Frequently Asked Questions

Common questions about Certified Best Pick® waterproofing companies in Washington, DC, MD

Best Pick Certified Waterproofing companies in Washington Dc have earned their status through independent consumer research—not paid placement. To qualify, a company must meet strict standards:

  • High customer satisfaction: 4.0+ Google rating (25+ reviews) OR 80%+ recommendation rate from surveyed customers
  • Verified credentials: Active state licenses, general liability insurance, and workers' comp (where required)
  • Financial stability: Clean credit history and active Secretary of State standing
  • Local track record: Minimum 1 year serving the Washington Dc area

Certification is re-verified annually, ensuring continued performance.

No. Waterproofing companies cannot buy Best Pick Certification, improved ratings, or better placement. Our research team independently evaluates companies based on customer satisfaction, licensing, insurance, and business stability—before any business relationship exists.

Companies that earn certification pay a participation fee after qualifying, which covers the cost of ongoing research and publication. This fee has no influence on whether a company qualifies or how they appear in our directory.

The Best Pick Guarantee provides financial protection—up to $2,500 in labor costs—if a Certified Best Pick Waterproofing company fails to deliver on their commitments.

To be eligible:

  • Contact the company through Best Pick Reports or BestPickReports.com
  • Register for the guarantee (free)
  • Submit any claim within 45 days of the final date of service
  • Allow the company the opportunity to resolve the issue first

This guarantee applies only to Certified Best Pick companies, not Standard Pros. Full terms are available on our guarantee page.

Signs include obvious dampness or water in the basement, musty odors, cracks in the foundation, and white powdery residue called 'efflorescence' on walls. In finished basements, look for peeling or puckering paint/wallpaper, water stains, and swollen baseboards.
Services include exterior excavation for advanced problems, interior drainage systems, sealant waterproofing, foundation repair, system inspections, and determining appropriate waterproofing solutions based on individual home needs.
