How To Seal Draughty Doors


For the tops and sides of doors, follow the same procedures as for windows. Again, the better the quality of the sealant strip, the longer lasting and neater in appearance it will be. But with doors, the biggest draught problem is usually created by a gap at the bottom. A speedy, but only temporary, solution to this problem is to tack a strip of rubber to the bottom of the door.

Cut a strip of rubber or vinyl from a sheet to the width of the door and about 30mm deep.

1. Offer up the strip so that it just touches the floor and mark where the top of the strip falls on each side of the door.

Hold the strip in place and secure it at the centre with a tack.

Adjust the strip so that it is parallel to the door and secure it with tacks at 30mm intervals.

Some have brushes instead of a continuous strip, and others have a mechanism to lift the strip as the door opens. These are much neater, though not necessarily more effective, than a homemade strip.

These generally come in standard sizes, and for internal doors the best arrangement is to use the brushpile type of strip. Here, the suspended bristles compress against the floor to forni an effective seal and are ideal with exposed plank, parquet or tiled floors.

2. The strip is fixed with pins or screws, but first you must adjust it for height.

Offer up the excluder so that when the door is closed, the fibres are slightly bent. This will give enough ‘play’ in the bristles to maintain a seal as the door is opened and closed.

Any strip of this type depends on contact for its efficiency — so there is bound to be some wear.

Strips such as these can wear quite quickly and for a long term solution, it may be better to tackle the sill and fit a readymade metal or plastic door sill which is fixed to the outside of the door. There are various types of these. Some are in one part which fixes to the sill with a springy seal that presses against the door. Other versions are in two parts, fitted to both door and sill so that they interlock.

The sprung weatherstrip used for sash windows can be used on doors. Offer up lengths of the strip to the door frame, the sprung edge facing in the direction the door opens, and mark the positions of the door hinges.

3. If the strip lies over the hinges, cut that small portion of it away, then tack the strip into place following the instructions of the manufacturers.
