How to Make a Successful Water Leak Insurance Claim

By Jim Flannery ACII, Brand Ambassador, OMC Claims. Over 40 years in insurance claims and a founding member of the Irish Claims Consultants Association.

A water leak rarely gives you time to prepare. One minute everything is fine, the next there is water coming through a ceiling and you are trying to think clearly while the damage spreads. What you do in those first hours has a surprising influence on how the claim turns out. If you would rather not face it alone, OMC Claims can have a loss assessor manage your claim from start to finish.

This guide takes you through the whole process, step by step, from the emergency actions on day one to the settlement at the end. It also covers the two parts people most often get wrong: the evidence they fail to capture early, and the value they leave on the table at the end.

The first 24 hours: a quick checklist

Before the detail, here is the short version of what to do straight away. The rest of the guide expands on each point.

• Make the area safe. Turn off power at the mains if water is near anything electrical.
• Stop the source. Turn off the water at the stopcock and the heating if relevant.
• Limit further damage, but only with temporary measures, not permanent repairs.
• Photograph and video everything before you clean up.
• Read the relevant sections of your policy.
• Notify your insurer or broker once the property is safe and recorded.
• Keep every receipt for emergency work and replacements.

Step 1: Make the property safe and stop the source

Safety comes before the claim. If water is anywhere near electrics, turn off the power at the mains before you go wading in, and turn off the gas as well if there is any risk to the supply. Turn off the water at the stopcock to stop more water entering, and switch off the heating system if that is the source of the leak. If you do not know where your stopcock is, now is the moment to find out, because every minute counts when water is flowing.

Once it is safe, do what you reasonably can to prevent further damage. This is not just sensible, it is a duty under most policies: you are expected to take reasonable steps to limit the loss. Move belongings clear of the water, catch drips, and lift soft furnishings off wet floors. One firm caution: take emergency steps only, not permanent repairs. Replacing a floor or re-plastering a ceiling before the insurer has seen the damage can undermine the claim, because the evidence of what happened is gone. Keep receipts for any emergency work such as a plumber or a drying company, as those costs are often recoverable as part of the claim.

Step 2: Document everything before you clean up

This is the step people most often rush, and the one that protects the claim more than any other. Once an area is dried and cleared, the evidence is gone for good. Before you tidy a single thing, record the scene properly. Think of it as building the file that will justify every euro of the claim later.

• Photos and video of the damage from wide angles and close up, including the source of the leak if you can see it. Video is useful because it captures context a still photo can miss.
• The water at its height if it is safe to record it, since the extent of standing water tells its own story about the scale of the event.
• Every affected item, with make, model and rough age where you can, plus any receipts, manuals or photographs you already have.
• Hidden and spreading damage, for example water tracking under floors, behind skirting, into adjoining rooms or down into the room below.
• A written report from a plumber or professional where you can get one, confirming the cause of the leak. Independent confirmation that the escape was sudden is valuable if the insurer later questions the cause.
• A simple written timeline: when you discovered it, what you did, who you contacted and when. Dates and times matter if the claim is ever questioned.

Strong evidence does two things. It speeds the claim up, because the insurer can see exactly what happened, and it makes it far harder for anyone to undervalue the loss later. If a claim is ever disputed, the homeowner with thorough records is in a far stronger position than the one relying on memory and a couple of blurry photos.

Step 3: Check what your policy covers

Before you phone your insurer, take ten minutes to read the relevant sections of your policy. You are looking for three things: whether the cause is likely to be treated as sudden or gradual, what your excess is, and whether you hold useful extras such as trace and access or alternative accommodation.

Our guide to what home insurance covers for water damage breaks down the covered and excluded categories, including the higher excess that often applies to escape of water. Knowing this before you speak to the insurer means you frame the claim accurately from the start, rather than saying something early that works against you.

Step 4: Notify your insurer promptly

Most policies require you to report a claim without unreasonable delay, so contact your insurer or broker as soon as the property is safe and documented. Give a clear, factual account of what happened and when. Be accurate and measured, and avoid speculating about the cause if you are not certain, because an off-the-cuff comment can be written down and treated as fact later.

Note down who you spoke to, the date and time, and what was agreed or requested. If the insurer appoints a loss adjuster to inspect the damage, it is worth being clear in your own mind about one thing: that adjuster works for the insurer, not for you. They are professional and often perfectly fair, but their job is to manage the claim from the insurer’s side.

Step 5: Prepare and value the claim

This is where claims are won or lost on value. A proper claim is built around a detailed schedule of loss: a room by room, item by item account of the damage and the realistic cost of putting it right. That includes the work that is easy to forget, such as drying out the structure, treating for mould, lifting and relaying floors, and reinstating finishes so they match across a room rather than leaving a patch.

Underclaiming is more common than people think, and it is rarely deliberate. Homeowners focus on the obvious damage and miss the hidden and consequential costs. A complete valuation reflects the true cost of full reinstatement, not just the parts you can see today. This is the stage where a well-prepared water damage insurance claim pulls clearly ahead of a rushed one.

Step 6: Negotiate the settlement

The first offer is not always the final figure. Once the insurer or their loss adjuster responds, the claim moves into negotiation. This is where experience counts, because it involves justifying the value of the loss with evidence, challenging anything that has been left out, and holding the line on what the policy actually owes.

If you are not confident doing that yourself, or you have already been offered a figure that feels low, it is worth getting advice before you accept anything. Once you sign off on a settlement, reopening it is difficult. We cover the errors that do the most damage at this stage in our guide to the common mistakes to avoid on a water damage claim.

How long does a water damage claim take?

There is no single answer, because it depends on the scale of the damage and how the claim is run. A straightforward escape of water with clear evidence can move quickly. A larger or disputed claim, with drying time, structural repairs and back and forth over value, takes longer. What consistently speeds things up is good evidence from day one and a complete, well-presented claim, because there is less for the insurer to query. What slows things down is a thin claim that has to be revisited, or a dispute over cause that could have been avoided with the right framing at the start.

What it costs, and when to appoint a loss assessor

You are never required to use a loss assessor, and for a small, straightforward claim you may be perfectly fine on your own. For anything significant, complex or already disputed, a loss assessor prepares and negotiates the claim on your behalf and works to make sure nothing is missed, undervalued or wrongly excluded.

On cost, a loss assessor’s fee is typically a percentage of the settlement, agreed with you in advance before any work begins. At OMC Claims that is usually 10% plus VAT, and some policies include cover towards professional claim preparation costs. The fairer way to weigh it is the overall outcome: a properly prepared and negotiated claim helps make sure nothing is left out, which is the reason appointing an assessor can be worthwhile even after the fee. OMC Claims acts only for policyholders, never for insurers, and is regulated by the Central Bank of Ireland.

Frequently asked questions

How do I make a water damage insurance claim?
Make the property safe and stop the source, document the damage before cleaning up, check your policy, notify your insurer promptly, then prepare and value the claim before agreeing any settlement.

Should I clean up before documenting water damage?
No. Record the damage with photos and video first. Once an area is cleaned and dried the evidence is lost, which can weaken the claim and make undervaluation easier.

How long do I have to report water damage to my insurer?
Most policies require you to report without unreasonable delay. Contact your insurer or broker as soon as the property is safe and you have recorded the damage.

What evidence do I need for a water damage claim?
Photos and video of the damage and its source, an inventory of affected items with age and value, any receipts, evidence of hidden damage, and a short written timeline of events.

Can I claim for a water leak on home insurance?
Usually, if the leak is sudden and accidental, such as a burst pipe or escape of water. Water damage from defective seals around baths and showers and damage from wear and tear are normally excluded.

How long does a water damage claim take to settle?
It varies with the scale of the damage and how the claim is run. Clear evidence and a complete, well-presented claim tend to speed things up, while thin or disputed claims take longer.

Will my premium go up after a water damage claim?
It can. A claim may affect your premium or no-claims-bonus position at renewal, which is one reason to check your excess and NCB to weigh up smaller claims carefully. The effect varies by insurer, so it is worth asking before you proceed.
