Foundation, Basement or Crawlspace Waterproofing and Encapsulation Companies in Mill Valley, CA

"I am incredibly pleased with this company. The entire crew were 100% professional. The owner of the company took time to answer my homeowner questions as they came up. He was very patient and thorough. All the men on the job worked incredibly hard and stayed on task throughout the project. They installed the French drain, installed a washout and removed an old deck all in a weekend. I would most certainly recommend them."

"Great team ang excellent work"

"I cannot say enough about how good this experience with John Mountain/Mountain Engineering has been. They said it would be 3 weeks; anti was. The work was painstakingly done, including a French drain behind the wall. And they replaced the plants that were destroyed during the process, which was an unexpected bonus."

"Very communicative, responsible and I had a great customer service experience with him. He really listens to the customer. He listened to my questions and inquiries and was able to provide answers and solutions."

"The team was amazing! We had an old deck in our backyard and we hired Palm Construction to replace and extend it and they did a great work! The job was done in less than 2 weeks, Communication was great, they cared about the backyard and plants and we are so happy itâ s all ready just before summer. Highly recommended!!"

"We’re absolutely thrilled with the work Tom and his team did on our backyard in Oakland! They transformed the space by installing grass, a sprinkler system, a flagstone area, a pergola, and a fence, while also addressing drainage issues to ensure the yard stays in great shape for years to come. Tom was reliable, responsive, and a true professional. From our first consultation, he listened to our vision, offered thoughtful suggestions, and kept us informed every step of the way. His communication made the entire process seamless and stress-free. The crew was fantastic—punctual, respectful, and hardworking. They showed up on time every day, worked efficiently, and left the site spotless. Thanks to Tom and his team, our backyard is now a stunning, functional space that we love. We couldn’t recommend Tomservice more highly!"
