About Us

Over 40 years of damp proofing & lime rendering expertise

Britannia Group has been specialising in damp proofing and lime rendering for over 40 years, established in 1984. That experience sits behind every job we carry out, from small repairs to full property renovations.

Due to customers asking us to take on other aspects of construction work while we were already on site carrying out damp proofing and rendering, we now also offer electrical and plumbing services, carried out by qualified professionals.

In addition, we offer roofing services incorporating pitched roofing, flat roofing, guttering, fascias and soffit installation, carried out by professionals with over 40 years of experience.

2 causes of damp in kitchen of semi house

Rodney carried out the works himself, was friendly and cleared up afterwards. Rendering and painting was well executed and neat, a cast iron soil pipe renewed and a drip tray fitted to a side window. I was very pleased with his work and recommend him.

Rendering two exterior walls on detached house

Rod did a good job on the rendering and painting on the outside of the house. He was very conscientious and communicated well and also his quote was very competitive. Although some damage was done on the decking by the scaffolders, he followed everything up to get it repaired.
