A strong odour in your house can stem from various sources, and identifying the root cause is crucial to eliminating it. Common culprits include mould and mildew, which thrive in damp areas like bathrooms, basements, and under sinks. These fungi release a musty odour that can permeate your home. Another source could be leftover food or garbage, which can produce unpleasant smells if not disposed of regularly. Pets, particularly if not bathed periodically or if their bedding isn’t cleaned often, can also contribute to strong odours.
Additionally, poor ventilation can cause stale air to accumulate, trapping smells inside. Carpets, upholstery, and other fabrics can harbour odours from spills, pet accidents, or general use. If your house smells like sewage, it could indicate a problem with your plumbing, such as a blocked drain or a leak in the sewer line. Cooking with strong-smelling ingredients like fish, garlic, or spices can leave lingering odours. To address a strong odour, thoroughly clean your home, ensure good ventilation, and check for hidden issues like mould or plumbing problems.
