We purchased a home in 2020 that had undisclosed water infiltration in the basement that resulted in all basement finishes needing to be demolished to clean up the water and remove mold. TerrFirma was the only company who was able to diagnose and address both water infiltration caused by poor exterior yard grading and drainage and also the interior water proofing needed. They also repaired and stabilized a very large structural crack in our basement foundation wall. In addition to doing all this work they were also able to fit earthquake retrofitting into the project while here when asked (after they showed up to start the project). The estimator, Bridget was very meticulous in her bid and made comparing estimates easy. Her experitse, flexibility, follow through and communication were superb. Working with Spencer Hunt, the project foreman, was so stress free. He was able to accommodate our request for earthquake retrofitting even though TerraFirma was extremely busy. He was excellent at explaining everything the crew was doing. He checked in with us through every step of the process to make sure we were educated about and happy with the work. We are so happy we used TerraFirma and would recommend them to anyone who needs drainage, foundation, concrete, earthquake and waterproofing work done in the future!
