A multi-trade renovation team that does the prep properly.
Core Build Group is a multi-trade renovation contractor based in Berkshire, working across London. We cover six trades under one contract — and the thing that distinguishes the work is what happens before the visible work begins.
Multi-trade. One contract. Fixed price.
We cover decorating, flooring, kitchen fitting, bathroom fitting, handyman & property maintenance, and building management. One project manager coordinates the job from the first site visit to the final snag — you deal with one number, one invoice.
Every job starts with a free site survey. We quote a fixed price after that visit — the number you sign is the number you pay. If something genuinely unexpected appears mid-job, we stop, show you, and agree before we continue. That is the only exception.
Based in Berkshire, working across London. We travel for the right job — call us if you are not sure we cover your area and we will tell you honestly.
Three rules that decide how every job runs.
Not values on a poster. Actual operating principles — the ones every project manager is held to on every job.
The quote you sign is the quote you pay.
We don't win work with a low estimate and renegotiate once we're on site. We quote accurately after a real site visit. If something genuinely unexpected appears mid-job, we stop, show you, and agree separately before continuing. That's the only exception.
The boring prep is where the job is won or lost.
90% of what makes a renovation hold up long-term happens before the visible work begins. Surface prep. Subfloor levelling. Tanking. Acclimatisation. The easy profit is always in skipping these. We don't.
One team. One number. One bill.
You talk to one project manager from the first site visit to the final snag. They run the trades, they know the brief, they own the outcome. One invoice covering everything agreed in the quote — no spreadsheet of subcontractors to chase yourself.
