Exterior Finishes – Brick, Siding, Stone, Fascia

The building process does not always occur one phase at a time. For instance, while the mechanical rough-ins proceed on the interior of your new home, exterior finishes progress concurrently. Foundations receive a water repellent coating, the installation of a curtain drain occurs, and exterior fascia begins.

Homes may receive a brick foundation with siding, or they may feature a mix of brick, siding and stone. If the exterior finishes on your home are predominantly masonry (brick and/or stone), watch for a few key items during application – weep holes to allow for airflow between brick or stone and wood on exterior walls, proper slant on door and window sills to allow for water shed, adequate usage of brick ties to hold the exterior finish to the walls, and appropriate sizing of lentils to support the weight of the masonry product you chose for your home.

Wall ties, weep holes, flashing

A one inch to two inch cavity exists between the brick veneer wall and the framed wall. A brick tie holds the brick veneer to the wall. This is a thin piece of metal, approximately eight inches long and one inch wide nailed to the framed wall every 16” horizontally and vertically. If you use a queen-sized brick, insert brick ties at least every five courses. Note that brick comes in many different sizes, and the amount of brick, brick ties, mortar, and sand required will vary depending on the size of the brick you select for your new home.

Ventilation between the brick veneer and the framed wall allows moisture to escape and keep your home dry and sound. Weep holes placed around your foundation and over windows and doors allow air to circulate and keep the interior framed wall dry. While a mason builds the brick veneer, he can easily apply cotton cording from the wall through the mortar joints which will create a cavity for moisture to wick away from the brick.  The application of stone veneer also requires the same ventilation and flashing that brick veneer employs.

A wide variety of siding products might be used on the exterior of your home, and those products may be aluminum, vinyl, or masonry in nature.  A popular product that became available a few years ago, manufactured by James Hardie, is a fiber cement siding called Hardie Plank.  These products do not require special consideration to allow for air circulation between the veneer and the framed wall, and come in a wide variety of styles and colors.
