When you move into a new build, your home is essentially “wet.”
Thousands of litres of water were used during the construction of the plaster, concrete, and mortar. As this water evaporates, the house undergoes a process known as “drying out.”
Understanding this phase is vital for property maintenance.
Why Cracks Appear (Shrinkage)
As the materials dry, they shrink slightly. This often results in small hair-line cracks in the plaster, particularly around door frames and ceilings.
In most cases, these are perfectly normal and are not structural defects. However, if a crack is wider than a 2-pound coin, it may require a professional inspection.
Managing Condensation and Damp
Because of the high moisture content, new builds are prone to condensation. To prevent mold growth during the first year:
-
Keep trickle vents on windows open at all times.
-
Use extractor fans when cooking or showering.
-
Avoid drying clothes on radiators.
The Importance of Ventilation
Modern homes are built to be airtight for energy efficiency. While this is great for your bills, it means the house relies heavily on its ventilation systems. Ensure you understand how your MVHR (Mechanical Ventilation with Heat Recovery) system works if your home has one.
When to Worry
While small cracks are normal, large gaps or “stepped” cracking in external brickwork are red flags. These should be noted in your pre-warranty survey to ensure they are addressed before the builder’s liability expires.
Patience is key during the first year of a new home. By allowing your home to dry out naturally and maintaining good airflow, you’ll protect the finish and longevity of your property.
