Tightly wedged shims will allow you to operate the door carefully. Open and close to check the door touching the weather stripping evenly top to bottom for any possible jambs twist. Adjust as necessary even though jambs may not flush with plaster top to bottom. A good carpenter wont assume the original door was installed correctly right? Check the brickmold reveal you should have consistent and even measurements side to side and top to bottom. Its unusual to have brick out of plumb to any great extent. Adjust shims again as necessary. Index the jambs in the rough opening and the shims to jambs with pencil for reference when installing the system permanently. Remember you only have one chance to get this installation right so be patient - you will be rewarded with a satisfying outcome.
Many exterior door thresholds have bottom plates. These plates allow the door to seal but can be difficult barriers for scooters and wheelchairs. The tracks on sliding glass doors can be significantly damaged if a scooter runs over them. These are just a few example of the need for threshold ramps. They can help you overcome barriers and make getting around easy. These ramps are sold in a variety of shapes sizes and materials. They can be custom fit for your home or business. They are also designed to be non-skid and provide good traction. This prevents slips or slides.
The cost to protecting doors jambs and thresholds are well worth the small investment. The average cost for a cardboard door protector one cardboard jamb protector and tape for the threshold is less than 25.00 The cost to replace just a door alone can range from several hundred dollars to several thousand dollars. In addition many door protectors and jamb protectors are reusable so the long term cost for protection is even less. Experienced contractors recognize the importance of protecting the entry doors jambs and thresholds. Doing so is a great way to increase customer satisfaction and keep job site damage to a minimum.
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.
These protectors can be made from molded plastic or cardboard. Pre-molded plastic protection works well for jambs with standard door casing widths. For larger jambs there are several wrap-around jamb protectors that work similarly but are not molded to an exact casing size. These reusable protectors provide excellent protection however they are the most expensive jamb protectors in the market. Less expensive cardboard protectors wrap around jambs in a similar fashion and cost considerably less than their plastic counterparts. These are available from a wide range of manufacturers can be purchased online or in construction supply stores as well.
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.
