Minor blockages can sometimes be resolved with DIY methods, such as using a plunger or a drain snake. Products like baking soda and vinegar may help loosen light build-ups in kitchen sinks, while hot water can dissolve small amounts of grease. However, if these attempts fail or the blockage recurs frequently, it’s usually more effective and safer to consult a professional. Some DIY chemical drain cleaners can damage pipes, especially older ones, and pose risks to both your health and the environment. A qualified drainage engineer has the right tools—like high-pressure jetting equipment and specialist CCTV cameras—to locate and clear stubborn obstructions without harming your plumbing. They can also advise on preventative measures to reduce future blockages. Additionally, calling an expert ensures that any underlying issues, such as cracked pipes or root intrusions, are identified and addressed properly, preventing more significant—and more expensive—problems down the line.
