Buying a home is one of the most exciting (and nerve-wracking) experiences in life. You’ve found the one — perfect location, charming features, and the potential to make it truly yours. But then, the survey comes back and flags something worrying: a crack in the wall. Now what?
First things first: don’t panic. A crack doesn’t automatically mean disaster, but it does mean you need to look a little closer before signing on the dotted line.
Cracks can be caused by a variety of things — from harmless settlement in new builds to more serious issues like subsidence or structural movement. The surveyor’s job is to spot potential issues, but they won’t always have the full picture.
Should I still buy the house?
It depends. The presence of a crack is a sign that you need to gather more information, not necessarily walk away.
Here’s what you could do:
1. Speak to your surveyor
Call your surveyor to discuss over they phone. They may be able to provide further insight or advise on further investigation.
2. Get a second opinion
If the survey flags a crack as potentially significant, it may be prudent to seek further specialist advice. A structural engineer will be able to assess whether the crack is due to structural movement, what caused it, and — crucially — whether it’s stable or worsening.
If you’re planning renovation works (like extending or reconfiguring the layout), consider also speaking to an architect. They’ll help you understand not just the seriousness of the crack, but also how it might impact your renovation plans. Architects often collaborate with engineers, especially when structural changes are involved in a renovation. It’s better to know early if a crack will complicate (or limit) your ideas.
3. Understand the cause
Cracks can occur for many reasons — thermal expansion, drying shrinkage, natural settlement, poor construction, or ground movement. A small, stable crack might be nothing to worry about, but an active crack could suggest ongoing movement.
4. Consider the cost and impact
Even if the crack turns out to be harmless or repairable, it’s worth considering:
Will it affect your renovation plans?
Will it affect resale value or future surveys?
Will lenders be comfortable offering a mortgage?
If you’re already imagining a loft conversion, kitchen extension, or open-plan living space, understanding the structural context is essential. Your architect can help determine whether your vision is still viable — or if compromises need to be made.

4. Make an informed decision
Buying a home is a big emotional and financial commitment. A visible crack might feel like a red flag, but in many cases, it’s more of a yellow light: pause, investigate, then proceed if it makes sense.
Having professional input not only gives you peace of mind but can also arm you with negotiating power. If the crack will require remedial work, you may be able to renegotiate the price with the seller.
Final thoughts
A crack in a property isn’t always a deal-breaker, but it is a sign to slow down and seek professional advice. Whether you’re buying your forever home or planning a transformative renovation, bringing in an architect or structural engineer at this stage can make all the difference.
