Pearl River Leak Detection and Repair

McNamara Heating & A/C Inc has over 30 years of plumbing experience, serving residential and commercial properties throughout the Pearl River area. We take a comprehensive approach to leak detection and repair, combining advanced diagnostics with hands-on knowledge to get to the root of the issue. 

Our plumbers are equipped to handle everything from routine drain cleaning to complex hidden leaks. We offer same-day scheduling as far as we can accommodate, and emergency services are available for those situations that just can’t wait. 

Call today at (845) 712-9728.

Non-Invasive Electronic Leak Detection 

Not all plumbing problems are visible, but tearing into walls or floors to find a leak isn’t always necessary. Our non-invasive electronic leak detection methods allow us to pinpoint the exact location of hidden leaks. 

By using specialized equipment, we can identify issues behind your walls, under your floors, or within your plumbing system without unnecessary disruption. 

Slab Leak Detection and Repair 

Homes with concrete slab foundations, common in many mid-century Pearl River builds, can be particularly vulnerable to hidden plumbing leaks beneath the surface. Left unaddressed, slab leaks can lead to structural concerns, rising utility bills, and moisture-related issues. 

Our team works diligently to identify the precise source of the problem and recommend efficient solutions. 

The Costs of Hidden Water Leaks

Even a minor 'silent' leak can result in hundreds of dollars in unnecessary utility charges each month. We work closely with local homeowners to investigate high-bill alerts from municipal water departments, using acoustic equipment to find leaks that often go unnoticed in older Hudson Valley plumbing systems. 

By identifying these hidden spikes early, we aim to help you avoid the high costs associated with local water waste while protecting the integrity of the aging infrastructure common to our community.
