Lime Based Mortar - Repointing with Lime Based Mortar
The most common mistake made when repointing a masonry building is to use Portland Cement - a modern building material.  Portland Cement is an inflexible material and is harder than the surrounding brick.  I am sure you have seen buildings in which the face of the brick is missing this comes from the frozen water not being able to escape through the mortar.

An alternative to Portland Cement is Lime Based Mortar.  We use deGruchy's Lime Works Mortar in our restoration projects.  They have several standard colors and if you send them a sample of your existing mortar they can match the color and type.  Their website is www.palimeworks.com.
