Plumbing leaks come in a variety of shapes and sizes. When most homeowners think of plumbing leaks, they think of big problems like burst pipes that send water gushing into the space around the sudden fault.

Causes of a Hidden Leak
There are many reasons your piping systems could suffer from a hidden leak, and some are easier to prevent so long as you maintain your pipes. Others can only be repaired with the help of a professional plumber. No matter the type of leak, the problem could cause terrible damage to your house and yard if it isn’t addressed quickly, so it is important to locate and address leaks as soon as possible.
Some of the most common causes of leaks include:
- Drains that have become clogged as a result of tossing inorganic or non-water-soluble items down the drain
- Pipes that have shifted due to earthquakes, mudslides, and other natural catastrophes
- Pipes that have been infiltrated or ruptured by twisting tree roots

- Unexplained increase in your water bill
- Damp spots on walls, ceilings, or floors
- Musty odors indicating possible mold growth
- Sounds of running water when no faucets are on
- Low water pressure
If you notice any of these signs, our skilled plumbers can pinpoint the issue before it causes significant damage.
