Replace the Glass, Not the Entire Window
Save 50-70% by replacing only the damaged glass in your existing window frames. Hartness Glass offers fast, professional installation for cracked, foggy, or inefficient window glass.
When to Replace Your Window Glass
If your window frames are still in good condition, you can solve many common window problems by simply replacing the glass pane. Look for these key signs:
Cracked, chipped, or shattered glass
Foggy or milky appearance between panes, indicating a failed seal
Condensation trapped inside a double-pane window
Noticeable drafts or a sudden increase in energy bills
Distorted views or deep scratches that obstruct your vision

Glass Options for Every Home
Double-Pane Insulated Glass Units (IGUs)
Two panes of glass with a sealed air space between them. These are the standard for most modern homes and provide solid insulation without breaking the bank. When you call us, let's see if your existing frames can handle these units — it's often a straightforward swap that saves you hundreds.
Low-E (Low-Emissivity) Glass
A thin coating that reflects heat back where it belongs — outside in summer, inside in winter. Your energy bills will thank you. We don't do salesy pitches about revolutionary technology. This coating just works, and the numbers prove it.
Argon Gas-Filled Units
Instead of regular air between the panes, argon gas provides better insulation. It's denser than air and doesn't conduct heat as easily. Simple physics. Enhanced performance. No surprises on the bill.
Tempered Safety Glass
Required by code for doors and windows within 24 inches of the floor. When it breaks, it crumbles into small, relatively safe pieces instead of dangerous shards. We follow through on all safety requirements — your family's protection isn't negotiable.
Single-Pane Glass
Sometimes you need to match what's already there, especially in older homes or specific applications. We stock quality single-pane options when that's the honest alternative. Your glass guys will tell you straight if this makes sense for your situation.

Where we serve
Our expert technicians provide reliable window glass replacement for homeowners in The Woodlands, Spring, Conroe, and communities across the Greater Houston area.
When you call us from The Woodlands, we know the area. We've fixed foggy windows in those newer subdivisions where builder-grade double pane units start failing after 10-15 years. Same story in Spring — we see a lot of thermal seal failures in homes built in the 90s and 2000s.
Up in Conroe, we work on everything from older ranch homes to new construction. The weather patterns around Lake Conroe can be tough on windows, especially with those summer storms rolling through.
We also serve homeowners throughout Houston, from the inner loop out to the suburbs. Whether you're dealing with a broken window in Montrose or fogged glass in Katy, we bring the same honest approach. No surprises, just straight talk about what your windows need.
Your glass guys cover the whole metro area because window problems don't respect city limits. When you need reliable service without the sales pitch, let's see if we can help.
Window Glass Replacement FAQs
Glass-only replacement typically runs $150 to $400 per window, depending on size and glass type. That's a lot less than the $500 to $1,500 you'll pay for full window replacement. When you call us, let's see if your frame is in good shape — we don't do salesy upsells if glass replacement will do the job.
If your frame isn't rotted or warped, glass replacement costs about half what you'd pay for a complete window. We'll give you an honest assessment. Sometimes the frame really does need replacing, but most of the time it doesn't. Your glass guys believe in fixing what's broken, not selling you what you don't need.
Most single-pane glass replacements take 30 to 45 minutes per window. Double-pane units need 1 to 2 hours since we're dealing with sealed glass units. We measure, order your glass, then schedule installation — usually within a week. No surprises on timing.
Foggy windows mean the seal between glass panes has failed. You can't fix that seal — the glass unit needs replacing. But here's the thing: you don't need a whole new window frame. We replace just the sealed glass unit, which costs way less than what the big companies want to charge you for complete window replacement.
Single-pane is one piece of glass. Double-pane has two pieces with air or gas between them for insulation. Double-pane keeps your house warmer in winter and cooler in summer, which means lower energy bills. When we replace your glass, let's get it fixed with the right type for your home and budget.
