Emergency Plumbing

A plumbing emergency includes burst pipes, sewer backups, major leaks, or any issue that can quickly cause water damage or create a health risk. These problems should be addressed immediately.

Response times vary, but in many cases a plumber can arrive within about one hour in Marin County depending on availability and location.

Shut off your main water valve as soon as possible. This helps prevent further damage. You can also use towels or containers to manage any leaking water.

Yes. Small leaks can quickly get worse and lead to structural damage, mold, or pipe failure if not addressed early.

We handle burst pipes, overflowing toilets, sewer backups, broken water lines, and sudden loss of water pressure in both residential and commercial properties.

Drain Cleaning

Recurring clogs are often caused by grease, soap buildup, hair, or debris that accumulates over time. In some cases, the issue may be deeper in the sewer line.

You can try using a plunger or flushing the drain with hot water and dish soap. Avoid chemical cleaners, as they can damage your pipes over time.

Most homes benefit from professional drain cleaning once a year. Older homes or heavy-use households may require more frequent service.

Call a plumber if clogs keep returning, multiple drains are affected, or water drains very slowly. These are signs of a larger issue.

Yes. Untreated clogs can lead to pipe damage, sewage backups, and potential health hazards if bacteria builds up in the system.

Trenchless Sewer Repair

Trenchless sewer repair is a modern method used to repair or replace underground pipes without digging up your yard, driveway, or landscaping.

The process typically involves inserting a new pipe liner or pulling a new pipe through the existing damaged pipe to restore proper flow.

In many cases it is faster, less disruptive, and more cost-effective because it avoids major excavation and property damage.

Signs include slow drains, sewage odors, gurgling sounds, and repeated clogs throughout your home.

Modern trenchless solutions are designed to last for decades when properly installed, providing a durable and reliable fix.

Residential Plumbing

Low water pressure can be caused by mineral buildup, leaks, pipe corrosion, or issues with your pressure regulator.

Leaky faucets are usually caused by worn washers or seals. While some minor repairs can be done at home, ongoing leaks should be handled by a professional.

A running toilet is typically caused by a worn flapper, faulty fill valve, or improper chain adjustment inside the tank.

Common signs include frequent leaks, low water pressure, discolored water, and older galvanized pipes, especially in older homes.

Look for inconsistent hot water, unusual noises, rust-colored water, or leaks around the unit. These may indicate the system is nearing the end of its lifespan.

Commercial Plumbing

Yes. Amesos Plumbing provides commercial plumbing services for businesses of all sizes, including repairs, system upgrades, and new installations.

In many cases, we can respond within about one hour. Fast response helps minimize downtime and prevent damage to your business.
