Most entry door thresholds are manufactured from metal or a combination of metal and wood. Metal thresholds often have black anodized coatings that are easily scratched or dented. Wood thresholds can be stained scratched and dented as well. Some manufacturers have now manufactured plastic covers to protect their exact thresholds dimensions and include the covers with the complete door unit. There are other pre-molded protectors available from online suppliers of temporary protection products. There are also a variety of tapes that can be used for threshold protection.
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.
When youre satisfied that the door system is in the correct position drill through the thickest part of the hinge jamb with a regular drill at the hinges areas and then further drill into the cinderblock with a hammer drill. Drill the strike jamb in the same corresponding locations with the middle drilling positioned between the strike and deadbolt mortises. Countersink jambs holes to flush the masonry screw heads. It may be necessary to remove the door from the hinges for this step just remember to check the indexed jambs alignment to be sure nothing has moved. Remove shims and then remove door system from the rough opening. This must be done to install the plastic expansion sleeves into the holes drilled into the cinderblock.
This protection screws into a wood subflooring to hold it in place and thus cannot be used on sliding doors installed over cement slabs which are commonly used on the west coast. Another option that does work for protecting sliding doors installed on cement slabs is impact-resistant U-board protection. It is a thick heavy weight compressed paper protection that is made from recycled material and is completely reusable. The U-board is placed over the tracks while the door is open and protects sliding door tracks from dirt and grime. As with the plastic protector the Sill Pro keeps the sliding tracks clean and protects the tracks of the door from damage that can interfere with the working operations of the door.
With the rough opening clean and prepped for the new door and jamb move the system into place as one with door hung on hinges. Temporarily shim the side jambs tight top and bottom ends in the rough opening. Temporary shims at the bottom hinge may also be required to straighten door sag. The top hinge will sag just be aware that you will compensate for it later with shims and a screw to snug it when the door is installed permanently. Use of a level isnt necessary just align the jambs flush with the interior plaster and shift shims to square the door in the jambs with even spacing reveal.
Of course youre going to check the concrete threshold step for level. Carpenters never assume anything right? Measurement of the exterior brick opening overall height from threshold to lintel will be noted. Any further uncertainty about whether a house was built with masonry walls can be at least partly resolved by measuring the exterior brick opening overall width. A width measurement slightly off by about one-half inch from the nominal brick opening is a sure tip-off that youre going to be facing the direct fasten to masonry challenge. Adjust your installation estimate accordingly for some extra labor.
