Questions & Answers

My door currently has 1/2 inch weather stripping. If I replace with this 1" weatherstripping, will the door still close properly?
ByOct 18, 2026
1 Answer | 
Answer This Question

It will close a little tighter when you replace the old kerf. It should be fine.

    is door frame insulation strip, glued in or nailed in?
    ByAug 12, 2026
    1 Answer | 
    Answer This Question

    This is not glued or nailed in. It fits into the channel meant to hold the kerf to the door stop.

        Does this come as a vertically extended piece or does it ship rolled up?
        ByJun 24, 2026
        1 Answer | 
        Answer This Question

        In the store it is vertical. When shipping one or two pieces, it is curled to ship.

          Is this a lifetime insulation or how often does it need to be replaced
          ByMar 16, 2026
          1 Answer | 
          Answer This Question

          No, it does not have a lifetime guarantee. Depending on the use of the door, and if it is subjected directly to the elements, it could last 4 to 10 years. We guarantee it for 1 year.

            If this 1" frost king kerf model was in the door, will the elite frost king model that is 3/4" with a lifetime warranty work as a replacement? I don't see other 1" ones with long lifespans
            ByFeb 3, 2026
            1 Answer | 
            Answer This Question

            Yes it will work as replacement

              Will this work on doggy doors
              ByDec 13, 2025
              1 Answer | 
              Answer This Question

              Probably not since they usually don't have a channel to snap the kerf in place.

                It is 81" long, one piece. And yes, it takes 3 pieces to do one complete door.

                  This door seal was just what we needed. Easy to cut to length and it snapped right into place. The dark brown color matched our freshly painted front door perfectly!

                  Apparently, HD employs monkeys to pack & ship their products
                  Home Depot folded a 7 foot strip of kerf so that it could be shipped in a 13 inch box. The strip was damaged and could not be used. Why does a business list an item as available to ship to my home if that business has absolutely no reasonable intention of getting the product to the customer/consumer in good condition? Ridiculous.

                    This very inexpensive item exceeded my expectations. The quality seems just as good as the original piece that came with my door and install was quick and easy. I did it myself in about 3 minutes. If my dog destroys anymore ill be sure to order more of these

                    Was looking for weatherstripping to replace the one that came with the door frame. Found this one that worked out perfect. Was able to insert it t into the area where the old stripping was removed from. Does a great job of sealing around the door to keep bugs, heat and cold out. An inexpensive way to repair an old door.

                    Damaged in Shipping
                    I am rating five stars on the product. However, these were not available at my local store, so I ordered them for delivery. Unfortunately, the way they are shipped permanently kinks them in the middle where they are folded. I understand why this is since they are very long, but I would recommend pushing in person. I may have to exchange once they become in stock.

                      The 81-inch door seal had been bent 180 degrees in two places to fit into the cardboard box it was shipped in and was permanently damaged. I had to return it to the local Home Depot.

                      Very good product to use around an exterior door application. I removed the existing stops on the frame. I used screws to apply the new stops (1" X 2") and I could loosen and tighten to install the new weather strip (to be able to install the attaching leg on the vinyl and be able to create a kerf). Including the top door stop. I bent each end of the new W.S. around the corners at top of frame & applied stick on vinyl foam on header to finish off the weather stripping.
