An egress window is a code-compliant emergency escape opening cut into a basement foundation wall, paired with a window well sized so a person can climb out. In Cheyenne the job is four connected pieces: the structural cut, the excavation, the well and its drainage, and the window itself. The drainage is the one most often underpriced, and the one most likely to cause a problem later.
What is actually involved
Assessment. We look at what is structurally above the proposed opening, what utilities run through that wall, how the ground outside falls, and where snow drifts against the house in winter. The last of those changes where we recommend cutting.
Excavation. Digging out the well location before the wall is opened, so the interior is never exposed longer than necessary. Access matters, a machine-accessible back yard is a different job from a three-foot side yard where everything moves by wheelbarrow.
The structural cut. A saw-cut opening through the foundation with appropriate support installed above. Concrete is removed cleanly rather than broken out, which matters for how well the window seals afterwards.
Well, drainage and cover. The well is set and backfilled, and drainage is connected so water leaving the well has somewhere to go. A cover keeps snow, rain and debris out while still permitting escape from inside.
Window, seal and finish. The unit is set, flashed and sealed, then finished on the interior. If the well is deep enough to require it, a ladder or steps go in. Then inspection.
What it costs
Cost is driven by five things, roughly in order of impact:
- Well depth. Deeper wells mean more excavation, more backfill, a larger well assembly and often a required ladder.
- Wall material and thickness. Poured concrete, block and thicker foundations all cut differently.
- Access. Whether a machine can reach the location, or whether spoil has to be moved by hand through a side yard.
- Drainage complexity. Whether there is somewhere for well drainage to discharge, or whether that has to be created.
- Window and well specification. A basic steel well and stock window against a larger composite well with an egress-rated cover.
Because these vary so widely by house, we quote after looking rather than over the phone. A bid given sight-unseen on an egress window is a bid that has assumed your best case. If this is part of a wider project, see basement bedrooms and egress.
When you need one
You need an egress opening whenever a basement room will be slept in, and it is worth installing when you are finishing a basement even if the immediate plan does not include a bedroom because it is far cheaper now than after the walls are closed, and it preserves the option of a legal bedroom later.
It is also worth considering purely for daylight. A basement with one properly sized window opening is a materially more pleasant space than one lit entirely by fixtures, and that difference shows up in whether the room actually gets used.
Cheyenne specifics that change the job
Wind decides where the snow goes, and in Cheyenne that is not a small factor. This is one of the windiest cities in the country, and sustained wind means snow does not fall evenly — it drifts, and it drifts hardest against whatever obstruction it meets. A window well on the lee side of a Cheyenne house can pack with drifted snow well beyond what the same well would collect in a calmer climate. That single fact is why we ask which side of your house drifts before recommending a location, and why the cover specification is not an afterthought here.
The soil is the second factor. Wyoming clay along this part of the Front Range holds water and moves with it, which means backfill around a new well needs care — loose backfill against a fresh foundation opening is a channel pointing straight at the thing you just cut. Proper compaction and a drainage path are what stop a correctly installed egress window from becoming the wettest part of your basement.
On the paperwork side, the exterior detailing depends on the applicable frost depth, and Cheyenne sources disagree — 36 inches, 42 inches and 42 to 48 inches all appear in print. We confirm the requirement for your address with the building department at permit stage rather than designing to a figure we found online.
How to choose a contractor for this
Ask every bidder the same five questions and the differences show up fast.
- "Are you pulling the permit, or am I?" If a contractor wants you to pull an owner-builder permit for work they are doing, the liability lands on you. That is the answer that should end the conversation.
- "What is my ceiling height after soffits?" Anyone who has not measured cannot answer, and the answer determines the layout.
- "What is in this price and what is an allowance?" Allowances are where a low bid hides. A flooring allowance set below what you actually want is a change order waiting to happen.
- "Who does the electrical and plumbing?" You want licensed trades and you want to know whether they are employees or subs.
- "What happens if you find water?" The honest answer involves stopping and repricing, not framing over it.
Get everything in writing, expect a payment schedule tied to milestones rather than a large deposit up front, and be suspicious of any bid that comes in far under the others. In a market this size, a number well below everyone else usually means something was left out rather than that someone found an efficiency.
Common questions
How much does an egress window cost in Cheyenne?
It depends far more on well depth, access and drainage than on the window itself. A shallow well on an accessible back lot is a very different job from a deep well in a narrow side yard. We give a written range after looking at the wall and the ground outside it.
Do I need a permit to install an egress window?
Yes. Cutting a structural foundation wall and creating a life-safety opening is permitted and inspected work, through the City of Cheyenne or Laramie County depending on your address.
Can I install an egress window myself?
The excavation is within reach of a determined homeowner. The structural cut is not, you are removing part of a load-bearing wall and it needs proper support above the opening. Getting that wrong is expensive in a way that is hard to reverse.
How long does installation take?
The window and well work itself is typically a matter of days once permitted, assuming reasonable access and no surprises behind the wall. Permit time sits in front of that.
Will it leak?
Not if the well drains and the cover fits. Leaks at egress windows in this area almost always trace back to a well with nowhere to send meltwater, or backfill that channels water toward the opening rather than away.
Does the well need a ladder?
Once a well passes a certain depth, a permanently attached ladder or steps is required so the opening is actually escapable. Your inspector will check it.
