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.
The front entryway including the door jambs and threshold is the focal point of your clients home. It sets the tone and expectation for the rest of the home and it can add or detract curb appeal. Entryways have been important dating as far back to the Greeks. According to Jesse Nevins of Coastal Carolina University "To ancient Greeks doors were considered sacred and surrounded with superstition. So much so that doors and the comprising parts had their own deities. For the Greeks a door was not simply a way to enter a building but a holy place itself worthy of the highest respect." Keeping doors jambs and thresholds looking great while a home is under construction or remodeling is important and is now easier than ever.
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.
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.
