When making business window replacement investments, property owners and managers will prioritize design, energy efficiency, and installation timelines—but there’s one extremely critical detail easily overlooked: the warranty. A good window replacement warranty isn’t a luxury; it’s a vital protection of your investment.
At Best Offer Glass, our customers should be aware of the warranties covered and why. This blog explains the importance of commercial window installation warranties, the types to be aware of, and what to look for in a trustworthy warranty.
Commercial windows are a significant capital expense. Whatever the situation may be when retrofitting an office complex, storefront, hotel, or apartment building, you may have to pay for expensive repairs because of leaks, seal breakdowns, or frame failure if not warranted.
This is why a good warranty is necessary:
Windows are not a short-term fix; they’re built to last decades. A guarantee will be that you won’t pay upfront if the product or artistry is faulty and breaks down prematurely.
A manufacturer or installer who offers a good warranty is standing behind their product and labor. It’s a vote of confidence in quality, durability, and long-term performance.
For property managers and owners, warranties put a cap on liability and risk in commercial properties, especially in more than one location or unit.
Transferable warranty properties become more desirable to potential buyers or lessees as they give more extended protection and reduced maintenance risk.
Understand the type of warranties offered for commercial window installations so you can identify potential gaps and make informed buying decisions.
This is the broadest type of warranty offered by the window manufacturer. It usually covers:
Typical span: 10 to 20 years
Transferability: Occasionally transferable to new building owners
Provided by the installer, this guarantee ensures that there was no mistake in the installation process—one of the significant reasons behind premature window failure.
What it covers:
Typical period: 1 to 5 years, depending on contractor and project size
Some manufacturers offer a more extended warranty for accidental glass breakage, a valuable add-on for high-traffic or break-in-prone commercial applications.
Note: This is typically an optional or add-on warranty and may be dependent on registration.
Some large commercial projects include custom warranties negotiated into the contract by some vendors. These roll labour and product coverage into a single blanket policy.
Not all warranties are equal. When considering or comparing warranties from various providers, this is what to watch for:
The warranty must clearly outline what is covered and for how long. Ambiguous language gives too much scope for denial of coverage.
Watch for:
Even the best window won’t work correctly if it’s installed poorly. A warranty on artistry is essential—especially on commercial buildings where any failure can be costly.
Best Offer Glass offers a guarantee of installation on all commercial work we do, providing you with confidence from the start.
Can the warranty be transferred to a new property owner or tenant? This is especially suitable for investment properties or buildings that need to be sold.
Look for:
Seals in insulated glass units (IGUs) will ultimately fail, especially in coastal or humid exposures like San Francisco. Seal failure can lead to fogging and reduced energy performance.
Best warranties guarantee 10–20 years of seal protection.
Standard exclusions include damage caused by earthquakes, hurricanes, and other natural disasters; vandalism; misuse; and unauthorized modification. Be sure to read the fine print so you understand what is not covered.
