Expert Glass Block Installation
Owner-operated craftsmanship for windows, walls, and showers across Denver and the Colorado Front Range. Clean lines, lasting installs, and real attention to detail.
Who we are
Aspen Glass Block is an owner-operated business built on a simple idea: a glass block install should look as good up close as it does from the street—and still be watertight in twenty years.
For more than 20 years we've set glass block windows and walls throughout the Denver area and all along the Front Range. From a single basement window to a full-height feature wall, every joint is tooled by hand and every panel is set true. We handle traditional mortared block, modern silicone-fabricated panels, and repairs to failing acrylic block—so you get the right method for your home, not just the one we happen to sell.
What we do
Every project starts with how you want it to look and where it has to live. We'll walk your space, talk through the options, and recommend the approach that fits.
The time-tested method: solid block laid in mortar for windows and walls that shrug off weather and deliver decades of privacy and light. Ideal for bathrooms, basements, and any opening that needs to last.
Pre-assembled panels joined with clear silicone instead of mortar—thin, crisp grid lines and a bright, contemporary look. A great fit for modern remodels and showers where you want the glass to be the detail.
Cloudy, cracked, or fogged acrylic block windows? We repair and replace failing acrylic units—restoring clarity, security, and a clean finish without redoing the whole opening.
Where it works
Glass block earns its keep almost anywhere a standard window feels too exposed or too plain.
Daylight in the shower without sacrificing privacy—mortared or silicone-fabricated to suit your tile.
Secure, hard-to-breach windows that still let light into lower-level rooms and egress wells.
Street-facing, side-yard, and stairwell openings that stay bright but keep the view to yourself.
Freestanding partitions and gentle curves that divide a space while keeping it open and luminous.
Full-height glass block panels that turn a stair, foyer, or façade into the highlight of the room.
Storefronts and older buildings where glass block needs to match an era—or bring one back.
Selected work
Interiors and exteriors, old and new—clear, textured, and colored block, set for light and privacy.
Why glass block
Daylight floods in while the textured glass keeps sightlines—and neighbors—out.
Solid block set in mortar is far harder to break through than a standard pane.
Insulating hollow block helps hold temperature and cut drafts around old openings.
No sashes to rot, no screens to replace—just an occasional wipe-down.
Clear, wave, and icescape textures—and colored block—to match any style.
Done right the first time, a glass block install can outlast the wall around it.
