Building & Brickwork: common questions

Do you handle building regulations?

Yes. We work with building control and can recommend architects and structural engineers where drawings are needed.

Is repointing worth doing?

Yes, if the mortar is crumbling or recessed. Open joints let water into the wall, which leads to damp inside and frost damage to the bricks.

Do you do small building jobs?

Yes. No job is too small — repointing, a few courses of brickwork or a replacement lintel.

Can you do the roof on my extension?

That is exactly where we are different. We build the extension and roof it ourselves, so there is no gap between trades.
