    Kitchen remodel, master bathroom and closets

    We hired Platt Builders to remodel our kitchen and we are extremely happy with the results. Our experience was professional and thoughtful with the cabinetry details and the on-site installation was impeccable. When I had questions about the process and prices we were answered in a timely manner. We recently hired the Platt Builders team to remodel our master bathroom and closets. The experience was even more streamline this time as we are familiar with the team and process. We highly recommend Platt Builders!

    Major remodel
    $80,000

    We hired Platt to complete a major home remodel - they built a staircase, replaced all doors, flooring, exterior siding work, and a roof. The experience was one of the worst we have had with a contractor, and this is our third home and third major renovation.

    From the start of the project we had concerns. The project manager made clear to us that he was unhappy at Platt and it showed. He was often late and failed to respond in a timely way. We later learned that he was applying to other jobs and left Platt right after our job was complete.

    The workers sent by Platt to our home seemed unskilled. Nearly ever part of the work had to be redone - both minor (floors with large gaps, poor carpentry, painting issues), and major (roofing, water issues).

    We found significant safety issues with some of the work completed. Platt installed a metal cap on our clay lined chimney resulting in significant water leakage and potential carbon monoxide blockage and mold. When we raised this issue with Platt, instead of fixing it, they hired a law firm. It seems they have a pattern of failing to fix issues and instead using lawyers instead. Eventually they paid for some repairs to the chimney but only after we started to take legal action.

    We still have ongoing disputes with Platt about water leaking in another room, which we believe is due to how they applied the roofing materials, and poorly painted balusters. Instead of working with us, Platt again hired a law firm (curiously, they now have a new law firm).

    It's clear to us that Platt has become too big in recent years, and can't keep up the good work they might have done in the past. We've since used other contractors in the area who are excellent.
