Egress Windows in O'Fallon, Missouri

Many O'Fallon basements have only small hopper windows high on the wall. They do not meet egress size, and they barely light the room. Replacing one with a full egress casement changes both safety and how the space feels.

O'Fallon homes and this kind of project

Our first visit for an egress window in O'Fallon is spent on the outside of the wall for gas, electric, AC lines and downspout drains, and the framing load above, which tells us how two-stories and atrium ranches from the 1985 to 2010 boom were put together.

The housing stock here: mostly 1985 to 2010 production two-stories, ranches and atrium ranches, with older ranches and bungalows near the original town center.

Poured eight-inch walls from these decades cut cleanly with a wet saw.

Foundations and basements in O'Fallon

Full basements are nearly universal. Atrium ranch plans, popular here, have a wall of windows at the lower level that makes for an excellent finished space. Many basements were finished by owners in the 1990s without permits, so we often find work that needs correcting.

Homes built in O'Fallon between the late 1970s and the 2000s nearly all have full poured basements, and a large share were finished once already by an owner or handyman, often without permits. We open a few walls before quoting, because what is behind them decides whether this is a refresh or a rebuild.

What is included

Our O'Fallon egress scope includes utility locates, permit, excavation, saw-cutting, header and buck, a casement window sized to code, a well with ladder if required, stone and drain, backfill, grading away from the well and interior drywall returns and trim.

We take on egress window work across O'Fallon, from Wyndgate to the Highway K corridor and old town O'Fallon.

What we watch for

Builders in O'Fallon often ran the AC lineset, gas meter or a downspout drain right where the best egress location would be. We walk the outside of the wall first, because moving a window two feet on paper is free.

Site logistics matter: O'Fallon has established subdivision lots with fenced rear yards, so we agree with you where an excavator, a concrete cutter and carpenters will park, store material and carry out debris.

Permits and approvals in O'Fallon

For an egress window at a O'Fallon address, the paperwork goes to the City of O'Fallon building division. Expect a building inspection of the opening, header and well.

Exterior work in O'Fallon can also involve neighborhood HOAs and, in WingHaven, a master association, and we put that package together for you.

Schedule and getting to you

Plan on two to four working days on site of site work for an egress window in O'Fallon, once permits and materials are in hand.

From our Wentzville base, O'Fallon is fifteen minutes or so east on I-70 or I-64. That is close enough that your project lead can stop by most days.

What moves the price in O'Fallon

We price egress windows in O'Fallon from a site visit, not a square-foot figure. These are the items that change the number.

  • Well type: galvanized steel, composite stepped wells that look like stone, or site-built timber or block.
  • Drain connection method.

More detail

Our step-by-step method for this work, and the factors that move its price, are laid out on the main egress windows page. More about the area is on our O'Fallon page.

Egress Windows in O'Fallon: common questions

How long does an egress window take in O'Fallon?

Two to four working days on site once the permit is issued and locates are marked, plus interior trim. In O'Fallon, permit review by the City of O'Fallon building division and material lead times affect the start date more than our calendar does.

Do I need approval beyond a permit for an egress window in O'Fallon?

Possibly. In O'Fallon you may be dealing with neighborhood HOAs and, in WingHaven, a master association. City or county approval and private approval are separate, and we prepare both submittals and wait for written approval before ordering materials.

Will cutting the foundation weaken my house?

Not when it is laid out and headered correctly. Foundations are cut for windows and doors routinely. The risk comes from cutting under a concentrated load without checking, which we do not do.
