Recommended Customer Reviews

Magnum plumbing was always on time to the appointments. Aven was extremely helpful in assessing the job, recommending courses of action, and executing the plan quickly and efficiently. I would recommend to anyone and absolutely would call again for future plumbing needs. You would be crazy not to call Aven for your next plumbing project!

Aven and Hector were polite, professional and efficient. Aven responded quickly to an urgent request and the problem was fixed later that day. I'll definitely go with them again for future projects.

Aven and his team are top notch. He takes great pride in his work and it shows. We opened a new grooming shop and needed a tub installed on short notice and he was quick to respond and get it done. We would recommend them highly to anyone who needs an honest plumber who does great work!

We replaced our 12 year old water heater and called Magnum to do the job.
I highly recommend this company. Family owned and they really go the extra mile.
I will definitely recommend them to anyone with plumbing needs.

Professional and fast friendly! Hector repaired our leaking pipe. Great service, honest and friendly.

Aven was amazing. He found time in his busy day to help us out when a spicket broke to our washer. The water was everywhere and no way to shut it off without shutting down the whole house. He was able to plug it until he could get the right parts and came back the next day to complete. He was on time, pleasant, professional. Thanks so much!

Aven, the owner at Magnum Plumbing is dependable and knowledgeable. We called Magnum Plumbing when we had an emergency leak in one of the condos that we manage. We had a quick response. They came over, stopped the leak and then corrected the issue. Since the unit was vacant, I was concerned about turning water back on. Aven came over on the holiday weekend and made sure all was good. He cares about his customers. Pricing was fair and I would recommend him for any plumbing job. He is Zteam's plumber going forward.

Unfortunately only one star on this review. When he came the first time he needed just one more part for the toilet but had to order it. Aven said when he would come it would be on him , no charge and now I see why. I had to call him to see if he remembered. We did set up an appt around his schedule. He said he'd come between 8-10 and texted at 8:50 he was sick so, we reschedule. He was suppose to come at 8 this morning but canceled because his babysitter ""flaked"". I thought maybe he would reschedule for this week but that was a big fat NO. He texted me and said,"" see what your schedule looks like and will work out something"". Weather it be my schedule or his schedule there is obviously no worries about coming back. In fact his text to me was, "" Your toilet is working. This is not an emergency. This is a free service"". Evidently free puts you on the back burner. Aven wants to resolve this but it's to late. He gets a zero this time around and I will never use him again!

Magnum Plumbing was so awesome! He came right out and fixed my problems. Aven will be our plumber for now on! Thank you Tons from Illusions Hair Studio!!

These guys were awesome. Aven Was very professional and responded extremely quickly. We had a faulty faucet which he replaced and did so on very short notice. Pricing was very competitive and I would definitely go back to these guys no matter what. 6 stars
