Builders in Glasgow

Phone numbers for builders covering Glasgow — extensions, loft conversions and refurbishment. Open a profile and call the business yourself. This site does not send your job.

Extensions and loft work need more than a day rate. The renovation budget tool can sit beside a local quote. Paisley and Clydebank cards sometimes say Glasgow. Ask which close they will climb, and do not use this page for Edinburgh's New Town or Aberdeen granite. Profiles show a name, the area they cover and a phone number. Public qualifications such as Gas Safe or NICEIC appear only when they are on the profile. Read the cost notes for a sourced national range; a figure on a card is not a quote.

Typical building & conversions costs

Checkatrade’s house-extension guide, per-square-metre table last updated March 2025, is a national sense-check for shell versus finished work. It is not a local tariff. Taking down a wall in a tenement can be the mutual structure. Ask if a warrant and a structural note are included, or if the price assumes a stud in a modern flat in Finnieston.

A local rule to check in Glasgow

Many extensions, loft conversions and structural openings need building control, and some need planning. A listing is not an approval and not a party-wall agreement.

Questions before you phone

How do I find builders in Glasgow on this list?

Dennistoun and the west end are sandstone tenements with a close stair and no lift. A three-storey walk-up decides the job before the trade does, because everything comes up on foot. Names, service areas and phone numbers sit on the cards. Open a profile and call the firm yourself. Paisley and Clydebank cards sometimes say Glasgow. Ask which close they will climb, and do not use this page for Edinburgh's New Town or Aberdeen granite.

Does this page send my job to a Glasgow building & conversions firm?

No. You place the call. This site does not email or text anyone on your behalf.

What should the written price say for building & conversions in Glasgow?

Warrant and engineer should be lines if a structural wall is mentioned. A stud partition in a new flat is a different sheet of paper.

What is easy to miss before booking in Glasgow?

The close is common property. Drilling a flue through a stair wall, or leaving a boiler in the turn of the landing, needs the other owners, not only the flat.
