Business overview

We use non-invasive methods to find any leak or source of water ingress within a property. We also provide a full repair and refurbishment service.

Our tradespeople are specialists at finding hidden or hard-to-find leaks in a property. They use high-tech detection methods that are non-invasive. It means they can pinpoint the location of a leak without causing damage.

This "trace and access" approach is favoured by insurance companies because it saves time and money.

We find leaks and sources of water ingress wherever they are in a property, including:

- Central heating systems (incl. underfloor heating systems)

- Underground mains water supply pipes

- Concealed internal plumbing (hot and cold water)

- Wastewater and soil water drainage pipes

- Roof coverings (pitched and flat roofs)

- Damp or rainwater entering via structural faults

A detailed report is provided as part of every investigation. This is usually vital when submitting a building or home contents insurance claim.

I could not agree more with most of the reviews, they take hours for a simple job to push up the bill, they are not competent and still have not solved the issue after many hours and 1600 to find a leak in a bathroom. When we complain they disappear and fail to communicate. Please avoid

ASPECT LEAK AND DAMP sent someone to fix a leak on 9th January at an agreed rate of £108 per hour. The leak was fixed but the bill was double what it should have been. It included more hours than they spent on site, included materials without identification and an item for £1000 called list price. We have not so far had any response from the company despite our efforts.

The only thing they are expert at is taking your money

Hopeless and clearly spinning things out in order to boost the bill. After four and a half hours he couldn't provide any more info about the location of the leak than I had given him and the start. At which point I told him to leave. Less than two hours later Aspect had taken a charge for £580 on my debit card, without my permission.
