What can I do about gaps in the bricks of my home's exterior?

I am worried about water seeping in and causing more damage.

Use a stiff brush to clean gaps in brick. Mix a small batch of mortar according to manufacturer's instructions. Dampen the section (3 ft. x 3 ft) of brick to be repaired.Use a trowel to fill vertical gaps with mortar then fill horizontal gaps. Smooth the new mortar with a finishing tool called a brick jointer. It's that easy.

These gaps should be sealed to ensure the watertight exterior. You can seal them with mortar mixed to match the current mortar, or your can use caulking.

You can inject an acrylic product into the seams with a chaulking gun. Make sure to use a high quality product that is sturdy and flexible.

I have sealed my exterior brick with Thompson's water seal. It is very easy to apply. I used an empty weed killer spray bottle filled with the water-to-sealant mixture as per the manufacturer's directions. Once the sealer has dried, the brick surfaces seem to have a slight sheen to them.

For small gaps, a bit of putty, for medium to large gaps, there is a type of mesh you can buy with the putty to seal them.
