Great Service Great Job

Nui and Araceli are a great team. Nui fixes my plumbing better than any other plumber and Araceli connects with my heart to communicate/hear my concerns. They treat me like family. Duncan Plumbing is the best!!

Amazing Service— Best plumbing experience ever!

This work was amazing across the board— the service technician was extraordinarily knowledgeable when first visiting. He provided us with multiple options in fixing the problem of roots in our drain with on point estimates. When he returned to fix our drain, the plumber and his partner did an amazing job. I would recommend Duncan plumbing above all other plumbing companies— well organized, responsive and knowledgeable work that goes above and beyond.

Prompt response!

I had a water leak on my heater and called Duncan for help. Within half a day they had a tech on site which is remarkable as we are in the SC mountains. He had the situation assessed and had a replacement installed by evening incl some non standard hook ups. Great job!

Excellent job , not only fixed current problem, but did significant repair to keep it from happening again

These guys were knowledgable, equipped, fast, and cleaned up well. Couldn't be better.

good service with a complicated project

Eric's first diagnosis and fix didn't quite do the trick (fixing a boiler) and he had to study and contact the manufacturer. He got some guidance and was able to make the repair. Ended up working well for a reasonable price.
