I manage two duplexes and Diamond has been my go to for five years. They helped fix a botched job (someone else botched, not Diamond) as our very first service and have been prompt with communication, help and guidance ever since. Any job, I go to them.

The experience with Diamond Plumbing Heating and Cooling is always very professional. The plumbing education and plumbing experience that Julian brings to every service call is reassuring and at reasonable expense. Julian always responds very timely and does an excellent job with full resolve. Nice service company with great employee(s). Thanks!

My experience with Diamond was great. I appreciated how coordination happened via text, which was convenient for our family. Though our original appointment was delayed, Julian kept me updated so I knew what was happening, and came to complete the job himself so we didn’t have any further delays. He found the source of an odor coming from our bathroom sink pipes, took care of it, and checked in a few days later to make sure the issue didn’t return. Price was totally reasonably for the job. I’d definitely recommend his services.

I called re two clogged toilets around 5:30 pm. The process was seamless with very clear instructions and the level of services provided. I appreciated the service agreement that was promptly sent to me prior to the technician coming. Technician was scheduled for 9:30 pm but arrived early at 7:55 pm. Julian was professional, friendly and knowledgeable. Thoroughly assessed our situations and gave tips to ensure it would be less likely to happen again. He was in and out in less than an hour. Diamond Plumbing gave me top tier service. I would def recommend them to anyone.
