Homeowners want to know how far a downspout needs to discharge from the foundation, whether a buried drain pipe will clog, and whether a pop-up emitter or dry creek bed is the right outlet. A website that explains foundation clearance earns the drainage call. Free mockup, no commitment.
For Drainage in KC
Web Design for Downspout Extension Companies in Kansas City
Downspout extension customers are homeowners whose downspouts terminate at splash blocks directly against the foundation, whose basement takes on water after heavy rain, or who have erosion channels in the yard directly below the downspout discharge. The central education is foundation clearance and slope: the IRC and most KC-area codes require that roof drainage be directed away from the foundation — the general standard is at least 6 ft of clearance from the building, though 10 ft is preferable in clay soil where water spreads slowly. A splash block that ends 18" from the foundation puts the entire roof drainage load into the backfill zone directly beside the footing — this is a primary cause of basement water intrusion that homeowners attribute to a waterproofing problem rather than a drainage problem. Surface extensions: flexible downspout extensions (roll-out Dex-O-Tex style) are the cheapest solution but create trip hazards and are frequently rolled back into the gutter by mowing. Underground drainage: 4" corrugated or SDR-35 PVC pipe buried at minimum 1% slope (1" drop per 8 ft of run) from the downspout adapter to a pop-up emitter at the discharge point — pop-up emitters (Flo-Well, NDS) open under flow pressure and close to prevent animal entry when dry. Corrugated pipe disadvantage: perforations intended for absorption trench applications are sometimes incorrectly used in solid-pipe drainage runs — perforated corrugated pipe in clay soil accepts water that then saturates the burial trench and the soil immediately adjacent to the house. Solid pipe is correct for discharge applications. Outlet options: pop-up emitter (most common, low maintenance), dry creek bed (decorative, disperses flow), drywell/French drain terminus (for sites with no grade slope to discharge), or tie-in to storm sewer if permitted by municipality. A downspout extension website that explains the foundation clearance requirement, underground pipe options, and outlet types earns the homeowner whose basement floods after every KC thunderstorm and does not know why.
What homeowners research before extending downspouts
- Foundation clearance — how far downspout discharge needs to be from the building, why 6–10 ft matters
- Underground vs. surface extensions — buried drain pipe vs. roll-out extensions, longevity difference
- Perforated vs. solid pipe — why perforated corrugated is wrong for discharge runs in KC clay
- Pop-up emitters — how they work, maintenance requirements, alternatives for flat yards
- Basement water connection — why drainage problems look like waterproofing problems
What your drainage website would include
- Foundation clearance section — IRC standard, KC clay soil behavior, why splash blocks fail
- Underground pipe guide — solid vs. perforated corrugated, SDR-35 PVC, minimum slope requirement
- Outlet options — pop-up emitter, dry creek bed, drywell, storm tie-in — when each is right
- Basement connection section — how undersized or mislocated drainage causes basement flooding
- Site assessment — what we look for when evaluating slope, soil type, and discharge options
- Quote form with number of downspouts, yard slope, basement water history, outlet preference
What clients say
“My best calls came from homeowners who had already spent money on interior waterproofing and still had a wet basement. The website section connecting downspout discharge directly to foundation water intrusion changed who was calling me — customers came in already asking whether drainage was their real problem instead of assuming they needed another sump pump. The pipe type section also helped me explain to customers why I was not using the corrugated perforated pipe they saw at the hardware store — they already understood why before I got to the job.”

Simple pricing
A drainage site with foundation clearance section, pipe guide, and quote form starts at $200. A full site with outlet options, basement connection section, and site assessment guide is $425–$750. One underground downspout run covers the cost. No contracts, no monthly fees.
