How a job runs

Six stages, the same on every project, so you always know what happens next and what it costs.

  1. First visit

    We come out, measure up and talk through what you want and what the building will actually allow. Usually an hour, always free.

  2. Written quote

    An itemised quote broken down by trade and stage, with a clear list of what is included and what is not. No verbal figures.

  3. Drawings and approvals

    Where you need them, we bring in our architect and structural engineer and handle building control and planning on your behalf.

  4. Programme agreed

    A dated schedule showing which trade is in which week, agreed before we start, with a fixed start date in writing.

  5. On site

    Dust sheets down, skip booked, and a photo update at the end of every week. Payments are staged against work completed, never up front.

  6. Handover

    We walk the job with you, snag it, and hand over certificates, guarantees and the building control completion notice.

What people say

They gave us a start date in January and turned up on it. The extension was watertight in three weeks and the price at the end was the price on the quote.

Whitley Bay · Rear extension
What sold us was the detail in the quote. Everyone else sent a number on a page. We got a breakdown we could actually understand.

Two kids in the house and they still kept it clean and safe every single day. A small thing, but it mattered for eight weeks.
