Editorial policy

Our goal is to help Greater St. Louis homeowners ask better questions before selecting a drainage solution or service provider.

Who operates this site

STL Drainage Guide is operated by Nfinier, LLC. We publish general educational information and may connect consenting visitors with independent service providers. We do not perform drainage, construction, engineering, waterproofing, or contractor services through this website.

How content is created

Guides are organized around homeowner questions, observable symptoms, common project categories, and publicly available local resources. We distinguish general planning information from a property-specific diagnosis. Local agency links are included where they help readers verify jurisdiction, permits, stormwater programs, or emergency contacts.

Cost estimates

Calculator results and cost articles provide broad planning ranges, not quotes or guarantees. Actual prices depend on site conditions, design, materials, access, utilities, restoration, contractor availability, and approvals. We encourage readers to compare the diagnosis and written scope behind each estimate.

Review and updates

Material guides display a reviewed date. We revisit pages when local programs, source links, service coverage, or major content assumptions change. Readers can report a correction to info@stldrainageguide.com.

Provider relationships

A provider may pay Nfinier, LLC for introductions or other marketing services. Payment does not turn the provider into our employee or agent and does not change the homeowner's obligation to evaluate licensing, insurance, experience, proposal terms, and suitability. Sponsored placements, if introduced, will be identified.

No professional advice

Content is not engineering, surveying, legal, insurance, environmental, or construction advice. Contact the appropriate professional or public agency when the situation requires it.
