Door thresholds continue h2o out. They also serve to seal the bottom of the frame to go along moisture from wicking upward into the frame, causing rot. Installing a threshold is usually a uncomplicated matter of driving screws downward through the provided holes into the threshold into the sill plate or wooden sill. When installing thresholds on concrete an extra step is added to provide pilot holes for the necessary concrete screws.

Remove the original threshold. If there are concrete screws in the original back them out with a drill to remove the threshold. Nigh thresholds on physical are nailed. Use a large pry bar and hammer to pry a nailed threshold abroad from the flooring. Start at one end and pry advisedly to avert chipping the physical. Work beyond the width of the door, tapping the pry bar nether the threshold and levering up to loosen the nails.

  • Door thresholds proceed water out.
  • Use a large pry bar and hammer to pry a nailed threshold away from the floor.

Remove the loosened threshold and use it every bit a template to cut the new threshold to length. A jigsaw or reciprocating saw is the best way to cut a metallic threshold. A fine-toothed blade on a round saw works well for wooden thresholds.

Marker the ends of the new threshold using the original as a pattern. The ends will be notched to fit effectually the door frames. The blueprint varies from door to door. Cutting the notches using a jigsaw for best results.

  • Remove the loosened threshold and utilize it as a template to cutting the new threshold to length.
  • Cut the notches using a jigsaw for best results.

Tap the threshold into place using a condom mallet or hammer and wood cake to avert impairment to the threshold. Practice non force information technology. If the fit is too tight, trim it slightly and attempt once more. Make needed adjustments until you take a snug fit.

Mark pilot holes for the concrete screws. With a 3/16-inch rotary mason's fleck, drill into the concrete underneath each spiral pigsty in the threshold. Drill to a depth of i/viii inch to mark the location. Remove the threshold.

  • Tap the threshold into place using a rubber mallet or hammer and wood block to avoid impairment to the threshold.
  • With a iii/16-inch rotary mason's bit, drill into the concrete underneath each screw hole in the threshold.

Drill a pilot hole in each location you lot marked in the concluding step using the same mason'due south bit. Make your holes 2-inches deep. Wrap a piece of masking record effectually the bit, ii inches from the tip to mark the depth. Blow the dust from the holes for a proper fit.

  • Drill a pilot pigsty in each location you marked in the last step using the same mason's bit.
  • Wrap a slice of masking record around the bit, 2 inches from the tip to mark the depth.

Set up the threshold back in place. Bulldoze a 2 ½ -past-1/iv inch concrete screw into each hole. Drive the screws until they are tight against the threshold. Do not over tighten. Caulk around the edges of the new threshold with latex caulk. Smooth caulking with a dampened finger for a shine finish.
