Repair pipework.

Left untreated, even a minor drip can lead to damp, rot, and mould growth within the fabric of your home. Professional pipe repair ensures your plumbing system remains watertight, compliant with local water regulations, and operates at the correct pressure.

What Does the Work Involve?

• Inspection and Detection: Locating the source of the leak, which may involve "trace and access" techniques if pipes are hidden behind walls or under floorboards.
• Isolation: Shutting off the water supply via the internal stopcock or external water meter to prevent further flooding.
• Access: Carefully removing floorboards, tiles, or small sections of plasterboard to reach the damaged section.
• Pipe Replacement: Cutting out the compromised section and installing new copper, PEX, or barrier pipe using appropriate fittings (soldered, compression, or push-fit).
• Testing: Re-pressurising the system to ensure the new joints are sound and checking for secondary leaks elsewhere in the circuit.
• Reinstatement: Advising on the necessary drying time and repairs needed for walls or floors disturbed during the process.

Typical Costs

The total cost is primarily driven by accessibility. A visible pipe under a kitchen sink is a quick, cheap fix, whereas a leak beneath a concrete floor or behind expensive tiling will require significantly more labour and reinstatement work.

How Long Does It Take?

• Simple visible leak: 1–2 hours (e.g., a leaking joint under a sink or radiator valve).
• Hidden leak under floorboards: 3–5 hours (including time to lift and relay flooring).
• External mains repair: 1–2 days (if excavation and backfilling are required).
• Full system drain-down: Adds 1–2 hours to the job depending on the size of the property.

DIY or Professional?

While a confident DIYer can fix a simple push-fit joint, professional intervention is highly recommended for most pipe repairs. Incorrectly installed fittings can fail under pressure, leading to catastrophic flooding that may not be covered by your home insurance if the work wasn't carried out by a competent person.

Most UK home insurance policies include "Trace and Access" cover, but many will only pay out if the repair is completed by a qualified professional.

Choosing the Right Tradesperson

• Check Qualifications: Look for plumbers registered with CIPHE (Chartered Institute of Plumbing and Heating Engineering) or WaterSafe.
• Insurance: Ensure they hold Public Liability Insurance (minimum £2 million) to cover any accidental water damage.
• Red Flags: Avoid tradespeople who refuse to provide a written quote or those who cannot explain how they will access the leak without causing excessive damage.
• Questions to Ask:
  • Are you WaterSafe registered?
  • Does your quote include the cost of making good (plastering/flooring)?
  • What guarantee do you provide on the new fittings?
  • Can you provide a report for my insurance company?

UK Regulations

• Water Supply (Water Fittings) Regulations 1999: All repairs must prevent contamination and waste of the water supply.
• Part G (Building Regulations): Covers sanitation, hot water safety, and water efficiency.
• Part L: Relevant if the pipe repair involves the central heating system and insulation requirements.
• Paperwork: For major works, you should receive a certificate of compliance or a detailed invoice stating the work meets current Water Regs.

Common Problems

• Incompatible Materials: Joining old lead pipes to modern copper using incorrect fittings, leading to "galvanic corrosion."
• Hidden Damage: Fixing one leak only for the increased pressure to cause a second leak in a weakened section of old pipework.
• Poor Insulation: Failing to lag repaired pipes in unheated areas (like lofts), leading to future bursts during winter.
• Inaccessible Stopcocks: Homeowners often don't know where their main shut-off valve is, turning a minor leak into a major flood before the plumber arrives.
