The information on FaultToFix is general information only. It is not professional advice, and it is not a substitute for advice about your own home, your own boiler, or your own wiring. Every home is different, and a symptom that looks minor can have a serious underlying cause.
Gas work
Do not attempt gas work yourself. In the United Kingdom, gas work must be carried out by a Gas Safe registered engineer. In the United States, use a licensed technician. If you smell gas, leave the property, do not switch lights or appliances on or off, and call your gas emergency service or local emergency number.
Mains electrics
Mains electrical work must be carried out by a qualified electrician. Do not open consumer units, touch exposed wiring, or work on circuits you do not understand. If you see burning smells, scorch marks, or breakers that keep tripping, switch off the affected circuit if it is safe to do so and call a qualified electrician.
Mould, damp, and structural concerns
Small, surface-level mould can often be cleaned following the guidance in our articles, but large areas of mould, mould that keeps returning, damp that affects structure, or cracks that are widening, uneven, or near doors and windows should be checked by a professional. If you rent, tell your landlord. If the problem affects a shared building or public housing, contact your landlord or local council.
Your responsibility
You are responsible for deciding whether a check or repair is within your ability and for following local laws, building codes, and manufacturer instructions. FaultToFix is not responsible for damage, injury, or loss resulting from work done on the basis of general information on this site. When in doubt, stop and ask a professional.
