We have used Guy plumbing for over 20 years and have never been disappointed. Always courteous, timely and competent. Re the last two visits, the first was about finding a lost wedding ring in the sewer pipe. On my finger now. A week ago Dan Cisneros managed to replace two our under mounted and cracked sinks without in any way disturbing the bathroom cabinets that contained them. All looks like new. I thought that was impossible — genius!

FAQ

How do I know if I have a hidden water leak?

Watch for unexplained spikes in your water bill, the sound of running water when everything is off, musty odors, or damp spots on floors, walls, or ceilings.

What should I do if a pipe bursts?

Shut off the main water valve immediately, turn off electricity to any affected areas, and call a plumber. Mop up standing water to limit damage while you wait.

Should I repair or replace my water heater?

If it’s leaking from the tank it cannot be repaired. If the parts are out of warranty, or repair costs approach half the price of a new unit, then replacement is usually the better value.

What's the best way to unclog a slow drain?

Start with a plunger or a hand auger (drain snake). Avoid chemical drain cleaners, which can damage older pipes and aren’t ideal for septic systems.

What causes low water pressure throughout the house?

Common causes include mineral buildup in pipes, a partially closed main valve, a failing pressure regulator, or a leak somewhere in the system.

Is a tankless water heater worth the higher upfront cost?

For many households, yes — the energy savings, longer lifespan, and endless hot water can offset the higher installation cost over time, especially with consistent hot water demand.
