The longer answer
Why it happens so much in KC: plenty of metro homes — especially split-levels and homes with basement garages — were built with the driveway falling toward the house because that's where the street is. Add a hard summer storm dropping 2–3 inches an hour and the driveway becomes a river with your garage at the delta. Freeze that same water in January and the door seals to the slab.
What actually fixes it:
- A channel drain across the apron — the purpose-built answer. We saw-cut the concrete just uphill of the door, set a grated NDS channel sloped so water moves inside it, tie it into a buried discharge line to daylight or a pop-up emitter, and re-pour the concrete cleanly around it. Most driveways $1,500–$3,500 installed.
- Check the roof water first — sometimes half the "driveway river" is a downspout emptying onto the slab uphill. If so, burying that downspout ($300–$700) shrinks the problem before the channel handles the rest — occasionally it IS the fix, and we'll say so.
- What doesn't work: rubber threshold ramps (water goes around and under), caulking the door seal (the water finds the slab joints), and re-sloping an entire driveway (usually costs multiples of a channel drain).
Winter question we always get: the channel and its buried line are run at continuous downhill slope so water drains through between storms instead of sitting — nothing standing, nothing to freeze solid. Grates are removable for cleaning, and the sediment rides to a basin or outlet you can actually reach.
