We started A-S Building Services in 2018 with one rule — every project we finish should be one we'd happily live in ourselves.
Seven years on, that rule still runs the business. Most of our work comes from previous clients introducing us to the next, which means we treat every job as an interview for the one after it.
FMB-registered, TrustMark-endorsed, Master Builders members. The paperwork matters. The handshake on the doorstep matters more.
A predictable process is half the build. Here's how every project runs, from first call to final sign-off.
You tell us what you're imagining. We walk the site, ask the questions that save money later, and tell you honestly if we're the right team.
Itemised, transparent, fixed before the first brick is laid. You see every line: materials, labour, contingency.
One project lead, one tidy site, weekly progress photos, and the same faces from foundation pour to final coat.

Albert and the team built our rear extension last year. The work was clean, the communication was constant, and the finish was honestly better than we'd hoped. We've already booked them for the loft.Sarah & TomCaversham · Extension · 2025
