General builderswork may be a vague term but includes many sections of works which form the basis of any alteration/ refurbishment or upgrade.
We carry in house bricklayers, plasterers, roughcasters and ground workers to name a few for works from foundations through brick/ block walling and wall coverings.
You will no doubt have heard the term "Timber Kit" and seen these in new builds where a timber frame is erected then covered in brick or blockwork, we consider the walling as a builderswork item even although our joiners have a large input into the timber side of things.
