficiency. 
 
These new sashes will greatly increase your home's heat efficiency, reduce outside noise, and eliminate condensation—without compromising the original appearance or charm of your period property. 

Built by hand with care and precision 

Your wooden sliding sashes are: 
Crafted in our joinery 
Spray-painted in our own spray booth 
Glazed and finished by us—David, Damien, and Lulu—in our Windsor-based workshop 
Every sizing, shape, and moulding is recreated to match the original specifications of your existing sashes. The end result is an exact bespoke replica of the beautiful wooden box sash windows originally crafted by expert joiners over a century ago. 

Why we use Accoya® wood 

We make all of our bespoke sashes using Accoya®, the perfect durable, sustainable timber for window and door construction. Accoya is made from fast-growing Radiata Pine, a responsibly sourced material. It undergoes a process called acetylation, which gives the timber its exceptional strength, stability, and resistance to rot. 
 
This process is completely non-toxic, and the resulting wood comes with a 50-year guarantee. 

Seven-coat paint finish 

Your new sashes receive seven coats of paint, using a waterborne acrylic polyurethane that conforms to BS EN 335-1. This ensures: 
 
A long-lasting, durable finish 
Excellent weather resistance 
Superior protection for years to come 
 
We can colour match your existing windows or help you choose a fresh new shade. 

Glazing built to modern standards 

All our double-glazed units are toughened as standard, conforming to BS EN 12150. This means: 
Improved thermal efficiency 
Increased safety and strength 
Glass that is approximately five times stronger than ordinary annealed glass 
We can also provide a range of patterned and decorative finishes, depending on your needs.
