Frequently Asked Questions — Extension Builders in Greenock

Do I need a building warrant for an extension in Greenock?

A single-storey rear extension typically costs £1,200–£1,800 per square metre; two-storey £1,000–£1,500 per sqm. A typical 4m × 5m single-storey extension might cost £25,000–£45,000 all-in. Always get at least 3 detailed quotes.

Do Greenock extension builders cover surrounding areas?

Yes — most extension builders based in Greenock cover the wider district including Port Glasgow, Gourock, Paisley, Glasgow and surrounding areas. Some also cover the wider Central Belt.

What qualifications should an extension builder in Greenock have?

Your builder should carry public liability insurance (at least £2 million), employer's liability if they have staff, and provide references. FMB or NHBC membership is a good sign. They should manage building warrants, structural engineers, and building control inspections.
