Blocked drains

If you're noticing slow drains or water backing up in your sink, shower, or tub, these are signs of clogs that need to be remediated. One of the most common issues we see is grease build-up in drains. This is often caused by cooking grease being poured down the drain. Over time, it builds up and restricts the flow of water, causing slow drains and eventually a complete blockage. Tree roots can also be a major problem for residential plumbing systems, causing clogs and blockages in your pipes. Our team of plumbers is skilled in clearing tree roots from drains, using state-of-the-art techniques and equipment.

No matter what type of drain you have, National 1 Plumbing has the tools and experience to get it running smoothly again. From simple clogs to complex drain blockages, we have the knowledge and equipment to get your drains flowing freely again.
