About JAS Building Services

A family-run firm with two generations of building craft.

Established in North Bristol in 2010 and led by CEO Andrew Sperring — a former carpenter, foreman and APMP-qualified national project manager — JAS is a multi-award-winning building company with over 40 combined years of industry experience.

From bespoke kitchen and bathroom refits to Grade II* listed townhouse restorations and ground-up new builds, we operate with a dedicated office team, project managers and working supervisors — a structured, professional approach rarely found in the domestic building sector.
