Basement Window Replacement in Lawrence, KS

Basement window replacement in Lawrence takes out old steel, aluminum or wood basement windows that leak, rust or won't latch, and puts new vinyl windows in the same foundation opening. It's for homeowners who want a drier, tighter basement and windows that open and lock, and in most houses it's done without cutting any concrete.

What basement window replacement involves

Most basement windows are one of three kinds: a hopper that tilts in from the top, a small slider, or a fixed pane that doesn't open. We measure each opening and match the new window to it. On install day:

  • The old window comes out. Steel frames set into block or poured concrete are cut out without damaging the opening.
  • The new vinyl window is set, shimmed level and insulated around the edges.
  • The outside is sealed to the foundation, and the inside edge is trimmed or finished.

We look at the window well too. A well full of leaves and soil, or one that holds water, will leak through any window, new or old.

Signs your basement windows need replacing

  • Rust flaking off a steel frame, or holes rusted through
  • Soft or crumbling wood frames
  • Water stains on the wall below the window
  • Single-pane glass that drips with condensation
  • A latch that doesn't catch, so the window can be pushed open from outside
  • Cold air coming in around the frame

Why basement windows give out first

They sit at or below ground level, so they're up against damp soil, splashing rain and snow that piles into the window well all winter. Steel rusts, wood rots, and the single-pane glass in many older basements does almost nothing to keep the cold out. They're also easy to forget about until something leaks.

Same opening, not a bigger one

This service replaces windows in the openings you already have. If you're finishing the basement and need a bedroom window large enough to climb out of, that's an egress window: the foundation is cut wider, a bigger well is dug, and city building rules come into it. That's a different job, so we'll tell you right away if it's what your project needs.

What affects the cost of basement windows

  • How many windows you replace at once
  • Size and style: hopper, slider or fixed
  • Old steel frames cast into the wall, which take longer to remove
  • Repairs to crumbling block or mortar around the opening
  • Glass choices, such as obscure glass for privacy
  • Interior finishing if the basement is finished

Basement windows are smaller and usually cost less each than main-floor windows. More on pricing on thecost page.

Questions

Questions about basement windows

Can a basement window be replaced without changing the opening?

Yes, and that’s how most are done. The new window is made to fit the existing foundation opening, so there’s no concrete cutting. If the old frame is cast into the wall, it’s cut out carefully and the new unit is sealed to what’s left.

Are vinyl basement windows better than the old steel ones?

In most ways. Vinyl doesn’t rust, it insulates far better, and new units come with double-pane glass and a latch that works. The trade-off is a slightly thicker frame, so you can lose a little glass area compared with a thin steel frame.

Will a new basement window stop water coming in?

If water is getting in around a rusted or rotted frame, a new, sealed window fixes that. If the window well fills up because it doesn’t drain, or the yard slopes toward the house, a new window alone won’t solve it. We’ll tell you which one it looks like.

Can you make a basement window bigger while you’re at it?

Making an opening bigger means cutting the foundation and usually digging a larger window well. That’s an egress project, which is a separate job from replacing a window in the opening you have, and it isn’t part of this service.
