Homebuyer Pipe Survey

Peace of mind for homebuyers

Who is it for?

People generally agree a price for a property, possibly with the assumption that everything in the new house will work.

Swift assurance is given by a standard homeowner’s report. A surveyor will physically and visually inspect the property, the walls are standing and will take readings and give obvious recommendations. But to an extent many people blindly put their faith in hoping for the best and assuming that nothing further bad will emerge.

However, ask around your friends and family and someone will likely have a horror story about the house they bought and the series of unforeseen events that cost a lot of money, time and effort to put right.  And more often than not, all happening at a time when people may have pushed themselves to the maximum to get that dream home. So, what will we do for you?

What will we do?

  1. Test all hot and cold pipework.
  2. Test all heating pipework.
  3. Inspect visually all surface pipework / drainage / radiators (including in, below and around basins / toilets).​
  4. Pressure test underfloor heating.
  5. Check cylinder for age and condition.
  6. Check water tanks in loft, pipework and lagging for age and condition.
  7. Fire up the heating system and check it to be working.
  8. Fire up the radiators and check them to be working.
  9. Take thermal imaging of radiators to check for cold spots, poor performance and sludge.
  10. Take thermal imaging of underfloor heating to check pipe runs and performance.
  11. Take moisture readings on walls and floors.
  12. Take samples of heating water to check for quality.

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.
