Replace interlocking weatherstripping

[elismith]

New homeowner here. Looking to take on restoring a whole bunch of double-hung sash windows. The current windows have zinc interlocking weatherstripping. Upon an initial inspection, some appears to be in better shape than others. A lot of the kerfing appears to be deteriorated. I am looking into replacing this weatherstripping with spring bronze so I can avoid dealing with repairs to the kerfing.

Is this swap-out of weatherstripping types a reasonable thing to do? Would I have to do anything to fill in the existing kerfing on the windows if I replace with spring bronze?

Thanks for the advice,
-Eli

Kilian Hardware stocks both the interlocking and spring bronze. I'd personally replace the interlocking with a similar profile interlocking bronze weatherstripping and use spring bronze on casements and around doors.

Eli, welcome to the District. Kilian hardware as Colonial mentioned is the place to go for your spring bronze. The replacement shouldn’t be a hard job.
