Called on a Friday but scheduled for the following Monday to avoid the weekend service fee. They called back within 2 hours with an immediate opening as another job was finished earlier than expected. As always with this company, the fix was completed quickly and competently. I’ve used Duncan plumbing many times and highly recommend.

Review
This call was to fix damage caused by a water company error. Nui quickly assessed the damage, coordinated with my park manager, and fixed the problem. I also requested an estimate for repairs/replacement of my outdated fixtures. Nui was thorough in examining my existing plumbing, including a trip to my crawlspace. He prepared an estimate, explaining basic work as well as options for repair and replacement of non-standard fixtures. I wasn't surprised that this work would be costly, but I was satisfied with his explanations and felt I understood enough to make educated decisions going forward. As this visit was paid for by the water company, I have not rated cost/pricing of work done.

I’ve used Duncan Plumbing for years. They always fix things at a reasonable price. Since I have a horse barn, some of my plumbing problems can be a bit different, but every one has been solved and hasn’t reoccurred. They always show up on time, no waiting around. That fits into whatever my schedule is very well. Can’t recommend them enough!!!
