Steps
Close each window and door, then run your hand around the frame and edges. Mark any spots where you feel cold air coming in.
Open the window and check the hinges, handles and locking points. Tighten any loose screws with the correct screwdriver, but do not overtighten them.
For uPVC windows, adjust the hinge screws with an Allen key in small turns. Move the sash slightly towards the frame where the draught is worst.
Turn the locking cams or keepers a quarter turn with an Allen key so the window pulls in tighter when you close the handle. Test the window after each change.
On doors, tighten the hinge screws. If the door still sags or leaves a gap, replace one short hinge screw with a longer screw that reaches the frame stud.
Loosen the strike plate screws and tap the plate a few millimetres towards the door. Tighten the screws and check that the latch clicks in without forcing.
Clean and dry the frame where the seal sits. Fit new self-adhesive foam or brush weatherstripping along the gap, compressing it slightly when the window or door closes.
Fit or adjust a door bottom brush or draught excluder so it touches the floor along the full width. Open and close the door to check it does not drag.
Lubricate hinges, locks and moving parts with silicone spray, then test every window and door from inside. Ask a helper to hold a door steady while you work on its hinges.
Tips and common mistakes
Adjust hinges and locking points a little at a time, then test the window or door before making another change.
Never force a handle or lock shut; a tight seal should still let the latch click easily.
Replace flattened or torn seals rather than adding more foam on top, because thick layers can stop the window closing.
Work in dry weather and keep silicone spray off glass and painted surfaces.
Questions
How can I find the draught around a window?
Run your hand slowly around the frame, sash and seal on a cold windy day. A lit incense stick or tissue held near the gap can also show moving air.
Can I adjust uPVC window hinges without taking the window out?
Yes, most uPVC hinges have Allen key screws for small horizontal and vertical adjustments. Turn them a quarter turn at a time and test the close.
What if the door still leaks after adjustment?
Check the seal and door bottom first, then look for a warped frame or worn hinges. A badly warped door may need a new seal or a professional repair.
