Get matched with top water treatment pros in Diamond Bar, CA

"Just had a water system installed, including RO, carbon and water softener. Only been running a few days so still have to see performance over long-haul. Brad has been very helpful so far and Jack and his team did a good job with the install. They've been responsive to questions, and also came back to install a water pressure regulator for a reasonable cost. So far, so good with ProWater."

"Very happy with my new 3-stage whole house water filter/installation - topnotch!!!"

"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"The plumber was very knowledgeable and professional. They kept the job site clean and we are very happy with the results."
