THE AFFORDABLE SPECALISTS, ALWAYS PROFESSIONAL ALWAYS NEAT, BECAUSE YOUR OPINION MATTERS. IN BUSINESS SINCE 1986. WE ARE FAMILY OWEND AND OPERATED, LICENCED AND BONDED, BEST PRICES (DO TO LESS OVERHEAD) WE WILL BEAT ANY WRITEN ESTIMATE. WHY PAY THOUSANDS MORE WHEN YOU CAN GET BETTER QUALITY OF WORK AT BETTER PRICES? WE ALSO OFFER THE BEST WARRANTIES ON WORK PERFORMED, WE SPECIALIZE IN COPPER REPIPES AND SEWER REPLACMENTS WITH TRENCHLESS TECHNOLOGY. WE DO IT ALL.

"I recently had a very disappointing experience with Restore Tactics. After a pipe burst in my home, the owner, James Duran, came to assess the situation. He immediately set up around eight air blowers and dehumidifiers and assured me he would guide me through the process of submitting a claim to my insurance company. However, the nightmare began when James assigned a supervisor, Robert Medina, to oversee my case. Since February 1, 2025, I have been left without a kitchen, and the entire process has been incredibly frustrating. Despite being paid for services that were never delivered, my attempts to reach James have been met with complete silence. Robert claims that my case is out of his hands, leaving me feeling abandoned and helpless. In hindsight, I wish I had done my research before choosing this company. I?ve since discovered that Restore Tactics has multiple lawsuits against them, including one involving a church. This raises serious concerns about their business practices "
