California Consultants functions as an objective expert witness, analyzing building data to deliver an expert opinion that presents the client’s case in the most favorable terms.

Our firm is recognized as an expert in the industry for the entire building envelope from the basement to the roof. It is estimated that on any large project, waterproofing and drainage is often less than 5% of the total job cost. However, over 95% of project litigation is related to Water Intrusion.

We have consulted attorneys on matters that include basement waterproofing and drainage, sub-slab vapor barriers, podium slab and planters, building wrap/paper, sealants, exterior envelope systems (including doors and windows), roofing and insulation systems.

Our experts offer litigation support for ALL aspects and phases of the construction process for both commercial buildings and single family homes (not just waterproofing support).  Contact us today for a consultation.
