For any molded work which goes through the mill, the usual charge is 1 cent per square inch of section per lineal foot of the stuff from which the molding is made, as a base, from which is deducted a percentage, usually 40 to 60 per cent., depending on the grade of the material. For example, a 7/8"

(undressed thickness, 1 in.) door casing, 5 in. wide, will cost 1 cent X 5, less, say 50 per cent., or 2 1/2 cents per lineal foot.

Baseboard

The cost of material and fitting in place maybe estimated at 1 cent per square inch of section per lineal foot. This is for pine; if hardwood is used, double this price.

The same rule applies also to chair rails, cap rails, and natural-finish picture molds.

Paneling

This may be estimated at 12 cents per square foot for 1-inch pine stuff; if over 1 in., add simply for extra material. If the paneling is of hardwood and veneered, add 50 per cent, to price of pine.

Wainscoting

If plain, this may be estimated at 6 1/2 cents per square foot, the cap being figured separately by the lineal foot.

Door Frames

The following estimate represents the approximate cost of an ordinary door frame. This and succeeding estimates are given more to show how to make systematic and accurate estimates than to give any fixed prices.

Doors

The subjoined estimate gives the cost of a door of moderate price. If the door is veneered with hardwood, the cost is about 50 per cent, additional. A curved door in a curved wall costs about twice as much as straight work.
