Door Threshold / September 16, 2018 / Marphisa Duffet.
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.
But what about retrofitting a new entry door system in an older home built with cinderblock masonry walls? You cant use the same technique of just nailing through the jambs the masonry will just deflect and bend a regular framing nail. Cut nails might possibly work but the chances for jambs alignment adjustments are slim to zero while the chances of masonry cracks or half-moon hammer head marks in the jambs are almost a given. Masonry screws need to be started in pre-drilled cinderblock holes which can be drilled through the jamb but Ive never been satisfied with their holding power alone where the cinderblock is prone to crumble around the holes while adjusting screws and snugging shims tight. Experience has taught me to always insert plastic expansion sleeves in the cinderblock to properly fasten masonry screws.
Not only do threshold ramps allow entry for scooters and wheelchairs they also help prevent tripping injuries. These ramps provide greater and safer access for all. Rubber plastic and aluminum are the most common materials used in threshold ramps. Rubber ramps are commonly sold to clear heights up to three inches. They can be used indoors or outdoors and are durable. Rubber ramps can be cut and trimmed to customize the needed height or size. They work great for door thresholds and small steps with the capability to support the weights of up to 850 pounds. Ive always enjoyed installing residential entry doors.
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.
