“Kelly Williams and crew did a fantastic job on our bathroom remodel! We have been using Kelly Williams Plumbing services for years and they never disappoint. Professional and efficient!”

“They came to unstop a small sink during business hours. The two men were here less than thirty minutes (one watching/one working) and easily unstopped my sink. Two days later I got my bill and all it said was $365.00 with no explanation of any of the charges, just an amount due. When I booked the appointment they told me they really didn't have set rates and would look at the job on site and give me an estimate. I thought that was fair. However, That Never Happened. When I called to discuss my bill he said his plumbers got paid $200/hr and there was an equipment cost. I said ok but they were gone in 30 minutes. He said we don't bill anything less than an hour. I told him that I thought the charges were unreasonable, given the ease of the job and that no one ever offered me an estimate up front as promised before fixing it. He told me his people had to eat. I guess he forgot I had to eat too. Read reviews that are not 5 star. I wish I had.”

“I've been using Kelly Williams Plumbing since 2016, when we bought a San Marcos home to use as a college rental. From the very beginning, Kelly helped us get the house ready for our college-aged kids — and ever since, he’s been our go-to for all the quirky issues that come with owning a 1960s home. He’s installed disposals, toilets, sinks, and has kept our washer drain flowing properly, — just to name a few of the jobs he’s tackled. Kelly is incredibly easy to reach and, depending on urgency, usually has someone at the house within 12 hours. Now that the home operates as a short-term rental, Kelly continues to ensure our guests enjoy a smooth, plumbing-problem-free stay! I recommend Kelly Williams Plumbing to everyone I know in San Marcos and the surrounding area. Reliable, responsive, and always professional!”

“I have used Kelly Williams Plumbing for all my plumbing needs for over three years. They have handled my commercial repairs, new construction on five office/warehouses that I've built, residential remodels, and, of course, my personal plumbing needs at home. Kelly has never let me down and has gone above and beyond the call of good service every time I've needed help. I highly recommend them for any plumbing need or advice you may need. I have also personally recommended them to my friends and business associates, and they have delivered the same excellent service every time.”

“Excellent plumbing service. The gentlemen that came to our home were reliable, fast, and impressively thorough. They explained every step clearly, which gave me total confidence in their work. Highly recommend! I will definitely be using them for services again.”

“Kelly Williams Plumbing is the best there is. Called 3 other companies and couldn't even get them to show up. Kelly's guys showed up on time and did a perfect job. Plumbed my whole shop in less than a day and made sure I had water running. Cleaned up and I haven't had a problem in over 5 years. Outstanding work! I couldn't recommend these guys enough and if I am ever in need I know who to call! Don't make the mistake of trying someone else.”

“Quick work and a reasonable price. I used KWP when I remodeled a bathroom. We had a great experience. We called his company back to re-plumb our entire house. The work took 2 days but they made sure we still had water overnight. They treated us like family!!!😊 thank you Kelly Williams!”

“Rescheduled appointment two times on us. Was 30 minutes late to our 2 hour window. Made no direct eye contact upon thanking him for fixing our faucets. Then come home to my wife letting me know he forgot the two other faucets and scheduled for ANOTHER DAY after his mistake. Yikes. Would not recommend to anyone who likes good customer service or punctuality.”
