Halesowen sits on heavy Mercia Mudstone clay, and that soil type dominates every drainage job we do in B62 and B63. Heavy clay expands when it absorbs water in winter and contracts when it dries out in summer. That constant seasonal movement gradually opens up the joints in older clay pipes, creating the gaps that tree roots and groundwater find first. The drainage issues that homeowners in Halesowen contact us about most often start with a gurgling sound from a downstairs drain, which is usually the first sign that a root mass has started to restrict the pipe bore.
The 1930s semis that make up much of Halesowen's residential stock were built on original clay pipe drainage runs that are now 80 to 90 years old. These pipes have largely survived well, but the joints age and the surrounding clay soil continues to move around them. Shared drainage runs between neighbouring properties are common in the inter-war streets, and a single blockage frequently backs up into two or three homes. Our drainage engineers in Halesowen carry CCTV equipment on every job so we can trace the full run and find exactly where the blockage sits before we start jetting.
The 1960s estates across parts of Halesowen used pitch-fibre pipe as the standard material. Pitch-fibre blisters on the inside over time, reducing the bore of the pipe gradually until it blocks completely. When residents on these estates in Halesowen contact us for drain unblocking, it often involves a drain that has been slow for years before finally stopping. Jetting gives temporary relief, but the correct fix is relining or replacement. We carry relining equipment so we can give a long-term solution on the same visit where the pipe condition allows it.
Cradley Heath and Old Hill, to the north of the main town, have an industrial heritage from the chainmaking and nail-making trades. Former factory and forge sites have been redeveloped, but underground drainage from those uses sometimes survives in unexpected places. Drain unblocking Halesowen jobs in Cradley Heath occasionally turn into something more complex when the CCTV reveals an abandoned industrial connection or a redundant interceptor chamber that is now acting as an unplanned part of the drainage run. We cover the full surrounding area, and homeowners on the Stourbridge side of the boundary can find more localised detail on our drain unblocking in Stourbridge page, while those closer to south Birmingham may find our Birmingham drainage services page helpful.
