Frequently asked questions
How should I choose a basement waterproofing company?
Look for companies with consistent, recent customer reviews, clear written estimates, and proof of insurance and licensing where required. Ask for references or photos of past work and compare at least two or three proposals to judge scope and materials.
What does basement waterproofing typically involve and how long does it take?
Waterproofing can include sealing cracks, installing interior drains or sump pumps, improving exterior grading, or applying coatings; the right approach depends on the source of water. Timelines vary with scope—minor repairs can be completed in hours, while installing a drainage system or making structural fixes may take several days.
What should I check before hiring a waterproofing contractor?
Confirm the company carries liability insurance, get a detailed written estimate and timeline, and ask about warranties or maintenance plans. Also verify that the proposed work addresses the root cause of moisture rather than just cosmetic fixes.
