Frequently Asked Questions
Real questions from Northern California homeowners
Is interior or exterior waterproofing better?
Both have applications. Interior systems manage water that enters, while exterior systems prevent water from reaching walls. We often recommend a combination for complete protection.
How long does basement waterproofing last?
Quality waterproofing systems last 25+ years. Sump pumps typically need replacement every 10-15 years. We provide warranties and maintenance guidance.
Will waterproofing fix foundation cracks?
We repair foundation cracks as part of waterproofing. However, structural cracks may require additional foundation repair before waterproofing.
