Water where it should not be
A dripping faucet, wet cabinet, stained ceiling, damp wall, or unexplained puddle can be a sign of a plumbing leak. Finding the source early can help prevent a small leak from turning into a larger repair.

Tell Gress Plumbing what is going on and we will take it from there. We provide commercial and residential plumbing service throughout Simi Valley, handling everything from leaking fixtures, clogged drains, and water heater problems to sewer lines, piping, and larger plumbing repairs. Whether the issue is inside a home, rental property, office, or commercial building, we focus on finding the source of the problem and determining what needs to be done to correct it.
Every visit starts with a look at the actual problem before any work begins. We take the time to assess the affected plumbing, explain what we find, and go over the recommended repair or replacement with you before moving forward. Gress Plumbing provides flat-rate pricing quoted before we start, so you know the cost ahead of time rather than waiting until the work is finished to find out what you owe.
Symptoms
A dripping faucet, wet cabinet, stained ceiling, damp wall, or unexplained puddle can be a sign of a plumbing leak. Finding the source early can help prevent a small leak from turning into a larger repair.
If a sink, shower, toilet, or floor drain keeps slowing down or backing up after being cleared, there may be a larger problem farther down the line. Recurring drainage issues are worth having properly inspected rather than repeatedly treating the symptom.
