Water damage on construction sites is a leading cause of loss in the construction industry, responsible for an estimated $16 billion in annual insurance payouts in the US and accounting for over a third of all construction liability losses. Yet for most general contractors, it remains one of the least systematically managed risks on any job.
That was the starting point for Wint CEO Alon Geva’s keynote introduction at The Risk to Resilience Summit, where he opened by putting the question directly to attendees: has your organization dealt with water damage on a job site?
The answers were telling.
What the Data Revealed
Before the first session began, attendees completed a short poll. The results painted a clear picture of where the construction industry stands on water risk today.
74% of respondents had either experienced water damage on a job site or had a near-miss where a leak was detected and brought under control before causing major damage.
76% of respondents either already have a formal construction water mitigation plan in place or are currently working on building one.
6 in 10 respondents had discussed water mitigation with their insurance provider in the past 12 months.
While awareness appears high, the industry’s loss experience suggests awareness alone isn’t reducing exposure. Claims severity continues to rise, and the cost of major water events is increasing faster than many contractors realize.
Why Water Damage on Construction Sites Is So Hard to Contain
Part of what makes water damage so persistent is that it tends to stay invisible until it becomes expensive. Leaks can spread behind walls, under slabs and across multiple units for hours or days before anyone notices. By the time the damage is visible, the cost is rarely limited to the repair itself. Delays, rework and the reputational impact on the GC all compound from there.
Nationwide’s construction claims data reinforces this: median water damage claim costs rose 21% year over year, and large losses exceeding $500,000 have doubled since 2015, with losses over $1 million tripling in the same period.
The industry has also been slow to move away from assumptions that no longer hold. Geva flagged two that come up repeatedly: the belief that visible damage is the only damage worth worrying about, and the belief that having insurance is a substitute for prevention.
“Many teams operate on the false assumption that we’ll know when something breaks, or that’s what we have insurance for,” he said. “And they lack implementation of their plans between shifts, overnight, on weekends, when no one is watching.”
Effective mitigation increasingly includes automated shutoff systems, real-time leak monitoring, documented inspection procedures and after-hours risk controls designed to catch issues before they escalate into major losses.
Having a construction water mitigation plan is a meaningful first step. Executing it consistently, across every shift and every stage of a project, is where most organizations fall short.
Insurers Are Raising the Bar
The pressure to close that gap is coming from the insurance market. Geva was direct about how the dynamic has shifted: insurers are increasingly looking for documented risk controls, incident tracking and site-level data that demonstrates water mitigation measures are actively being followed – not simply documented in a project manual.
For GCs who absorb the cost of delays and rework when damage occurs, that shift creates real financial exposure beyond the claim itself. And for those with ESG commitments, millions of gallons of water lost on a construction project creates accountability in a different column entirely.
“The expectation is to have it visible, actionable and accountable by all stakeholders,” Geva said.
The Gap Is Execution, Not Awareness
The most important framing Geva offered came at the close of his remarks. The tools for managing water damage on construction sites exist. The insurance incentives for doing so are real, and the consequences for teams that fall behind are already showing up in premiums and coverage terms. The data from job sites that have implemented these plans correctly shows, consistently, that it works.
“The gap isn’t awareness. It’s between thinking risk is managed and actually managing it in real time.”
The sessions that followed unpacked what closing that gap looks like in practice, including how insurers evaluate construction sites, what happens when a major water event plays out in real time, and how climate volatility is expanding exposure across the built environment.
The firms that move first, Geva argued, will carry lower risk, lower costs and stronger insurer relationships into every project that follows. In an industry where water damage remains one of the largest and most preventable sources of loss, the competitive advantage will increasingly belong to organizations that can manage risk in real time, rather than those that respond to it after the fact.
