Signs your drainage needs work

• Water or damp patches where the floor meets the wall
• A musty smell, or white chalky deposits on concrete
• Puddles that sit against the foundation after rain
• Downspouts that run onto the ground instead of into a drain

Start with the cheap fixes: clean gutters, and make sure downspouts and the ground slope carry water away from the house. Then get the perimeter drain camera-inspected before agreeing to a full replacement.
