If you’re buying a home in Arlington, TX, you may notice cracks in the exterior brick. That can feel alarming at first. But are they normal — or signs of serious structural trouble?
The answer depends on the type of crack and what’s causing it.
Why Arlington TX Brick Cracks Are Common
Many exterior brick cracks Arlington homes experience are related to North Texas soil conditions. Arlington sits on expansive clay soil. This type of soil expands during wet spring months and shrinks during hot, dry summers.
In March and April, heavy rain can cause the soil to swell. During extreme summer heat, the soil contracts. This constant movement puts stress on foundations and brick veneer, often leading to visible cracking.
This is why Arlington TX brick cracks are common — but not all cracks are equal.
What Normal Brick Cracks Look Like
Some cracking can be cosmetic and expected over time.
Hairline cracks in mortar joints are common in both older homes and new builds. Small vertical shrinkage cracks may also appear as building materials naturally cure and settle.
These cracks are usually thin, consistent, and not widening. They often don’t indicate immediate structural foundation concerns Arlington TX buyers should worry about.
However, distinguishing between cosmetic settling and structural movement requires careful evaluation.
When Brick Cracks May Signal Structural Issues
Certain patterns deserve closer attention.
Stair-step cracks following mortar joints diagonally across brick can indicate foundation movement. Cracks wider than 1/8 inch, gaps that continue to grow, or cracks paired with sticking doors, uneven floors, or interior drywall cracks may suggest deeper structural foundation concerns Arlington TX homes sometimes face due to soil shifts.
After long dry summers, fall is an especially important time to evaluate brick conditions before winter moisture returns.
Why a Home Inspection in Arlington, TX Is Critical
A professional Home Inspection in Arlington, TX helps buyers understand whether brick cracks are cosmetic or signs of structural stress.
During a full home inspection, visible foundation indicators are evaluated, including exterior brick patterns, grading, drainage, and interior movement symptoms. This evaluation is visual and non-invasive. It is not a structural engineering assessment. If significant movement is suspected, further evaluation by a licensed structural engineer may be recommended.
For homebuyers, this step provides clarity before closing — helping reduce fear of hidden issues and costly surprises after purchase.
Surety Home Inspections emphasizes pre-purchase inspections and thorough foundation evaluation during every home inspection Arlington TX clients schedule. The goal is not to alarm buyers, but to educate them so they can make informed decisions.
Frequently Asked Questions About Exterior Brick Cracks in Arlington, TX
Are exterior brick cracks normal in Arlington, Texas homes?
Some exterior brick cracking can be common because North Texas clay soil expands during wet periods and contracts during hot, dry weather. Thin, stable cracks in mortar joints may be cosmetic, but the crack pattern, width, location, and related conditions should be considered before deciding whether the movement is minor.
What types of brick cracks may indicate foundation movement?
Stair-step cracks that travel diagonally through mortar joints deserve closer attention. Cracks that are widening or accompanied by sticking doors, uneven floors, separated trim, or interior drywall cracking may also indicate movement that should be evaluated further.
How wide is too wide for a crack in exterior brick?
A crack wider than approximately one-eighth of an inch generally deserves closer review, especially when it continues to grow or appears with other signs of movement. Width alone does not determine the cause, so the surrounding brick, foundation, grading, drainage, and interior conditions should also be evaluated.
Can heavy rain and drought cause brick cracks in Arlington homes?
Yes. Expansive clay soil can swell after heavy rainfall and shrink during extended dry weather. These moisture changes can place stress on the foundation and brick veneer, which may contribute to visible cracking around the exterior.
Can a home inspector tell whether a brick crack is structural?
A home inspector can evaluate visible crack patterns and related conditions such as grading, drainage, foundation indicators, uneven floors, and interior movement. However, a standard home inspection is not a structural engineering assessment. Significant or uncertain movement may require evaluation by a licensed structural engineer.
Should I buy a house in Arlington if it has exterior brick cracks?
Brick cracks do not automatically mean you should walk away from the home. Review the inspection findings, ask whether additional evaluation is recommended, and obtain professional opinions or repair estimates when appropriate. You can then consider the severity, repair scope, cost, and your options under the purchase agreement.
