How To Fix That Leaky Door!
Recently I have been to two customers houses to look at “leaky” exterior doors. One of these clients actually thought and was prepared to replace the door at a cost of $3200.00. Turned out that both of these doors needed new weather seals installed.
Installing door weather stripping is fairly straightforward and many people do not realize that a lot of the newer doors [20 years or less] and windows all have kerf-in weather strips that CAN be replaced. Over time the weather, sunlight and compression all take its toll on the weatherstripping and it looses resiliency. Both of these doors that I looked at were in real good shape, were decent quality exterior doors and were around 15-17 years old, way too soon for a costly replacement!
Kerf-In Weatherstrippinig
Both doors had kerf-in weatherstripping which is the most common seal you will find in new doors these days because it works well and is easy to install and replace. 
These weather strips can be bought at most hardware stores for under $30.00, or ordered from the door manufacturer.
