Des Moines Egress Windows Window Well Cost Calculator
Window well work covers four very different jobs at four very different prices, and most people searching for a number do not know which one they need yet. This calculator prices all four from the same pricing page ranges: full replacement, relining, drainage, and covers.
The one input that surprises people is the flooding question. A well that holds standing water is not a well problem, it is a drainage problem wearing a well as a hat, and rebuilding the gravel column under the well is what determines whether the new one lasts twenty-five years or five. It is also the one thing nobody can quote from a photograph, which is why the on-site measure exists and why it is free.
Reading your own well before you call
- Screwdriver at the soil line. Solid steel under the scale means a liner is on the table. Perforated steel means replacement. The rusted well page has the full test.
- Tape across the face and out from the wall. Code wants at least 9 square feet of horizontal area and at least 36 inches of projection on an egress well.
- Depth from grade to the bottom. Past 44 inches, a permanent ladder is required.
- Watch it in a spring thaw. Standing water for days is the drainage answer, and the flooding page explains why that happens here specifically.
Send the estimate to the form when you are done and the measure gets booked with the scope already understood. If the window inside the well is also undersized for a bedroom, the egress cost calculator prices that larger job instead.
What will my window well work cost?
Four questions covering wells, liners, covers, and drainage. The ranges are the ones published on our pricing page.
Wells run $1,000 to $3,000, liners $400 to $900, drainage $300 to $1,000, and covers $150 to $600 on the pricing page. This calculator combines those, which is what most real jobs are.

Frequently Asked Questions
Why does 'it floods' change the price so much?
Because the fix is underground. A well that holds water has a silted or missing gravel column, and rebuilding that means excavating below the well, laying clean washed rock with fabric, and finding an outlet, either the footing drain or a deep dry well. That is the work that makes the new well last.
Is a liner a real fix or a patch?
A real fix when the well still has structure. If the steel passes a screwdriver test at the soil line and the anchors are tight, a liner at $400–$900 buys years for a fraction of a replacement. If the steel is perforated or the well has bowed, a liner hides a load-bearing failure and we will say so.
Do I need a ladder in my well?
If the well is deeper than 44 inches and the room behind the window is used for sleeping, yes. Code requires a permanently attached ladder with rungs at least 12 inches wide, projecting at least 3 inches, spaced no more than 18 inches apart.
Can well work be done in winter?
Covers yes, excavation usually not. Frost here reaches roughly 42 inches, which is the same depth the well occupies. Quotes and permits are good winter work; digging waits for April in most years.
