    Rennai tankless water heater installed indoors
    Clint G.

    After my conventional water heater started leaking after 8 years, it was time for a new water heater. I got quotes from other companies, but ended up going with Mr. Tankless because he was easy to communicate with and provided the lowest quote. I also trust his experience doing this for so long with central Texas water. The installation saved some drilling to the outside by utilizing an existing drain pipe. I'm happy with my upgrade!

    Mr. Tankless in Cedar Park delivered an exceptional experience with their quick response time. Their prompt service sets them apart, ensuring a reliable and efficient customer experience. I had just got my tankless water heater installed and it takes 15 mins to get hot water. The installer came by a few times and he assured me that's the norm. So I called Rob to see if we can get hot water faster. Rob and his team came by and it only few minutes to get the issue resolved. Now it only takes 6 second to get hot water. Mr. Tankless not only addressed the issue promptly their attention to detail and expertise made a noticeable difference in the efficiency of our tankless water heater. Highly recommended!

    New tankless system!!!

    Great value for a quality product and excellent installation experience. The showed up at 9am and had my old tanked unit exchanged/ new until up and running by 11am. Super happy with the work. I would recommend 100% to anyone need a new tankless unit!

    I had a 14 year old water heater go out, and after calling around a few places I landed on Mr. Tankless. Robert was a delight to talk with, a consummate professional and got me squared away with a new tankless water heater. Not only was he the best to work with, his cost was one of the more competitive to install. He was straightforward, no bs and the type of person i'd recommend to anyone. Stop searching, you've found the right person to install your water heater.

    The fully installed system in our attic. It's performing amazingly well.

    Bob and his worker came out to our house after our old tank heater started to leak from its inlet. They quickly assessed our situation and were able to offer a very competitive quote for a highly rated Rinnai tankless water heater. He gave me the quote in writing and left us to consider our options. After I reached back out to him, he gave me a date and time window when he and his worker Brandon were able to come out to our house. He texted me letting me know he was on his way and he arrived right on time. They completed the installation of the new heater in the amount of time they estimated and they showed me how the bypass system worked for annual maintenance. The system has been performing incredibly well, we're able to have as many people bathing as we want which was something our old tank heater could never accommodate. I really recommend Mr Tankless, they were professional, arrived on time, did a great job, and offered a fantastic price. I wouldn't hesitate to hire them again for any plumbing job.

Avi was an absolutely delight. Fast, clear communication before the initial meeting. Very thoughtful approach in our initial meeting. So many images from their highly impressive portfolio to help us think through options. Excellent examples of communication and workflow from previous projects. Instantly ready to share previous customers we could reach out to for references. A really good balance between sharing his ideas for our project, but also really listening to our feedback on what we wanted/invisoned. All the right insights for how to keep us in budget, and very generous with (we can add this/that for little/no extra costs since we're already doing XYZ). We mainly requested a bid on two projects (Kitchen and Primary Bathroom) and help deciding the scope for the remainder of our projects (Flooring, Guest Bath, Office, Patio, Etc.). We were very impressed with how realistic, but also open-minded he was with what portion of our "bonus" projects we could fit in. The formal quote came in fast after our initial meeting, was easy to follow, and fairly priced. Found the proposed timeline to be very well balanced for efficiency vs realism. Appreciated the suggestions provided for if we should/could "live-in" during the remodel vs. a timeline that would allow the bulk of the work to overlap with a time that we were going to be out of town already. Also insights on what it would be worth "buying in advance" to take advantage of sales, even if the actual work was delayed. We got a few quotes and would have felt confident moving forward with any of them when the time came, but the quality of their portfolio and Avi's attentive listening definitely put Teamwork Home Designs at the top of the list. Can't wait to work with them in the future.

The team appeared comfortable working on bathroom renovations; however, the shower diverter was not installed correctly, which caused the handle to be improperly aligned. We later hired a licensed plumber to inspect and correct the issue. Overall, the quality of work did not meet our expectations. Some aspects of the workmanship appeared rushed, and based on our experience, I would recommend exercising caution with detail-oriented tasks such as wood staining, drywall, painting, or door hardware installation. This project did not go as smoothly as anticipated, and I would not choose to work with this company again.

Was very impressed with how quickly they were ready to begin the work, and the forethought of asking us if we planned to "live-in" during the remodel vs. get an AirBNB or the like. We hadn't even thought of that. Would have been very confident in moving forward with ATX Remodeling. Especially as Koren had so many examples of the type of elaborate communication and oversight we would have at every stage of the process.

    We have a ground level wooden patio with a metal veranda that was in sore need of having the…read morefloorboards replaced. Initially, we planned to do the work ourselves. We bought/stained pressure treated lumber and did the demo work of pulling up the old porch. We soon discovered to our dismay that the underlying frame and columns holding up the veranda were varying degrees of rotted-out and needed to be replaced entirely. We wanted the job done right, and so we decided to find a contractor to work with. After doing some research on Yelp, I reached out to a handful of deck building specialists. Originally, Deck N Cable Railing wasn't even on my radar. Yelp has the function that if you click a button, it'll automatically duplicate your request and send it to an additional handful of businesses. I didn't even realize that I had accidentally done this. I'm so glad I did because Deck N Cable Railing was one of the businesses that Yelp sent my way. First off, they were very fast at responding to my request for info. They reached out, asked for a bit of additional information, and then offered to come out to give a free estimate in person within 24 hours. Juan Pena, the owner, arrived on time for the appointment. He listened attentively to our needs and evaluated the job that needed to be done quickly, efficiently, and thoroughly. He was sensitive to our desire to not let the lumber we had already bought/stained go to waste and made a plan to utilize it. He was also able to give us a quote on the spot which was really helpful. On the day of the installation, Juan arrived with his crew members, Jovial and Alejandro, to help get this situated for the job before he left for the day to attend to other projects. Jovial and Alejandro spoke limited English, but they used their smartphones and Google Translate to communicate with me when a question came up and so communication worked out just fine. Jovial and Alejandro were friendly, professional,and very hard workers. They were fast and fastidious and kept the job site neat. Juan had said that it may take up to two days to finish the job, but his crew were almost complete by the end of the first day. There was a minor issue with the frame visibly sticking out just a bit at one corner of the terminating edge of the porch. It wasn't a structural issue, more of a minor cosmetic issue, but I discussed the issue with Juan, and he immediately came up with a suitable solution to address my concerns. He joined Jovial and Alejandro on the morning of the second day of the installation to personally inspect their work. The job was finished within an hour or two on the second day. All in all, Juan and his team did an excellent job with the porch. It looks fantastic and feels exceptionally sturdy. We're very happy with the quality of the work, and we are looking forward to enjoying it for many years to come. We'd recommend Deck N Cable Railing without reservation based on the quality and efficiency of their work alone, but that's not the only reason you should consider giving them a call. Juan was very easy to work with. He's professional, responsive, friendly, and conscientious. He takes a lot of pride in his work and it's important to him that his clients are 100% satisfied with the work done. Moreover, his pricing is very reasonable. His quote for the job was by far the most reasonably and competitively priced bid. Finally, and this is a bit embarrassing, I accidentally overpaid for the job. I paid Juan in cash, handing him an envelope with cash, without realizing that I had miscounted it. Imagine my surprise when I got a call from Juan that evening (apologizing for calling so late!), to let me know that I overpaid him, and he wanted to schedule a time when it was convenient for me for him to stop by in person to return the amount I overpaid. That's integrity, folks. If, like me, Deck N Cable Railing isn't on your radar, they should be. Solid 5 stars.

That's a bunch of crap. They don't know what the rest of my deck looks like. They never bothered to come out and look at it. This rest of my deck is in good condition because it's covered and out of the elements. The area of the deck I want repaired is uncovered and exposed to the elements. This company is a joke and all they want to do is upsell you. Beware of this company!
