A typical glass shower door warranty covers three layers: the installer's workmanship on labor (commonly 1 year), the glass manufacturer's coverage on the panels, and the hardware manufacturer's standard terms on hinges, handles, and seals. The terms are industry-standard for a local glass shop, and the differences between installers usually show up not in the WHAT but in the HOW: how quickly service requests are returned, and whether the original install team returns to make adjustments. This guide walks through what's covered, what's not, how long the coverage runs, what to ask your installer before you sign, and how Moffat Glass handles warranty service across Larimer and Weld County. For the full residential and commercial terms, see the full Moffat warranty terms.
A glass shower door warranty typically covers the installer's labor on adjustments and operational issues (workmanship), the glass manufacturer's terms on the panels themselves, and the hardware manufacturer's terms on the hinges, handles, and seals. These three layers stack together and each is a separate conversation.
Installer workmanship covers the labor side. During the workmanship period, the installer returns at no charge to address adjustments and operational issues on the glass and hardware they installed. In practice that means:
Glass manufacturer coverage runs on the panels themselves. Tempered glass, frosted glass, textured patterns, and low-iron glass each carry the glass manufacturer's standard warranty terms. Terms vary by manufacturer; the panel typically carries a defect warranty (delamination, manufacturing-flaw breakage) for a period set by the manufacturer.
Hardware manufacturer coverage runs on the hinges, clips, sweeps, seals, handles, and finishes. Premium finishes (matte black, brushed nickel, polished chrome, gold, brass) follow the hardware manufacturer's standard terms with no separate installer-side coverage extension. For the specifics of how all three layers apply on a residential install, see custom frameless shower doors.
That is the typical scope. What it does NOT cover is a separate conversation.
Standard glass shower door warranty exclusions cover the same categories across the industry: weather extremes, hard water buildup, improper cleaning, pet damage, third-party modifications, normal wear on finishes, and acts of God. Each pairs with a practical "how to protect your install" beat.
Knowing what's NOT covered is half the conversation. The other half is how long the coverage runs.
Most glass shower door warranties run 1 year on installer workmanship, with glass and hardware manufacturer terms layered on top. Insulated glass units, where used, carry a 10-year pro-rated manufacturer warranty. Moffat's published durations match.
Residential workmanship duration. 1 year on labor from the date of installation. Scope is adjustments and operational issues on the glass and hardware originally installed.
Commercial workmanship duration. 1 year from the date of project completion. The framing difference (completion rather than installation date) matters for property managers and general contractors working through phased project closeouts; otherwise the commercial scope mirrors residential.
IGU (insulated glass unit) duration. 10-year pro-rated manufacturer warranty, with labor not included. "Pro-rated" means the manufacturer's replacement coverage scales down across the 10-year window: full coverage in the early years, decreasing annually. IGUs are uncommon on shower doors themselves but appear on adjacent glass (bathroom windows, partition windows in a wet room). For the complete IGU warranty terms, see the Warranty page.
Glass and hardware manufacturer duration. Terms vary by manufacturer. The panel carries a defect warranty for the period set by the manufacturer; hardware (hinges, handles, seals, finishes) follows the hardware manufacturer's standard terms. The installer does not extend additional coverage on top of these pass-through terms.
The duration stack is one half of the conversation. The other half is knowing what to ask before you sign.
The terms above are the standard stack across the industry. What separates one installer from another is how transparently the answers come back before the contract is signed. A homeowner shopping a custom shower can use these six questions to vet an installer's warranty position.
A shower door consultation is the natural moment to walk through these questions against the actual room.
Moffat Glass responds to every warranty request within 2 business days, and the same in-house Moffat crew that fabricated and installed the shower is the team that returns to perform warranty service.
Same team, never subcontracted. The in-house crew that built the install is the team that returns to perform warranty service. Warranty calls are scheduled into the workflow alongside new installs, which protects the quality of both.
Multiple contact channels. Phone, web contact form, email at sales@moffatglass.com, or walk-in at any of three Northern Colorado locations (Evans HQ, Loveland, Fort Collins).
What to have ready before contacting. Approximate install date, brief description of the issue, and photos if available. That keeps the first conversation focused on scheduling the service visit rather than tracking down missing details.
Honest service-window disclosure. Moffat does not maintain a rush-service tier or run service calls outside normal business hours, and we publish that openly. That commitment is the published standard, every time. For more residential coverage questions, see the residential FAQ, or review Moffat's warranty service process on the Warranty page.
How long is a glass shower door warranty?

Insulated glass units, where used, carry a 10-year pro-rated manufacturer warranty. Moffat Glass matches the 1-year workmanship duration in Northern Colorado. Request a quote for written terms.
What does a shower door warranty cover?
A shower door warranty covers the installer's workmanship on labor plus the glass and hardware manufacturer terms. Workmanship typically covers adjustments and operational issues (door alignment, hinge operation, loose hardware) on the glass and hardware originally installed. Manufacturer terms vary by manufacturer and product line. Schedule an on-site measure to review.
What is not covered under a shower door warranty?
Standard exclusions are consistent across the industry: weather, hard water, improper cleaning, pet damage, third-party modifications, normal finish wear, and acts of God. Each pairs with a homeowner-care responsibility (squeegee after every shower, mild non-abrasive cleaners only, periodic torque checks on hardware). Moffat publishes the full exclusion list openly as care guidance.
Does hard water damage void a shower door warranty?
Yes. Mineral buildup from hard water is not covered by any standard glass shower door warranty. Northern Colorado water is mineral-heavy, so squeegee discipline after every shower is the care commitment. A factory coating applied at install slows buildup significantly. Schedule a consultation to discuss the spec.
How quickly will Moffat respond to a warranty request?
Moffat responds to every warranty request within 2 business days, residential and commercial.
