Inside the project
Every window in a 1930s detached, replaced in three weeks
The brief
A 1930s detached home in Bowdon with original bay windows and a full set of openings that had passed the point where repair made sense. Houses of this era have generous window openings and deep bays, which is exactly why they feel cold: there is a lot of glass and, in the original frames, very little to stop heat leaving through it.
Why triple glazing here
Triple glazing is not automatically the right answer, and we say so when it is not. On this house it was, because the glazed area is large, several elevations face north and east, and the owners were staying long term. Where the glass area is small or the house is a short-term hold, the extra pane rarely pays for itself and we recommend A-rated double instead.
The bays
Bay windows are the part of a 1930s house most often got wrong. The bay carries load from above, so the replacement needs a properly engineered structural head rather than window frames wedged into the opening and hoped for. We survey the existing support, specify the head, and fit it before the frames go in. Getting that wrong is what causes the sagging and cracking you see on cheap bay replacements a few years later.
Matching the house
The original glazing pattern was retained, with bar spacing set to match what was there rather than to a standard grid. On a 1930s frontage the proportions of the glazing bars are most of what makes the house look right, and a replacement that ignores them is obvious from the street even when the frames themselves are good.
On site
Three weeks, working room by room so the house stayed habitable throughout. Every opening was taken out and made good the same day, so nothing was left open overnight. Frames were made to the surveyed sizes at Trafford Park, which meant no packing out gaps and no cut-down standard units.
Whole-house glazing in Bowdon and Altrincham
Bowdon and the streets around it are dominated by large inter-war and Victorian detached houses: generous rooms, big window openings and, in their original state, a great deal of heat going out through the glass. A whole-house replacement here is a bigger job than the same brief on a modern estate, because there are more openings, several are bays, and the proportions have to be respected.
Doing every window in one programme rather than a few at a time costs less per opening, because the survey, the manufacturing run, the delivery and the fitting team are all shared. It also means the elevation ends up consistent, which matters on a house where all the windows are visible from the street at once.

Is triple glazing worth it for you?
Not always, and we would rather say so. Here is roughly how the decision goes.
- Probably not, on its own
- If the house already has sound double glazing and decent insulation, the payback on heat alone is long. Triple is not a free upgrade and we will not pretend it is.
- Probably yes, in these cases
- A room that is always the coldest in the house, an elevation that takes the weather, or a whole-house replacement where the marginal cost per window is small rather than a separate decision.
- If noise is the real problem
- Say so, because triple is not the answer. Mass and mismatched pane thicknesses beat a third pane for sound, and an acoustic double unit will usually outperform a standard triple for less.
- Weight has consequences
- A triple unit is significantly heavier. Hinges and hardware must be specified for it, which is one reason reglazing an old frame with triple is rarely the bargain it looks like.
