Door Threshold / September 16, 2018 / Marphisa Duffet.
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.
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.
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.
I believe installation direct to masonry is the height of challenge for an entry door where skills and patience for a carpenter are truly tested. You really only have one chance to get it right - screw hole mistakes in the cinderblock dont allow for incremental jambs adjustments. Here is where carpentry meets art you must think and be creative. So the satisfaction of a properly installed door in this case becomes at least for me a real thrill. On the initial site visit to measure up the door youre going to tap on the walls to see if they are drywall or plaster.
