Hi all! Can someone explain the difference between caulking and sealing? When should each be used, and are there specific products that work best for different situations, like around windows, doors, or cracks in siding?

Hi Downaski!
Caulking and sealing are often used interchangeably, but they have some key differences. Caulking is typically used to fill gaps, cracks, or joints to prevent air, water, or pests from getting through. It's more flexible and is commonly used around windows, doors, and baseboards where movement might occur. Silicone caulk, for instance, works great in bathrooms or kitchens because it resists water and mold, while acrylic latex caulk is ideal for painting over around trim or siding.
Sealing, on the other hand, generally refers to applying a product to cover and protect a surface. Think of it like a shield—it’s used for larger areas to make them water-resistant, airtight, or stain-resistant. Sealants are often applied to concrete, wood, or tile surfaces to prevent moisture damage or stains.
For your specific examples, around windows and doors, caulking is the go-to to close gaps. For cracks in siding, a flexible outdoor sealant might be better since it can handle exposure to the elements. Do you have a particular project in mind?

Thanks for breaking that down! I didn’t realize how much versatility silicone caulk has, especially for kitchens and bathrooms.
As for projects, I’ve been thinking about sealing up some small gaps around my windows and maybe tackling a couple of cracks in the outdoor siding. Do you have any favorite products you’d recommend for outdoor sealants? Also, how often do you usually reapply caulk or sealant in areas like these?
Would love to hear your tips!
