    TS Construction was by far the best experience I've had with construction projects. As long as they re in business, I won't be looking anywhere else.

    Great construction experience

    In 2014, we had a great experience using TS to remodel half of our house in Danville. The project was on budget, and was actually completed faster than anticipated. This year, we will remodel the other half of the house and will be using TS for this project as well.

    We had TS help us with a nearly complete remodel of a 1960s home in Pleasanton. Any large renovation will induce stress and anxiety. TS helped to decrease those worries and get the project done. I think it's easy to work with TS in order to facilitate your vision. The long ignored house that we purchased is now our beautiful home.
