The 10 best builders in Glasgow

For a home alteration, the right builder depends on whether you need a single trade or project management from planning to finish. Glasgow firms cover extensions, loft and garage conversions, kitchens, bathrooms, roofing and repairs. Check what is included in the quotation, who coordinates trades and whether a survey or site visit comes first.

Why they are in this order

Reputation alone does not decide the order. A business devoted to this work that has served its customers well for years ranks ahead of a bigger name that only dabbles in it.

Where a business pays to be featured, you will see it marked. That option exists only for businesses already chosen for the guide.
