Service Overview
What Is Patio Leak Detection?
Quick answer
Patio leak detection is the process of finding where water collects in or passes through a patio, through cracks, poor drainage, improper slope or failed waterproofing, and where it is reaching the house, such as the foundation or the interior wall next to the patio, so the right repair can stop water damage.
A patio is one of the most low-maintenance ways to enjoy time outdoors. It is easy to clean, comfortable and adds value to your home. But unless it is properly waterproofed and drained, a patio can leak like any other concrete or foundation structure.
Patio cracks collect debris and hold water over time. Left alone, those weak spots can eventually damage the whole patio or let water into your house, often showing up as dampness, staining or mold on the interior wall nearest the patio.
We locate where water is collecting and where it is getting in, explain what we find and tell you the total cost of any repair before repair work begins.

Symptoms & Causes
What Causes Patio Leaks?
- Uneven ground. Cracks tend to form when the ground beneath the concrete is uneven.
- Uneven water exposure. Sections of the patio that get much more water than the rest are more likely to crack.
- Improperly poured or finished concrete. Poor installation can lead to cracking over time.
- Poor drainage. A patio that does not drain properly becomes more susceptible to water damage.
- Incorrect depth. If a concrete patio is not poured at the proper depth relative to the house, it can direct water into the home’s foundation.
What the damage looks like
Signs of water damage include cracking, staining (often from mold growth, especially if the patio is enclosed and does not get much sunlight) and crumbling. It is normal for a patio to settle slightly over time, but excessive sinking is a sign that it is not draining well: the soil under the concrete stays wet for long periods and the slab settles.
Check inside, too
Check for moisture along the interior wall nearest the patio. Dampness, staining, mildew or mold there can mean patio water is reaching the foundation.
Tell us what you are seeing outside and in. We will explain how we would find where the water goes.

Detection Methods
Connecting Patio Water to Interior Damage
We test outside and measure inside so the repair targets the real path water is taking.
Water Testing
Controlled water applied to the patio, drains and house connection shows where water gets in.
Moisture Readings
Meters check interior walls, baseboards and floors next to the patio.
Thermal Imaging
Reveals moisture patterns along the foundation wall inside.
Line Testing
If water use is unexplained, pressure tests check buried lines under the patio.

Why It Matters
Why Patio Leaks Should Be Addressed Early
- Protect the foundation. Water directed toward the house can damage the foundation and the walls inside.
- Stop the spread. Small cracks grow as they collect debris and water, eventually damaging the whole patio.
- Prevent mold. Moisture reaching interior walls creates conditions for mold growth.
- Targeted repairs. Knowing whether the problem is drainage, cracking, slope or a buried line keeps repairs focused.

What are the signs of a patio leak?
Cracks, chips or flaking concrete (spalling), an uneven or sinking patio, pooling water, staining or mold, and dampness or mildew on the interior wall nearest the patio.
What causes a patio to crack?
Uneven ground beneath the concrete, sections that get much more water than others, improperly poured or finished concrete and poor drainage.
Is it normal for a patio to sink?
A little settling over time is normal. Excessive sinking suggests the soil under the concrete stays wet because the patio is not draining well.
Can a patio cause leaks in my house?
Yes. Poor drainage, cracks or a patio poured at the wrong depth relative to the house can direct water into the foundation and the interior wall next to the patio.
Could a pipe under my patio be leaking?
It can. If water use is unexplained or a wet area persists, buried supply lines under the patio can be pressure tested.
