What pushes the price up
- Depth. A deeper basement means a deeper well and more digging. Once the well is deeper than 44 in., it needs a ladder or steps.
- Size. An egress well needs at least 9 sq ft of floor area and 36 in. of projection from the wall, so it's bigger than many older light wells.
- Material. Stone and concrete sit at the high end.
- New egress or replacement? A new egress window adds the foundation cut and the window. Our Denver egress cost guide breaks those down.
Does a window well need a permit?
Adding a new egress window and well in Denver needs a permit, and Denver bases the fee on project value. See our Denver egress permit guide and Denver's official fee page. Other cities set their own fees, so check with your building department.
Replace the well, or upgrade to egress?
If the window behind the well is too small to climb through, a new well alone won't make that room a legal bedroom. Run the opening through our egress window check first. Then see window well installation or egress window installation.
Nearby. We set up projects across the metro, including Denver, Aurora, Lakewood, Littleton and Arvada.
Prices and rules change, so check with your building department before work starts.
