Expert Downspout Extension Installation in Lawrence, KS

Downspout extension installation in Lawrence typically runs $35 to $110 for a flip-up or roll-out extension and $250 to $650 for a buried drain line, and it is one of the cheapest ways to protect a foundation. A house sheds a great deal of water. A single inch of rain on a 1,500 square foot roof produces close to a thousand gallons, and a downspout that empties at the base of the wall sends every gallon of it to the foundation.

The goal is distance and direction. A discharge should land at least four to six feet from the house, and farther where the ground is flat or slopes back toward the wall. For open yards, a flip-up extension that lifts out of the mower's way, or a roll-out that unspools during rain and retracts afterward, does the job for very little money. Where a surface run would be tripped over or mowed, a buried drain line is neater. It is trenched with continuous downhill fall, glued at every joint and ends in a pop-up emitter or a daylight outlet, never a dead end.

Flat ground is the hard case, and it is common in North Lawrence, the low floodplain ground north of the Kansas River. With almost no slope, water discharged near a foundation has nowhere to go and sits. A short roll-out there only relocates the puddle a few feet. A buried line carried farther to a pop-up emitter, sometimes paired with a dry well or a shallow swale that gives the water a place to soak in, performs much better.

We handle flip-up and roll-out extensions, buried drain lines, pop-up emitters, splash blocks and downspout re-positioning. Call 877-519-9702 for a free downspout extension estimate.

Our Process

How We Handle Downspout Extension Installation

Read the Grade at Each Downspout

Which way the ground slopes at each outlet decides where the water can go, and how far it needs to travel before it stops being a foundation problem.

Choose Surface or Buried

Flip-up and roll-out extensions suit open ground. A buried drain line suits yards where a surface run would be mowed, tripped over or in the way.

Build the Line With Continuous Fall

Buried lines are trenched with steady downhill pitch, joints are glued, and the discharge is a pop-up emitter or daylight outlet, never a dead end.

Test With Running Water

Each extension is tested with a hose at full flow, confirming the water reaches the outlet and nothing pools near the wall.

How much do downspout extensions cost in Lawrence?

Flip-up and roll-out extensions run $35 to $110 each installed. A buried drain line to a pop-up emitter typically runs $250 to $650 per downspout depending on length and how much digging the yard requires.

How far should a downspout extension carry water from the house?

At least four to six feet, and ideally eight to ten where the ground is flat or slopes toward the house. The goal is for the water to leave the zone around the foundation, not just to reach the end of the pipe.

Are buried downspout drains better than surface extensions?

They are neater and out of the way of the mower and foot traffic, but they cost more and can clog or freeze if built poorly. A surface extension is inexpensive and easy to clean. The right choice depends on the yard.

What is a pop-up emitter?

A small cap on the end of a buried drain line that pops open under water pressure and discharges, then closes when flow stops so debris and animals stay out. It lets a buried line end in the middle of a lawn where there is no downhill to daylight.

Do flat lots in North Lawrence need longer downspout extensions?

Often. The river-floodplain ground north of the Kansas River is very flat, so water discharged near a foundation has almost no slope to carry it away and tends to sit. There, a buried line ending in a pop-up emitter, sometimes with a dry well or a swale, works better than a short roll-out that merely relocates the puddle a few feet.
