Frequently Asked Questions

What is involved in your plumbing inspection?

Our comprehensive plumbing inspection is a proactive check of your entire system. For Matawan residents, this includes evaluating water pressure, checking for leaks at fixtures and connections, assessing water heater performance, and inspecting exposed pipes for corrosion—common in our area's older homes. Our licensed Master Plumber provides a clear report with any findings and practical recommendations to prevent costly emergencies.

How do you address toilet seal leaks, a common issue here?

Toilet seal leaks, often caused by worn wax rings, are a frequent issue in Matawan homes. We start by confirming the leak source, as water can travel along flooring. Our repair involves removing the toilet, thoroughly cleaning the area, and installing a new, high-quality wax or rubber seal. We also check the flange and toilet bolts to ensure a complete, watertight seal that prevents damage to your subfloor.

Are you licensed for both residential and commercial work?

Yes, absolutely. We hold a New Jersey Master Plumber license (#36B1007053), a Master HVACR license, and a Home Improvement Contractor registration. This full licensing allows us to handle any project, from fixing a residential kitchen sink to servicing complex plumbing and heating systems in local Matawan businesses. Our team has the expertise to meet the specific codes and demands of both settings.
