    The right company for the job
    Selina T.

    Mike is the BEST!!! He represents honesty, integrity and hard work. He and his team came out after another plumbing company gave me a bogus estimate and diagnosis they tried to get me to pay $5000 for work that did not need to be done. It was obvious an opportunity to deceive a homeowner that didn't know anything about plumbing. Mike not only fixed it but because of what he heard he gave it to me for free I'm so grateful to him. I highly recommend him and his team for any plumbing needs to do your homework. This is a reputable company.

    Tankless water heater installed!

    I called Matthew after a leak detection company found moisture readings under my bathroom tile. I…read morewas nervous about what they might find. Matthew came out promptly, assessed the shower, toilet area and surrounding space thoroughly and found no active moisture. Rather than recommending unnecessary work, he was completely honest about what he saw and didn't see. If you're looking for a plumber who tells you the truth even when it's not the easy answer -- Matthew is your guy. Rare find. Highly recommend! One tip -- Matthew is a one-man operation so give him a day or two to respond to calls. He's worth the wait!

    Matthew is an honest and well-mannered individual. He arrived on time with all the necessary…read moresupplies to complete the job. The work turned out to be more involved than he initially anticipated, but even when I offered to pay the difference, he stuck to his original proposal. Matthew took great care to protect our home, putting down floor coverings wherever he worked and thoroughly cleaning up afterward. He was especially careful when opening the drywall, only creating the openings necessary to complete the work properly, even when things got challenging. Since he was working on a gas line, he took extra precautions, checking for leaks three to four times. He was patient, thorough, and focused on doing the job right instead of rushing through it. Matthew also recommended a drywall professional to help close up the openings after the project, which was a huge help. Overall, I am extremely pleased with Matthew Plumbing. I would absolutely recommend him to others. His charges are reasonable, and he is responsible and communicative -- more than I could ask for.

    I spoke directly with the owner and tried to address a few service concerns I felt were not handled…read moreproperly. While he disagreed with my assessment, and was combative...my perspective didn't change... It only worsened in terms of the company... I'm the paying customer, and the experience didn't meet expectations... I deal with a lot of vendors across the state for my facilities so I know the difference between acceptable and unacceptable. My biggest issue was the lack of cleanup and how quickly the crew seemed ready to leave. My entire back patio was left covered in mud and debris. The mess extended to my pool (which required a separate cleaning), the side corridors, walkways, my new doors, and even my barbecue area... It was pretty nasty... The new barbecue just got put in so the white stucco is going to need to be repainted. The street in front of my home.. including both neighboring properties...was left with significant sludge and sentiment buildup. I ended up having to apologize to my neighbors and personally pressure wash the area myself. To be fair, I was told the pool might get dirty, but this was far beyond what I expected. They also backed up and blocked my pool overflow system, which had been working fine prior, and didn't address it before leaving. From my perspective, the crew seemed more focused on moving quickly toward cutting concrete and scheduling additional work rather than fully resolving the issue at hand... They were eager to get the initial job going which is fine, and said there are three guys ready to work, but unfortunately one guy probably should have been out on disability with what seemed like a broken arm. No disrespect, they all seemed nice from a personality standpoint... But when you're being billed per hour, you expect three healthy workers. I've had similar work done at my other properties, and this experience felt rushed and not up to a professional standard. What didn't sit well with me was the owner's lack of receptiveness to respectful, direct feedback... especially from another business owner. In summary: The issue was not resolved (roots were visible on camera but not cleared).. out 1300 bucks.. did you get a second opinion and a trenchless option with more appropriate tools was presented and being executed on. There appeared to be a push toward more invasive and costly work... And they couldn't really confirm where the actual blockage was. It was more of a guessing game. Cleanup was far below expectations I was left to handle the aftermath, including cleaning and neighbor impact This may not be everyone's experience, but it was mine. I'll let others decide accordingly.

Custom tile may be broken.. my wallet was sweating. Insert angelic music, a ray of golden sunlight, and a professional in blue overalls by the name of Chris. I took Chris to the war zone, and briefed him on what the other two plumbers said. In a dramatic Hollywood pause, Chris stared, grabbed his tools, and told me - "let me give it a try." In under an hour, Chris had not only defied the odds and proved the naysayers wrong - he did it with finesse! Chris epitomizes the essence of professionalism, grit, determination, and technical know how. Promote ahead of peers. 5 stars. Would definitely use again. THANK YOU, CHRIS!!

Matthew responded quickly to schedule an complimentary appointment with one of their plumber the next day. Joe was the person who came and he arrived on time. He first told me I could just do it myself and showed me what I had to do. I told him I needed a license plumber to do it per the home insurance requirements even though it's just replacing the bad unit with a newer one. He give me the price they charge and also other stuff I needed to do so everything continues to work properly. I appreciate his expert advice and time on coming out to give me an estimate. I thought the price just to switch out the bad unit with a new one was on the higher end so I decided to use another company.
