Builders, electricians, plumbers and roofers for Seaham, Dawdon, Deneside, Murton and the Durham Heritage Coast. Every trade on our own books, one fixed price.

Seaham has changed from a pit and harbour town into one of the most popular places to live on the Durham coast. Sea views come with sea weather, and wind, rain and salt air are hard on roofs, render, windows and metal fixings.
We cover Seaham and the area around it, including Dawdon, Deneside, Parkside, New Seaham, Seaton, Murton, Cold Hesledon and the coast road towards Sunderland.

Seaham also has a lot of newer housing on the edges of town and on former colliery land. There, the work is usually extensions, kitchens, bathrooms, garage conversions and EV chargers.
On the coast we specify stainless or coated fixings, suitable render and roof systems for exposure. The area is former coalfield, so ground is checked before extension foundations are designed. Planning and Building Control are with Durham County Council.
