Recommended Customer Reviews

I needed a bathtub installed, called Custom Plumbing and two men arrived the very next morning ready to work. They installed the new water lines and connected the tub drain and the overflow. The tub was installed on a bed of mortar to secure it, perfectly level when finished. The two men did a thorough clean up afterwards of everything, and were both extremely professional and polite. I enjoyed the great install as well as their company, kept me informed each step of the process. I'd defniitely use them again and would certainly recommend their services to anyone needing plumbing work.

The water heater in my new-to-me home has been consistently malfunctioning since moving in two weeks ago. CPS was listed as a certified service rep for AO Smith water heaters, which is why I called them. They were able to arrange for a tech to come to my home within the day to look at the existing water heater, quote for repairs and also quote for a new water heater dependent on the price to repair the existing one.
Due to the expense to repair the existing heater, I chose to replace it and arranged to have the new one- a different, and hopefully more reliable brand- installed the next day. The quoted price was higher than other tank installation estimates I had received by a few hundred dollars, but it was explained that there was extensive retrofitting that would need to be done, they would have to pull permits due to my home location, etc. Due to the other companies' long waitlists and my desperation for hot water, I scheduled the installation for the following day.
The techs showed up and got to work, and seemed competent at their jobs. However, they only informed me after I'd signed the paperwork and given my credit card info that they wouldn't need a permit to complete the job. Additionally, they left sawdust, bits of sheetrock, and water all over my utility room which seems unprofessional (photos attached.) They also forgot a couple of their things and forgot to turn my water back on before leaving. I feel that these issues collectively (especially the non-issue of the permit) adds up to a plumbing job not worth nearly the $1700 I was charged for it.
Had they offered to lower the price a bit upon learning that a permit and inspection would not be needed, cleaned up after themselves, and remembered to turn the water valve back on, this would have been a 5-star review.

I always use Custom Plumbing for my rental house in Austin. I no longer live in the state, and I trust them to do a good job. They've always come out when they say they will, take care of the issue quickly, send me receipts, and my tenants are happy. I see no reason to use anyone else as they've been helping with my property for years. They've done everything from installing a new gas tankless water heater on the outside of my house, to replacing an exterior spigot. Definitely recommend them.

Our "new" house had a rusty 20-year-old gas water heater sitting ominously in the attic, and I really wanted to replace it with a tankless model. As I quickly found, pricing, quality and ability to retrofit existing gas lines all vary widely from company to company. My usual plumber had little experience with installing tankless heaters. Custom Plumbing came highly recommended by a friend who had them replace her two tank heaters with a tankless last summer.
Barry, the owner, came out to assess the situation and gave me a very competitive bid. He was confident that it would work, and made several recommendations. We got on the schedule very quickly, and he pulled the necessary city permits.
His plumber and assistant showed up right on time, and then so did Barry! He made sure all the work went smoothly, and they graciously worked around a street construction crew that showed up without notice to work right in front of my house that day.
It was far from an easy job, especially with having to reroute some gas lines and to get the existing sediment-filled heater down the ladder and onto their truck. It must have weighed a few hundred pounds. I was really impressed with their knowledge, persistence, and diligence, because the entire job took about five hours from start to finish.
Electrical work needed to be done to finish the job, and Barry made some recommendations to that end, as well. The electrician I hired afterward had no problem finishing his part of the job, and commented on how nicely it was set up. We are super happy that we took the plunge to get a tankless installed, and I'd recommend Custom Plumbing for this type of work without hesitation.

I had a bad water leak, called and they came right out. Super professional and nice. Problem fixed! I will never call another plumber!

The customer service is atrocious. Make sure everything works before you pay them. The work is sub par and shows no signs of professionalism or pride. If you have a problem after they are paid you are on your own. Please consider another plumbing company. Hire a professional plumber and save yourself the headache!

I hired Custom Plumbing Services to come and extend a natural gas line for my BBQ. The owner, Barry, personally ensured I was a satisfied customer and that the job was completed on time and with finesse. He visited the site and was very responsive. The plumbers were professional and very respectful and the officer manager Terry was also extremely helpful. If you want a job done well and right and on time, I highly recommend them. I haven't had such high level of customer service with any other utility contracted, definitely a positive experience.

I called Barry at Custom Plumbing today regarding a propane leak under my building. I had a sense of urgency to get the repair done since being without propane affects my business. He and his team were awesome! They came out in a timely manner and had us fixed up and running again in matter of hours. He and his team were courteous, professional and did what they said they would - when they said they would do it. I was was charged a fair price for fair work! Thank you Custom Plumbing!

We had another great service from Custom Plumbing. The location was 2 hours away from Austin. Roger called Saturday am when he was on his way. Roger was able to find our gate which is good since we are down a county road with no house in sight. He was able to fix the leak promptly. He was effective and professional. Great job Custom Plumbing!

Get a quote before they come out. Because we were in dire need they felt like they could charge whatever they wanted. $395 for LITERALLY 15 minutes of work. Absolutely ridiculous.
