Most window faults are repairs, not replacements
A misted pane, a dropped sash, a handle that spins, a door that will not lock — all fixable in a single visit, usually for a fraction of a new window. If it is an emergency we make it safe first and glaze it properly after.
The economics of this trade push hard towards replacement, because a new window is worth far more than a repair and salespeople are usually paid on the value of the sale. So a misted pane gets quoted as a new window and a stiff handle gets quoted as a new door.
The sealed unit and the frame are separate components. So are the hinges, the handle and the lock. Any one of them can be replaced while the rest of the window carries on for another twenty years — and none of it is notifiable work, because replacing a part in an existing frame is a repair.

When replacement is genuinely the answer
We will say so rather than repairing something that is finished. Replace when the frame itself has failed — corner welds split, timber rotted past its joints, or pre-1990s aluminium with no thermal break streaming with condensation every winter. Replace when you are spending a meaningful fraction of a new window on a frame that will need the next repair shortly.
Repair everything else. And if it is a replacement, supply only takes about a week rather than the 8–12 weeks that is normal in this trade.
Repairs — common questions
Is it cheaper to repair or replace a window?
Repair, in nearly every case where the frame is structurally sound. A misted sealed unit is £80–£190 against several hundred pounds for a whole new window, and the frame is a separate component that usually has years left in it.
Do window repairs need building regulations approval?
No. Replacing glass or hardware in an existing frame is a repair and is not notifiable. Replacing the whole window is, and that is where a Competent Person Scheme registration matters.
Why do companies quote a new window for a small fault?
Because replacement is worth far more than repair, and salespeople are usually paid on the value of the sale. A misted unit says nothing about the condition of the frame.
How fast can you attend an emergency?
It depends on your postcode and what is already booked, which is why we ask before quoting a time. Making a property safe and glazing it properly are separate visits.
Can I buy the parts and fit them myself?
Yes. Handles, hinges, cylinders and sealed units are all available supply only, and some of them are genuinely easy jobs. Send a photo and we will identify the right part.
Do you repair windows you did not supply?
Yes. Most hardware is more standardised than it looks, and we can usually identify a system from photographs of the mechanism, the handle and the cylinder.
