"PCLA saved our property from serious foundation damage"

As a landlord, I was worried about foundation damage when my tenant reported water problems. PCLA's underground detection service found a serious leak under the driveway that could have caused major structural issues. Their professional repair work and complete restoration meant my tenant was happy, and my property investment was protected.

We had persistent soggy patches in our garden that wouldn't dry, even in summer. Other companies couldn't figure it out, but PCLA found the leak within a few hours. They fixed our mains water pipe with little fuss and restored our garden. The insurance was handled smoothly, and we've had no issues since.

Signs Your Property Needs Underground Leak Detection

Don’t wait until underground damage becomes a major disaster. Here are the warning signs that mean you need professional underground leak detection right now.

🚨 Soggy Ground That Won’t Dry Out

Persistent wet patches in your garden, especially during dry weather, often indicate underground pipe damage. This hidden water can cause serious foundation problems if left untreated.

Look out for:

Patches of ground that stay soggy even in dry weather;
Areas of your garden that are unusually green or lush;
Puddles forming with no obvious source;
Ground that feels soft or spongy underfoot.

🏠 Foundation Concerns and Structural Issues

Underground leaks can undermine your property’s foundations, causing expensive structural damage. Early detection protects your home’s value and your family’s safety.

Warning signs include:

Cracks appearing in walls or foundations;
Doors or windows that suddenly stick or won’t close properly;
New cracks in your driveway or pathways;
Settlement or movement in your property’s structure.

🚗 Driveway or Pathway Sinking

When underground water washes away supporting soil, driveways and pathways can sink or crack. This often indicates serious mains water problems that need immediate attention.

Check for:

Sections of driveway or pathway that have dropped;
New cracks appearing in concrete or tarmac surfaces;
Uneven surfaces where everything used to be level;
Areas that feel unstable when you walk on them.

💧 Water Pressure Problems Throughout Your Property

Sudden drops in water pressure can indicate underground leaks in your mains water supply. This affects your daily life and can signal expensive hidden damage.

Notice if:

Water pressure has dropped noticeably throughout your home;
Some taps have much lower pressure than others;
Your shower pressure has become poor;
Central heating system losing pressure frequently.

🌊 Garden Flooding with No Obvious Source

Water appearing in your garden during dry weather often means underground pipe damage. This can quickly escalate to serious property damage if not addressed.

Be concerned about:

Water pooling in areas of your garden;
Flooding that appears after you haven’t used water;
Wet areas that seem to have no connection to rainfall;
Standing water that won’t drain away naturally.

🧱 Persistent Damp Affecting Your Property

Underground leaks can cause rising damp and moisture problems inside your home. This creates health risks and expensive repair bills if left untreated.

Watch for:

Damp patches on internal walls, especially at ground level;
Musty smells that won’t go away;
Mould growth in unexpected areas;
Wallpaper or paint peeling near the ground.

Your Underground Leak Questions Answered

Let’s address your main concerns about underground leak detection. We understand you’re worried about damage to your property and want to know exactly what’s involved.

Will you dig up my entire garden to find the leak?

Absolutely not. Our acoustic leak correlation and thermal imaging equipment pinpoints the exact location of underground leaks before any digging begins. We locate the precise spot, then make only the smallest possible access hole for repair. Most of our customers are amazed at how little disruption there is to their garden.

How accurate is your underground leak detection?

Our state-of-the-art equipment is incredibly precise. We use acoustic listening devices that can hear water escaping from pipes underground, combined with thermal imaging that shows temperature changes from hidden water. This technology accurately locates leaks to within centimetres, not metres.

What happens to my driveway and landscaping?

We take great care to protect your property. Before any work begins, we photograph everything and plan the most efficient access route. If we need to access areas under driveways or landscaping, we restore everything to its original condition—that’s our guarantee to you.

How do you know exactly where to dig?

We never guess. Our leak detection engineers use multiple detection methods to confirm the exact location before any excavation. Acoustic equipment listens for the sound of escaping water, thermal imaging shows temperature variations, and ground-penetrating equipment maps your underground pipes. We only dig when we’re certain.

Does insurance cover underground leak detection and repairs?

Yes, most home insurance policies cover underground leak detection under trace and access provisions. We provide all the detailed reports, photographs, and technical documentation your insurance company needs. We’ve helped hundreds of Northern Ireland homeowners get their claims approved without hassle.

How long does underground leak detection take?

The detection process typically takes 2-4 hours, depending on your property size and the complexity of your underground pipe system. Repairs vary based on what we find, but we always give you a clear timeline before starting any work. Most underground leak repairs are completed within a day.
