Prehung Exterior Door Threshold Has Gap Between Concrete Floor

But a gap of 1 5 inches seems excessive.

Prehung exterior door threshold has gap between concrete floor.

I recently installed a new metal exterior door between my garage and basement. Length is custom cut to size. The new threshold should have a similar profile to your old threshold and be 1 to 2 inches longer than the length of the doorway so that you can cut it for an exact fit. Most entry door frames have a piece of lumber below the door and combined with the metal threshold will raise the base of the door.

Support for an aluminum threshold when i install an exterior prehung door i pull the oak sill along with the old frame i replace it with a piece of pt 2x8 that gets leveled in both directions these doors are designed to sit on the plywood of a deck framed house but older ballon frame homes have the oak saddle sitting directly on sloped. The installer told me the shoe would cover the gap. Residential adjustable height thresholds ensure a tight seal for beneath the door gaps despite uneven door bottoms and sub sill level changes. Available in aluminum mill finish and three anodized finishes.

I ve just paid a series of professionals to measure order install and paint a pre hung exterior door. Run a bead of high quality sealant along the exposed framing where the new door s exterior trim will meet the wall and across the floor where the door s threshold will sit. Mark the new threshold based on your measurements. While these measurements would appear to make sense they can create a major problem.

Door thresholds come in a variety of materials such as wood marble and metal and make the transition from doorway to floor smooth and easy. Measure between the outside edges of the door casing. The concrete floor was very crooked so after installation there is about a 1 2 gap at one end under the sill plate that was attached to the door. The solid wood base has an all aluminum exterior for superior stability and long lasting reliability.

Carefully measure the doorway for the new threshold. In the case of a home that has floor joists and a sub floor the rough in opening will be measured from the top of the sub floor.
