Is your window jammed shut or are the hinges wearing? Are your handles wobbly or damaged? We can replace or repair most parts of any uPVC or double glazed window.

    Common window problems we fix

    Most double glazing faults are down to worn hardware or seals, not the window itself. Repairing rather than replacing is quicker, far cheaper, and usually all your windows actually need.

    Based in Wishaw, we cover Wishaw, Motherwell, Hamilton and across Lanarkshire. For a quick, honest quote call 01698 604 278, message us on WhatsApp, or use our contact form. A photo of the problem is often all we need. And with over 30 years’ experience and a no-fuss guarantee on every job, you’re in safe hands: see our 100+ five-star reviews.

    How we approach window repairs

    Tell us what your window is doing, whether that is sticking, draughty, misted or not locking, and we’ll come prepared. Worn friction hinges, loose handles, failed gaskets and faulty locks are everyday fixes for us and are almost always sorted on the spot. If a sealed glass unit has misted, we can replace just the glass and keep your existing frame (see our glass unit replacement service). Wherever we can, we’ll get your window working again in one visit.

    The real cost of repair versus replacement

    Replacement-window salespeople will tell you a faulty window means a whole new window. It rarely does. A draughty or stiff window is usually a £-not-£££ fix, a new hinge, a handle or a gasket, and repairing it keeps the frame you already have out of landfill. We’ll give you an honest assessment every time, and only ever recommend replacement when a repair truly isn’t worthwhile.

    When replacement genuinely is the answer, we fit those as well. Our new and replacement windows page covers the styles we supply, from casement and tilt and turn to flush sash, what actually drives the price, and how we quote.

    Signs it’s time to have your windows looked at

    It’s easy to put up with a window that’s not quite right, but small faults tend to get worse (and more expensive) if they’re left. It’s worth giving us a call if you notice any of these:

    • The window is stiff, hard to open, or won’t stay open
    • You can feel a draught around the frame, or your room is colder than it should be
    • The handle is loose, stiff, or spins without engaging the lock
    • There’s condensation or misting between the panes of glass
    • The window doesn’t lock properly, a security risk worth sorting quickly

    Catch these early and the fix is usually quick and inexpensive. Leave them, and a simple hinge or gasket problem can turn into water damage or a seized mechanism.

    What a window repair costs

    Every job is priced on what it actually needs, so we do not publish a fixed list. As a rough guide, a replacement sealed unit for a misted window starts at £75, and a handle, hinge or gasket is usually the smallest job on the van. The only figure that matters is the one for your window, and you get that before any work starts. There is no call out charge and nothing to pay for looking. Our window and door repair prices page explains what moves a price up or down.

    If more than one window has gone at the same time, say so when you phone. Three units done on one visit costs less per window than three separate visits, and it saves you taking three mornings off work.

    What we carry in the van

    Most repairs are finished on the spot because the common parts travel with us: espagnolette locks and gearboxes, euro cylinders, friction stays and hinges, handles in white, chrome and gold, keeps, packers, gaskets and beading. Glass is the exception. Sealed units are made to measure, so we take the sizes on the first visit and come back to fit once they are ready, normally within a few working days.

    If a part has been discontinued, which happens on windows fitted in the eighties and nineties, we will tell you straight and look for a modern equivalent that fits the same fixing holes rather than pushing you towards a whole new frame.

    Why a window stops working properly

    It helps to know what is inside a uPVC window, because it explains why nearly all of this is a repair rather than a replacement.

    An opening casement hangs on a pair of friction stays, the flat metal arms you see when the window is open. Those arms carry the whole weight of the sash and control how far it swings. Running round the edge of the sash there is a locking mechanism, usually a strip with mushroom shaped cams on it, driven by the handle. Turn the handle and those cams rotate into keeps fixed in the frame, pulling the sash tight against the gasket.

    So there are three things that have to stay in agreement: the stays holding the sash in the right place, the cams lining up with the keeps, and the gasket being soft enough to compress. When a window goes stiff, whistles, drops or will not lock, one of those three has moved. Every one of them is a serviceable part.

    The usual sequence is that the stays wear first, because they carry the load. The sash drops a couple of millimetres, the cams start clipping the edges of the keeps instead of dropping into them, and the handle gets stiff. Keep forcing it and eventually something in the mechanism gives. Dealt with at the stiff stage it is an adjustment or a pair of stays. Dealt with after the mechanism fails it is a bigger job. That is the best argument there is for not living with a window that has started feeling wrong.

    Window seals, gaskets and draughts

    Seal problems are the single most common thing people ring us about in winter, and the word seal covers two completely different things, which is where the confusion starts.

    The first is the weather gasket, the rubber strip running round the frame and sash that the window compresses against when you close it. Over ten or fifteen years that rubber hardens, shrinks back at the corners and stops springing back. You feel it as a draught, you hear it as a whistle on a windy night, and sometimes you see it as rain getting in at the bottom corner. Replacing gasket is inexpensive, it does not involve taking the window out, and it makes an immediate difference to how a room feels.

    The second is the seal around the double glazed unit itself, the black edge you can see between the two panes if you look closely. That one cannot be replaced on its own. When it fails, moisture gets between the panes and the glass mists permanently, and the fix is a new sealed unit dropped into the existing frame. There is a full explanation in misted double glazing and on our glass unit replacement page.

    If you are not sure which one you have got, the test is simple. Draught and noise with clear glass is a gasket. Cloudiness or droplets between the panes that will not wipe off is a failed unit. Water on the inside face that wipes away is neither, and our window condensation page covers that one.

    The parts we change most

    Friction stays and hinges. The commonest replacement of the lot. Changed when a sash has dropped, when the window will not stay put in the wind, or when it has become heavy to open. Sold in sizes, so we measure before we bring them.

    Handles. Snapped, spinning, or seized. Espagnolette handles vary in spindle length and screw spacing between makes, which is why the one from the DIY shed frequently will not fit.

    Locking mechanisms and cams. The strip running round the sash edge. Replaced when the gearing is worn or a cam has sheared. Most patterns are still available and there is usually a modern equivalent for the ones that are not.

    Keeps and strike plates. The parts in the frame the cams engage with. Often the actual fix on a window that has been catching for years.

    Gaskets and weather seals. The draught and whistle fix described above. Cheap, quick, and the one most people leave far too long.

    Trickle vents. Broken flaps and seized sliders, which matter more than people think because they are part of how the room ventilates.

    Sealed glass units. Misted, blown or cracked. The unit is replaced and the frame stays exactly where it is.

    Restrictors and child safety catches. Replaced when they no longer hold, which is worth doing rather than ignoring.

    Keeping uPVC windows working

    uPVC windows are sold as maintenance free and they very nearly are, but the moving parts are still moving parts. Ten minutes twice a year is the difference between hardware lasting twenty years and hardware lasting eight.

    Put a light lubricant on the friction stays, the hinge points and the cams along the sash edge. A light oil or a dry PTFE spray, not a heavy grease, because grease collects grit and the grit is what wears things out. Wipe the gaskets with a damp cloth rather than letting dust and grit sit against them, since that is what hardens the rubber. And clear the drainage slots along the bottom of the frame, the little slots on the outside face, because when those block the water has nowhere to go.

    One more that costs nothing: open every window occasionally, even the ones you never use. Hardware that never moves seizes, and a window that has not been opened in four years is the one that gives trouble when you finally need it.

    If a set of windows has been left a long while, a full window service is better value than fixing one fault at a time. Stays checked and adjusted, keeps realigned, compression set properly, everything lubricated and the seals gone over, all in one visit.

    Every style of window we repair

    Standard casement windows are the bulk of it, but the same applies across flush sash, tilt and turn, reversible and vertical sliding sash windows, along with fixed lights, bays and triple glazed units. Aluminium and older timber frames we will look at too. Our window installers in Wishaw page sets out every style together.

    If it is a door rather than a window, our door repair page covers that side, and the doors in Wishaw page gathers all of it in one place.

    A few faults have their own guides worth reading before you ring. A window that rattles in the wind is usually compression rather than anything broken. A window that is draughty and stiff at once sounds like two problems and is normally one. And trickle vents are the part everybody blocks up and then wonders why the windows are streaming.

    Where we cover

    We are Wishaw based and work across most of Lanarkshire from there, including Motherwell, Hamilton, Bellshill, Airdrie and Coatbridge, along with Glasgow, East Kilbride, Carluke, Lanark and Livingston. If you are not sure whether we come out your way, phone and ask.

    Questions we get asked about window repairs

    Can you repair a window without replacing the frame?

    Nearly always, yes. The frame is normally the part that lasts. It is the moving and sealed parts, the hinges, handles, locks, gaskets and the glass unit itself, that wear out or fail. There is more on the decision in repairing or replacing windows.

    My window is misted. Is that a repair?

    Yes. A misted pane means the sealed unit has failed, not the window. We replace the glass and leave the frame where it is. Why double glazing mists up explains the cause, and what it costs to fix a misted window covers the money side.

    The window is stiff and draughty at the same time. Is that two jobs?

    Usually one. Stiffness and draughts often share a cause, a hinge that has dropped or a gasket that has gone hard, so the sash no longer sits square in the frame. See draughty and stiff windows.

    Is the work guaranteed?

    Yes, parts and workmanship both. If something we fitted is not right, we come back and sort it. Over thirty years in the trade and more than a hundred five star reviews on Google, which only happens if you turn up again when you are asked.

    Most of what we get called out to falls under the heading of double glazing repairs, whether that is a misted unit, a handle that has given up or a window that will not lock.

    Wishaw is our home town, so if that is where you are there is a fuller rundown on our windows in Wishaw page, which covers the repair side, the styles we fit and what drives the price of a replacement.

    Windows are one half of what we do. Our full list of services covers the doors side as well, and the frequently asked questions page answers most of what people ring up to check before booking.

    If the glass itself is broken rather than the hardware, that is a different job. See broken window repair for how we board up and reglaze.
