This beautiful traditional house was built in around 1920 and set in its own grounds. Our client was gazumped by a national builder when he was trying to purchase this property, the builders wanted to demolish this beautiful house and put a block of flats on it. However planning was refused and our client managed to purchase it after talks with the builders.

The outside walls was in very good condition considering no maintenance had been carried out on them for many years, and as a result minium preparation was required.The contract was completed and the client was very pleased with the results.A few years later the client contacted us to spray a new  kitchen extension to the rear of the propery. The results can be seen in the photos below.
*    Power-wash all external walls

*    Cut out and replace all defective bricks

*    Repoint all defective pointing

*    Mask up all areas not to be treated

*    Apply 2 coats of biocide

*    Apply a bagging coat to all raw bricks

*    Apply primer coat to all prepared areas

*    Apply by high pressure spray an ulta fine 
     textured elastomeric coating

*    On completion demask, remove all resulting 
      rubbish / debris and leave site in a clean and 
      tidy condition.
