Basement Window Enlargement in Minot, ND

If a basement wall already has a window where you want the bedroom, enlarging that opening is often simpler than starting fresh. The top of the opening usually stays where it is and the concrete below gets cut out, which drops the sill and makes the opening taller. Sometimes it gets wider too.

When is enlarging the right call?

The existing window sits on the wall where the bedroom will be
There's open ground outside, not a driveway, patio or deck footing
The existing header or lintel is sound and wide enough, or can be reinforced
The interior side is clear of plumbing, ducts and wiring below the old sill

How does it work?

The old window and the small existing well come out.
The installer digs deeper outside to make room for a full-size well.
The concrete below the old opening is cut away to the new sill height, and the sides are cut if the opening needs to be wider.
A new window goes in, sized to give at least 5.7 square feet of net clear opening with the sill no higher than 44 inches off the floor.
A new well of at least 9 square feet goes on, with drain rock and a ladder if it's deeper than 44 inches.

Why not just put a bigger window in the same hole?

Because most original basement openings are too short. A typical old hopper or slider opening is a foot or two tall. Even with a casement that opens fully, the clear opening needs at least 24 inches of height and 5.7 square feet of area, and most old openings can't give you both without cutting.

Things to ask about older Minot houses

Older foundations can hide surprises: earlier patches around the window, or wiring and pipes run right under the old sill. Ask the installer to look from inside before the price is final, and to explain how they'll support the wall above a wider opening.

Is a permit needed?

Minot reviews residential plans for compliance before it issues permits for new homes, additions and renovations. Enlarging a foundation opening changes the structure, so check with Building Safety before work starts.

We don't give prices. Each installer prices the job after measuring the wall, checking the soil and seeing what sits outside that part of the foundation, so a number over the phone is only a ballpark until then.

Common questions

Is enlarging cheaper than a new opening?

It can be, since part of the hole already exists, but it depends on the wall, the digging and how much reinforcement is needed. Only an installer who has seen the wall can say.

Can a small window simply be swapped for an egress model?

Rarely. Most old basement openings are too short to reach 24 inches of clear height and 5.7 square feet of clear area without cutting the concrete.
