Secondary Glazing for Merthyr Tydfil properties
Half the Secondary Glazing problems we fix in Merthyr Tydfil started as a sizing assumption. You will find mostly valleys terraces, Victorian maritime villas and civic Portland stone frontages in this area, and it moves as it ages. With very high rainfall with strong Atlantic and Bristol Channel exposure in the mix, prolonged wetting decay and finish failure on valley-facing elevations is a question of when rather than whether. The part that matters is internal glazing that leaves the original window entirely untouched.
Each opening is recorded individually, since a terrace of identical houses rarely is. Send what you have, even if it is only a phone photo, and we will take it from there.
Bear in mind for this area: valleys terraces share a repeating bay and sash format that suits batch manufacture.
