Seal cracks and gaps around windows, doors, tubs and sinks with our broad selection of caulking products.

Caulk cracks and gaps to create a seal that will keep air, water and bugs out. Caulking can be used to seal a shower, tub or sink, weatherproof a door or window and install crown moulding. If it's a small project, caulking in a squeezable tube is easy to use. For larger projects, you'll want to use a rigid tube and caulking gun. For best results, it's a good idea to scrape away old caulking or use caulk remover. This way, you start with a clean surface and achieve a proper seal.

Common types include latex (also called painter's caulk) or silicone caulk. There are also specialty caulks such as concrete caulk to fill gaps in driveways and sidewalks, and caulks for use with windows, tubs, roofs and more. Before beginning a project, you will want to make sure you choose the best type for the job. When selecting caulk, also consider the colour. Some caulks are paintable, so you can use white and paint it to match the surrounding area. Otherwise, choose the colour closest to the area and create a seamless, professional finish.
