Slim Cavity Units for Llangefni properties
Most Slim Cavity Units enquiries we take in Llangefni start with an opening that is not a standard size. With slate-quarry terraces, Victorian resort stock and stone farmhouses making up much of the area, off-the-shelf sizes rarely line up. Set against severe Irish Sea exposure with very high rainfall, most joinery here eventually shows salt and rain combining to strip finishes and open glazing joints. What you are paying for is narrow cavities that perform while keeping the sightline historic.
The survey happens before manufacture, which is why our units fit without packing or trimming. Give us the basics and you will have a written figure, not a range that moves later.
A local consideration we always raise: Llandudno's Victorian frontages are protected as a coherent conservation set.
