Choosing the right waterproofing contractor is crucial for protecting your home from water damage, leaks, and foundation issues. But do not fear, for Aquatech Waterproofing is here! Not all contractors offer the same level of expertise, quality, or service. Before hiring a waterproofing professional, ask these 10 essential questions to ensure you’re making the best decision for your home.
1. Are You Licensed and Insured?
A reputable waterproofing contractor should be fully licensed and insured. Licensing ensures they meet industry standards, while insurance protects you in case of property damage or worker injuries during the project.
2. How Long Have You Been in Business?
Experience matters when it comes to waterproofing. Contractors with several years of experience are more likely to understand complex foundation issues, drainage systems, and long-term solutions.
3. What Waterproofing Methods Do You Use?
There are different waterproofing techniques, including:
- Exterior waterproofing (membranes, weeping tiles, drainage systems)
- Interior waterproofing (sealants, sump pumps, vapor barriers)
- Foundation crack repairs
- Basement encapsulation
A knowledgeable contractor should explain the best method for your specific situation.
4. Do You Offer a Free Inspection and Estimate?
A professional waterproofing contractor should provide a detailed inspection and written estimate. This helps homeowners understand the scope of the project and compare costs before making a commitment.
5. What Is Included in the Warranty?
Reliable waterproofing companies offer warranties for their work. Ask about:
- Length of coverage
- What is covered (materials, labor, drainage systems)
- Whether the warranty is transferable if you sell your home
6. Can You Provide References or Customer Reviews?
Ask for references from previous clients or check online reviews to see their track record. A reputable company should have positive testimonials and be willing to share customer experiences.
7. How Long Will the Project Take?
Timelines vary based on the complexity of the project. A contractor should give you a realistic timeframe for completion and explain potential delays (weather, permits, unforeseen issues).

8. Do You Handle Permits and Compliance?
Some waterproofing projects require permits or compliance with local building codes. Ensure your contractor is familiar with Hamilton’s waterproofing regulations and handles necessary paperwork.
9. What Are the Total Costs and Payment Terms?
Ask for a detailed breakdown of costs, including:
- Materials
- Labor
- Additional fees (permits, excavation, drainage systems)
Clarify payment terms, deposits, and financing options before signing a contract.
10. What Maintenance Is Required After Waterproofing?
Even the best waterproofing systems require maintenance. Ask about ongoing care, sump pump maintenance, and drainage system upkeep to keep your basement dry in the long run.
