Door Threshold / September 12, 2018 / Ambra Daoust.
Ive learned by the hard way of experience that its necessary to remove old existing jambs carefully. If directly fastened to masonry with cut nails jambs removal may break out the cinderblock unless the jambs are cut into short manageable lengths. An out of level concrete threshold step can be ground flat by a concrete cutting subcontractor or the door threshold can be adjusted by unscrewing and repositioning in the jamb by the amount out of level. Any attached brickmold and casing must be removed from the jambs to make installation easier with shimming. Also brickmold will probably have to be ripped in width to fit the overall brick opening width and height.
During construction contractors will pass through the doorway with materials and equipment needed for the construction project. Each pass risks scratching or denting the home entryway. Temporary protection should be in place prior to the start of construction and should include protection for all the aspects of the entryway. Doors can be protected with temporary cardboard door protectors available from a variety of manufacturers. Several protectors are not only made from recycled cardboard but can be reused and recycled entirely again making these protectors truly green. The first protector to market and most popular is DoorGuard.
What is a high door threshold? This would be any doorway that has a threshold that you have to step over or a threshold that is higher than the surface you are walking on. These safety problems are obvious the high door thresholds are a trip hazard and for elderly people can be difficult to step over. Handicapped people in wheelchairs or motorized scooters wont be able to access these areas unless there is an alternative doorway that provides access for their wheelchairs. Usually the high door thresholds are located in a garage where someone has either made a mistake during new construction or simply figured that it would be easier to install the door a little higher and to remove the concrete foundation footing to install the door properly.
Several sill manufacturers provide plastic threshold protection that is specific to the model of sill they are selling. Unfortunately heavy duty plastic protectors are not available for every type of entry threshold so the protection is not easy to obtain. There is one surface protection company on the west coast that does inventory plastic threshold protection for two of the most common sill profiles. For protecting sliding door tracks there are two types of threshold protection. The first is a hinged plastic protection that flips over the tracks of sliding doors to keep them clean from debris.
