Front Door Threshold Transition to Hardwood Floor

    I have finished my 3/4" hardwood up to 1/2" from the front door threshold and adjacent drywall. How does one finish off the last 1/2" - with threshold moulding?

    1/2" seems a bit far from your sheetrock, your base must be pretty thick. You will probably be most happy making a custom threshold to cover the space to your door.

    It is possible the manufacturer's instructions were followed. Some folks like the look of baseboard combined with base shoe. I probably would have undercut the sheetrock, but I don't care for base shoe unless the baseboard is of the taller variety, say 5" plus, in which case the baseboard is usually thicker as you mentioned.

    I agree with the custom threshold peice.

    If your only looking at the threshold you could probably cut to fit and liquid nail in place all depends on which direction you placed the tung.

    I followed manufacturers instructions and left 1/2" all around for expansion. I assumed that was also needed at the front door entryway which would likely experience the greatest environmental variations.

    The hardwood floor runs parallel to the door. The tongue would be facing out but the last piece was cut to allow for the 1/2" expansion gap. The base is 7 1/2" high x 9/16" thick and shoe mold will also be used. Thus the gap along the drywall on either side of the door frame will be easily covered. The problem is the 1/2" gap along the door and side lights.

    I could take out the last piece and cut a new one to fit but I don't see how that would leave room for expansion. Some mentioned a custom threshold. What would it look like? Would it sit higher that the rest of the floor? I'm envisioning something L-shaped that goes over the top of the last run covering and extending beyond the expansion gap.

    If you are using shoe mold, (true shoe ) it is 1/2" x 3/4", cut a piece to cover the area and lay it down so the 3/4" side covers the gap.

    I have done that may times, and know it works. In your case install using the wide side on the floor.

    Shoe Mould: Used to cover gaps between baseboards and flooring, this is a quarter round molding milled with one flat edge wider than the other. Install the molding with the shorter edge against the floor.

    I'm a little confused as to why you're not taking out the existing threshold and either raising it/adapting it to the new floor or replacing it with one that's compatible------covering the appropriate expansion gap and protecting the floor from the elements.

    Usually you can find something that works at a lumber yard, flooring supply store, where ever it was you bought the flooring or just a plain old hardware store.

    If not, as others mention you can customize a piece of oak or matching hardwood or have a carpenter/millwright make one to your specific design.

    most likeky an exterior door where jamb and threshold are all one unit...

    how much clearance do you have between bottom of door and to p of hardwood? and is the door jamb and threshold all one unit?

    Thanks for all the interest and suggestions. As nimrod thought the jamb and threshold are one unit and flush on the inside. Since we replaced old 3/8" engineered floor with 3/4" solid, the clearance between door and floor is limited at just over 1/4" inch. I found a piece of overlap threshold where the overlap is slightly over 1/4". I am hopeful that I can make this work unmodified. If not, I think I can modify it to work or use an extra piece of flooring and make something work on the table saw. Again thanks all.

    "All one unit" doesn't mean it has to stay that way. You jumped the gun by not planning for the transition, but it's not too late to fix it. Just a little harder, that's all. ;)

    Exterior doors should have much more clearance than a quarter inch. Most people like to be able to put a wipe-off mat inside the entrance doors. You can't do that with only a quarter inch clearance.

    If it were me, I'd cut the existing threshold out flush to the sides of the door casing. Your door won't fall over or break in any other way. Install a new threshold, shimming for height as necessary with exterior ply and metal flashing to protect from water incursion. Cut door to fit.

    Now you can finish the new flooring to the new threshold. You must fashion a transition trim and leave an expansion gap under the trim for the hardwood. Your half inch won't cut it.

    Best of luck,

    It's possible to put a threshold over an existing threshold with a little thought and planning.

    This is a pre-hung outside door. The bronze color for the additional threshold was chosen since the view from the inside was deemed the best option. This front door is almost never used.

    The existing threshold had grooves across it's width as you can see. The groove nearest the top of the old threshold made the perfect resting place for a strip of 3/8 by 3/8 angle aluminum to support the outside edge of this newly added threshold. This strip of aluminum allowed the new threshold to lay flat/level with the new flooring. Installing one on top like this means that it will overlap onto the new flooring 3/4" to 1"

    I recall this new threshold to be 5/8" tall and was a standard width threshold............. tho it looks narrow in the image.

    the newer all one unit doors are usually metal or metal clad doors. I would never remove threshold and try to cut door. BIG can of worms.....:ohno:
