Finlock Guttering

Product Details: Finlock gutters, (often known as concrete gutters) are constructed out of a series of profiled concrete blocks that together create a rainwater channel along the length of your property. During construction they were laid on top of your walls with mortar in the same way as a brick or concrete block.

Finlock concrete gutters were used post war due to a shortage of steel which was traditionally used and they have been causing homeowners trouble ever since.

Life Expectancy: Re-lining the Finlock with Rubberbond EPDM carries a 20 year guarantee with a 50+ life expectancy.

Personalisation: Finlock Guttering (concrete) can be removed and changed to UPVC guttering or re-lined with Rubberbond EPDM, depending on the customers preference.

It is very important when removing concrete gutters the work is carried out by a competent builder due to the structural nature of the concrete gutters. If not removed correctly this can cause significant damage to your home.

Why Do Finlock Concrete Gutters cause damp?

The main weaknesses on concrete gutters come from various causes;

  • The Joints - Over the years the mortar becomes permeable and leaks water directly from the gutter channel into your walls.

  • The Design - The concrete gutter blocks were laid level on a mortar bed during construction. This means they have no pitch or fall and do not allow the water to flow and often cause ponding. 

  • Cold Bridging - Each Finlock concrete guttering block is continuous, from its overhang outside to the inside wall of your home. If it is cold outside, heat is lost directly through the damp concrete guttering. This creates a cold spot at the top edge of your upstairs wall. When a house has been upgraded with draught proofing, double glazing, cavity insulation and modern central heating, these spots at the top of the walls become the coldest surfaces in the house. This causes all the condensation from the home to settle in these already problematic areas.

Lining concrete gutter

Whilst lining the gutter does not prevent the issue of cold bridging, it is a more affordable method of dealing with problematic concrete gutters. The guttering is lined with a Rubberbond EPDM membrane that has a guarantee of 20 years and a life expectancy of 50+ and is the same material we use for our flat roofing. This gives a waterproof lining to the gutter where the concrete may no longer be up to serving its original purpose.

Removing existing finlock concrete guttering

For customers who want to remove the concrete gutters this should always be done by a professional who has experience in removing them correctly. Due to the construction of the building and the initial installation of concrete gutters form part of the buildings structure if they are not cut off correctly, significant internal damage can be caused.  

Removal process;

  1. The first few rows of tiles are removed, and the roofing felt is stripped back.

  2. The existing concrete gutter is cut off in sections, level with the brickwork.

  3. The rafters are then extended where possible* to allow for an additional row of tiles to be installed for the alignment of the new guttering system. * this is not always required depending on the style of the property and can be done without.

  4. Timber lathes are installed to support an extra row of tiles and timber noggins are installed to the ends of the rafters to ensure a solid base to fix to.

  5. New felt is installed to the stripped area of tiles.

  6. The PVCu fascia boards (and soffit if rafters are extended) are installed to the timber noggins and new guttering system is installed to the fascia boards.

  7. The tiles are re-installed/ added to the roof, completing the process of converting concrete gutters to the new PVCu system.

The above process means that you will have a guttering system that collects rainwater outside of the property walls. This system will have a fall which means the water can flow in the correct direction to the downpipes and channel the rainwater away quickly.
