If you have a blocked sink in Winson, Gloucestershire the best thing to do is try and remove the blockage using some easy methods. First try using a plunger make sure there's enough water at the bottom of your sink for it to work effectively; if not add more boiling hot water until full then seal around any plugholes with cloth or towels before plunging up and down several times. Don't be disheartened if this does nothing as sometimes that won't clear blockages by itself! If this method fails you could use vinegar mixed with baking soda (1/2 cup each) poured into an empty bottle which should bubble when put through plughole - leave overnight before pouring boiled kettle-hot tapwater after 30 minutes & repeating previous steps again once cooled off slightly (not cold). You may also like to invest in drain snake or auger tool which can help unclog drains further depending on plunge effectiveness. Depending upon how long it's been clogged will determine how much time required overall but generally speaking these methods shouldn't take too long so don't panic!
