Moving into a newly built home is an exciting experience, but it can also come with its fair share of challenges.
One of these challenges is understanding what’s the difference between settlement and shrinkage snagging.
As a homeowner, it’s important to know how these issues can affect the structural integrity of your new home and how to address them.
In this blog post, we’ll explore the causes, signs, and prevention strategies for settlement and shrinkage issues in new homes, as well as the role of snagging surveys in detecting and managing these problems.
So buckle up and get ready for an informative journey into the world of new home construction!
Settlement and shrinkage are common occurrences in newly constructed homes, often resulting from the high water content of building materials during the drying-out process.
Although both issues occur and can cause cracks and other structural defects, they have distinct causes and manifestations.
Understanding the differences in property front between settlement and shrinkage is crucial for homeowners, as it helps in identifying the root causes of these problems and taking appropriate remedial actions.
Settlement is primarily caused by the weight of the house on its foundations. Various factors can contribute to the settlement, including weak-bearing soils, improperly backfilled soils, inadequate compaction, and the weight of the structure itself.
Soil type and moisture content are among the natural factors that can also influence settlement.
The extent of the settlement will vary depending on the type of foundation and construction method employed, such as timber framing versus traditional building.
Settlement cracks may be observed particularly around door frames internal walls, windows, and staircases.
Shrinkage, on the other hand, is the result of the drying out of building materials, such as mortar, plaster, and concrete.
The most frequent outcome of shrinkage is the emergence of cracks between woodwork and walls.
Nail pops, which manifest as raised, round bumps on walls and ceilings, are another common paint show phenomenon resulting from shrinkage and settlement of paint.
Although shrinkage wall cracks are generally narrow in width and may run along the wall or the top of walls, they can still be unsightly and cause concern for homeowners.
A snagging survey is a comprehensive assessment of a newly constructed residence that aims to detect any imperfections or matters that require attention.
These surveys play a crucial role in identifying settlement and shrinkage cracks, helping homeowners address potential issues before they escalate into more significant structural problems.
By thoroughly examining various indicators of settlement and shrinkage, snagging surveys provide invaluable information to homeowners and builders alike.
During a snagging survey, signs of settlement cracks can be detected by observing small, hairline cracks in walls, ceilings, and plaster.
Cracks in brickwork, floor tiles, and around windowsills and window frames are also indicative of settlement issues.
However, if the cracks are larger than 1/16 inch, horizontal or diagonal, or wider at the top than the bottom, it could be indicative of a more serious issue with the structural integrity of the building.
By identifying these issues early on, homeowners can take the necessary steps to address settlement problems and prevent further damage to their property.
A snagging survey can also detect signs of shrinkage, including cracks in plaster and woodwork.
Shrinkage cracks are primarily caused by ground movement, clay shrinkage, and the sometimes drying out process of construction materials such as mortar, plaster, and concrete. These cracks are generally narrow in width and may run along the ground or top of walls.
Although shrinkage cracks do not indicate any structural issues or inferior construction, they can still be a cause for concern and should be addressed promptly to maintain the aesthetic appeal of the home and ensure its long-term structural integrity.
As we’ve seen, snagging surveys play a crucial role in detecting and preventing settlement and shrinkage issues in new homes.
By identifying potential problems early on, homeowners can take the necessary steps to address these issues and ensure the long-term structural integrity of their property.
In addition, snagging surveys provide invaluable information to builders, helping them improve their construction practices and deliver high-quality homes that meet the expectations of their clients.
A snagging survey is a comprehensive assessment of a newly constructed dwelling, conducted by a qualified surveyor, to detect any flaws or issues that require resolution.
The primary purpose of a snagging list is to assist the builder in recognising and rectifying any defects or deficiencies in the construction.
In the event of detecting any defects during the demonstration of your new home, it is recommended to make a note of these, as this will assist the builder in understanding what needs to be done to address them.
Snagging surveys detect settlement and shrinkage issues by using crack gauges and date-stamped photographs to observe any changes in cracks over time.
This enables the surveyor to identify potential problems and provide homeowners with the necessary information to address these issues before they escalate into more significant structural concerns.
By detecting signs of settlement and shrinkage, such as cracking in brickwork, floor tiles, and around windowsills and door frames, snagging surveys help homeowners and builders alike ensure the long-term structural integrity of newly constructed homes.
Although snagging surveys are crucial in detecting settlement and shrinkage issues, homeowners also play a vital role in preventing and managing these problems.
By implementing appropriate strategies and following recommended guidelines, homeowners can minimise the risk of settlement and shrinkage in their new homes.
In this section, we’ll discuss various strategies for preventing and managing settlement and shrinkage issues, as well as the role of ventilation and central heating in reducing the likelihood of these problems.
Proper ventilation and heating are essential in preventing and managing settlement and shrinkage issues in new homes.
Adequate ventilation can be achieved by opening doors, windows, and vents to allow for more natural airflow, utilising fans to circulate air, and employing a thermostat to maintain a consistent temperature.
In addition, maintaining a consistent temperature throughout the home helps reduce the risk of moisture buildup and other issues that can lead to settlement and shrinkage.
By carefully managing ventilation and heating during the initial 12-18 months in a new home, homeowners can minimise the risk of settlement and shrinkage issues and ensure the long-term structural integrity of their property.
Addressing settlement cracks, and shrinkage cracks in a timely manner is crucial in preventing further damage to the property. Settlement cracks should be addressed if you notice that they are greater than 1/16 inch in width.
If shrinkage cracks exceed 2mm, it is recommended to contact the New Home Customer Care team, as these repairs are required to be done under warranty.
By promptly repairing cracks and addressing any underlying issues, homeowners can ensure the long-term structural integrity of their new homes and protect their investments.
Understanding the warranty coverage for settlement and shrinkage issues is essential for homeowners, as it helps determine the responsibilities of builders and insurance providers in addressing these problems.
In this section, we’ll discuss the warranty coverage provided for settlement and shrinkage issues, as well as the responsibilities of builders and insurance providers in rectifying these concerns.
Builders are responsible for addressing large shrinkage cracks, but not normal settlement cracks.
Additionally, any defects resulting from poor workmanship or defective materials during the defects liability period, which is typically 12 months from the completion of construction, must be rectified by the builder.
By understanding their responsibilities to build the home itself, builders can ensure that they address settlement and shrinkage issues and build homes, promptly and effectively, providing homeowners with the peace of mind that their new homes are structurally sound and built to last.
The structural insurance period typically lasts for up to 10 years following the completion of the home.
This coverage provides homeowners with protection against settlement, cracking and shrinkage issues, as well as other structural defects that may arise during this period.
Structural insurance coverage includes foundations, walls and cladding, roofs, flues and chimneys, ceilings, load-bearing parts of the floor, and glazing in external windows and doors.
By understanding the coverage provided by structural insurance, homeowners can ensure that they are adequately covered and protected against potential settlement and shrinkage issues in their new homes.
In conclusion, understanding the differences between settlement and shrinkage snagging is crucial for homeowners who want to ensure the long-term structural integrity of their new homes.
By learning about the causes, signs, and prevention strategies for these issues, homeowners can take the necessary steps to address them promptly and effectively.
The role of snagging surveys in detecting and managing settlement and shrinkage issues cannot be overstated, providing homeowners and builders alike with invaluable information to maintain the quality and longevity of newly constructed homes.
With this knowledge at your fingertips, you can confidently navigate the challenges of new home construction and enjoy the peace of mind that comes from knowing your investment is protected.
Shrinkage cracks are caused by concrete shrinking as it dries, while settlement cracks occur when the soil underneath the slab settles.
Shrinkage cracks appear in a web-like pattern, while settlement cracks tend to be much wider and have vertical displacement across them.
Overall, shrinkage cracks are far more common than settlement cracks.
Shrinkage can definitely be a snag in newly built homes; any movement in the construction of newly built homes that causes noticeable cracks may mean that the foundations and framework of the property have not been properly prepared or laid.
This can be a major issue, as it can lead to further structural damage and even the need for costly repairs.
It is important to ensure that the foundations and framework of a property are properly laid and prepared to avoid any issues with shrinkage.
Settlement cracks can be concerning, however, in most cases they are normal and nothing to worry about.
In general, minor cracking is caused by a process of settlement, shrinkage or thermal movement, and it is uncommon for it to cause structural damage.
If you are concerned, the National House Building Council (NHBC) suggests consulting a surveyor.
