What Causes Leaks?
Leaks can stem from various sources and creep up when you least expect them, creating chaos in your home or business. Understanding common causes will help you spot signs early and prevent small issues from snowballing into major problems.
Here are some frequent culprits behind leaks:
- Aging pipes – Corroded or worn-out plumbing systems can quickly develop weak points.
- High water pressure – Excessive pressure stresses your pipes, leading to cracks or bursts.
- Poor installation – Faulty setups during construction or repairs can lead to recurring issues.
- Temperature changes – Frequent freezing and thawing can cause pipes to expand, contract, and eventually crack.
- Tree root intrusions – Roots searching for water can infiltrate underground pipes, causing blockages or leaks.
With Marines Service Co., you don’t have to guess where the problem lies. Our technicians use advanced tools to detect even the most elusive leaks and provide swift, efficient repairs. Trust us to protect your property and save you time, money, and frustration.

How We Find the Leaks You Can’t See
Some leaks are obvious. Others stay hidden behind walls, under floors, or in your foundation—causing damage long before you notice a spike in your water bill or a warped floorboard. Our licensed technicians at Marines Service Co. use specialized tools to locate leaks without unnecessary damage to your home.
We use a mix of advanced and time-tested methods to detect leaks accurately:
- Thermal imaging cameras reveal temperature changes caused by water behind walls or under flooring.
- Acoustic sensors pick up the sound of escaping water, even through concrete slabs.
- Video pipe inspections let us look inside your plumbing system using a small, flexible camera.
- Moisture meters measure humidity and water presence in drywall or flooring without tearing anything out.
Once we find the source, we’ll walk you through the problem and give you a straightforward, fixed-price repair option. No surprises, no pressure—just solid service you can count on.
Why Timely Leak Repair Matters
Waiting too long to address a leak can lead to a long list of problems that go far beyond water stains. Even a slow drip can silently damage framing, insulation, flooring, and drywall. The longer water sits undetected, the greater your risk of mold, mildew, and even pest problems.
Here’s what can happen if you delay leak repairs:
- Skyrocketing water bills
- Structural damage to your home
- Black mold growth
- Damage to flooring, cabinets, or drywall
- Pest infestations due to excess moisture
Leaks don’t resolve themselves—they just get worse. The sooner we can locate and repair the issue, the better off your home (and wallet) will be.
