Trusted Commercial Plumbing Services in Longview, WA

Commercial Water Heaters and Boilers in Longview, WA

Commercial kitchens, gyms and multi-family buildings need large amounts of hot water. We service and install high-input tank water heaters, tankless racks and boiler-fed systems with storage tanks. Municipal water west of the mountains in Washington is generally soft, while supplies on the drier east side tend to run harder. Mineral scale can build up in these systems quickly, so we offer descaling and flushing on a schedule. We also install mixing valves to deliver safe temperatures at hand-washing sinks.

Commercial Restroom Fixture Service in Longview, WA

Maintaining functional and hygienic restrooms is vital for any commercial establishment in Longview, WA. FHN Plumbing provides comprehensive services for commercial restroom fixtures, including repair and replacement of toilets, urinals, sinks, and automatic faucets. We address common problems like persistent leaks, clogs, and low water pressure, making sure your commercial restrooms are always in excellent working order for your patrons and employees.

Slab Leak Detection & Repair for Businesses in Longview

Slab leaks can be especially damaging for commercial buildings, especially those built on concrete slab foundations. Glacial till and dense hardpan are common in western Washington, and they drain poorly enough to keep water against foundations and in crawlspaces. These leaks, often caused by shifting soil or corrosive water, can undermine foundations, lead to mold growth, and cause serious water waste. Our technicians use modern acoustic and thermal imaging equipment to pinpoint slab leaks without invasive demolition. Once located, we provide practical repair solutions, often involving re-routing or pipe repair, to protect your commercial property and prevent costly structural damage in Longview.

Commercial Drain Cleaning in Longview

FHN Plumbing offers specialized commercial drain cleaning services to keep your business's plumbing flowing smoothly. We use industrial-grade equipment like hydro-jetting machines, which use high-pressure water to scour the inside of pipes, thoroughly removing grease, food waste, and other common commercial blockages. This method is far more effective than traditional snaking for large-diameter commercial lines and ensures a thorough clean, preventing recurring clogs that can disrupt your operations in Longview.
