Sash Windows Installers in London

Are you looking for sash window installers in London? Look no further than DMI Sash Windows. We are craftsmen with a passion for exceeding our clients' expectations.


Reap the Benefits of Traditional Windows With Modern Glazing

At DMI Sash Windows, we can reproduce exact replicas of your existing windows, but with increased energy efficiency through high specification double glazing and discreet draught proofing. We can do so whilst matching all mouldings and trims to the originals.


Draught proofing also greatly improves the operation of the windows due to the lower friction created when sliding sashes on the draught proof beads. All of our glazing is carried out in accordance with building regulations.


We also specialise in conservation area and listed building projects.


As well as crafting new windows, we can also repair, refurbish and draught proof your existing windows. Please do not hesitate to contact us for more information. No job is too big or too small for our team of sash window installers in London.
