Tub drain replacement
A leaking kitchen faucet was identified, causing water waste and potential damage. I began by shutting off the water supply to prevent further leakage. The old faucet was carefully removed, and the underlying plumbing inspected for any damage or wear. A new, high-quality faucet was selected to ensure durability and efficiency. The installation process involved precise alignment and secure attachment of the new faucet. Water supply lines were reconnected, and the faucet was tested for proper operation and leak-free performance. The job concluded with a thorough cleaning of the work area and confirmation from the customer that the issue was resolved.

So extremely pleased with the expediency of service by Jorge at Duncan Plumbing Santa Cruz. He arrived on time (actually early after getting a call to see if that was ok) for pricing consult/quote of a non-emergent water heater exchange, along with new connections, etc. While the price quote was not the cheapest compared to the others I'd already gotten, it was more inclusive of all the necessary work & needs. Jorge knew all the current rules/regulation entailed. He was also available to do the full project right away. I felt safe in his knowledge, capabilities, & space. So yay. Project done & no potential future worries about my water heater. So, grand thanks to Jorge. Also, must say that all prior phone/online contacts were very pleasant setting up my appointment. Duncan Plumbing has a wonderful team & they clearly care for their customers & about customer service. They even called me the day after just to check & make sure all was ok. They now have a customer for life & I'll be recommending them to my neighbors & friends. THANKS !!!
leak detection / fix
Great and speedy work by Jorge and Cecilio replacing our sump pump. We appreciated have them come on the day of our call to Duncan Plumbing.
Competent, informative, respectful
The plumber from Duncan was prompt, courteous, and explained the various options to me. He performed the work with care, and cleaned up after the job was done. Excellent service.
I appreciate that Duncan has an excellent reputation and I don't have to worry about quality. The guys who came out were very respectful, helpful and skilled. They gave me sound advice about a couple things that really didn't need to be replaced which saved me money and built trust. They took extra time to explain what they did. The cost is a bit of a sticker shock for me but it may well be comparable to everyone else - I don't have enough experience to tell. If it is a little more, the peace of mind that I get from the high quality work and trustworthiness of the workmen and company is worth it.
In my business as an architect and builder for the last 50 years I’ve been watching many plumbers and this company is really top notch. The technician they sent out was extremely capable and creative. Very efficient and ingenious guy.
