Rated 5.0 out of 5.0 by Door seal Have a puppy that loves to scratch at the door have had to replace many times,this seal works great I can tell the difference when it is leaking and not, installs very easy and works great. August 29, 2014
Rated 5.0 out of 5.0 by Put an end to drafty doors The door seal was easy to install and did an excellent job of sealing the door September 22, 2015
Rated 5.0 out of 5.0 by best product I can find! This door seal is the best I can find. Creates a wide seal area, capable of sealing large differences in deflection, by which I mean it fits the contours of a warped door easily. As a general contractor, I highly recommend this product. Far better than any of the peel and stick garbage. June 25, 2013
Rated 5.0 out of 5.0��by Great but why only replacement kerf? This seal material stays supple and continues sealing well even in the coldest weather. I'm puzzled, though, why I can no longer buy it at Home Depot with the slotted wood trim piece so I can do custom sealing of doors and windows. January 30, 2014
Rated 5.0 out of 5.0 by Served my needs as described. Product was easy to cut and install, and it stopped the draft. December 7, 2011
Rated 5.0 out of 5.0 by Great DIY product Great fit, easy installation May 2, 2011
Rated 5.0 out of 5.0 by Easy to install, great value. My cat loves to destroy door kerf, so I keep some as back up too. Very easy to remove and replace. May 13, 2014
Rated 5.0 out of 5.0 by Great solution for an older door I have an older door with a wider kerf in the jamb. Just marry it with a screen spline [size .160] and ease in with a putty knife. It is removable for painting as well. I am a retired carpenter and found this tip from one of your customers to work very well. October 14, 2014
