Settlement in a new build home refers to the natural adjustment period during which a newly erected house adapts to its foundational and environmental factors.
Over time, as the underlying soil compresses and stabilises, there may be a slight shifting or sinking of the house. This process, known as settlement, is a standard occurrence in the lifecycle of a new home.
Settlement and Its Consequences
During the initial period following construction, settlement can manifest in minor cosmetic alterations, most commonly hairline cracks appearing in the walls or ceilings. Typically, these cracks are harmless and expected as the home settles into its environment. However, substantial cracks or structural anomalies may indicate a serious issue. In such instances, it’s crucial to consult with a professional builder or structural engineer for an assessment.
Factors that Influence Settlement
Numerous factors contribute to the process of settlement, including the conditions of the soil, the local climate, and the construction techniques utilised. Builders generally consider these factors in their construction plans, incorporating practices to mitigate the impact of settlement.
These include adequate foundation design and soil compaction. It’s also common for new build homes to include warranties covering settlement-related concerns for a specified duration. Therefore, homeowners are encouraged to thoroughly review their warranty documentation for more detailed information.
Dealing with Settlement
If you’re a homeowner grappling with potential settlement issues, your best resource is often the builder or developer responsible for your home’s construction. They can provide specific guidance and address any concerns or queries you might have about the settlement.
Minimising Cracks During Settlement
While minor settlement and cracking are a normal part of a new home’s lifecycle, there are preventative measures that homeowners can take to reduce the extent of cracking. These include:
Proper Construction Techniques
Engaging a reputable builder who adheres to industry best practices can lessen the likelihood of excessive settlement and cracking.
Soil Assessment and Preparation
A comprehensive soil assessment prior to construction provides insights into the specific soil conditions on your property. This knowledge aids in implementing the best soil preparation techniques, such as soil stabilisation or compaction, to create a robust foundation for your home.
Moisture Control
Moisture levels in the soil can significantly contribute to settlement and cracking. Hence, proper drainage systems around your home’s foundation are necessary to prevent water buildup. Regular checks on gutters, downspouts, and landscaping that supports effective water runoff can help in controlling moisture.
Adequate Curing Time
Rushing the construction process can lead to increased cracking. Allowing ample time for building materials, like concrete or masonry, to cure before moving onto finishing work can prevent this.
Temperature and Humidity Control
Fluctuations in temperature and humidity during construction can affect the curing and settling process. Keeping these factors consistent during construction can help mitigate cracking.
Expansion Joints
Using expansion joints in construction allows for the controlled movement of materials, thereby reducing the likelihood of cracks appearing.
Regular Maintenance
Once you move in, promptly address maintenance issues. Early detection and repair of minor cracks can prevent them from worsening over time. Monitor changes in your home’s structure and consult with professionals if needed.
Defining Cracks and Determining Responsibility
Cracks in construction and home contexts are defined as fractures or separations in building materials. These can vary from minor hairline cracks to more significant and concerning fractures.
Responsibility for such cracks in a new build home can depend on several factors, including the cause of the crack, builder warranties, and local building regulations. Construction-related issues typically fall under the builder’s responsibility, while cracks resulting from natural settlement or external factors often rest with the homeowner. In certain cases, external factors like natural disasters or nearby construction may necessitate homeowners to consult their insurance policies or legal advice to determine liability.
Understanding your construction contract and warranty, as well as any local building regulations, is critical. If you notice any significant cracks in your new build home, contact the builder or developer promptly for an assessment. In more serious cases, the expertise of a professional structural engineer may be required.
While settlement and minor cracks in new homes are generally expected, understanding the causes, prevention techniques, and responsibilities can help homeowners maintain the integrity and longevity of their homes.
