Maintain Your Plumbing Fixtures and Faucets

The best way to maintain your plumbing system is to call our expert plumbers the moment you notice a problem.

Call us when a leak first occurs so the problem doesn’t get bigger. Leaky faucets and running toilets cost you money, wasting water and costing you higher sewer taxes based on the greater water usage. You should also look for signs of a hidden leak, such as:

  • Low water pressure
  • High utilities bills
  • The sound of rushing water
  • Moisture around the home
  • Mold and mildew

We offer water leak detection services as well, so that we can hone in on leaks. If the leak is underneath your concrete foundation, we can provide slab leak detection and repair services. We can even use trenchless technology to repair your pipes.

Choose Our Dependable Company

We have been in business since 1912. We are licensed master plumbers and we are available when you need us. If the water pressure is low in your kitchen plumbing, you are installing a new dishwasher, or you need new water lines, you can call us. We also install commercial plumbing such as grease interceptors.

Call us for same day emergency plumbing repair or installation and maintenance appointments for residential and commercial properties. Call Max Sr. & Paul Schoenwalder Plumbing Heating Air Conditioning, serving the township of Union and the surrounding areas.
