House Extensions in Erith That Add Space and Value

From modest single storey rear extensions to full double storey and wrap-around builds, Crest Building Services delivers house extensions across Erith that are designed to work for the way you live. Founder Wayne coordinates the structural brickwork in-house and brings in trusted, vetted trades for plumbing, electrics and finishing.

Erith is one of the many Greater London areas we serve, together with neighbouring Earlsfield and Foots Cray, all within comfortable reach of our Bexleyheath base.

What House Extensions in Erith Involves

We coordinate building regulations approval as part of the project and work with structural engineers where calculations are needed, such as steel beam specifications for opened-up spans. This is managed alongside the build so you are not left organising separate professionals yourself, and the finished extension is fully compliant rather than a job that struggles under scrutiny when you come to sell.

Timescales depend on the size and type of build. A single storey extension typically takes eight to twelve weeks from groundworks to completion, while a double storey extension usually takes twelve to eighteen weeks. Exact timing depends on the scope, the weather and how quickly design and planning decisions are finalised at the outset, all of which we talk through honestly before you commit.

With brick laying as Wayne's own specialism and a trusted network of trades behind him, your extension in Erith 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.
