What to expect after completion
It’s normal for new structures to settle during the first year, and sometimes small settlement cracks can appear. We recommend allowing at least 12 months for your extension to go through all seasons and weather changes. After this time, you can contact our customer support team, and we’ll arrange for any necessary repairs.
Extra protection
For homeowners who want even greater reassurance, we can provide details of additional insurance options. This gives you extended cover throughout the process and beyond, offering complete peace of mind.
