A local window and door company you can actually get hold of
DM Installations is based at Abronhill in Cumbernauld and works right across Central Scotland. Every job is surveyed, ordered and fitted by us — never handed to a subcontractor.
Our Story
DM Installations was started by Martyn after years on the tools fitting windows and doors for other companies. The idea was simple: do the job properly, charge a fair price, and treat every house the way you'd want your own treated.
That's still how it works. You speak to the person who measures your windows, and the same person turns up on fitting day. There's no showroom pressure, no inflated "today only" discount and no salesman on commission.
We fit uPVC and aluminium windows, composite and uPVC doors, French, patio, sliding and bifold doors — and we replace failed, misted double glazing units where the frames are still perfectly good. Replace the pane, not the frame.
