112 and 312 Sill Replacement

Some models of the 112 and 312 style casements have had issues with the sills rotting. These are replaceable simply by cutting out the old sill and inserting a new profiled sill that has  a better profile to accept a new designed sill weatherstrip.

Please view the photo's to see the steps in the process and view the new sill that is secured with construction grade sealants and adhesives.
