For double glazing repair in Allerton we replace misted or broken sealed units, renew worn hinges, handles and window locks, and fit new seals in existing uPVC, aluminium and composite frames. Much of Allerton (L18, with parts in L19) is inter-war semis and detached houses, and their bay windows often carry several older units that fail one by one. We look, measure, quote in writing and fit made-to-measure glass on a second visit.
Why do bay windows in Allerton give so much trouble?
A typical Allerton bay has three or more facets, each with its own sealed units and often its own opening sash. That means more edge seals, more hinges and more joints where the bay meets the brickwork. When these houses had their original windows replaced with uPVC, bays were usually fitted with angled couplers or bay poles between the frames. Decades later, the problems we see tend to be:
- One or two panes turning cloudy while the rest stay clear, because each unit ages at its own rate.
- Top lights or opening sashes that have dropped on worn friction stays and now rub or refuse to lock.
- Draughts at the coupling joints where gaskets have shrunk.
- Water sitting in the bottom of the frame where drainage slots have silted up, which can shorten the life of the glass units above it.
Our page on misted sealed units explains why a fogged pane cannot be wiped clear and why the lasting fix is a new unit made to size.
Repairs we carry out on Allerton homes
Glass units
We measure each failed pane, order a new insulating glass unit to suit, and fit it into your existing frame with fresh packers and beads. Where the old units are working but simply old, some owners choose to swap them for modern low-E, argon-filled units; our energy-efficient glass upgrade page covers that option honestly.
Hinges, handles and locks
Bay and side casements in these houses get heavy use for ventilation. Worn uPVC window hinges are a frequent call-out, as are espagnolette gears that slip when the handle turns. Small hardware jobs can often be done at the first visit if we carry the right part.
Seals
Shrunken wedge gaskets around the glass and tired bubble seals on the sashes let in cold air and rain. Most can be replaced without disturbing the frame.
A quick check you can do first
Before you call, look closely at any window that seems foggy. If the moisture is on the room side and wipes off, it is condensation from the air inside the house, not a failed unit. If it is outside early on a cold morning, that is normal for efficient glass. Only moisture trapped between the panes points to a broken edge seal. While you are there, brush out the drainage slots along the bottom of the outer frame; it is a simple job that helps keep water away from the units.
If any pane is cracked or broken, keep children and pets away and do not pull loose glass from the frame. Call us and we can make the window safe before a replacement unit is fitted.
Nearby areas
Allerton sits between several suburbs we also cover. To the north-east, Childwall has a similar mix of inter-war semis; further south-east, Woolton combines village properties with newer suburban houses; and towards the city, Wavertree has older terraces.

Frequently asked questions
Can you replace just one misted pane in my bay window?
Yes. Each pane in a bay is normally its own sealed unit, so a single misted unit can be measured, made and fitted on its own. The other panes stay as they are. If several in the same bay have started to fog, it can be worth doing them together so the bay looks even.
Will new glass units look different from my old ones?
Sometimes slightly. Spacer bar colour, glass tint and any Georgian bars vary between makers and ages. At the survey we look at what you have and talk through how close a match is possible, including obscure patterns on side or landing windows.
My bay window casement drops when I open it. Is that the hinge?
Very often. Friction stay hinges wear and loosen with age, and a sagging sash then catches the frame or will not lock. Replacing the hinges, like-for-like on any escape window, usually brings the sash back into line.
Do you cover the parts of Allerton with an L19 postcode?
Yes. We work across Allerton in L18 and the neighbouring L19 streets, and on into Mossley Hill, Garston and Aigburth on request. Tell us your postcode when you call and we can arrange a visit.
Is it worth repairing older uPVC windows rather than replacing them?
If the frames are sound, square and still lock, swapping failed glass units, hinges and seals is usually far less disruptive than full replacement. Where a frame is cracked, badly distorted or rotten at the subframe, we will tell you plainly that a repair is not sensible.
