Retrofit Double Glazing for Llanelli properties
Most Retrofit Double Glazing enquiries we take in Llanelli start with an opening that is not a standard size. You are mostly dealing with valleys terraces, Victorian maritime villas and civic Portland stone frontages around here, so openings vary more than people expect. Set against very high rainfall with strong Atlantic and Bristol Channel exposure, most joinery here eventually shows prolonged wetting decay and finish failure on valley-facing elevations. The detail we will not compromise on is reworking the rebate so a sealed unit fits without bulking the section.
The survey happens before manufacture, which is why our units fit without packing or trimming. Tell us what you are working with and we will put a fixed figure in writing.
One thing that catches people out here: valleys terraces share a repeating bay and sash format that suits batch manufacture.
