Door Threshold / September 18, 2018 / Pauline Francoeur.
I would like to recommend something here for anyone who is thinking about installing a door that will have a high door threshold. Dont do it unless you have another reason that is protecting the area from water snow or something else that would create a bigger problem if you lower the door threshold. Heres what happens to most people. You walk through your home regularly travel about and even go to work without running into these high door thresholds. You come home and subconsciously youre not even thinking about the raised curb and you trip. One trip to the ground could cost you more in medical bills than it would have been to remove and lower the raised door threshold.
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.
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. It is a truly green product that uses recycled cardboard for the door protection with natural rubber bands for attachment. Another popular protector is the 1-2-3 Doorshield product. This protector is not recyclable as it uses plastic Velcro for the door attachment.
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.
