Use a high-quality caulk with silicone around your windows, as it’s waterproof and shrink-proof. Or, you can use a caulk consisting of polyurethane or acrylic if you want to be able to paint over it. Caulk made from silicone is not paintable. Avoid using inexpensive caulk that has a resin or oil base. These caulks will not last long and may shrink and pull away from the window as temperatures go up and down.

On average, bay windows are three times as expensive as a standard double-hung window, so up-front cost is a major drawback. They also let in more natural light than most other types of windows, which can be a positive thing, but it can also lead to more aggressive fading and UV damage to furniture and flooring. Larger windows allow for more heat transfer, so bay windows tend to be less energy-efficient due to their size. Finally, window treatments for bay windows can be more challenging to find, and they’re more expensive than those you’d place over standard-sized windows.
