    // What you get

    Extensions done properly in Brentwood.

    We've done a lot of work in and around Brentwood over the years, mostly extensions and full home renovations on the older properties around Hutton and Shenfield. The roads are tight and the neighbours are close, so we keep the site clean, the skip tucked in, and the radio at a sensible volume.

    • Single and double-storey rear extensions
    • Kitchen-diner side returns with bi-folds and roof lanterns
    • Loft conversions including dormers and Velux
    • Building Control and structural engineer co-ordination

    Why Brentwood homeowners call us first.

    Brentwood extensions often need conservation-area attention to detail - matching brick, lime mortar, the works. Brentwood (CM13 – CM15) sits well inside our regular run, so getting out for a quote is no trouble and there's no call-out fee.

    Property-wise, Brentwood is older detached homes around Hutton and Shenfield, with tighter Victorian terraces nearer the high street. That matters for extensions because every job has its own quirks - what works in a 1930s semi doesn't always suit a new build, and we plan accordingly. Roads are tight in places, so we keep the skip tucked in and the site clean.

    Recent extensions jobs have taken us into Hutton, Shenfield, Warley, Ingatestone, Pilgrims Hatch, Doddinghurst and Herongate - so if you're in or near Brentwood, we're probably on your road most weeks anyway.

    When you ask us for extensions in Brentwood, you get one team for the whole job, a fixed written quote before we start, and a single point of contact from first visit to handover. No subcontractors disappearing halfway, no surprise extras on the invoice.
