I had a great experience with ZND installing my new water softener and reverse osmosis system. The installation is clean, the team was professional, and the water quality is fantastic. I’d definitely recommend ZND to anyone needing water filtration upgrades.

Details: Water softener (most common) • Reverse osmosis • Point-of-entry filtration system for entire building • I would like to discuss with the professional • House

They were prompt in responding and were able to give me a great quote. Showed up right on time, the work was done quickly and very well. Very happy with the results. I would contact them again if I have any plumbing issues.

Had a quote from a very well known plumbing company. I was told I had iron pipes and needed special parts, they quoted me $2250. Called Z and D for a second opinion as they had great reviews. David came out, said there was no iron pipes, just plastic, fixed it for $250. Now my go to plumber!

Details: 1 toilet • Municipal water (most common) • House

Great experience! I had my bathtub fixtures replaced and was able to get it done the same day. David was professional. He assessed my shower and informed me that I didn’t actually need to have the valve replaced, therefore I was able to save some money. I plan to hire them again to do my second bathroom in the future.

Details: No, I do not need to replace a sink • As recommended by professional • 0 sinks • 3 faucets • Condo/Apartment

David did a great job adding a natural gas connection for our new weber genesis grill. The price was reasonable and the same as what was mentioned prior to arrival. He explained how the new fitting worked, had the job done in no time and hooked up the grill land tested that it worked before leaving. I also found that other plumbers wanted to charge $100 to come out and do an estimate, that would only be waived if you proceeded with the job, which gives them leverage to quote a higher amount. They would not provide an estimate before coming out. David gave a good value quote based on some photos I shared, which made the whole process easier. I would not hesitate to recommend him to others and I will be calling him for any future plumbing needs.

Details: Hook-up appliance(s) to existing gas line • Supply new gas line to appliance (outdoors) • As recommended by professional • Outdoor BBQ or grill • No, I will need the professional to provide the materials • Condo/Apartment
