Today was my first time using Cast & Copper Plumbing & I had a wonderful experience. My old toilet was broke & they replaced it with a new toilet. Not only were they fast & efficient they were very friendly & professional. I would definitely use them again & they even took the time to clean up when they were done. I highly recommend them.
I’ve used Cast and Copper a few times. They never fail to impress. Whether it’s a minor leak or a full fixture replacement, they are always on time, courteous, and provide high-quality work. They are my go-to for all plumbing needs.
