Frequently Asked Questions — CCTV Drain Survey Harrow

What drainage problems are most common in Harrow's interwar semi-detached houses?
Harrow's substantial stock of 1920s and 1930s semi-detached houses typically has clay drainage in variable condition. The most common defects found during CCTV surveys are joint displacement caused by London clay ground movement, root ingress from front and rear garden trees, and deteriorated inspection chamber benching. Properties with extensions added in the 1970s and 1980s frequently have informal drainage connections that were not made to building regulations standard.
Does Harrow's clay geology cause specific drainage issues?
Yes. Harrow sits on London clay, which is one of the most active geological formations in the south of England. The clay shrinks during dry summers and expands in wet winters, a cycle that continuously displaces pipe joints and causes cracking in clay drain barrels. This is the primary cause of root ingress in Harrow's drainage — once a joint opens, tree roots penetrate with ease. Properties with mature garden or street trees are at particular risk.
How long does a drain survey take in a Harrow semi-detached house?
A standard CCTV drain survey for a three- or four-bedroom Harrow semi-detached house typically takes 90 minutes to two hours on site. We provide a WRC condition-graded report with drainage plan within 24 hours.
Do you cover all of the Harrow postcodes?
Yes. We cover HA1, HA2, and HA3 across Harrow-on-the-Hill, Wealdstone, Kenton, Pinner, and all surrounding areas. Same-day and next-day availability in most cases.
