House Refurbishment in Brentwood | RCB Design & Build
Full house refurbishments are our second-largest workload across Brentwood — period-property buyers typically take possession then refurbish before moving in. RCB Design & Build delivers house refurbishment projects right across Brentwood (CM14) from our Dartford base — typically on site within 48 hours of enquiry, with a fixed written quotation in 5 working days. Our typical house refurbishment project in Brentwood costs between £69,000 and £288,000 in 2026, with most inter-war detached and Arts and Crafts homes landing around £178,500. We are FMB, TrustMark, Checkatrade and TrustATrader accredited and operate as a Principal Contractor under CDM 2015.
Affluent commuter belt — large extensions, full refurbs and structural alterations. Working out of Brentwood Borough Council's area, we know the planners, the local building inspectors, and the named conservation officers — that personal relationship cuts weeks off the consenting timeline. Our typical Brentwood project is on inter-war detached within easy reach of Thorndon Country Park or the A12, and we work with a small panel of trusted Essex-area subcontractors we have used for years.
What's included in our house refurbishment price
Strip-out, structural alterations, full first-fix M&E (rewire, replumb, central heating), insulation upgrade where accessible, plasterboard and skim throughout, joinery, decoration. Second-fix kitchen/bathroom and finishes are client-supplied within agreed allowances. Our written quotation covers labour, first-fix materials, project management, scaffolding, skips, Building Control fees and statutory inspections. Second-fix materials (kitchens, bathrooms, flooring, tiles, paint, sanitaryware) are supplied by the client as a deliberate cost-control measure — this typically saves homeowners £14,280–£26,775 in trade markup. We exclude planning fees, party-wall surveyor fees and structural engineer drawings, which we coordinate at cost.
Brentwood planning, party walls and Building Regs
High proportion of conservation areas in central Brentwood and Hutton; Green Belt restricts edge sites. Always survey for asbestos (pre-2000 housing), check joist depths before opening floors, and test the electrical earthing system before any rewire price is committed. Note that Brentwood has multiple conservation areas — design must match prevailing materials, roof shape and fenestration. Party Wall Awards are typically needed for any excavation within 3 metres of a shared wall — we coordinate the surveyor and serve notices. Building Control is lodged at the start, with inspections at foundation, damp-course, pre-plaster and completion stages.
Timeline and process for Brentwood projects
Full refurbs run 14–22 weeks on site for a typical 100–140 m² mid-terrace. Mid-renovation site visits happen weekly and we send a written report every Friday. We hold a weekly call with the client throughout, send a written progress report with photos every Friday, and the lead PM is always reachable on WhatsApp. From CM14 postcodes we can have someone on site within 48 hours of a phone call.
Guarantees and after-care
Every project we deliver in Brentwood is backed by a 12-month workmanship guarantee. Where we install manufacturer-warranted systems (roofing membranes, windows, MVHR), the manufacturer warranty (typically 10–25 years) runs alongside. As an FMB member we can also arrange an FMB-backed 2-year insurance warranty on qualifying Brentwood schemes — worth considering for any project above £50,000.
