Water penetration into interior spaces may result from errors in the design and/or construction of the wall drainage system.  In most cases, leaks can easily be avoided if the designer properly details the flashing and weep system and carefully monitors construction for quality workmanship and conformance with design.

Metal flashing is both a method and a key component for keeping water from entering a structure at roof penetrations, fenestrations, expansion joints and other interfaces within the building envelope. Flashings can be made of several kinds of materials, but the most flexible and durable are made of metal. Flashing is your last, best line of defense against the enemy of interiors, water.

It’s difficult to stop water infiltration in a building’s wall until the actual source is identified. A common method of tracing sources of water infiltration involves water testing, along with a review of original building drawings and targeted inspection openings.

Once the source(s) of water infiltration is determined, a plan for the design of the wall repairs can begin. Repairs can range from tuck-pointing to installation of properly designed through-wall and roof cap flashing systems. In severe cases, it may be necessary to reconstruct a portion of the distressed area.
