We have used RT Olson Plumbing more than a handful of times this past year. They are always prompt, professional, and easy to book with. We have specifically had Shane out to the house for all of our services. Whether for emergency repairs or regular plumbing needs, Shane has been a godsend. He is always helpful, informative, and professional. Thank you Shane and RT Olson Plumbing.

RT Olson is great with their work and prices. Gabriel and Santos worked with me to resolve my issue with my main sewer drainage. I had roots growing into my drainage they cleaned it out and then did a Trenchless sewer repair and also installed a two way access to the line. For future access. They responded quickly and got it resolve as quick as possible.

We hired RT Olson plumbing for a leak we found in one of our bedrooms. David G. came out the same day to diagnose the problem. He returned the following day with Junior and found we had a slab leak. Since the minute they walked in the door they were very professional and polite. David informed us of our options for repairing the issue without any pressure or trying to sell us on one particular option. Since both our bathrooms were out of commission he offered to prioritize our home early the next day to do a temporary re route so we’d have at least one of our bathrooms working. He and Junior came out early the following day and completed the job efficiently and with cleanliness. David has done an amazing job working with me on what was needed in the home and Junior never failed to ask permission or be polite the entire time. Thank you RT Olson for hiring not only knowledgeable professionals, but also well mannered people.

5 Steps to Finding the Best Plumbers in Corona California

  1. Reputation – ask friends and family, check online reviews in Home Advisor, Yelp, and Google. Do they have references you can call? Be sure prospective contractors have lots of customer reviews on several platforms. If you see a bad review, be sure to take notice of how the business responded.
  2. Check their contractors license and insurance, all of which is easy to do online at the CA Contractors State License Board. See ours here:
  3. Communication – how easy is it to connect to a real person at the company? Do they respond quickly to messages? How’s the mojo when you talk with them? What’s your gut tell you?
  4. Project Profiles – ask to see photos and case studies of previous work and provide references if your job is big. Do they have any before and after photos for jobs like yours?
  5. What’s the cost? Are they charging a flat fee for the job or an hourly rate, or hourly plus parts, etc.? You need to know. The best deal may be a flat rate for the job, that way you know exactly what you’re in for.

About Corona, CA

Corona (Spanish for “Crown”) is a city in Riverside County, California, United States. As of the 2020 census, the city had a population of 157,136, up from 152,374 at the 2010 census.

The cities of Norco and Riverside lie to the north and northeast, Chino Hills and Yorba Linda to the northwest, Anaheim to the west, Cleveland National Forest and the Santa Ana Mountains to the southwest, and unincorporated Riverside County along the rest of the city’s borders.

Corona is approximately 48 miles (77 kilometers) southeast of Downtown Los Angeles and 95 miles (153 km) north-northwest of San Diego. Corona, located along the western edge of Southern California’s Inland Empire region, is known as the “Circle City” due to Grand Boulevard’s 3 mi (4.8 km) circular layout.

It is one of the most residential cities in the Inland Empire, but also has a large industrial portion on the northern half, being the headquarters of companies such as Fender Musical Instruments Corporation, Monster Beverage Corporation, and supercar manufacturer Saleen.

== History == === Etymology === Corona is Spanish for crown or wreath.

Originally called South Riverside, citizens wanted to distinguish their city from the larger city of Riverside to the north. When it came time to incorporate the city a number of different names were considered, but the name Corona was chosen to play upon a unique feature of the city, the one-mile diameter drive that circled the center of the town.

=== Early years === Corona was founded at the height of the Southern California citrus boom in 1886, and is situated at the upper end of the Santa Ana River Canyon, a significant pass through the Santa Ana Mountains.

Julie - Corona, CA 92881

Review of RT Olson Plumbing

RT Olsen is professional and courteous. I’ve had them arrive the same day. Alan was our plumber who arrived. He’s been excellent both times and we hope he’s sent out again if we ever need a repair. Alan of RT Olson answered all our questions regarding a broken water heater and made the process of installing a new one easy. We were up and running with hot water the next day. The ease of the process and the professionalism made the cost of what is often an expensive repair sting a lot less. He even helped unclog my kid’s bathroom sink while he was here. It’s the extra mile that makes for outstanding customer service. RT Olson has that. We will definitely be using RT Olson again and have already referred them to others.
