Specialise in stairs, fitted wardrobes or complex interiors and progress to installation responsibility.

Frequently asked questions

Why measure again when drawings exist?

Finished floors, plaster and corners may differ from design dimensions. Site checks prevent a correctly manufactured part from failing to fit.
