Cracked patio door? Foggy slider? We'll make it like new. Mission Glass repairs and replaces glass in all types of sliding doors — patio sliders, interior glass doors, and multi-panel systems — across San Antonio and Bexar County.
Sliding glass doors are one of the most popular features in San Antonio homes — they connect your living space to the patio, let in natural light, and provide Hill Country views. But when the glass cracks, fogs up between the panes, or shatters, that beautiful door becomes a security risk and an energy drain. Texas code requires tempered safety glass in all sliding doors, meaning replacement glass must meet specific safety standards.
Mission Glass handles sliding door glass for homes across San Antonio — from larger properties in Timberwood Park and Shavano Park to condos and townhomes closer to downtown. In most cases, we can replace just the glass panel without replacing the entire door — saving you significant money. We source tempered glass in clear, tinted, and Low-E options to match your existing setup.
The most common sliding door type. Single and double-panel patio sliders with tempered glass replacement in standard and custom sizes.
Interior sliding glass doors for bedrooms, offices, and room dividers. Clear, frosted, and patterned glass options available.
Large multi-panel sliding door systems with multiple glass panels. We replace individual panels or complete sets.
Upgrade standard glass to laminated safety glass for increased security. Laminated glass holds together when broken, deterring break-ins.
The most common sliding door glass problems we see in San Antonio homes: cracked or chipped panels from impact, foggy glass between double-pane insulated units (seal failure from Texas heat cycling), broken rollers causing the door to stick and stress the glass, security concerns from weakened or single-pane glass, and condensation buildup from failed weatherstripping. Don't ignore a crack in sliding door glass — Texas heat causes cracks to spread quickly, and tempered glass can shatter suddenly once compromised.
All sliding door glass in Texas must be tempered per building code. Tempered glass is 4-5 times stronger than standard annealed glass and breaks into small, rounded pieces instead of dangerous shards. Mission Glass uses only code-compliant tempered glass for all sliding door replacements. If your current sliding door has non-tempered glass (common in older homes), we can upgrade it to tempered during replacement — bringing your door up to current safety standards.
"Our patio slider in Timberwood Park got hit by a baseball — cracked the whole panel. Mission Glass came out, measured, and had new tempered glass installed within the week. Clean work, fair price, no drama."
"Two of our sliding doors in Shavano Park had gone foggy between the panes. Mission Glass replaced both glass panels in one visit without touching the frames. Looks brand new and we're saving on AC already."
Sliding glass door repair cost varies by panel size, glass type, and whether the frame needs attention. Single-panel glass replacement is typically less expensive than full door replacement. Mission Glass provides free on-site estimates.
In most cases, yes. If the door frame, track, and hardware are in good condition, we can replace only the glass panel — saving you the cost of a complete door replacement.
Most sliding door glass replacements take 2-3 hours on-site. We source the glass (usually 1-5 business days depending on size and type), then schedule installation at your convenience.
We specialize in glass replacement and repair. For new door installations that involve framing or structural work, we recommend working with a general contractor and can handle the glass component of the project.
Texas building code requires tempered safety glass in all sliding doors. Tempered glass is 4-5 times stronger than standard glass and shatters into small, blunt pieces if broken — reducing injury risk.
