Step‑by‑Step Repair Guide
The following list describes the general process for a normal DIY window seal repair:

- Apply brand-new sealant-- Load the caulk gun, cut the nozzle at a 45‑degree angle, and run a continuous bead along the joint.
- Install weatherstripping-- Press the new strip into the groove, ensuring a tight fit without compression.
- Permit treatment time-- Follow maker recommendations (typically 24‑48 hours) before exposing to moisture.
- Test for drafts-- Light a candle and move it gradually around the window; any flicker suggests air leak.
Tools and Materials Checklist
- Sealant: Silicone (for outside), polyurethane (for high‑movement joints).
- Weatherstripping: Self‑adhesive foam tape, V‑strip, or EPDM rubber.
- Caulk weapon-- Manual or pneumatic.
- Putty knife-- For eliminating old product.
- Security glasses and gloves-- Essential for security.
- Energy knife-- For cutting sealant and trimming old seals.
