Luckily, fixing a window seal is a workable DIY task for many house owners— if they know what to search for and how to continue.

• For gaps larger than ¼ in, consider using backer rod (foam rope) before using the sealant.

7. Tool the Seal

• Utilize a caulk‑tooling tool or a wet finger (dipped in soapy water) to smooth the bead and guarantee excellent contact with both surfaces.
• Remove the painter's tape right away after tooling to prevent raising the fresh sealant.

8. Allow to Cure
