How To Fit A Weatherboard

FITTING A WEATHERBOARD

Weatherboards are set along the bottom edge of a door to deflect rainwater running down the face and stop it seeping underneath. If you don’t have one, or your existing one is in poor condition, it’s worth fitting a new one. The bottoms of doors are rarely painted, and are easily affected by damp.

How To Fit A Weatherboard Traditional weatherboards were flat pieces of timber with bevelled edges, screwed or nailed at an angle to the bottom rail of the door, They are quite flimsy, and easily damaged.

The modern version is a substantial moulding, screwed or tonguedandgrooved in place. A ‘drip groove’ underneath stops water seeping back.

You can buy a length of weatherboard moulding from your local timber supplier.

To fit a weatherboard, start by measuring the distance between the door frame stops and cut a length of weatherboard moulding to size.

Trim both ends to curve inwards towards the front to prevent the weatherboard sticking against the door stop when the door is closed. Then prime the back and underside of the mouldings as you won’t be able to reach these later.

1. Next mark the position of the weatherboard on the front of the door and continue this line round to the back.

2. Then drill screw holes straight through the door from the back.

Position the holes so that the screws enter the board at its thickest point.

3. To prevent water finding its way behind the weatherboard, apply some non-setting mastic around the edge of the mating surfaces.

Fit the board while this is tacky to ensure a good seal.

If you don’t have any mastic, the remains of a can of oil-based gloss paint make a handy substitute.

Insert the two end screws first; when they begin to bite into the weatherboard, stop and check the door for easy opening and closing before you insert and tighten the remaining screws.

Finish the weatherboard to protect it and to match the door. Cover the screw heads with filler before priming and painting or varnishing.
