5 star experience for a hard to locate source of leak

Very happy with how everything was dealt with! We had a leak, googled and called ADI and they booked us for next day.

Robert was sent to our property and he was very professional, knowledgeable, polite & worked with a high level of care without causing unnecessary damage.

I would give 5 stars to the office people and a separate 5 stars to Robert for his efforts to thoroughly investigate and fix the issue.

Excellent service from start to finish.

Excellent service from start to finish.

The engineer Grant who visited my premises outlined step by step what checks he would be doing and with what equipment.

He quickly identified the cause of my leak and fixed it.

Grant also kindly ran through suggestions and recommendations of what may prevent future issues.

If only all repairs were like this

This is one of the best experiences we have had.

In difficult circumstances they detected our leak, repaired it and helped us successfully make our insurance claim.

At all levels they were highly professional.

Communication was great and we received a speedy response to any queries.

It is not always like this but thank you to ADI Pro Leak.

Professional and Thorough

It was a stressful time as we had significant water damage to our new home which was caused by the plumber.

Chose ADI to come and detect and fix leak.

Frank was brilliant, he explained everything he was doing and what he found.

He also fixed the leak and was very efficient and tidy.

It wasn't a cheap service and we now have to battle with our plumber to get compensation but it was worth doing and the thorough report will help our claim.
