Door Threshold / September 15, 2018 / Leala Melanson
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.
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.
Garage door insulation is essential with wooden doors as you cannot allow any water to get in to penetrate the wood. You must have a high quality threshold sealant to help prevent rotting and severe damage to your door. The great thing about using wood though is that if it does endure wear and tear over the years it can be reconditioned without the need to replace the entire door. The most used type of door however is the steel door. You will see this one on most garages across America. Steel is extremely strong and robust and is impervious to rust. This gives you great peace of mind that the door will last for many years to come.
