Ceiling water leaks

A water leak inside of your home can cause significant damage to your property and possessions. Our leak tracing methods allow the fast detection of your leak with minimal disruption.

Water pipe moling

Water pipe moling is a highly effective method of installing underground pipes without the need for excavation, using remotely operated vehicle called a mole, which is guided through soil.

Central heating leaks

If your boiler is losing pressure, you could have a leak in your central heating system. We can fix leaks in your radiators, pipework and valves to keep your home warm in the winter.

Find your water leak early to keep costs low

Discovering a leak early is just the first step in keeping the cost of your repair as low as possible. It is essential that you locate the source of a leak immediately after first noticing reduced boiler pressure, an emergence of damp or an unusually high water bill.

The sooner you know what’s wrong, the faster it can be fixed. At Miracle Leak Detection, we use specialist equipment to identify areas of repair before it’s too late, saving you valuable time and money.

Remember, not all home insurance policies include Trace & Access cover, meaning that it’s up to you to find the leak before any repairs and compensation can be claimed.

Leak detection FAQs

If you’ve ever wondered what leak detection is, why it’s important, how it works, and even how much it costs, you’re in the right place.

We’ve put together some of the most common questions people ask us and have done our best to answer them in a clear and easy-to-understand way below.

So, whether you’re dealing with a leak in your home right now or are simply curious about the subject, we hope you’ll find these FAQs useful and informative.

What is leak detection?

Leak detection is the name given to the process of discovering if and where a leak has occurred within a system of water pipes or a property’s internal or external plumbing network. The process incorporates various methods and technologies, tailored to the nature of the suspected leak.

Why is water leak detection important?

Water leak detection is essential to prevent water wastage, property damage, and to maintain the integrity of your home’s plumbing system and pipework. Undetected water leaks can lead to structural damage, mould growth, and high water bills. It is important to act quickly when you suspect you have a leak.

How long has Miracle Leak Detection been in business?

At Miracle Leak Detection, we’ve been finding and fixing leaks for almost 10 years and our team has combined professional plumbing experience of over 30 years.

We are a fully registered and certified UK company with numerous five star reviews on Google, TrustPilot and Checkatrade. We understand how important it is to feel comfortable with any company you let into your home and pride ourselves on our friendly, fair and courteous approach to every job.

Are your technicians properly trained to detect and repair water leaks?

Yes. All of our technicians are highly trained in the specialist skills required for water leak detection. We are not a general plumbing company and, as such, we do not risk hiring staff that do not have the experience and attitude that our customers expect and the work demands.

We believe that our reviews are a good reflection of the high quality of work and service you can expect from our team.

Does the company have the latest equipment to detect and repair water leaks?

All of our expert leak technicians are equipped with the very best and latest equipment to help detect the source of your water leak.

From infrared sensors and pipe moling tools to replacement pipes and repair materials, we very rarely find ourselves in a situation where we can’t complete a job.

Our well established trade links mean we can order any necessary supplies to arrive within hours to ensure your leak is repaired in the shortest time possible.

How responsive is the company to customer enquiries?

We aim to respond to any enquiry as soon as possible, often immediately or within minutes of your initial contact. The most reliable way to get in touch is by calling us directly on 0800 037 7078, however replies to emails and contact forms may take slightly longer.

What device is used for leak detection?

Several devices are used for leak detection, depending on the unique circumstances of the leak at hand. Our methods include the use of acoustic sensors, infrared thermography and ultrasonic leak detectors. However, the most important tool we have is our experience and intuition. Our technicians are highly trained and are able to instinctively narrow down the general area of a leak for further inspection.

How does leak detection work?

Leak detection uses instruments that can sense changes associated with leaks, such as drops in water pressure, sound vibrations, temperature variations, or the presence of tracer gases. These changes are then analysed by a leak technician to determine the existence and location of a leak.

What is the benefit of leak detection?

Leak detection helps prevent damage and water wastage by identifying leaks early. It can save money by avoiding costly property repairs and high water bills, and can also prevent the emergence of potential health risks like mould growth.

How do you find an invisible water leak?

Hidden water leaks can be detected using specialised equipment such as infrared cameras, acoustic sensors, or moisture meters. These devices can identify changes in temperature, sound, or humidity that indicate a leak, even if it’s not visible to the naked eye.

Can a plumber detect a water leak?

Yes, a professional plumber can detect a water leak, however the existence of specialist leak detection companies shows just how difficult the process can be.

While a general plumber will be able to quickly fix a broken pipe, it’s unlikely they will have the specific tools and equipment required to trace a hidden water leak and access the affected area.

Leak detection is a highly skilled task and can have serious consequences for your property if not undertaken correctly.

Leak detection guides

Prevention is not only better than cure, it’s a lot less expensive! We’ve put together a selection of helpful guides to help you safeguard your home against unwelcome water leaks.

If it’s already too late and you already suspect you have a leak, we also provide advice about which steps to take next and when to speak to your water company. You can view our full range of leak detection advice guides here.
