What to Expect From Our Plumbing Services in Montclair

Leak Detection & Repair

Leak Detection & Repair

Water leaks aren’t always obvious. Hidden behind walls, beneath concrete slabs, or under flooring, they can lead to mold, structural damage, and sky-high water bills. We specialize in fast, non-invasive leak detection using acoustic and pressure-based tools to locate the problem without tearing your home apart. Once located, we repair leaks with precision, ensuring it won’t return.

Clog Removal

Drain Cleaning & Clog Removal

If your sinks, tubs, or floor drains are backing up, our drain specialists can help. We remove blockages caused by grease, hair, roots, or foreign objects using powerful augers and eco-friendly methods. Regular drain cleaning also helps prevent future backups and protects your main sewer line from long-term damage.

Fixture Repair

Weak water pressure can point to sediment buildup, partially closed valves, or underlying pipe issues. We inspect the full system to identify the culprit and restore strong, steady flow throughout your home—so you can enjoy better showers, cleaner dishes, and faster fills.

Our full-home plumbing inspections are ideal for Montclair home buyers, sellers, and investors. We check for leaks, corrosion, low pressure, water quality concerns, and outdated systems. You’ll receive a clear report outlining issues, timelines, and recommendations—backed by our honest advice.
