Why Your Property Value Plummets With Poor Drainage Health

The condition of a property's underground drainage system is often called a 'hidden property killer.'

For obvious reasons, damaged drains can lead to severe water damage, damp problems, mould and structural issues. All of these decrease property values and make selling property considerably more difficult.

But did you know…

Intelligent buyers have caught on. A thorough property survey will identify drainage problems every time. Once identified, buyers typically walk away or ask for large reductions on the selling price.

That is precisely why professional drain surveys for insurance companies and homeowners have become such an integral part of checking the health of underground drainage systems. The inspection uses CCTV technology to examine drains, piping and joints without digging up the garden. Instead, specialists are able to obtain a detailed look at what is happening below ground level.

Well-maintained drainage systems offer peace of mind to potential buyers, lenders, and insurers. Properties without them could have major problems lurking underground.

The Warning Signs All Homeowners Should Know

Diagnosing your drainage does not always come with rocks falling out of your toilets or your garden transforming into a swamp. Drainage problems usually show themselves in less dramatic ways.

Here are some of the most common drainage problems that could be affecting your property…

Keep an eye out for:

• Bathrooms and sinks that take ages to drain

• Persistent foul odours

• Damp patches on internal walls or floors

• Foundation cracking

• Areas of the garden which remain waterlogged

Slow drains, smells and patches of damp could all indicate an issue with your underground drainage system. Ignore these warning signs for too long, and you'll find yourself looking at a hefty repair bill.

Many people assume drainage problems are insignificant. The trouble is small problems left alone can turn into hidden disasters underground. Something as simple as a tiny crack in a pipe can lead to ingress, blockages and complete pipe collapse.

Not only is that a repair bill you likely cannot afford. But it can also void your home insurance policy.

What An Underground Drainage Inspection Entails

Underground drainage system inspections aren't what you think.

Instead of paying someone to dig up your garden pathways and pots. Drainage specialists run a CCTV camera through your underground pipes and analyze everything they find.

Inspections look for:

• Cracks in pipes

• Blockages

• Evidence of root ingress

• Collapsed sections of drain

The process is non-invasive, fast, and extremely thorough.

Most underground inspections take two hours or less. And thanks to modern technology, there is no need to dig up your lawn.

One of the biggest benefits of understanding the state of your underground drains is knowing about problems before they become catastrophic. Drainage problems can get very nasty indeed.

If you're buying or selling property, CCTV drainage surveys should be next on your to-do list. They provide sellers with proof that their drains are in good condition, and they give buyers peace of mind. Lastly, they help avoid expensive surprises during the conveyancing process.

The Costly Consequences of Ignoring Drainage Problems

Few things will cause property prices to plummet faster than ignoring drainage problems.

The latest figures from the Association of British Insurers reveal insurance companies paid out a massive £585 million to UK homeowners for weather-related damage in 2024. Failures with drainage and water management were behind much of the damage.

Water ruins don't stop there either…

Analysis by Go.Compare revealed that escape of water incidents were responsible for almost one in three home insurance claims made in 2024. Water damage is officially the number one reason homeowners make an insurance claim.

Needless to say, ignoring drains is a risky gamble.

When left unchecked, drainage problems can lead to:

• Structural problems caused by foundation damage

• Mould and damp issues

• Flooded rooms

• Contaminated soil from sewage leakage

• Collapse enforcement sales

The last point is especially important. If you don't disclose drainage problems before selling your property, you could face legal action from the buyer down the line.

It doesn't take long for drains to turn from a minor inconvenience into a nightmare. That is why the cost of maintaining them should always be less than the price of repairs.

How To Safeguard Your Property Value

Just like your car needs MOTing or boiler servicing every year. Your property needs its drains checking too. Think of a drainage survey as your property's MOT test.

Here's how you can make sure your drains are kept in tip-top condition.

• Get them surveyed. You should have underground drains health checked every 2-3 years, or before selling/buying a property.

• Clear your gutters and external drains. Preventative maintenance will always save you money in the long run.

• Don't ignore warning signs. Treatment is always cheaper than repair.

• Keep all documentation. Providing proof of maintenance and repair can increase property value and give buyers peace of mind.

Maintaining your drains keeps the rest of your property in good health. Doing this will save you money on costly repair bills and stop nasty surprises appearing at the last minute.

Nobody wants their drain to collapse while selling a house. And no mortgage lender wants to see a drainage problem on a pre-buying survey.

Your underground drainage system plays a vital role in protecting your property. But for some reason, it's often the first thing to be neglected.

A poorly maintained drainage system causes water damage, flooding, structural issues and financial loss. The best way to prevent these disasters? Regular underground drainage system inspections.

Remember

• Neglected drains cause costly damage to property

• Drainage problems often reveal themselves through subtler tell-tale signs

• CCTV Drain surveys are fast, affordable, and effective.

• Water damage is responsible for 1 in 3 home insurance claims.

• Prevention is better than cure.

Don't wait for disaster to strike. Ensure your drains are healthy with a professional inspection. It could save you thousands and maintain the correct value of your property.
