How To Replace A Door Sill: Easy Process Of Replacing A Metal & Wooden Door Sill

Easy Process Of Replacing A Metal & Wooden Door Sill

The door sill, also known as a threshold, is the underside portion of your exterior door frame, which will help you keep the elements out & provides a seal, as well as a place to step when you are entering the home. These thresholds or door sills deteriorate with the passage of time, due to the reason that they have a great deal of foot traffic and exposure to the weather. Replace them as needed in order to help keep your home's exterior in great condition always.

Replacing Metal Door Sill

  • Measure The Existing Door Sill: First of all, calculate & evaluate the length as well as the width of the existing door threshold or door sill. After calculating the length & width of the door sill, buy a metal sill of the same size as well as shape.
  • Remove The Screws: Now, use a variable speed drill fitted with a screwdriver bit in order to pull out the screws securing the door sill firmly into place. With the help of a utility knife, trim through any caulk on the front as well as the back edges of the sill.
  • Place Pry Bar Beneath The Door Sill: Position the end of a pry bar underneath the door sill and pull up on the bar in order to remove the old threshold or door sill from the door frame. Place the new door sill out on a flat surface and put down the old one on top of it.
  • Trace The Shape Of The Old Door Sill Ends: With the help of a pencil, track down the shape of the ends of the old door sill onto the new one. The majority of the metal door sills are cut to adjust around the door jamb. Due to the fact that each door jamb can be different in size, the door sill must be cut on-site to fit.
  • Remove The Old Door Sill: Now, pull out the old threshold or door sill and screw the new door sill down onto a work table in order to prevent it from moving. With the help of a jigsaw, trim out the shape of the door jambs from the ends of the new door sill.
  • Seal The Door Sill Into Place: Finally, test the fit of the new door sill underneath the door and make sure the door closes over it. Screw the new door sill into place. Run a bead of waterproof caulk through the front as well as back edges of the threshold in order to help seal it into place.

Replacing A Wooden Door Sill

  • Remove The Screws: First of all, keep the exterior door fully open before removing the screws from the rotted door sill, with the help of a large flat-tip screwdriver.
  • Unseat The Threshold: Place, fit, or push the tip of a wood chisel betwixt the seam of the door sill and concrete. Strike the end of the chisel with the help of a hammer in order to dislodge the door sill from the concrete.
  • Remove Sealant With A Putty Knife: Move or push any uplifted concrete anchors flush with the surface of the concrete using the hammer. Get rid of any residual sealant from the concrete surface with the help of a steel putty knife.
  • Take Your Measurements: Now, calculate & evaluate the width of the door opening betwixt the inside faces of the door jambs. Subtract or take away 1/8 inch from a total for clearance in order to make it easier to slide the new door sill in place. Calculate and mark the new door sill. Square the mark with the help of a builder's square. Trim the door sill with the help of a circular saw or handsaw.
  • Mark Locations For The New Screws: Put the door sill in place at the door opening with the inside edge in opposition to the adjacent edge of the flooring or carpet strip. Mark a particular place or position for new screws through the centerline of the door sill. Mark positions 3 inches from each end as well as at 8-inch intervals in between.
  • Drill Your Holes: Put up a power drill with the help of a 3/16-inch carbide drill bit. Drill a single hole along the wood at each mark as long as the tip of the bit gets in touch with the concrete. Elevate or raise the door sill out as well as drill 1 1/2-inch deep holes at each drill tip mark on the concrete. Move or push a new 3/16-by-1-inch concrete anchor into each of the holes with the help of a hammer. The upper ends of each anchor should be even with the surface of the concrete.
  • Apply A Silicone Sealant: Put or spread a uniform layer of exterior silicone sealant on the concrete surface. Relocate the new door sill in position betwixt the jambs. Push a 3-inch stainless steel screw at each hole in the wood as well as into the corresponding concrete anchor below.
