Waterproofing in Chicago: what to know
Chicago winters are long and cold, with sub-freezing stretches and lake-effect snow, followed by warm, humid summers. Two-flats, bungalows and older brick homes are common, many with basements that need attention during spring thaws and heavy rain.
- Snowmelt and spring thaws push water into basements through cracks and wall joints.
- Older stone and block foundations often need interior drainage and a sump pump to stay dry.
- Spring storms and poor grading are the main causes of wet basements and crawl spaces.
How much does waterproofing cost?
- Basement waterproofing: $3,000 – $10,000
- Sump pump installation: $800 – $2,000
- Sump pump repair: $150 – $500
