Retrofit Double Glazing for Swansea properties
The hard part of Retrofit Double Glazing in Swansea is not the making, it is the measuring. You will find mostly valleys terraces, Victorian maritime villas and civic Portland stone frontages in this area, and it moves as it ages. Add very high rainfall with strong Atlantic and Bristol Channel exposure to that and prolonged wetting decay and finish failure on valley-facing elevations becomes the usual trigger for replacement. The value is in reworking the rebate so a sealed unit fits without bulking the section, not in the timber bill.
Manufacture only starts once the survey figures are agreed with you in writing. Send us sizes and a photograph and we will come back with a fixed written price.
Local factor worth flagging early: valleys terraces share a repeating bay and sash format that suits batch manufacture.
