House Extension Builders in Keston Mark

Every house extension Crest Building Services builds in Keston Mark is designed around how your household really lives, not a fixed off-the-shelf package. Founder Wayne guides you from the initial site visit through design, planning and construction, applying his bricklaying specialism to the structural work that underpins the finished space.

We regularly work on properties in Keston Mark and the surrounding Greater London areas such as Keston and Kevingtown, so a site visit is never a long distance exercise.

What House Extensions in Keston Mark Involves

A written quote covers groundworks, structural brickwork, roofing and the coordination of the subcontracted trades needed to complete the shell, such as plumbing and electrics. You get a clear breakdown at the consultation stage so you know exactly what is and is not included before agreeing to proceed, with no vague figures or hidden extras appearing later in the build.

The process starts with a site visit to discuss your goals, budget and the practical constraints of your plot. From there we help develop workable designs and advise on planning permission and building regulations before any work begins. Once the plan is agreed, Wayne leads the groundworks and structural brickwork, with vetted subcontractors brought in for plumbing, electrics and finishing, and a final walk-through confirms every detail before handover.

With brick laying as Wayne's own specialism and a trusted network of trades behind him, your extension in Keston Mark is built by people who take the structural work personally. Get in touch to arrange your consultation and see how a properly built extension can add the space and value your home needs.
