Glass Block Window Installation in Minneapolis, MN

We install glass block windows for Minneapolis, MN basements: sturdy, private, and set in mortar to last. If you searched for glass block window installation minneapolis mn, you likely have an old basement window that leaks air, fogs up, or feels flimsy, and you want it replaced with something solid. We measure the opening, build the block panel to fit, and seal it against the weather. You get natural light, privacy, and a window that stands up to Minneapolis winters. Our glass block installations combine durability with the aesthetic and functional benefits that modern homeowners expect.

What Our Glass Block Window Installation Covers

Glass block works best where you want light and strength but do not need the window to open. Here is the work we handle:

• Basement window replacement with glass block. We remove an old, drafty basement window and mortar in a glass block panel sized to your exact opening. Custom sizes are standard, since older Minneapolis foundations rarely match stock dimensions.
• Glass block for finished basements. If you are finishing your basement, block windows give you daylight without giving neighbors a view of your rec room or laundry.
• Basement window blocks for privacy and security. Glass block is thick and set in mortar, so it resists break-ins far better than a thin single-pane sash.
• Small basement window installation. Narrow openings above grade or inside a window well are a common fit for glass block. We build panels for small openings that other installers pass on.
• Mortar and sealing work. Every panel gets professional mortar joints and exterior sealing so water stays out of your foundation wall.

One important note: glass block does not open, so it does not meet the bedroom egress requirement. If the room is a bedroom or will become one, you need a basement egress window instead. We install those too, and we will tell you straight which one your room needs before any work starts.

How Glass Block Window Installation Works

1. Measure and quote

You reach out, we talk through which windows you want replaced and what the rooms are used for. We check whether glass block fits code compliance for each opening or whether an egress window is required. Then we measure and give you a real quote, free, with no vague ranges.

2. Remove the old window

On install day we pull the old sash and frame, clean the opening down to sound masonry, and check the sill for rot or crumbling mortar. If the opening sits inside a window well, we clear it and inspect the well while we are there.

3. Set the glass block panel

We build or set the block panel to fit your opening, mortar it into the foundation wall, and tool the joints. A tight mortar bed is what keeps the panel solid for decades, so we do not rush this step.

4. Seal and clean up

We seal the exterior perimeter against water and drafts, wipe down the block, and haul away the old window. You are left with a finished opening, inside and out, and nothing to paint or maintain.

What Affects the Price

No two basements price the same, and we will not pretend otherwise. The honest factors:

• Opening size and count. A single small basement window costs less than four full-width openings. Doing several windows in one visit usually lowers the cost per window.
• Condition of the existing opening. Crumbling sills, rotted bucks, or damaged masonry need repair before block goes in.
• Access. Windows inside a deep window well, behind landscaping, or in a tight side yard take more time than an open, above-grade wall.
• Vent or dryer options. Some homeowners add a small vent block or dryer vent in the panel, which changes the build.
• Whether egress is required. If the room is a bedroom, glass block is off the table for that opening and you are pricing basement egress window installation instead. Egress window installation cost runs on different factors, like digging the well and cutting the foundation, and we quote that separately.

Pricing varies by project, so the useful number is the one for your house. Ask for a free quote and we will measure your openings and give you a firm figure.

Glass Block Window Installation Questions, Answered

Do glass block windows meet egress window requirements?

No. Glass block does not open, so it cannot serve as an egress window for a bedroom or sleeping room. Egress window requirements call for an opening large enough for a person to climb out, and code sets minimum egress window sizes for that opening. If your basement room is a bedroom, you need a basement egress window there, and glass block can still work for the other openings.

Why choose glass block over a regular basement window?

Glass block gives you light, privacy, and strength in one panel with no moving parts to fail. It will not rot, it is hard to break through, and mortared block seals out drafts better than an aging sash. It is a strong fit for laundry rooms, storage areas, bathrooms, and finished basement spaces where you do not need the window to open.

Can you match odd-sized openings in older Minneapolis homes?

Yes. We build glass block panels in custom sizes, so an out-of-square or nonstandard opening is normal work, not a problem. Older foundations rarely match stock window dimensions, which is exactly why block panels get built to fit the opening rather than the other way around.

Do glass block windows leak or fog up?

A properly mortared and sealed glass block panel should not leak. Each block is a sealed unit, so it does not fog between panes the way a failed double-pane window does. The key is solid mortar joints and exterior sealing, which is the part of the job we take the most time on.

Can I get ventilation with a glass block window?

Yes, a small vent block can be built into the panel. It gives you some airflow for a laundry room or bathroom while keeping the privacy and strength of the block. Tell us during the quote which rooms need ventilation and we will plan the panels around it.

What if I need an egress window instead?

We install those too. If your project involves a bedroom, a casement egress window with a proper window well is the code-compliant route, and we can quote glass block and egress work in the same visit. You get one plan for the whole basement instead of piecing it together.
