Is your central heating system dropping pressure? You might have a hidden leak!

Pressurised Pipe Survey

Ideal for damp properties or anyone who suspects they have a leak but aren’t sure.

Think you have a leak?

We offer a pressurised pipe survey by a gas safe engineer. This isn’t a full leak detection survey but it is:

  • Ideal for properties that have had a damp survey and leaking pipes are suspected.
  • Ideal for properties where there is a suspected leak but no further evidence.
  • Ideal as a starting point for a full leak detection survey.
  • More cost effective than a full survey.

What we will do

The engineer will test all the pressurised pipework. This includes your heating system, hot pipework, main cold pipework, external to internal mains pipework.

We will thermal image and take moisture readings of the ground floor. The tests will take several hours and the engineer will start at 9am. The engineers are only booked for 1 job per day so they will methodically go through the process building up the evidence without being in a rush to be anywhere else.

Next steps

Should the results of the pipe survey conclusively show there is a measurable leak on the system then with your agreement the testing will move on to a full leak survey.

If however after the pressurised pipe survey there doesn’t appear to be a leak on the system the engineer will still produce a report with their conclusions which will hopefully stand you in good stead to get your issue fixed, whether it be an ingress of water from a window or evidence of rising damp.

From the first phone call to the last and throughout the entire visit the level of customer service was excellent. It was a relief to have a technician with so much experience and expertise attend the house to find our mysterious leak. Will definitely call-on again if and when we experience any more problems.

Harmuns really led the way on a 10-bedroom property that had bamboozled other firms. Despite the complexity, they clearly and concisely worked out what was wrong and planned out a successful course of action. They are our go to when we need specialist leak detection.

We found Harmuns on line and were so glad we did. We had a suspected leak under the tiles in our hallway/kitchen floor. The team were friendly and efficient; the issue was investigated thoroughly, located and repaired promptly. Highly recommend this company.

I was very impressed with the end to end customer service of this job. From the fast and attentive service from David initially to discuss the work and then Pete’s diligent hard work across 1 and a half days to identify and then fix the leak. Pete was respectful of our working from home and facilitated conversations when it was convenient to do so. He explained his findings every step of the way and tidied up well after the work was completed. I hope never to need their services again (!) but I can at least have the confidence that if we get a leak in the future we are in excellent hands.

I couldn’t recommend Harmuns more highly. We had damp issue which pointed towards a burst or leaking pipe and we engaged Harmuns to carry out a water leak survey and possible fix. Stephen the engineer who carried out our trace and access investigation could not have been more thorough; he went above and beyond to find the cause of our issue. From start to finish Harmuns team were friendly, professional and extremely knowledgeable. We will be using them for any similar issues going forward.

Excellent service. The engineer was prompt and thorough and was very reassuring. He located the leak and was able to access and fix it with the very minimum of damage, leaving the house clean and tidy and advising us how to dry the affected area. He checked the heating system was working properly and there were no further leaks before leaving.
