Power or control faults

Transformers, control units, switches and remotes fail; we check these first.

Seal or hinge problems

A twisted hinge or worn seal stops the vent closing tight.

About Lerwick and the ZE1 area

Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

We cover Lerwick by arrangement: island work is planned around ferry access, and any travel or access costs are set out in your written quote before you commit.
