    Do I have to take the door off the hinges install the seal?

    Asked by Deborah January 19, 2018

    Answers

    I've installed several of this type. Your results will vary depending on the age of door/how many coats of paint it has received over the years. One thing I've found that can help is to not push the seal all the way up to the bottom of the door while sliding it on. That is, leave as much gap as possible between the bottom of the seal and bottom of the door, slide the seal into place, and once in position lever it up fully onto the door using a prybar or screwdriver.

    Do I have to remove old door seal first?

    yes. it'll work best if you can get an even edge along the bottom.

    That depends on the thickness of your bathroom door, it might look a little funny on an interior door. I don't think it would help much with noise, it's main purpose is for keeping out drafts. The rubber flaps on the bottom shouldn't hurt wooden floors, because they are pretty flexible.

    Will this seal keep bugs out?

    Do you have to remove door to install, or does it just slide on.

    It just slides on. You do need to press it with a little force as it is a snug fit. I did not remove the door. You can take a hammer with a cloth over it to tap and that will help slide it onto the door base.

    I am looking at this door seal and wodering if this would work on my 1 3/4 inch width door? Also ...

    Asked by Tena July 8, 2019

    Answers

    It will fit a 1 3/4" door but it is tight - make sure your door is exactly 1 3/4" - my door was 1.79" and I cannot get it to slide over it. It says it only seals gaps up to 3/4" - are you sure it is that big of a gap? That's a pretty huge gap to have between the bottom of your door and the threshold. This product just slips over the door so I suppose you could try to pull it down a bit but I don't think you could get it to close a gap more than 1" - maybe 1 1/4".

    Can you trim this down if you need it for a narrow door?

    Asked by Whit April 24, 2019

    Answers

    Yes - it is meant to be cut to size. I did not cut mine so I don't know exactly what it is like to cut but I would suggest a hacksaw or like the other guy mentioned a miter saw. I think a knife is likely to give you ragged results. Straight cut aviation snips might work well too if they are sharp and good quality.

    can this be cut for smaller doors

    Answers

    Yes, we had to trim a small amount for our back door, as well as the interior door leading to the garage, which are smaller. It was done on a table saw to pervent ragged edges.

    How is the thng attached to the door?

    Yes, I had bought this product before. The seal will wear in and then eventually need replaced again. That is standard for a door seal and depends on the amount of us the door gets.

    Incredibly easy install
    January 11, 2021
    I was skeptical based on no screws being required. It fits extremely well. I had to replace a seal that slid into a channel on the bottom of my exterior door. I could find nothing that fit the channel. So I decided to give this seal a try. First, simply remove the current seal. You do not need to remove the door to apply this new seal. Then measure the width of the door and cut the seal with a hacksaw or a Sawzall with a fine tooth blade. A razor blade will not work Cutting it a 1/16” short is far better than leaving it a bit long as the door will not close. You will need to hammer the seal onto the door as it is a snug fit. I cut a smalll block of plywood that was wider than the seal and placed it against the seal and then hammered the small block of plywood against the seal to avoid damaging the seal. Including cutting, this took me less than 10 minutes yo complete. I put this on two doord. Both are great!

    It broke in less than 3 months
    December 2, 2020
    AVOID. We installed this product in August and we just noticed a white strip under the door. The picture shows how trashed it looks: 3 strips of plastic are already broken. The one we had before lasted more than 10 years. I would expect a comparable durability, not just 3 months. We contacted customer support if MD products by email but we never heard back from them.

    The weather seal on the door from the mud room to the garage was damaged. The door is standard size so this replacement seal was a good fit. I trimmed the new seal to match the width of the door. I took the door off the hinges to make it easier to remove the old seal and install the new seal.

    (What's this)
    Easy but warped. This seal is designed to be slipped onto a door bottom and stay there with no need for nails, screws or adhesive. It slides on from one end to the other, but as I got to the last several inches, I needed to hit it with a mallet as it got very tight. My door is 1 ¾” wide and it fits nice and tight. It is true that it does stay put on the door by itself, however mine is warped. Mine curves up in the middle, and to get it to just touch the threshold, I did have to pull it down so the bottom has a space between it and the door bottom, so there is no way to straighten the warp unless I nail or glue it, or maybe make a filler piece of wood to slide into that space. The sides are 1 1/4" and 1 3/8" high on the outside, but much of that is a soft top flange and the bottom fins, not part of the hard gripping sides. The largest space you can put between its bottom and the door bottom is about ¾-1”. It has 4 rows of soft plastic fins on compressible pockets on the bottom that can fill between 1/8-1/4” space between the floor and the seal bottom. So I deduct if your floor is 1/4"-1 1/4" below the door bottom, this should fit. It has a very clean look, and if the door is white, it just disappears. The exterior of my door is a dark color and the white bottom looks ok on that. The storm door frame hides it from street view anyway. The bottom fins and top rubber flange are very delicate, and the outside ones ripped away at the ends just from trimming and installation, so I don't consider this a long-term solution, just temporary.
    Pros: Easy to Install, Stylish
    Cons: Not Durable, warped
