Common Causes Of Pipe Leaks In Older Properties

First, let’s understand why pipes in older buildings tend to give out.

• Age and wear: Older homes often have steel or copper plumbing, which corrodes over time.
• Movement in foundations or walls can shift pipes and create stress on joints.
• Minerals build-up: Particularly in hard water areas, mineral deposits can block pipes and create pressure build-up.
• Freezing and thawing cycles: Cold weather can cause older pipes to crack or burst.
• Poor past repairs or DIY fixes: Temporary solutions often cause more problems down the line.

Knowing the root cause can help guide leak repair techniques and prevent future issues.

How To Fix A Leaking Pipe: Step-By-Step

Here’s a simplified version of the process, suitable for minor leaks in accessible areas.

Step 1: Turn Off The Water Supply

Always shut off the water at the main valve before starting. This prevents further damage and gives you a clean slate to work on.

Step 2: Drain The Pipes

Open the taps to remove any water still sitting in the pipes. This also relieves pressure and avoids a surprise splash during the repair.

Step 3: Locate The Leak

Use the methods mentioned earlier. You may need to cut into the plasterboard to access the pipe if it’s behind a wall.

Step 4: Choose The Right Fix

This depends on the damage:

• For small pinhole leaks, use leak-sealing tape as a temporary fix.
• For cracks or loose joints, you may need to replace a section using pipe connectors or compression fittings.
• Replacement with modern plastic piping is often the best long-term solution for corroded metal pipes.

Ensure you have the right leaking pipes repairing tools—pipe cutters, spanners, sealant, and possibly a blowtorch if you’re working with copper.

Step 5: Test Your Work

Once repaired, slowly turn the water back on and watch the area. If it stays dry, you’ve succeeded. If not, it’s time to call in professionals.

Leaking Pipe Repair Costs: What To Expect

Leaking pipe repair costs vary depending on the size and location of the problem:

• Minor leak (visible, accessible): £75–£150
• Wall or floor access required: £200–£500
• Complete pipe replacement: £500+ depending on materials and labour
• Emergency call-out: Expect additional fees for out-of-hours service

Regular pipe maintenance can reduce the likelihood of large repairs and spread the cost over time.

How To Prevent Future Leaks

Once you’ve dealt with a leak, take steps to avoid future issues:

• Schedule annual plumbing maintenance services
• Insulate exposed pipes to prevent freezing
• Replace outdated materials (like lead or steel pipes)
• Monitor your water pressure—too much can stress the system
• Fix minor issues early to prevent escalation

Think of maintenance as insurance for your plumbing system—especially in older homes.

When To Call A Professional

While a confident DIYer can handle minor issues, older properties often have hidden problems. If you spot recurring leaks, damage to multiple areas, or poor previous work, it’s best to seek expert help.

Plumbing maintenance services can also identify issues before they become emergencies. A small investment now can prevent major expenses later.
