Doorframes cost the price of the stock which is usually bought all rabbeted; smoothing, nailing up, squaring, and setting an inside frame will usually require about 1 1/2 or 2 hours. A common outside frame, with its casing and threshold, will require about another hour.

Two good men should build their scaffolds and put in place from 160 to 180 ft. of cornice per day, unless there are a great many angles. This includes all the work from the siding to the upper edge of the gutter bed, or to the place where the roof proper begins, and will require about 4 1/2 lb. of nails for 100 ft.

Another method is to figure the width of the cornice in inches, and allow 1 per inch in width to each foot in length in the length of the cornice; this will pay for all the material and labor of scaffolding.

In estimating corner boards and siding, the actual wall area is taken, and no allowance made for single openings, thus balancing the waste upon ordinary houses. To this should be added a fourth for the lap of 6" siding. If some form of matched siding is used, a third of the area should be added, as 4" siding will usually cover about 3 1/4" upon the wall, and narrow boards cut to waste more than wide ones. When the above method is used, there is no need of estimating the corner boards separately.

Two men should lay from 500 ft. to 700 ft. of siding, and use from 9 to 12 lb. of nails for a day's work.

Many contractors consider the cost of the labor of putting on outside finish as half of the cost of the material.

In estimating the material for flooring, add a fourth to the area for waste, not measuring stairs or other large openings. A room which is badly cut up by angles and curves generally should be estimated to its extreme dimensions, to recompense for the extra labor of cutting.

If a square-edged floor is to be laid, a fifth is sufficient allowance for waste.

From 2 to 3 lb. of nails per square are necessary to lay matched flooring.

A man should lay from 3 to 4 squares per day of matched softwood flooring of good material, blind nailed; if less than 4" wide, he should lay from 2 to 3 squares per day.

Of hardwood flooring, a man will lay from a fourth to a third less than the above quantities, and of a square-edged floor a man should lay from 6 to 8 squares per day.

Ceiling wainscoting, finished with cap and scotia, can be nailed and finished at the rate of from 2 to 2 1/2 squares per day upon ordinary straight work, using 2 lb. of 6d finish nails per square.

Panel work or dado may be set up (not made) and finished at the rate of about \\ squares per day, with an average amount of detail in the base and cap. No price can be given for the cost of paneled dado, as it can be made for almost any amount; the builder should obtain a figure from a factory before submitting an estimate.

It is usually safe to estimate a third more for the labor upon hardwood than upon softwood work.

A man should smooth, fit, and nail in place from 50 to 60 linear feet of three-member base per day, including mitering the outside and coping the inside angles, unless there are a great many.

It is a fair day's work to fit, hang, and mortise lock five inside doors; if rim locks are used instead, seven doors require about the same amount of work to fit the lock so that the door does not rattle.

It is about one hour's work to case around a door or window frame with a corner block and plinth casing; a mitered finish will require usually about one half more time. It is a common method to lump the mill work of a house and estimate the cost of the labor of putting it in place to equal one third or one half of its cost, according to the work required.

To fit, hang, trim, and put the stops on five windows, . will constitute a fair day's work. Many contractors figure the windows as finished complete, with blinds and painting, at $10 per opening, which is safe for an ordinary house.

Doors may be estimated by figuring the cost of the material and adding 1 1/4 day's work for an inside door, and 1 3/4 day's work for an outside door, if the latter is set with a hardwood sill and a thorough job is to be done. An inside door will require a good day's work to complete it, from making the frame to cutting down the threshold.

In the pantry, and other places which require shelving, a man should put in place from 60 to 75 ft. per day.

The cost of stairs varies greatly with the design, but it is usually safe to estimate that it will require one day's work to two and a half risers in height, if they are not too intricate in their design.

Box stairs usually require about one day's work to six risers in height.

A man should lay in place between 300 and 400 linear feet of grounds per day, straightening them up in good shape.

Mantels and other special woodwork are furnished sometimes by the carpenter. The owner often selects them himself, but the contractor pays for them, the owner paying any extra cost above the price allowed in the contract, which may be necessary to secure a special design to which he takes a fancy.

67. Plastering. - The material and labor required for 100 sq. yd. of three-coat work are as follows: -

1500 laths.

10 lb. 3d fine nails.

7 hours' work in making up mortar. 1 day's labor lathing. 12 bu. lime.

18 hours' work for two plasterers and one helper. 36 bu. sand. 8 lb. or 1 bu. of hair. 1/2 bu. plaster of Paris.

The custom of measuring for plastering varies, though the square yard is generally the unit. It is quite usual not to deduct single openings, and to measure only half of the double openings, treating the rest as solid wall. All strips less than 12" should be measured as 12"; for small closets add a half to the actual measurements. A man will lay about 1500 laths a day. Two plasterers and one helper will, upon ordinary work, build their stagings and do about 50 yd. per day of three-coat work. Roughly speaking, the plastering costs about 10 per cent of the entire cost of the house. Lathing and plastering vary in price according to locality from 20 to 25 for two-coat work, to 25 to 30 per square yard for three-coat work. In certain sections of the country, two-coat work is used exclusively.
