What should I do if my commercial building has an active leak?

An active leak in a commercial building requires prompt, informed action to limit potential damage and protect building occupants, assets, and structural components. Leaks can originate from a range of sources, including deteriorated roofing, failed sealants, damaged facade materials, or underlying waterproofing system issues. In the New England region, factors like frequent rain, freeze-thaw cycling, ice buildup, and salt exposure often accelerate building envelope vulnerabilities, making timely assessment essential.

First, address immediate safety concerns. If water presents a slip or electrical hazard, or is compromising sensitive equipment or structural members, restrict access to the affected area and consult internal safety protocols. Use temporary containment or diversion methods (such as buckets or absorbent barriers) to limit water migration, but avoid making intrusive repairs without professional guidance, as this can complicate later remediation.

Document visible leak points, staining, or damage, including photos and descriptions, to help guide the evaluation process. This information is valuable for commercial property owners, facility managers, and insurance claims, and will support the restoration contractor in isolating the source.

Schedule a professional inspection by a commercial waterproofing and building envelope specialist such as ESI Waterproofing & Masonry Restoration, Inc.. Complex structures, especially those in New England, often have hidden vulnerabilities in masonry, flashing, sealants, expansion joints, or concrete slabs that can allow water to travel far from the point of entry. A professional evaluation may involve moisture mapping, infrared scanning, and exterior condition surveys to accurately trace the leak and recommend repairs that address both the symptoms and underlying causes.

Long-term protection requires not just fixing the visible leak, but addressing contributing factors to prevent future intrusion. This may include upgrading sealants, repointing masonry, restoring facade elements, repairing expansion joints, or applying protective coatings. Preventative maintenance, such as regular inspections and timely repairs, is especially important in the New England climate, where seasonal changes can rapidly worsen small vulnerabilities.

Proper planning, repair execution, and adherence to industry best practices ensure that repairs provide lasting durability, preserve building value, and minimize operational disruption. Engage a process-oriented, regionally knowledgeable contractor with experience in complex leak detection and restoration for best results.
