Why is caulking important?

Caulking helps to prevent water damage in your home, which can lead to mold growth, rotting, and other forms of cosmetic or eventually structural damage. Caulking also helps to keep humid air and dust from penetrating the siding or entering your home, which can reduce your energy costs and improve indoor air quality. Furthermore, caulking can help to prevent pests from entering your home, which can save you from costly extermination fees.

When should you caulk?

It is best to caulk your home once a year, or as soon as you notice any cracks or gaps. This can be done in the spring or fall, when temperatures are mild, to ensure a proper and long-lasting seal. It is also important to caulk any new construction or remodeling projects as soon as they are completed, to ensure a tight and sealed home.  If you are installing interior MDF millwork, it is important to caulk and paint as soon as possible.

How to caulk:

  1. Prepare the area: Clean the surface and remove any old or damaged caulk with a caulk remover or a putty knife. Wipe down the surface with a damp cloth to remove any residue or dust.
  2. Cut the tip of the caulk tube: Cut the tip of the caulk tube to match the width of the gap or crack you are sealing.
  3. Apply the caulk: Hold the caulk gun at a 45-degree angle and apply the caulk in a continuous, steady motion. Move the gun along the gap or crack, filling it completely with caulk.
  4. Smooth the caulk: Use a caulk smoothing tool or your finger to smooth the caulk and remove any excess. Make sure to wipe your finger frequently with a damp cloth to prevent smudging the caulk.
  5. Clean up: Clean any excess caulk or smudging with a damp cloth.
