Until relatively recently, drainage companies would use metal pipes rather than PVC when installing systems within homes. Typically, they would use cast iron metal pipes. This material has a very long lifespan, but after a few decades (some of these pipes were installed as far back as the 19th century!), their integrity has become compromised, and the whole system will begin to see significant issues.

Unlike plastic, cast iron is subject to a number of issues which can quickly reduce its lifespan. Although it is tough, it is susceptible to problems like corrosion and scale, which means older pipes could suffer a critical crack or full-on collapse without warning. For older pipes suffering repeated issues, the best option is often to have the whole system updated.

This might sound like an incredibly expensive option, but with Clark Drainage you can be confident that you will receive the very best service at a reasonable price. Using our well-trained and well-equipped teams of technicians, we are able to offer practical, efficient, and affordable solutions. To arrange a job today, give us a call on 0808 164 0776.

Problems with Old Metal Pipes

The two most common problems with old cast iron pipes are, as mentioned previously:

  • Corrosion
  • Calcification

Problems with Old Metal Pipes

Corrosion: As we all know, iron will rust as time passes. The moisture in the air is enough to cause steady corrosion; now imagine iron that continually has water running through it. Given enough time, the rust will spread throughout the entire pipe and can create holes or cracks in the pipeline.

The best-case scenario is that a crack will appear which will reveal damp to you. In this case, we can come in and fix the situation before things get any worse. In the worst case, the pipe will collapse entirely, leading to widespread flooding and, in turn, expensive repairs.

Calcification: In areas with hard water, scaling can cause severe problems within your drainage system. Hard water, such as in regions throughout the South and East of England, is full of minerals. These minerals will build up over time, clinging to the side of the pipe.

Given enough time, these scale deposits will turn into a blockage which the water can’t flow past. At this stage, you will either have to get the scale removed professionally, or more ideally, have the system updated and modernised.

Buying an Old House

Old houses have a lot of character and can be an incredibly worthwhile and rewarding investment. However, they can also come with a lot of problems, which turn your investment into an expensive, ongoing, and unwelcome project.

One step you can take when buying an old house from the 40s, 30s, or even earlier, is to have a CCTV Drain Survey carried out. This process will highlight the exact state of affairs within the pipes and will allow our technicians to give you an accurate quote on how much it will cost to fix.

You might think that a drain survey is an unnecessary expense, but a drainage system in disrepair can turn your dream home into a nightmare. To arrange a CCTV Drain Survey, give us a call today on 0808 164 0776.

Drainage System Replacements

If you think your drainage system might be in need of replacement, it is best to have it updated sooner rather than later. While the expense might not be welcome, it will be significantly cheaper than having to repair after the water damage from a widespread flood.

    I had no clue what was going on with our pipes but they explained it all so clearly. Felt completely reassured the whole time and appreciated how patient they were with my questions.

    Didn’t let us down.

    They were recommended by a mate and didn’t disappoint. From the first phone call to the final clean-up, it was clear they knew their stuff. We felt confident we were in good hands the entire time.

    Surprisingly brilliant.

    Never thought I’d be raving about a drain company but here we are. They were just that good. Helpful, friendly, honest – and most importantly, they fixed the problem without any stress.

    Detailed and really useful.

    Had a CCTV survey done. Report was super detailed and made it easy for our builder.

    Garden sorted, no more flooding.

    Cheers to Clark Drainage for getting our garden sorted after that downpour. Great job. We’d tried a few things ourselves with no luck, but they came in, identified the issue quickly, and had the drainage working perfectly again.

  • 17/08/2025

    Quick turnaround and sorted fast.

    The lads came out next day and fixed the issue in half an hour. It had been bothering us for weeks, so to see it sorted that quickly was honestly a huge relief.

  • 16/08/2025

    Did it right first time.

    We’d had other companies round who couldn’t fix it. Clark Drainage had it sorted in one visit. The difference in professionalism and competence was night and day. Absolutely brilliant from start to finish.

  • 14/08/2025

    Proper pride in their work.

    It’s not glamorous work but they do it with a smile and real pride. Can’t say I’ve ever seen someone so happy clearing a drain, but they made the whole thing stress-free and even a bit fun.
