Waterproofing service in Southlake, TX

The service life of a balcony waterproofing membrane depends on the product type, the quality of the original installation, and how much sun and foot traffic the deck receives. In North Texas, where summer temperatures regularly push into the triple digits, membranes on south- and west-facing balconies degrade faster than those in shaded locations. A membrane that was installed without proper termination details at the perimeter and at penetrations will fail earlier regardless of product quality, because water finds the edges first.

The answer depends on how much of the wall is affected and whether the underlying waterproofing layer is still intact. Isolated chips and cracks from hail impact can often be patched if the surrounding stucco is still well-bonded and the drainage plane behind it is undamaged. When hail has cracked a large portion of the finish coat or when water has already reached the substrate, a full replacement that includes a new drainage plane and air barrier is the more reliable long-term solution. An inspection of the full wall assembly, not just the surface, is the right starting point.

A thorough estimate should identify every area of the exterior where water can enter: window and door flashing, balcony deck membranes, roof-to-wall transitions, penetrations for utilities, and the condition of existing caulking and sealants. It should specify the products to be used, the sequence of installation, and how each transition will be detailed. An estimate that only lists a square footage price for a coating without addressing the penetrations and transitions is not accounting for the locations where failures actually occur.
