Finlock gutters, also known as concrete gutters, were commonly installed on homes in the UK between the 1950s and 1970s as a low-maintenance alternative to metal guttering. Cast from concrete and integrated into the structure of the property, Finlock guttering became popular for its solid construction and durability. However, many homeowners have since encountered ongoing issues due to wear, thermal bridging, and water ingress. If you own a property with concrete gutters, professional repair, lining, or replacement is often necessary to maintain structural integrity and prevent damp-related problems.
Unlike modern uPVC guttering systems which are separate from the wall structure, Finlock gutters are built directly into the top of the cavity wall, often serving a dual purpose by supporting the first row of roof tiles. While this design was innovative at the time, it presents challenges today. Concrete is porous and can absorb water over time, especially when surface coatings degrade. This can lead to internal damp patches, cold bridging, mould growth, and even cracking within the concrete itself.
Common signs that your Finlock guttering may need attention include:
To address these issues, we offer several expert services tailored to the condition of your concrete guttering. One option is Finlock gutter lining, which involves fitting a watertight uPVC or rubberised membrane inside the existing gutter. This solution restores functionality, prevents further water ingress, and extends the life of the system without altering the building’s appearance. Lining is a cost-effective approach when the concrete structure is still sound but needs waterproofing.
In more severe cases — where cracking, movement, or significant damp is present — we recommend Finlock gutter removal and replacement. This involves carefully cutting away the concrete gutters and replacing them with modern uPVC fascia boards and a high-performance guttering system. Not only does this solve the problem long-term, but it also improves the look of your property and increases its thermal efficiency by eliminating cold bridging at the wall plate level.
Our Finlock gutter removal process includes insulating and sealing the exposed cavity walls, fixing new fascia and soffit boards, and fitting reliable, low-maintenance uPVC or aluminium gutters. This dramatically reduces the risk of internal damp and protects your home for decades to come. We take care to blend the new roofline visually with your existing features and use high-quality materials that resist warping, cracking, and UV degradation.
All work is carried out by trained professionals with experience in handling concrete gutter systems. We provide clear quotations, before-and-after photos, and full guarantees on both materials and workmanship. Our team works with care and precision to ensure minimal disruption and long-lasting results.
