Easy Process To Replace A Rotted Threshold Over Concrete
Wooden thresholds composed of red oak or other hardwoods are susceptible and prone to moisture that can rot the threshold with the passage of time. As soon as the threshold gets rotted, dust, debris, as well as water find a way underneath the door. Thresholds installed on concrete are extremely easy to replace, due to the reason that the concrete doesn’t rot like typical subfloors. This, as a result, means the task is confined to the threshold unit. You will get hardwood, as well as aluminum thresholds, at door suppliers and most of the home centers.
Using A Hardwood Threshold
- Remove The Screws: First of all, keep the exterior door fully open before removing the screws from the rotted threshold, 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 threshold and concrete. Strike the end of the chisel with the help of a hammer in order to dislodge the threshold 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 threshold in place. Calculate and mark the new threshold. Square the mark with the help of a builder's square. Trim the threshold with the help of a circular saw or handsaw.
- Mark Locations For The New Screws: Put the threshold 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 threshold. 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 threshold 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 threshold 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.
Using An Aluminum Threshold
- Remove The Rotted Threshold: Perform the first three steps mentioned in the above section in order to get rid of the rotted threshold as well as any residual sealant from the concrete.
- Mark Your End Points: Smoothly move the rubber seal out of the channel in the threshold to uncover the manufacturer's screw holes. Place the aluminum threshold in opposition to the outer edges of the door jambs so that the holes in the threshold are 1 inch either way of the existing concrete anchors. Mark each end of the aluminum threshold at points that line up with equivalent inside edges of the door jambs with the help of a felt-tip marker.
- Drill Anchor Holes: Trim the threshold at the marks with the help of a hacksaw. Place the threshold at the opening with the inner edge in opposition to the edge of the flooring or carpet strip. Use the manufacturer's screw holes as a lead and drill 1 1/2-inch deep holes for anchors in the concrete with the help of a drill and carbide drill bit. Put the threshold on one side.
- Install The Anchors: Push 3/16-inch concrete anchors into each hole in the concrete. Put or spread a uniform bead of exterior silicone sealant through both the edges at the bottom of the threshold.
- Install The Threshold: Put or arrange the threshold in the opening. Push the provided screws at each hole and into the equivalent anchor. Again fit the rubber seal into the channel on the threshold. This can be done by squeezing the edges together at one end, before inserting that end into the channel and release your grip. Do this at several points in order to fit the seal into the channel.
