"A first time apartment owner and landlord, I needed major plumbing services within the first 6 months of ownership. The first time was a series of gas leaks which were quickly repaired by Western Rooter. The second time was the significant work of adding 2 gas meters and the requisite task of re-routing/adding gas piping. I simply cannot recommend Daniel Westereng and Western Rooter enough. Although the owner John came out to assist in the final bid, Daniel and I worked consistently with SoCal Gas to coordinate the improvements. Daniel was quick to return texts, calls, e-mails and worked diligently with all the parties to get the job done. If you need a plumber, save time and call Western Rooter. Tell them to send Daniel Westereng and he will do a fantastic job!"

"Alex with 805 Plumbing was quick to respond to our request for help with our septic system. He offered options for us to deal with the problem, and allowed me to watch as he diagnosed our situation with the use of a camera. I never felt pressure to take a path that would be more expensive, and every step of the way I was kept informed of what he had discovered. I am confident that our problems were efficiently taken care of, and although I would not wish septic problems on anyone I would recommend Alex and 805 Plumbing to anyone who is in need of plumbing services. Alex is a reliable, fairly priced, professional, and experienced plumber, and I will use him again in the future."

"I had a great experience with Fix It Quick Plumbing! They came out to unclog my washer drain and lived up to their name—fast, efficient, and right on time. Armando was professional and got the job done quickly without any hassle. Best of all, the pricing was totally reasonable and within my budget. Definitely keeping them in mind for any future plumbing needs!"

"This company was amazing. They called in under a min of my posting. They were at my house within the hour. Alex and his son were best , courteous plumbers I have met in my life. And I have dealt with many plumbers. They diagnosed the issue, which was major, my entire main drain system from under the house to street failed in multiple areas. House was 71 years old. Original inspection showed some of the issues but not all. They were downplayed by the inspection to help sell the house. Price was in range. The stayed on the job never late each day until complete. They cleaned up and fixed lawn perfectly. They were pleasant and informative to be around. I Recomend this company and especially Alex to anyone. I don’t think I’ve been this impressed with a plumber in y life. So with no pun intended,”hats off to Red Hat Plumbing."

Plumbing FAQs, answered by experts

Delaying plumbing maintenance in Thousand Oaks leads to severe hard water scale buildup, which destroys water heaters and fixtures. Local clay soils shift during wet and dry cycles, turning minor under-slab leaks into major foundation damage. You also risk facing water waste penalties for unrepaired leaks during drought restrictions. Address issues immediately to protect your home from hidden mold and extensive structural damage.

Helpful?

Before starting plumbing work in CA, verify that your hired professionals hold active, valid licenses. Secure all required local permits for water heater replacements or sewer lateral modifications. Check current drought restrictions to ensure your planned fixtures comply with local water use rules. Confirm your property lines to understand your exact responsibility for sewer laterals, and ensure new appliances meet state seismic strapping requirements.

Helpful?

Hearing running water inside walls or finding cracks near bathrooms indicates a plumbing slab leak rather than a structural defect. Unexplained wet spots in your yard point to broken irrigation lines rather than normal clay soil drainage. If you experience low water pressure in Thousand Oaks, check local utility alerts first to rule out municipal supply issues before scheduling a plumbing repair.

Helpful?

Keep basic descaling materials on hand to clear hard water mineral buildup from your showerheads and faucet aerators. Because Thousand Oaks sits near active fault lines, you must know how to access your main water shutoff valve. Maintain basic drain-clearing tools to manage tree root intrusion in clay soils. Keep a dedicated file of your required annual backflow test records for outdoor irrigation systems.

Helpful?

In CA, hard water rapidly fills water heaters with sediment, requiring frequent flushing. Homes built on concrete slabs face a high risk of under-slab pipe leaks due to shifting clay soils and interior corrosion. You must also maintain outdoor irrigation backflow preventers and pressure-reducing valves. Older homes require immediate replacement of galvanized or polybutylene pipes to prevent unexpected ruptures and severe water damage.
