Frequently Asked Questions

How do I know if I need foundation repair in Chicago?

Common signs include cracks in basement walls or floors, doors and windows that stick, uneven or sloping floors, gaps around exterior doors or windows, and water seepage. If you notice any of these, it's wise to get a professional inspection.

How long does foundation repair take?

It depends on the method and extent of work. Simple crack injection can take a day, while installing piers might take several days. A typical repair project can last from one day to a week. Your contractor will give you a timeline after the assessment.

Will my homeowner's insurance cover foundation repair?

Typically, insurance does not cover foundation damage caused by settling, soil expansion, or normal wear and tear. However, if the damage results from a covered peril like a burst pipe or a sudden sinkhole, you might be covered. Review your policy or talk to your agent.

What is the difference between epoxy injection and polyurethane foam for crack repairs?

Epoxy is strong and structural, often used for cracks that need to be sealed and bonded. Polyurethane foam is flexible and waterproof, making it ideal for cracks that may move slightly or need moisture protection. Your contractor should recommend the best option based on the crack's cause and location.
