    Replaced old rotted sill perfectly

  2. Jim Acri

    Good product. Quality built. Easy to install.

  3. David Susan

    This was the perfect product to replace the rotted sill on the side door of our house.

    The blue and orange big box stores can’t compete with those cheap thresholds that they sell. Just about every one of them has a wood component that is bound to rot with any moderate exposure to moisture. Not only does the composite component of this product offer rot resistance due to the inorganic nature of it, it makes for once study filler that I could jump up and down on all day without breaking. Add the adjustment feature and you can fit this in any doorway without having to worry about the longevity of the threshold.

  5. Mark Laurent

    Quality product and quick shipped. The only way to go if I have to replace an another exterior threshold.

  6. Gene Milford

    Replacing a rotted sill. Disappointed with the size of the text on the instructions. Couldn’t find a larger print of the instructions on line either. I think the product will last, if I got the install correct. It appears that the intent to secure the sill to the floor is to rely on some basic caulk and wedging it under the door frame. Can’t go with that. Needed a little trimming to fit properly, but what doesn’t. Expecting long life.

  7. Laurence Hendrick

    Very high quality piece, looks great and should last a long time. I combined the sill with new casing frame savers so the install was relatively easy. One issue: the removable adjustable cap is a bit too high for my existing door which is steel and not easy to cut down. Not sure if I can ever fit the sill with cap under the door. Has to reuse the original sill for now. Will search for a solution.

  8. Chris Marino

  9. MikeP

    I installed this last year to replace a beat up old threshold that was probably decades old. Now that I’ve gone through all seasons with this installed (Northeast US), I can safely say that there’s no rot, mold or degradation of any sort. It’s a solid product and doesn’t flex or warp. It’s definitely worth the cost.
