Is Damp Covered by Home Insurance?

If you have damp in your home, checking your insurance policy is a natural first step. For most types of damp, the answer is no. Home insurance covers sudden, unexpected events. Damp is usually neither.

That said, the cause of the problem matters more than the symptom. This guide explains what insurers cover, when you might have a valid claim, and what to do if you are not covered.

What Home Insurance Does Not Cover

Standard buildings and contents insurance excludes damage caused by gradual deterioration. Most damp falls squarely into that category.

Rising damp is almost never covered. Insurers treat it as a maintenance issue. A failed or absent damp proof course is considered wear and tear, not an insurable event.

Penetrating damp from defective brickwork, failed pointing, or worn render is excluded for the same reason. These are maintenance defects that develop over time. Insurers expect homeowners to catch and address them before significant damage occurs.

Condensation is excluded across the board. It is treated as a ventilation and lifestyle issue, not something an insurer will pay to fix.

Pre-existing damp is not covered under any circumstances. If damp was present when you bought the property, whether identified in a survey or not, no insurer will meet the cost of treatment.

When Home Insurance Might Cover Damp

There are situations where damp-related damage can form part of a valid claim. They all share one feature: the damp was caused by a sudden, insured event rather than gradual deterioration.

Burst or leaking pipes. If a pipe bursts and water damages walls, floors, or ceilings, most buildings policies will cover the resulting damage. The leak must be sudden and accidental. A slow drip that went unnoticed for months will not qualify.

Storm damage. If a storm damages a roof or external wall and water enters the property as a result, the damp caused by that water will typically be covered as part of the storm damage claim. Report it promptly and document the damage before carrying out any repairs.

Appliance failure. A washing machine, dishwasher, or water tank that fails suddenly and causes water to penetrate walls or floors may be covered, depending on your policy wording.

Flooding. If your policy includes flood cover, damp resulting from a flood event may be claimable. Standard policies often exclude flooding, so check your specific cover carefully.

In all of these cases, your insurer will want evidence that the damp was caused by the specific event rather than a pre-existing problem. A professional surveyor’s report identifying the cause is often essential.

Subsidence and Damp

Subsidence is worth addressing separately. It is covered by most standard buildings insurance policies, and it sometimes appears alongside damp.

Subsidence is the downward movement of ground beneath a property. It can create cracks in walls that allow water ingress, and structural movement can affect drainage in ways that contribute to damp problems.

If subsidence and damp are occurring together, damp caused directly by subsidence-related structural damage may be covered as part of your subsidence claim. The two are assessed separately, though. An insurer will not cover unrelated or pre-existing damp simply because subsidence is also present.

If you suspect subsidence, report it to your insurer before carrying out any repairs. Acting without insurer approval can affect your claim.

What to Do If You Are Not Covered

For most homeowners with rising damp, penetrating damp, or condensation, insurance will not help. The cost of treatment falls to you. Here is how to approach it.

Get an accurate diagnosis first

Before spending anything, make sure you know what you are dealing with. Damp is frequently misdiagnosed, and the wrong treatment wastes money. A professional damp survey identifies the type, source, and extent of the problem and gives you a clear basis for any quote.

Get a written quote with a guarantee

Any reputable company should provide a written specification of works and a guarantee backed by insurance. Guarantee Protection Insurance means your cover remains valid even if the company ceases trading, and it should transfer to a new owner when you sell.

Consider finance

Kenwood offers finance options to spread the cost of works. Damp treatment is an investment in your property, and the cost should not be a reason to leave a problem untreated. Ask about finance when you book your survey.

Act now, not later. Damp does not improve on its own. Rising damp causes progressive damage to plaster, timber, and masonry. Penetrating damp left untreated can lead to wet rot or dry rot in structural timber. A problem that costs a few hundred pounds to treat today can cost several times that in twelve months.

Damp Proofing Insurance: What It Actually Means

Home insurance and damp proofing guarantees are two different things, and the distinction is worth understanding.

A quality damp proofing guarantee, such as Kenwood’s 20-year guarantee, is backed by Guarantee Protection Insurance. This is not your home insurance policy. It covers the specific treatment carried out on your property. If rising damp returns within the guarantee period, re-treatment is covered. The guarantee is transferable on sale, which matters to mortgage lenders when damp has been identified on a property.

When commissioning any damp proofing work, ask three questions: is the guarantee insured, what exactly does it cover, and does it transfer when the property is sold?

Frequently Asked Questions

Does home insurance cover rising damp?

No, in almost all cases. Rising damp is a maintenance issue in the eyes of most insurers. The cost of survey and treatment is the homeowner’s responsibility.

Can I make a damp insurance claim after a burst pipe?

Yes, if the damp was directly caused by the burst pipe. You will need evidence linking the two, and the damage must have been reported and addressed promptly. A surveyor’s report identifying the cause will support your claim.

What is damp proofing insurance?

It refers to Guarantee Protection Insurance, which backs the guarantee a reputable damp proofing company provides on its work. It keeps your guarantee valid if the company closes, and it can be transferred to a new owner on sale.

If your insurer will not cover the cost and you need a clear picture of what the work involves, Kenwood offers surveys across London and the South East, written quotes with a 20-year insured guarantee, and finance options to spread the cost.
