Frequently Asked Questions About Leak Detection

We know that having a leak is stressful and it is hard to think of all the questions you need to ask when you call…

These are some of the common questions we are asked every day…

Are you confident you can find my leak?2020-12-15T18:49:02+00:00

Yes, we are!

We are confident enough to have a ‘no find-no fee’* policy for most leak detection work we carry out.

This does not mean we avoid the hard jobs, and we have a broad range of equipment available and (unlike some of our competitors) each engineer carries all of this equipment to each job, including trace gas detection equipment, thermal imaging, acoustic detection and moisture mapping equipment.

Where leaks are not covered by our ‘no find-no fee’* policy, we do not just book works in where we feel that leak detection is either not viable, or prior works are recommended, such as power flushing a heating system.

* – ‘no find – no fee’ is offered for water leaks from water mains or hot/cold feeds within your home, it excludes heating leaks and multiple properties.

Please read T&C’s for full details.

You offer ‘no find-no fee’ leak detection, it sounds good….whats the catch?2020-12-15T18:48:09+00:00


We were fed up of seeing other companies poor quality leak detection works treat customers as cash cows, booking any old job in even when they knew it would be impossible. It gave the industry a bad reputation, so we decided to put our money where our mouth is!

We will test your property to its boundary and tell you what the issue is or we can prove you do not have an issue after a high water bill or water leak notice from your local water company.

There are things we do not cover as ‘no find-no fee’ such as damp and heating as there are too many variables…Obviously, it is not a free survey to ‘see’ if you have a leak, but from a known issue. All the T&C’s are available on our website in plain English, not written to confuse but more common sense.

We can prove if you do have a water leak when an insurer has tried to say it is damp and not an insured loss.

For clarity, we are inspecting a known issue for you. We cannot select just the tests to keep an inspection “free” and need access to all affected areas/properties.

Once a leak is located, our ‘no find – no fee’ policy is only active if we undertake the intrusive access works for internal leaks. Since we do not undertake external excavations, you are protected by our ‘No find – No fee’ for these leaks where applicable.

What tools do you use to find leaks?2020-12-15T18:47:01+00:00

Each piece of equipment adds to the overall survey, our surveyors carry a large range of equipment; this includes equipment to carry out:

  • Thermal Imaging
  • Acoustic Detection
  • Moisture Mapping
  • Trace Gas Detection
  • Chemical Analysis
  • Borescope

Importantly, we carry trace gas equipment to every job, something that some others do not do or want to charge more to use. The equipment we use is of the highest quality, and not all equipment is created equal!

Each job is different, and our surveyor will apply the correct equipment to your situation, we have other equipment specifically for other issues such as drain cameras and leak noise correlation.

There is lots more information on our technology pages with videos of how each works and is applied to finding you leak.

Will Leak Detection cause any damage?2020-12-15T18:44:16+00:00

The idea of modern leak detection is to locate a leak without causing any damage.

There are times where minor access is required to inspect or confirm an issue, this is normally a bath panel being removed, and in rare occasions (normally under shower trays) we might need to make a small hole the size of a pencil for a small camera to be inserted in voids and boxing.

It is important for making an insurance claim that minimal damage is caused as ‘speculative’ damage is not normally covered!

Will you need to turn the water off?2020-12-15T18:45:25+00:00

For heating leaks it is unlikely, but for all other leak detection, our engineer will likely need to turn off the water for a while.

When our engineer carries out pressure tests, we need the water off and for there to be no use of the water such as toilets, appliances etc.

Similarly, when we use trace gas, using water or having no access to switch off all stopcocks will release this trace gas and void the test.

It is important that the stopcocks are located and working, both inside and on the street where applicable.

This applies to all inspections whether domestic, commercial or civil building such as schools and inspections where the leak affects more than one dwelling.

How Long Does Leak Detection Take?2020-12-15T18:43:40+00:00

That really is the ‘how long is a piece of string’ question!

We would always ask that we have access for the full day.

Heating takes the longest on average; most visits take at least half a day, but there are times that an issue is found much sooner.

A hot/cold water leak will take about half a day to locate and provide a report on.

Sometimes what we think is ‘easy’ turns into a real head-scratching ‘hard’ leak and vice-versa.

Will it take more than one visit?2020-12-15T18:42:58+00:00

Leak detection is normally carried out on a single visit.

There are times where further visits are required, and these are chargeable at the same rate; however this is rare, and there is usually an underlying reason; Lack of access (particularly in flats) and blockages in heating systems are the normal issues. When undertaking insured works, there is normally an amount set for this of £5000 by the insurer, and they will cover unavoidable re-visits.

Once the leak is located, we offer intrusive access to the leak at the same cost as leak detection. Again this is covered if you have trace and access on your buildings insurance.

Once accessed, we recommend an independent plumber repair the leak to avoid issues with insurance and covering costs (such as the repair) classed as maintenance.

What is Secondary or Intrusive Access?2020-12-15T18:41:31+00:00

This is the destructive access of an area with a suspected leak and is carried out after our initial leak detection visit.

Leak Detection (trace) and these destructive works (access) are the parts normally refunded to you by the insurer under the “Trace & Access” portion of buildings insurance.

Access works mustn’t be jumped into until an assessment has been made for insurance cover. It is much better to deal with the insurer before you have large amounts of damage to repair!

Where minor access is needed, we may carry this out at the same time. Where another appointment is required, this is charged at the same rate as leak detection. A full report is also made for this visit to show how works have progressed and further helps with drying recommendations.

We must carry out the access works to keep the protection of our ‘No find – No fee’ policy.

Will you repair my leak?2020-12-15T18:40:35+00:00

In general we do not carry out repairs as standard, this is for a few reasons:

Insurance claims are 90% of our work and insurers will normally pay for the Trace (Leak Detection) and Access (Digging it up, or removing area). They will not pay for the repair, as this is maintenance. When the repair is simple (it is often a 50p fitting) the cost is in finding and getting to the leak, and the restoration works required.

If we repair, there is an element not covered by the insurer, they have in the past argued with our customers the ratio of repair costs and tried to deduct hundreds of pounds for a £20 repair. By not carrying out the permanent repair, this is avoided.

Also, there is a conflict of interest. Therefore if we are not carrying out the works, our recommendations are not just to produce work for ourselves…

While we are not plumbers, we will where possible make a temporary repair. We would recommend that you have a local plumber make a repair, as they can monitor any issues. We do have several plumbers we can recommend to you, but we think its best to have a local plumber when you can.

What is Trace and access?2020-12-15T18:39:42+00:00

Very simply, the cost of locating and accessing a leak, it is a vital part of ANY buildings insurance policy. If your policy does not have it, either add it or change insurers ASAP. The cover is normally £5000 of works or damage.

However, once an area is already water damaged the full policy covers this.

Will you repair the water damage too?2020-12-15T18:38:51+00:00

We are not builders, keeping our scope and skillset to leak detection.

Repairing will require drying machines, decorators, carpenters and often tilers and flooring specialists. In our experience, even builders struggle to quote to restore water damaged properties accurately.

In the case of an insurance claim being made, we recommend using a claims management company. They will carry out all of the required works and are paid directly by the insurer, the profit from this work, allows them the scope to deal with an often argumentative insurer and the hours spent on the phone to them!

In short, we are not builders, and you will require a certificate of dryness, and a host of other trades; something not in our scope of works.

How do I dry my Home after a leak?2020-12-15T18:36:31+00:00

You must get a certificate of dryness, normally drying machines will remove the moisture over a few weeks. Although the surface will dry quickly, there is moisture trapped deep in sub-floor areas that will cause mould and rot.

We recommend using a company that specializes in repairing water damage and dealing with insurance companies to handle your claim. You may well have your favourite builders, but dealing with insurers takes special skill…and the patience of a saint!

Drying is normally carried out with several industrial dehumidifier machines running to bring down the moisture levels. This is all covered under your insurance, even the electricity to run them!

How much does it cost?2020-12-15T18:35:55+00:00

If you have trace and access cover on your building insurance policy, then effectively it will cost you nothing!

Often there will be an excess of a few hundred pounds on most policies, but this is all it should cost to locate, access and restore the affected area.

However, any repairs to pipework are maintenance of your property, and you must pay for these to be carried out. However, with the cost of finding and getting to the leak covered, this is often a fitting costing about £1 and the labour to fit.

Due to repairs not being covered under insurance, we do not offer a repair service as it becomes a conflict of interest with the insurance claim. Better to have an independent plumber repair, a bit annoying but better than risking problems on the whole claim.

What about let properties or if I cannot be there?2020-12-15T18:35:17+00:00
Not a problem.
Ask for your leak detection invoice to be emailed over when you book with us and ensure adequate access is provided on the day.
What can stop you finding my leak?2020-12-15T18:33:05+00:00

Access to an area is a common problem, particularly in flats or shared mains; this causes 90% of the issues that can affect the inspection.

Blockages of heating systems from rust can cause issues that will require more works such as a power flush to get the system clean enough for leak detection to be carried out.

Ultimately given the access, we will get to the bottom of any leak…

Can you Find Boiler Faults?2020-12-15T18:31:32+00:00

Yes, in fact, boiler faults are responsible for about 20% of heating issues. Our detection methods allow us to test parts on-site that even the manufacturer’s service technicians cannot test properly without taking them away!

Obviously, we are looking for boiler faults causing leaks, and we are not able to diagnose electrical faults etc.

Can you help with making an insurance claim?2020-12-15T18:30:57+00:00


A great deal of care is needed to get a claim presented properly; sadly we find insurers are all too keen to stop a legitimate claim for whatever point they think they can apply, even when the cover is clearly in place and documented.

We work with several independent claims handling companies, who ensure the insurer does not give you a raw deal. They do not charge you but use the profit margin on the works to pay for the management of the claim.

Like all trades there are good and bad, we have found a number that consistently provides excellent service to our customers and can recommend.

These companies do not inflate the claim cost as there are chargeable rates for claims, so it will not make your premium any higher than dealing with the claim yourself. They make sure that all works, including drying your property, are carried out and have all the aggravation of the meetings and scores of calls to make to the insurer, loss adjuster etc.

Repairs after a water leak are complex, with specialist drying and certification, it is not just a builders job, and there are many trades to organise.

Your home is probably your greatest asset, and you cannot risk being stuck with the costs of repairing a £10,000 bathroom for a 20p pipe fitting failing!

Is there anything else to keep in mind?2020-12-15T18:28:28+00:00

With insurance, the initial call to them can be fine, but at this point, they have not had to pay anything; you are calling a basic call centre with little authority to make financial decisions.

Be careful of what you are being asked and make sure you have your documents to hand to check you have cover, rather than trust the call centre is being 100% accurate. They will be running several differently worded policies, and mistakes are often made at this point.

Plan for the worst and be pleasantly surprised rather than hope for the best and be disappointed.

Your property is likely your largest investment or asset, take advice and do not let the insurer dictate how this is managed!

What if I need to cancel of move appointment?2020-12-15T17:42:27+00:00

We understand that everything does not always go to plan and that at times you may need to cancel or move an appointment.

We are fair and adopt a system common across other sectors such as dentists, clinics and lessons/tutors in dealing with cancelling an appointment.

Unfortunately, we have had appointments where people have decided it is not convenient; this is not fair to ourselves or other customers who have had to wait for their appointment. Therefore, bookings cancelled or moved within 1 working day/24-hours will need to be subject to the full charge. For example, a Wednesday booking would need to be cancelled on Monday for no charge to be applied and a Monday booking cancelled on Thursday.

In short, there needs to be at least one working day between cancelling and the appointment date…

A booking made on the phone with our staff is in the diary and considered a formal booking and is not subject to any further confirmation.

We will endeavour to fill your cancelled or moved appointment, and in these cases, there would be no charge for the late cancellation.

Why not include the cost of accessing the leak?2020-12-15T17:41:21+00:00

We would need to charge a higher blanket rate to include access in a single visit. While convenient, this is unfair to those customers who ultimately do not need the access works carried out. This is part of ‘Trace and Access’ covered normally to £5000 of coverage, you will be refunded for these works and if using our claims management partners, can avoid all sorts of issues with making a claim.

Access works are more archaeology than just smashing our way through to the leak; they take time and care to locate properly and leave your home in a habitable state. Often scratching at the concrete and using a small brush until located is the main tool, with power tools used minimally.

Access works are not something we ‘want’ to do, it is a far harder and messier day’s work than leak detection; but we ‘should’ do it to close the claim off and provide the best service to you, our customers. It is also linked to our “no find – no fee” policy of carrying out access works.
