Concrete Gutters can impact your family’s health, your property, and your pocket!

Age and weather conditions will cause concrete gutters and Finlock gutters to move and shift, resulting in breaks of joints between blocks causing leaks, building damage and possible collapse of external guttering. This also leads to problems with damp arising in the walls and in the loft, as well as potential mould growth.

Replacing your concrete gutters will put a stop to this, and prevent any further collapse of the Finlock concrete guttering. Thermal bridging and thermal differentiation are other problems that only our guttering will solve.

Concrete Gutter Problems


Concrete gutters or Finlock gutters were installed during the 1950s, '60s, and '70s to carry out a dual function of closing the cavity at the top of the brickwork and providing a wrongly assumed maintenance free gutter system.


The gutters comprise of units that vary in length between 200mm and 600mm. The joints have either been sealed with bitumen or a similar substance, or the gutters are lined (often with a torch on mineral felt).
