Maintaining a fixed window—one that doesn't open—is often overlooked because there are no moving parts to break. However, the seals around these windows are your home's primary defense against drafts, moisture, and skyrocketing energy bills. Over time, exposure to UV rays and temperature swings causes even the best sealant to crack, peel, or shrink.

- Clean the joint with a rag and solvent; allow to dry.
