If your double glazing has misted over, stopped closing properly or the handle has gone, you almost certainly do not need new windows. You need somebody to repair the double glazing you already have.
That is the whole of what we do. We are two people, family run, more than thirty years of it in North Lanarkshire, and we carry out double glazing repairs across Wishaw and the surrounding towns rather than sell you replacements you do not need.
What double glazing repairs usually turn out to be
Almost every call we get comes down to one of a handful of things, and none of them require a new window.
A misted or blown unit. The two panes of glass in a double glazed window are sealed together with a gap between them. When that seal fails, moisture gets into the gap and you get fog, condensation or streaks that you cannot wipe off because they are inside the glass. The frame is usually perfectly fine. The sealed unit comes out and a new one goes in, which is a glass unit replacement.
A window that will not close or lock. Usually a hinge that has dropped, a worn gearbox or a locking mechanism that has stopped engaging. The window itself is sound.
A handle that spins, snaps or sticks. One of the most common calls and one of the smallest jobs.
Hinges that have worn or seized. A window that catches on the frame, drops at one corner or takes a shove to shut has generally gone on its hinges.
Draughts, rattles and whistling. Nearly always the rubber gaskets and seals around the opener rather than anything structural, and one of the cheapest things on the list.
Cracked or broken glass. Made to measure, and again the frame stays exactly where it is.
Can blown double glazing be resealed?
This is asked a lot, so here is the straight answer: no, not in any way that lasts.
A sealed unit is exactly that, a factory sealed assembly with a desiccant strip inside the spacer bar that absorbs the small amount of moisture present when it is made. Once that desiccant is saturated and the perimeter seal has failed, the unit has reached the end of its working life. There are people who will drill the glass, blow it out and fit a vent, and it will look clearer for a while, but you have then got a deliberately ventilated unit that is no longer a sealed one, and the misting usually comes back.
Replacing the unit is the honest fix, and because the frame, the hinges and the handles all stay where they are, it is a fraction of the cost of a new window. There is more on this in our guide to why double glazing mists up.
Does the whole window need replaced?
Very rarely, and we will tell you plainly when it does.
The frame, the glass and the hardware are separate things. A failed unit does not mean a failed frame. Worn hinges do not mean a failed window. In the large majority of the double glazing we look at, one component has reached the end of its life and everything else has years left in it.
The cases where replacement genuinely is the answer are frames that have distorted or gone brittle with age, and windows old enough that nearly every part on them is failing at once. That is a small minority. If yours is one of them we will say so, and we also fit new and replacement windows, so you are not being sent elsewhere. Our article on whether to repair or replace goes through it properly.
Most of the people who call us have already had somebody out who told them the whole window needed done. A large part of our work is proving that it does not.
What double glazing repairs cost
There is one figure we can give you up front, and we would rather be honest about the rest than publish a list that falls apart the moment we see the job.
Replacing a failed sealed unit in an existing uPVC frame starts from £75. That is a starting figure and it is for a small pane, the sort of hopper vent that sits above or below a main window. A larger pane, toughened glass, obscure glass for a bathroom, Low E energy glass, a shaped or leaded unit will all cost more, and how much more depends on the window in front of us.
Everything else is quoted on its own. Two jobs that sound identical on the phone can need completely different parts. “My window will not lock” might be ten minutes of adjustment or it might be a full mechanism. Glass is made to measure every single time. Publishing one number for that would mean either overcharging you on the easy version or undercutting ourselves on the hard one.
There is no call out fee. You do not pay us to turn up, you do not pay us to look and you do not pay for the quote. If you decide not to go ahead, you owe us nothing. You pay for the work done and nothing else.
There is a fuller explanation of what moves a price on our window repair prices page, and a worked example in what it costs to fix a misted window.
How to get a real number quickly
Send us a photo. It is by a distance the fastest route to an actual figure.
A picture of the window on WhatsApp, a rough idea of how big the pane is and a line about what it is doing is usually enough for us to come back with a real price the same day. Most misted unit jobs and most handle and hinge jobs can be priced from a photo without anybody coming out at all.
If you would rather talk it through, ring us. If it is easier to type it, use the contact form. All three land with the same two people, and we are open eight until five, Monday to Friday.

Common questions
Is misted double glazing worth repairing?
Yes, in nearly every case. The fault is in the glass unit, not the window, so replacing the unit restores the window for a fraction of the cost of a new one.
How long does a sealed unit replacement take?
Most single units are done in well under an hour once the glass is with us. The glass itself is made to measure, so there is normally a short wait between measuring and fitting.
Do you repair double glazing on wooden or aluminium frames?
We work mainly on uPVC. Ring us with what you have got and we will tell you honestly whether it is one for us.
Will a new unit look different from the rest of the house?
It should not. We match the glass specification to what is coming out, including obscure patterns and energy coatings where they are there.
Do you guarantee the work?
Yes. Ask us what applies to your particular job when we quote it.
Do you take card?
Yes, along with cash and bank transfer.
Ready when you are
If you are in Wishaw itself, there is a page covering windows and doors in Wishaw that puts the repairs alongside the styles we fit.
Send a photo on WhatsApp, call us on 01698 604 278, or fill in the contact form and we will come back with a real price rather than a range. If it turns out to be a window repair of another kind, that is the same two people and the same no call out fee.
