Water damage on construction sites

Water damage is the second most frequent cause of loss during building projects

Water damage represents a large percentage of Construction All Risk (CAR) claims. Water damage occurs in large and small projects alike and it can bring an entire construction project to a halt.

It can ruin interiors, spur the growth of mould and damage electrical equipment. It can result in construction delays as affected areas dry out and damaged materials are discarded and replaced. It can reduce profit and add significant delays to completion schedules through clean up and replacement times.

The contractor will pay at least some of the costs out of their own pocket in the form of deductibles, debris removal costs that exceed the insurance coverage, and income lost due to delays even when insurance applies to the loss. Preventing water damage claims adds to a contractors bottom line.

With a focus on reducing construction defects, most water losses are preventable. Preventing water damage is critical to a construction business owner, even if insurance is in place. Losses can include property damage, debris removal, re-work and delay costs, not to mention the damage to reputation.

It generally costs very little to prevent water damage and primarily requires a focus on quality, planning and testing throughout the construction process.
