AS PLUMBING & MECHANICAL INC.

AS Plumbing & Mechanical Inc. runs as a family-owned plumbing outfit based in the Fontana area of Southern California. They started handling work in 2002 and have since added an Arizona license to cover more ground. The focus stays on residential and commercial plumbing needs across that region with options for same-day scheduling. Crews manage calls in both states from a central setup that keeps response times tight for local homeowners and businesses alike. This background gives them a practical edge when pipes or systems fail without warning in the heat and dry conditions common to the area.

They handle 24/7 emergency plumbing along with drain cleaning through hydro jetting methods to clear tough blockages. Water heater repairs and replacements form a big part of daily calls while leak detection tools help spot issues in walls or slabs before they spread. Gas and water line services fix breaks or upgrades and fixture work covers everything from toilets to appliance hookups in homes and shops. In places like Fontana common jobs include clearing roots from lines or swapping out old heaters that fail during peak summer use when demand spikes. These tasks keep systems running steady despite the local soil movement and hard water that wears on materials over time.

Customers keep coming back because the work shows up on time with clear explanations of costs and fixes that hold up without repeat visits. Speed on emergency runs stands out along with quality on repairs that match what was promised and prices that stay straightforward. Communication stays direct so homeowners know the steps ahead of any digging or part swaps. DIRT Score 4.98 from 659 reviews on Finds.

“From the beginning of my plumbing issue, I was greeted with courteous and polite responses from Andrew and his team. They gave me multiple options to keep costs low, allowing me to excavate myself and checking in to see how progress was going. Once main line break was found, the biggest tree root was the culprit and with my tools at home not being able to cut it out, they redid the scope of work and still kept the until project under 1k. I've saved their number and will be a repeat customer (hopefully not to often). Thank you guys”

“Corey is the kind of plumber you hope to find. He responded quickly, diagnosed the issue right away, and clearly explained my options without any pressure. The repair was done efficiently, the workspace was left spotless, and the price was exactly what he quoted—no surprises. He’s professional, punctual, and genuinely friendly. I also appreciated the small touches, like testing everything twice and sharing tips to prevent future problems. I wouldn’t hesitate to call Corey again or recommend him to anyone needing reliable plumbing work.”

“Sean from AS Plumbing did a great job. We had a pinhole leak on our 2-inch commercial copper main line, and he was professional, knowledgeable, and easy to work with. He replaced both 90° fittings instead of just the leaking one, which I really appreciated. The repair was clean, and I wouldn’t hesitate to use AS Plumbing again. Highly recommend”

“I had a great experience with this plumbing company from start to finish. Scheduling was easy, they showed up on time, and the technician was professional, knowledgeable, and respectful of my home. They clearly explained the issue, walked me through the solution, and completed the work efficiently. Pricing was fair and transparent—no surprises. I really appreciated the attention to detail and quality of work. I would absolutely recommend them and will be using them again for any future plumbing needs.”

“⭐️⭐️⭐️⭐️⭐️ Absolutely outstanding service from A.S. Plumbing! The quality of work is top-notch—quick, clean, and extremely professional. Ruby's customer service is exceptional, both over the phone and in person. The technicians were proficient and made me feel like part of the family from start to finish. Highly recommend!"”

“Gustavo did an awesome job. I’m giving 3 stars to the owner/manager. I requested to have a detail invoice that itemized the cost of each item being replaced/repaired, labor cost, parts etc. However, I was told that couldn’t be done and instead received an invoice with the job being done bundled all together under one price as a flat fee. I previously had work done with AS Plumbing back in September of 2025 when Frank (who was also awesome) installed my new garbage disposal. So, that was the reason I returned to AS Plumbing today to have my sink unclogged and p-trap cut and replaced. But after my experience today with the manager/owner I doubt I will return for future repairs. Again, Frank and Gustavo both did great jobs and administrator Rubi was very professional and friendly. 05/13/26 F”

I had a good amount of questions which she was able to answer and give me peace of mind. Overall I would definitely recommend both Courtney and AS plumbing to my friends and family !”

“Excellent customer service from start to finish. Called with an emergency water leak from upstairs bathroom to kitchen ceiling. Representative answering my call was very professional & friendly. She had a plumbing technician at our home within 2 hours. Technician was able to diagnose and fix our leak (shower caulking) within 3 hours. Technician was also very professional & polite. Will definitely call AS Plumbing & Mechanical again for future work.”

“Courtney is a great representative for the company. If you’re looking for reliable plumbing service in the Fontana area, I highly recommend starting with her. She’ll take great care of you from the very first message or call. Thank you, Courtney! Keep up the excellent work. 👍”
