Mistake 1: Focusing on Price Over Quality

Although cost is an important consideration, prioritizing price over quality may lead to long-term problems. Waterproofing is an investment in your property’s safety and structural integrity, especially in regions with heavy downpours and snowstorms. Opting for a cheap solution may result in recurring issues and increased expenses in the future. To avoid this mistake, research the market, compare quotes, and consider the quality of materials and services offered by different contractors.

Mistake 2: Ignoring Credentials and Certifications

Verifying a contractor’s credentials, licenses, and certifications is crucial for ensuring their expertise and adherence to industry standards. A company should have the necessary training, insurance, and WSIB (Workplace Safety and Insurance Board) coverage to manage potential workplace accidents. Checking for awards or recognition in the industry can also help determine a contractor’s credibility. Always verify a contractor’s credentials before hiring them.

Mistake 3: Neglecting to Check References

Genuine references are invaluable when assessing a contractor’s reliability and past performance. However, some companies may use fabricated or paid references to lure unsuspecting customers. To avoid this trap, check independent review platforms like TrustedPros or HomeAdvisor for unbiased feedback from real clients. Additionally, you can ask friends, family, or colleagues for recommendations based on their personal experiences.

Mistake 4: Not Getting Written Agreements

Verbal promises and assurances are not legally binding. It’s essential to have a written contract outlining the scope of work, materials, warranties, pricing, and the timeline for the project. Ensure that all discussed details are included in the agreement and that both parties sign it. This provides a clear reference for any future disputes or misunderstandings.

Mistake 5: Overlooking DIY Waterproofing Solutions

While professional waterproofing services are often the most effective, some homeowners may consider DIY solutions as a cost-saving measure. Be cautious when using DIY waterproofing products, as they may not offer the same level of protection as professional-grade materials. Additionally, an improper application can lead to further complications. If you decide to pursue a DIY solution, research extensively to avoid being misled by false claims or low-quality products.


By avoiding these common mistakes, you can make an informed decision when hiring a waterproofing contractor. Remember to prioritize quality over price, verify credentials, check references, obtain written agreements, and carefully consider DIY solutions. Taking these precautions will help you find the right contractor to protect your property from water damage and ensure a successful project outcome.
