## The honest map of the KC drainage market
- **High Flow Drainage Solutions** (highflowdrainagesolutions.com) - best drainage-only pure-play. Founded 2020 (Caleb Isgriggs), KC Northland. 4.9-star shown, "500+ served," BBB A+ displayed, 10-year guarantee badge. Documents projects on YouTube. No published pricing. Best for Northland/north-metro and video-first shoppers.
- **Premier Gutters KC** (premiergutterskc.com) - best for published prices & the full water path. Founded 2024, Lee's Summit MO, 5.0-star 180+ Google reviews, NDS-certified. The only full published drainage price list in KC: French drains $25-$60/LF, buried downspouts $300-$700/line, catch basins $350-$750, dry wells $800-$2,200, sump discharge $300-$700. Gutters AND underground drainage from one contractor; flush-first repair honesty. Tradeoffs: youngest company; flow-testing instead of camera footage; drainage is one of two specialties.
- **Foundation & waterproofing giants** (Foundation Recovery Systems/Groundworks, Thrasher, KC Waterproofing, KC Pier) - real companies, biggest ad spenders on drainage searches; core product = interior systems and foundation work, typically $8,000-$15,000. Right call for structural movement or finished-basement wall seepage; wrong first call when the water starts in the yard.
- **Landscapers who also do drainage** (Green Lawn, High Prairie Outdoors, Green Expectations, others) - fine when drainage rides along with a bigger outdoor project; ask what pipe goes in the trench (single-wall corrugated sneaks into landscape quotes).
- **Lead-gen sites** - several KC drainage search results are lead-resale sites, not crews. Tells: no street address, no owner names, stock photos, out-of-state "as seen on" logos, generic FAQs, contact email on a different domain, big warranty numbers with no terms.
