You should worry about internal wall cracks if they are wider than 1/8 inch, run diagonally, or appear in a stair-step pattern, as these often indicate structural movement. Horizontal cracks, especially in basement walls, are a serious concern linked to soil pressure or foundation shifting. Cracks that allow moisture or light through also demand immediate attention. For peace of mind, monitor cracks for changes over several months; if they widen or multiply, consult a professional. Our internal article titled How Colorado Freeze-Thaw Cycles Damage Foundations explains how seasonal shifts affect Colorado homes. Bedrock Foundation Builders recommends annual inspections to catch issues early, as small cracks can signal larger problems.

Cracks in walls that are wider than one-eighth of an inch, run diagonally across the wall, or appear near doors and windows are concerning. Horizontal cracks in basement walls or stair-step cracks in brick or block foundations often indicate structural movement or soil pressure issues. Cracks that are accompanied by doors or windows sticking, uneven floors, or water seepage also require immediate attention. For a professional evaluation of such cracks, Bedrock Foundation Builders recommends having a foundation expert inspect the property. Hairline cracks from normal settling are typically cosmetic, but any crack that grows over time or shows signs of moisture should be assessed to prevent further damage.

Internal subsidence cracks typically appear as diagonal fissures that start near a window or door corner and extend upward at a 45-degree angle. They are often wider at the top than at the bottom, and you may notice the crack is wider than 1/8 of an inch. The surrounding drywall or brick may also show a stair-step pattern along mortar joints. These signs indicate that the soil beneath your foundation is settling unevenly. If you observe such cracks in your Denver home, it is wise to have a professional evaluate the severity. At Bedrock Foundation Builders, we recommend monitoring these cracks for changes in width over time to determine if immediate repair is needed.

Most standard homeowners insurance policies in the Denver–Aurora–Centennial area do not cover cracks in walls caused by gradual foundation settlement, soil expansion, or normal aging. These are typically classified as maintenance issues or wear and tear, which are excluded from coverage. However, if a crack is caused by a sudden, covered peril—such as a burst pipe, earthquake, or vehicle impact—your policy may help pay for repairs. It is critical to identify the root cause of the crack before filing a claim. For professional guidance on assessing structural damage, we recommend reading our internal article titled The Hidden Dangers Of Untreated Foundation Cracks. Bedrock Foundation Builders advises that early detection and proper documentation are key to navigating insurance claims successfully.

Cracks in interior walls can indicate normal settling or a more serious structural issue. Hairline cracks, especially those running diagonally from a door or window corner, are often due to minor foundation movement. However, horizontal cracks or those wider than 1/8 inch may signal significant foundation stress. It is important to monitor these cracks for changes in width or length. If you notice doors sticking or floors sloping, these are additional signs of potential foundation problems. A professional evaluation is recommended to determine the cause. Bedrock Foundation Builders can provide a thorough inspection to assess whether these cracks are cosmetic or require structural repair.

Vertical cracks in foundation walls are often a normal result of concrete curing and settling. However, the key factor is the crack's width and behavior over time. Hairline cracks under 1/8-inch are typically cosmetic, but wider cracks or those that allow water intrusion require attention. For a thorough understanding of what constitutes a serious issue, we recommend reading When To Worry About Cracks In Your Foundation Walls. At Bedrock Foundation Builders, we advise monitoring cracks for changes in width or length. If a vertical crack is accompanied by sticking doors or uneven floors, it may indicate deeper structural movement. Always consult a professional for an assessment to determine if repair, such as epoxy injection, is necessary.

When evaluating cracks in walls, it is important to distinguish between cosmetic and structural issues. Hairline cracks in plaster or drywall are often caused by normal settling or temperature changes. However, horizontal cracks, stair-step cracks in brickwork, or cracks wider than a quarter-inch can indicate serious foundation movement. For homeowners in the Denver area, older homes are particularly susceptible. Our internal article titled Are Cracks In A 100-Year-Old Denver Home Normal? provides specific guidance on this topic. If you notice cracks that are accompanied by sticking doors or uneven floors, a professional inspection is recommended. Bedrock Foundation Builders advises that early identification of crack patterns is key to preventing costly repairs.
