One storm away from a $20,000 problem.
Columbus's only sump-pump-exclusive company. No plumbing side gigs, no water heaters, no weekend HVAC calls. Just pits, pumps, and the drainage around them.
Most weeks we can see you within 5 business days.
Why specialize when everyone else doesn't?
Because the alternative is a generalist plumber who opens a pit maybe four times a year, and has never watched what Columbus clay does to a float switch over eight winters.
We only do sump pumps
That focus shows up in installs that outlast a generalist's work by years. A specialist has opened a thousand pits; a generalist has opened forty.
We'll tell you if you don't need us
If your pump has five years of life left, we'll say so and leave. We don't manufacture urgency. Our whole business works because homeowners recommend us, not because we oversell.
No surprise quotes
You know the full price before we start. The number we quote is the number you pay. No "once we opened it up" add-ons, no upsell at the truck.
Built for Columbus soil
Clay that won't drain, a water table that won't quit, and houses built before the '40s with foundations to match. That's what we see all week, and it's what our installs are designed for.
Photos from last week.
No staging, no stock. Just the pits we actually opened and the pumps we actually pulled out. Some of these houses you probably drive by.
Ryan — founder of K-Sump.
You get me on the assessment, on the install, and on the warranty call. Not a dispatcher, not a different tech each time. One guy who's been inside hundreds of Columbus basements and knows what your soil and your storms actually do to a pump.
The person who quotes the work is the person who does the work. That keeps me honest, and it keeps the quote realistic.

“Ryan took the time to explain exactly what was going on with our old sump pump and what we actually needed — no upsell, no pressure. The new system has been running perfectly through two major storms.”

“After getting wildly different quotes from three plumbers, K-Sump was the only one who showed me why my system was failing instead of just quoting a replacement. That honesty earned my business.”

“The K-Guard maintenance plan is the best money I've spent on this house. They caught a failing check valve before it would've flooded my finished basement. Can't recommend them enough.”

“Our yard used to pool water against the foundation after every heavy rain. K-Sump re-graded and added a French drain — two storms later, completely dry. They actually fixed the root cause.”

What we do.
Three services, and the thread that connects them is water management. Anything outside that, we refer out.
K-Guard Maintenance
Catch the $200 fix before it becomes a $20,000 flood. A stuck float caught in July is a cheap repair; the same float failing during a September storm isn't.
Pump testing, basin cleaning, battery checks, discharge line inspections.

Stop water before it reaches your walls. A great sump pump cannot save you if your gutters and grading are aiming every storm at your foundation.
Drainage work designed for Central Ohio's heavy clay, where water has nowhere to go but in.

Book the assessment
Pick a slot that works. Ryan comes out, looks at the whole system, asks a few questions about what you've noticed. Usually 30 to 45 minutes in the basement.
Get an honest recommendation
We show you what we found, explain your options, and give you a fixed price. Quotes don't expire. Take a week to think about it; the number stays the same.
Install day
If you move forward, most installs wrap up in a day. We clean up after ourselves, haul the old pump away, and walk you through the new system before we leave.
Questions we hear on the driveway.
The ones homeowners actually ask, answered plainly.
Every basement is different, so we give you a fixed, honest quote after a free in-home assessment — not a ballpark guess over the phone. No hidden fees, no surprise add-ons. The number we quote is the number you pay.
Most installations are completed in a single day. We show up in the morning, and by the afternoon your system is running and tested. Complex jobs involving drainage work may take two days — we'll tell you upfront.
We install Pro Series combo systems — primary pump plus battery backup. We chose this line because it's built for high-cycle environments like Columbus, where pumps run hard during spring storms. We don't carry five brands to upsell you. We carry the one we'd put in our own basement.
Yes. Every install comes with a 1-year free labor warranty and a 3-year manufacturer equipment warranty. Upgrade to 3 years of labor coverage with our K-Guard annual maintenance plan or as a one-time add-on. If something isn't right, we come back and fix it. Period.
We'll tell you. If your current system has years of life left, we're not going to push a replacement. We'd rather earn your trust now and your business later. Our free assessment gives you an honest picture of where your system stands.
We serve Columbus and the surrounding suburbs — Clintonville, Westerville, Dublin, Hilliard, Grove City, Upper Arlington, Worthington, Gahanna, Reynoldsburg, and many more. If you're in the Central Ohio area, we can almost certainly help.
