    Common Causes of Blocked Drains

    Dealing with a Blocked Drain in Thornleigh? Here’s What Might Be Causing It. Blocked drains are more than just a hassle – they can slow everything down, cause nasty smells, and even lead to water damage if ignored. Whether you’re at home or running a business in Thornleigh, here are some of the most common reasons your drains might be acting up:

    • Hair Build-Up
      Hair easily gets caught in shower, bath, and sink drains. Mix that with a bit of soap, and you have a clump that slows water flow and builds up over time.
    • Food Waste and Grease
      In the kitchen, pouring oil, grease, or food scraps down the sink might seem harmless, but over time, they harden and trap other debris, leading to stubborn clogs.
    • Foreign Objects
      Wet wipes, nappies, cotton buds, and even too much toilet paper don’t break down the same way toilet paper does. Therefore, they can block not only your drains but also the sewer line.
    • Tree Roots
      Tree roots are always searching for moisture, and your underground pipes are the perfect target. Once they find a small crack or joint, they can sneak in and start growing. Over time, this can cause a serious tree root blocked drain, restricting water flow and even cracking or breaking the pipe if left unchecked.
    • Mineral Build-Up
      Hard water in some parts can leave mineral deposits (like calcium or magnesium) inside your pipes. This narrows the pipe opening and reduces flow over time.
    • Damaged or Collapsed Pipes
      Older pipes can crack, shift, or collapse. When this happens, sediment and debris can easily gather in the gaps, creating recurring blockages.

    This company exceeded my expectation on every level, on a Friday afternoon my wife called frantic about an overflowing toilet, she spoke with a lovely lady in the office that was understanding and calmed my wife straight away assuring us we were in good hands and they definitely delivered. Two team members attended our property within 45 mins late Friday afternoon, cleared the blockage and cleaned up the mess, within 2 hours it was like it never happened! I am thoroughly impressed with this team from start to finish even the price was less than I expected. Will definitely use again and highly recommend to anyone in need. Thank you again WSG Group
