How Were the Companies Evaluated?
The criteria were Milwaukee-area service, relevant waterproofing or foundation work, published warranty availability, duration, transferability, maintenance requirements, and service-specific limits.
The sponsor receives first placement. The remaining companies are grouped by published warranty type, not reviews, prices, or an assumption that longer is automatically better. Clear coverage matters more than marketing language alone.

Use this checklist before accepting an estimate:
- Exact work, products, walls, or drainage sections covered
- Start date and stated duration of coverage
- Whether labor, materials, parts, or all three are included
- Water-entry conditions or structural movement that trigger service
- Exclusions for plumbing, grading, gutters, power loss, pumps, or extreme events
- Required inspections, maintenance visits, renewal payments, or service fees
- Transferability rules, deadlines, forms, and fees after a home sale
- Responsibility for finished walls, flooring, landscaping, or other restoration

Frequently Asked Questions
Does McCoy Contractors Offer a Lifetime Warranty?
A universal lifetime warranty was not verified. The company confirms transferable warranties, with the specific coverage and terms included in each project proposal.
Is a Transferable Warranty Automatically Passed to the Buyer?
Not always. Some warranties require notice, forms, inspections, fees, or transfer within a deadline. Follow the written procedure instead of assuming coverage changes hands automatically.
Is the Longest Warranty Always the Best Warranty?
No. Coverage definitions, exclusions, maintenance duties, labor provisions, claim procedures, and the responsible company matter as much as the advertised duration.
Can Maintenance Affect Waterproofing Coverage?
Yes. Pump testing, drain cleaning, battery replacement, inspections, membership plans, or documentation may be required for certain systems. Confirm every obligation in writing.
Should the Warranty Be Included With the Estimate?
Request it before signing. The estimate should identify the applicable warranty, and the full document should explain the duration, covered work, exclusions, transfer rules, and claim process.
