I just moved into a new house and wanted to replace all the toilets with cool looking and water efficient dual flush units. As I waited for the toilets to come in, other issues popped up like needing a new kitchen faucet, sink stoppers that didn't work, and other minor issues. When Nick and Zack came out they immediately put booties on which was great since i just had new carpets put in two days prior. They took a look at the toilets and set to work. They showed me the valves and all the corrosion present and replaced them with very high quality valves and they replaced the crappy plastic water supply with steel mesh. My dad was here helping and was an insurance agent for 37 years and asked about that as he has seen so many claims due to low quality plumbing products. He was very impressed with all their "standard" products they used.
The toilets were very tricky to install as they are one piece, dual flush, but they installed them without issue (reviews on toilets warned of other plumbers or DIY guys having major trouble with them) and then moved on to the faucet. That also was tricky due to the reverse osmosis system I have and the monster 1 HP disposal. They had to remove both to properly install faucet but did not charge extra, nor did they charge for the replacement they did on the RO plumber's job.
I never write reviews but these guys stood out for great prices, education they gave me on everything, cleanliness, and jist how nice these two brothers were. they are coming back out to install the third toilet when it arrives and they will be my plumbers going forward for anything I do. You can't go wrong with Nick and Zack.
