When something goes wrong with your plumbing in Seaside, you need a team that knows this community — not just the pipes. At Landmark Plumbing, we’ve been serving Seaside homeowners and businesses for over 25 years, and we understand the specific challenges that come with living this close to the coast. From the older residential neighborhoods near Broadway Avenue to the newer developments closer to Canyon Del Rey, our team is ready to respond quickly with honest, professional service every time.
Seaside’s coastal location means your plumbing system faces constant pressure from saltwater air, humidity, and the kind of accelerated corrosion that can quietly damage pipes, fixtures, and water lines long before you notice a problem. We use advanced acoustic leak detection and camera inspection technology to find issues early — minimizing damage to your property and keeping repair costs manageable. Our proactive approach is designed to give Seaside homeowners peace of mind before a small issue becomes a costly emergency.
As a family-owned, second-generation business, we treat every home in Seaside the way we’d treat our own. We never upsell unnecessary services, we explain exactly what we find and what your options are, and we back our work with warranties. Whether you’re dealing with a sudden burst pipe, a water heater that stopped working, or a slow drain that’s been ignored too long, our team is available 24 hours a day, 7 days a week — including holidays.

At Landmark Plumbing, we’ve built our reputation in Seaside the same way we’ve built it everywhere else in the Monterey Bay area — by showing up on time, doing the job right, and treating every customer like a neighbor. Our deep knowledge of the local housing stock, coastal conditions, and Seaside’s municipal plumbing codes means we can diagnose problems accurately and recommend the right solution the first time.
We’re a licensed and certified team with PHCS-trained plumbers on staff, certified in the latest piping systems including Aquaplex tubing, Flow Guard Gold, and Pro Press technology. For gas line work, we’re certified in Ward Flex, Track Pipe, Home Flex, and Polyurethane systems — so whether your Seaside home needs a routine repair or a full repipe, we have the training and tools to handle it properly.
Working with a locally owned plumbing company in Seaside means you get a team that’s genuinely invested in the community. We’re not a franchise or a call center — when you contact Landmark Plumbing, you’re talking to the people who will actually show up at your door. Honesty, integrity, and reliability guide everything we do, and we’re proud to have earned a five-star reputation with homeowners throughout Seaside and across the greater Monterey Bay area.
Our emergency plumbing services are available around the clock in Seaside, so whether you’re dealing with a burst pipe on a Sunday morning or a backed-up sewer line before the holidays, our team is ready to respond the same day. Seaside’s mix of mid-century homes, military housing conversions, and coastal properties means aging infrastructure is a common concern — and our plumbers know exactly what to look for.
For homeowners dealing with slow or blocked drains, our drain cleaning services include professional hydro-jet cleaning and camera inspections to clear the line and identify the root cause. If your issue is deeper in the sewer system, we offer trenchless sewer repair using Perma-Liner technology — a minimally invasive solution that protects your landscaping and hardscape while fully restoring sewer line function.
The coastal air in Seaside takes a toll on water lines over time. If your home has older copper or galvanized pipes, our piping and repiping services can upgrade your system using premium materials built to handle the Monterey Bay’s salt-heavy environment. We also offer water line repair and installation for both interior and exterior lines, and our certified technicians handle all gas line work safely and to code.
For those looking to improve water quality, we install and service water softener systems using ion exchange technology — an especially smart investment in Seaside where hard water buildup can shorten the life of your appliances and fixtures. And if your water heater is underperforming or failing entirely, our water heater services cover everything from conventional tank units to tankless, heat pump, and solar systems. We’re a preferred contractor for Bradford White, State Water Heaters, and Navien, so you know you’re getting quality equipment backed by expert installation.
Finally, our fixture repair services keep your faucets, sinks, toilets, and showers functioning reliably — whether you need a quick repair or a full replacement. Whatever your plumbing needs in Seaside, Landmark Plumbing is your trusted local team.
At Landmark Plumbing, our commitment to quality, honesty, and reliability is what has kept us serving Seaside and the greater Monterey Bay community for more than 25 years. As a second-generation, family-owned plumbing company, we bring more than just technical expertise to every job — we bring genuine care for the people and homes we work on. It’s simple: we treat every customer the way we’d want our own family treated.
We understand that letting someone into your home requires trust, and we take that seriously. Our plumbers are trained, certified, licensed, and background-checked. We communicate clearly, explain your options honestly, and never push services you don’t need. Every job we complete is backed by a warranty, because we stand behind our work long after we leave your driveway. Choosing Landmark Plumbing means choosing a team that values your long-term satisfaction above everything else.
The salt air along the Monterey Bay accelerates corrosion on exposed pipes, fixtures, and fittings. Homeowners in Seaside often see faster deterioration of copper and galvanized steel pipes compared to inland areas. Regular inspections and upgrading to corrosion-resistant materials like Aquaplex tubing or Flow Guard Gold can dramatically extend the life of your plumbing system.
Common signs include discolored water, a noticeable drop in water pressure, frequent leaks in multiple locations, or pipes that are 40+ years old. Many Seaside homes — particularly the mid-century and converted military housing stock in the area — are at the age where repiping becomes a smart investment. Our team can perform a full pipe inspection and give you an honest assessment of your system’s condition.
Call us at (831) 998-1787. We offer true 24/7 emergency plumbing service throughout Seaside and the greater Monterey Bay area. Our team responds quickly — many customers report arrival within 30 minutes — and we work to resolve the issue as efficiently as possible to minimize damage to your home.
Yes, hard water is common throughout the Monterey Bay region, including Seaside. Hard water causes mineral buildup in pipes and on fixtures, reduces appliance efficiency, and shortens the life of your water heater. A professionally installed water softener using ion exchange technology is one of the most effective solutions. Our team can assess your water quality and recommend the right system for your home’s size and usage.
Unexplained spikes in your water bill, the sound of running water when all fixtures are off, damp spots on walls or floors, and mold or mildew odors are all warning signs. We use advanced acoustic leak detection equipment that locates hidden leaks without tearing open walls or floors — protecting your property while finding the problem fast.
