"Edgar led the project . He and his team were timely, knowledgeable, trustworthy and conscientious. The most caring and thoughtful plumber I have ever worked with. I have an old house so future plumbing issues will arise. Aaron’s is the first and only call I will need to make."

"We thought we needed just our washer drain unclogged so we called the company that had fixed that before, you guys. Guys came out. Under the house they discovered rusted sewer lines. When we had our plumbing redone years ago, the company who did those did not remove the old lines. Those old lines were up against the sewer lines and were corroding our sewer lines. So we had to replace the sewer lines. A broken line just before the city line was discovered so we had to replace that too. Anyhow, we so appreciated the kind workers who smiled and waved at us. They worked around our water schedule as we have a physically disabled adult son we care for. They let us watch all the things they had to do. I took pictures and the guys were fine with that. My brand new front yard was not ruined by trenchless sewer system that went in. And my yard looks like we never had sewer lines done. It was amazing. Yes, we would recommend you to all."

"I was able to contact Matt, the owner, at 8 p.m. and found him very helpful and informative.  I called back at 7 a.m. the next morning and was able to schedule the job for later the same day. 
Technician Mike arrived early and thoroughly reviewed the scope of the work.  He went about replacing the water heater in an efficient manner.  He also installed a new metal stand for the water heater, all new supply lines, and installed a new supply line for the gas dryer hookup.  He took time to add necessary spacers to the rear of the water heater so that he could properly strap it.  The job took just under 2 hours.
The cost of this job was half the price quoted by two other full-service plumbing businesses for the same brand water heater. We feel confident with the quality of all the material and workmanship and feel that we definitely got our money's worth.  Overall we were very pleased and would highly recommend them.

"After talking to Jaime of SWAGS, I was made aware that it was not his company who did the plumbing work in my house, but anothe company. My apologies. Jaime was also kind enough to tell me that his company makes sure to be on the appointed time or if not, that their customers are reasonably informed of any delay. His company would have been my first choice since he told me he tried contacting me 3 times and did not get any call back from me. It must have been the day or days when I was having problems with the phone service. If only for his effort to reach out and that he was nice enough despite the mistake speaks greatly of professionalism I will definitely give his company a call the next time the need arises."

"On Sunday night our sink drain started leaking all over our kitchen. By Monday 6pm, Wilmar Bautista and co fixed it, found several other issues and fixed them too. I DIY a lot of my plumbing so Mr Bautista was even so kind to give me a few pointers and tips of things to be mindful of. You can't get a plumber better than these folks."

Plumbing questions, answered by experts

Install anti-scald mixing valves in your showers to protect children from sudden hot water burns. You must also add backflow preventers to your outdoor irrigation systems to keep harmful soil bacteria out of your drinking water. Cap all exposed outdoor pipes so pets cannot chew on them. Upgrading to lever-style faucets makes everyday plumbing use much safer and easier for little hands across California.

Helpful?

Watch for sudden increases in your tiered water bills, which point to hidden leaks. In many older Sunnyvale homes, discolored water indicates failing galvanized pipes that require immediate replacement. You should also check for white mineral scale buildup around fixtures caused by hard water. Schedule plumbing updates if your home has original pipes to prevent severe damage and ensure a safe water supply.

Helpful?

Always schedule a final city inspection to close out your permits properly. After finishing plumbing work on supply lines, flush your cold water taps for several minutes to clear out any trapped sediment. You must also verify that all new fixtures meet CA water efficiency standards. Keep all your inspection records and contractor documents safe, as buyers demand them during future home sales.

Helpful?

Upgrading your plumbing directly eliminates health hazards like lead exposure in older homes. Replacing corroded pipes restores proper water pressure and prevents hidden moisture damage inside your walls. By addressing root intrusions in your sewer lateral, you prevent foul odors and dangerous sewage backups. These updates make your Sunnyvale home much safer, more comfortable, and highly resilient against strict local water restrictions.

Helpful?

Account for active seismic zones by installing flexible gas line connectors and automatic shut-off valves to protect your property during earthquakes. Sunnyvale features expansive clay soils that shift and crack underground sewer laterals, making camera inspections essential. You must also select high-efficiency fixtures to comply with local drought regulations. Hire a licensed professional to handle all permitting and ensure your plumbing meets current codes.
