Double Glazing Repairs in Canterbury, Kent

Misting between the panes means the sealed unit has failed. Double glazing works because the two panes are bonded around the edges to trap an insulating layer of air or gas between them. Over time, that edge seal can break down, often due to age, sun exposure, or moisture sitting in the frame, and once it does, damp air finds its way in and condenses on the inside faces of the glass where you can't wipe it away.

The good news is that a misted unit is a repair, not a replacement job. The glass unit itself is swapped for a new sealed one while your existing frame stays exactly where it is. Misting usually gets worse over time and a failed unit also loses much of its insulating performance, so it's worth dealing with sooner rather than later. If you've spotted fog, droplets or a milky patch between your panes anywhere in Canterbury, give us a call and we'll take a look.

It's a straightforward process. First we visit to measure the failed unit precisely, checking the thickness, spacer size and glass type as well as the dimensions, because sealed units are made to order for an exact fit. We then have your replacement unit manufactured to those measurements and return to fit it, removing the old unit, cleaning up the frame and beading, and installing the new glass cleanly and securely.

The fitting itself typically takes well under an hour per window, and the wait for a made-to-order unit is usually a matter of days depending on the glass type. Your frames, handles and locks all stay in place throughout, and there's no mess or redecorating involved. If several units around your home have failed, we can measure them all in a single visit and fit the replacements together, which keeps the cost and disruption down.

Yes. Double glazing problems aren't limited to standard windows, and we regularly work on sliding patio doors, French doors, bifolds and conservatories across Canterbury and Kent. These larger glazed units are just as prone to seal failure and misting, and their moving parts, rollers, hinges, restrictors and locking mechanisms, tend to wear faster because of how heavily they're used.

We can replace failed sealed units in doors and conservatory frames, sort sliding doors that have become heavy or juddery, and repair or replace the locking systems that keep them secure. Larger units sometimes need two people or specialist handling, which we'll flag when we quote, but the principle is the same as any other repair: fix what's failed, keep the frames you have, and avoid the cost of replacing the whole thing unless it's genuinely needed.

Yes, and it's a smart time to do it. Because sealed units are made to order, replacing a failed one is the perfect opportunity to upgrade the glass itself without touching the frame. Modern energy-efficient units with low-emissivity coatings and argon gas filling insulate noticeably better than units made fifteen or twenty years ago, which helps with heating bills and cuts down on cold spots and condensation on the room side of the glass.

There are other options too, depending on the window: acoustic glass for rooms facing a busy road, toughened or laminated safety glass where regulations or security call for it, and obscure or patterned glass for bathrooms. We'll talk you through what's worthwhile for your particular window and what isn't, the upgrade cost over a standard unit is often smaller than people expect, and we'll only recommend it where it genuinely adds value.

Usually, yes. A dropped window or door is one of the most common double glazing problems we see, and it rarely means anything is broken beyond repair. Hinges work loose or wear over time, and in uPVC doors the glass itself can settle within the frame, pulling the whole door out of square so it catches, scrapes or won't latch. It often shows up seasonally too, as frames expand in warm weather.

The fix is realignment rather than replacement. We adjust or replace worn hinges, and where a door has dropped we can repack the glazing within the frame, a technique called toe and heeling, to square the door back up so it closes smoothly and locks properly again. It's a quick, inexpensive repair, and worth doing promptly, because a door that's forced to lock puts strain on the whole mechanism and leads to bigger failures down the line.
