Costs around £25 (2013) for a typical DIY door or window pack
What are the technical details?
Draughts are common in most houses, particularly older ones with suspended timber floors and single glazed windows. Although it is considered necessary to let a house “breath”, most of the ventilation is unnecessary and results from defects rather than design and is particularly bad in windy conditions. Double glazed replacement doors and windows normally have draught strips built into the frames.
Unwanted excess ventilation (draughts) will originate from several places, particularly the opening sashes of windows and around timber doors. These can be easily reduced by fitting draught strips to the frame. At the same time you should check the gap under external doors and fit a draught strip to the bottom of the door, an internal flap to the letter box cover and keyhole plates.
Other areas to check will include around the loft hatch. A lack of draught proofing will induce draughts in other parts of the house. The same is true for unused chimneys where the up-draught will draw air from the room. This can be reduced by fitting a temporary “chimney balloon” to reduce the size of the chimney opening.
Suspended timber floors over a ventilated void are responsible for many unwanted draughts. Curing this problem may not be easy but it can be improved by filling the gaps between floor boards and under the skirting board. A carpet with a good quality underlay will also help, but don't block the under floor ventilation though the air bricks in the outside walls.
This could be completed as a DIY job with most of the materials readily available from DIY stores.
