Preventing Rot on Exterior Door Jambs – Endura FrameSaver

  My company does about 50% of our business in whole house remodeling & 50% in new construction.  I really like doing both and I think that my experience in remodeling makes me a better new construction builder & vice-versa.  Here’s one example of lessons from remodeling affecting new construction techniques.

  When we do demo work on remodels we nearly always find rot around exterior doors.  Exterior doors can take a beating from the weather around the sill/jamb area and we often find the jambs completely rotted out.  Here’s a photo of a door pulled from a lakehouse remodel last year:

Pretty standard flush door with a small overhang overhead, the sill got wet every time it rained and the jamb was totally rotted after only 15 years.  This door was set on a concrete slab so there wasn’t subfloor damage but had it been on framing we would have seen even more adjacent damage from this water damage.  So, when I see this type of rot happening it really makes me think about using rot-proof materials & correct installation techniques.  
  On a current remodel project we have a side “man” door exiting from an attached garage.  The architect specified a flush painted door and the usual product you’ll see most often is a metal smooth panel door.  These do well in terms of rot but they dent pretty easily.  The first time you get hung up pushing the mower out the door it’ll dent that smooth metal surface.  I really prefer fiberglass doors and that’s what is in this video.  Also, check out the rot proof jamb.  Endura makes a wonderful product called FrameSaver that I tell my door supplier (BMC West in this case) to use and it comes to my job site ready to take the weather for the next 75+ years!  -Matt Risinger

  • Thanks for the Endura tip. We got away from all exterior metal doors several years ago and went to fiberglass also. We are a sea coast community and our problem was rust especially metal doors with glass inserts.

    Thanks again,

    What are your thoughts about using a casing bead around a flanged vinyl window? I’m in Texas and will applying a stucco clad. Will a casing bead help with water intrusion? Appreciate your thoughts.

    • I like the idea,as long as you have a head flash that lets the water above out. (uncaulked of course) Matt
