Responsibility for settlement cracks in walls generally falls on the homebuilder if the house is new and under warranty, or the homeowner for routine maintenance of minor, cosmetic cracks. If cracks stem from significant structural issues, such as poor soil compaction or foundation defects, the builder may be held liable.
Most settlement cracks are entirely cosmetic and won't affect your home's stability or safety. They typically appear during the first year as your home settles and materials dry out. The most common settlement cracks are hairline cracks measuring less than 2mm in width - about the thickness of a pound coin.
Does my home insurance cover cracks in walls and rendering? Most home insurance policies don't cover cracks caused by general wear and tear or poor construction. Homes need regular maintenance, or looking after, and that's not something that insurance companies cover. So, regular maintenance is essential.
Professional evaluation by a structural engineer is recommended for significant or expanding wall cracks to assess and address potential structural damage.
Generally, foundation cracks or settling aren't covered by your homeowners policy. Your home's foundation is protected under your policy's dwelling coverage, but only for certain perils/events.
Normal settling cracks in houses are typically thin, shallow, and stable over time. They often appear in drywall or plaster as a home adjusts to minor shifts in the foundation. On the other hand, problematic foundation cracks tend to be wider, grow over time, or follow specific patterns that indicate structural stress.
The most common drywall cracks are thin, spiderweb-like hairline cracks that measure less than one millimeter wide. They're caused by normal house settling or minor fluctuations in temperature and humidity. They do not require immediate attention.
Decreased Property Value
Drywall cracks can significantly diminish the market value of a property. Prospective buyers often view such defects as indicators of potential structural issues, leading to lower offers or a complete lack of interest.
The correct repair solution for house settling cracks depends on whether the crack is structural. Non-structural cracks can usually be fixed using epoxy or polyurethane foam injection. However, structural cracks caused by differential settlement may indicate the house needs underpinning.
A hairline crack caught early might cost $200–$800 to repair, while waiting until it has widened and caused structural issues could push repairs into the $10,000–$15,000 range or higher. The depth of repair needed also significantly impacts cost.
Large cracks wider than 5 millimeters are a cause for concern, especially if they are diagonal, horizontal or above a door frame. These cracks could indicate foundation movement, stress on structural supports or settling issues.
Foundation cracks wider than 1/4 inch typically require professional repair, while hairline cracks under 1/8 inch wide are often cosmetic and result from normal concrete settling.
If the cracks you're trying to repair are quite large and deep, or wider than five millimetres, you may need to contact a structural engineer who can determine the cause and how it can be fixed. However, small hairline cracks in a plastered wall can be repaired relatively easily. Speak to a professional for advice.
The "3-3-3 rule" in real estate isn't a single guideline but refers to different strategies: for buyers, it's about financial readiness (3 months savings, 3 months reserves, 3 property comparisons) or a financial affordability check (30% income, 30% down, 3x income); for agents, it's a marketing habit (call 3, note 3, share 3) or prospecting (talking to everyone within 3 feet). There's also a developer rule (1/3 land, 1/3 build, 1/3 profit), though it's considered outdated by some.
There is an inexpensive and highly effective way of repairing cracked walls called crack stitching. With a crack stitching kit, you can repair vertical and stepped cracks to protect the structure of your home. You will need to follow instructions closely when repairing cracks in walls.
Home insurance might cover foundation repair, but only if the damage stems from a sudden, accidental event listed in your policy (like a burst pipe, fire, or storm), not gradual issues like wear-and-tear, soil settling, or neglect, which are typically excluded. Common covered causes include vehicle impact, vandalism, explosions, and certain natural disasters (excluding floods/earthquakes, which need separate policies).
You can tell if a crack is structural by checking its width (over 1/8 inch), pattern (horizontal, stair-step, or diagonal), location (corners of windows/doors), and if one side sticks out more than the other, which indicates significant foundation movement or pressure, unlike hairline cracks that are usually cosmetic. Structural cracks are deeper, may be accompanied by bowing walls or sagging ceilings, and signal a serious issue needing professional inspection.
Foundation repair costs can vary widely, starting from around $300 for minor crack repairs up to $30,000 or more for comprehensive solutions addressing substantial foundation settlement. The precise cost depends on numerous factors and requires a professional assessment.
