What's Wrong With My Concrete?
To identify what may be wrong with your concrete, choose the symptom that most closely matches what you see. The guide explains common causes, warning signs, and reasonable next steps without treating appearance alone as a final diagnosis.
What are you seeing?
Select a symptom to see possible causes, observations to record, and what to ask before choosing a repair.
When Should You Call a Professional?
Call a qualified professional when concrete damage involves movement, uneven surfaces, recurring deterioration, or a possible structural concern. Appearance alone cannot establish the cause. The following conditions warrant assessment:
Once the cause is understood, compare the likely scope in the concrete repair cost guide and use the repair versus replacement checklist before requesting bids.
What is this guidance based on?
The symptom descriptions draw on NRMCA guidance about cracking, scaling, delamination, and discoloration. These are possible explanations to discuss during an assessment, not findings about your property. Reviewed September 26, 2026.
