Commercial plumbing built around your business

At American Made Plumbing, our licensed team handles commercial plumbing for light to mid-sized properties, from restaurants and senior living facilities to office buildings and retail stores. The work covers routine maintenance, commercial plumbing repair, and new plumbing installations. We work closely with each client to fit the job around their operation, including off-hours service times or custom walkways so staff and customers can get past the work area.

Commercial plumbing FAQ
- What types of businesses do you serve?
- We serve restaurants, senior living facilities, office buildings, retail stores, and many other commercial properties. Our work focuses on light to mid-sized commercial properties. Property managers with several addresses are also part of the work we do. The same licensed team handles repairs, maintenance, and installations for all of them.
- How quickly can you respond to a commercial plumbing emergency?
- Commercial plumbing emergencies are handled as promptly as possible, and emergency service is available 24/7. For an urgent issue, call us directly so the right help can be arranged. Same-day visits are possible depending on that day’s schedule. Our trucks are stocked to finish most repairs on the first visit.
- What are the benefits of routine plumbing maintenance for my business?
- Routine plumbing maintenance prevents costly breakdowns, improves system efficiency, and helps identify potential issues early. A plumbing failure can close a restroom, shut down a kitchen, or keep customers away, so avoiding one protects the business as well as the building. Scheduled care also keeps pipes, drains, and water heaters in good shape for longer. We can set up maintenance around your operating hours.
- Can you work after hours to minimize business disruption?
- Yes, we offer flexible scheduling, including off-hours service, to reduce disruption to your business. When a business cannot close for a repair, the work can be planned outside opening hours. We can also set up custom walkways so staff and customers can get past the work area. You are kept informed at each stage of the project.
- How often should my business schedule drain cleaning?
- We recommend drain cleaning every 6 to 12 months for most businesses. The right interval depends on the nature of your business and how heavily the drains are used. Restaurants and other kitchens that send grease down the drains usually need cleaning at the shorter end. Regular cleaning prevents clogs and keeps the plumbing working well.
- Do you offer commercial water heater repair and replacement?
- Yes, we handle water heater repairs, replacements, and installations for commercial properties. A business that relies on hot water for a kitchen, restrooms, or residents needs the unit working reliably. We diagnose the problem and explain whether a repair or a replacement makes more sense. The work is priced before it starts.
- What are common signs that my business needs pipe repair?
- Low water pressure, frequent leaks, rust-colored water, and visible corrosion on the pipes are common signs that a business needs pipe repair. These problems are especially common in aging pipes in commercial buildings. Left alone, a small leak can grow into water damage that disrupts the business. A licensed plumber finds the cause and resolves the leak, damage, or aging pipe.
- Can you help with plumbing installations for business renovations?
- Yes, we install plumbing during renovations and remodels so your setup meets code requirements. That includes new fixtures and the supply and drain lines that serve them. We plan the work around your timeline and keep you informed at each stage. Our team holds a C36 plumbing contractor license and is insured.
- Do you offer maintenance packages for ongoing plumbing care?
- Yes, we offer maintenance packages customized to the needs of your business. A package can be built around how heavily your drains, water heaters, and fixtures are used. Regular visits help catch problems early and keep disruption low. Ask us what a package for your property would include.
