Scott DeWitt is the absolute 100% reason for my review being 5 stars instead of 3. He was a great installer, timely, respectful, genuine, and did the job right. Everything else unrelated to his work wasn’t all that impressive. Thanks Scott for the top tier work.

Had a glass block window put in my basement crawl space. They did a great job and they were quick and efficient. Would have them out anytime.

We discovered this company while visiting relatives in Ohio. Since our initial contact to replace two sets of French Doors, the entire process has been exceptional, simple, and the products are of the highest quality (while not the priciest in the market!) No hesitation to recommend this company to anyone.

Keith came out to review and quote our project. He was timely and informative. Then Thomas came out to install the windows - he was early (AWESOME), polite, completed the task quickly, and cleaned up after himself. We are happy with our windows too - they look great. We'll definitely work with this team again on our future window projects.

When investing in new windows for your home, understanding the warranty coverage is just as important as selecting the right style or material. A strong warranty protects your investment and ensures long-term performance, energy efficiency and peace of mind. At WMGB Home Improvement, we believe homeowners in Grand Rapids, MI, and the surrounding areas should be well-informed about window warranties before making a purchase.  

What Is a Window Warranty?  

A window warranty is a guarantee provided by the manufacturer or installer that covers defects in materials, workmanship and sometimes performance over a specified period. Warranties vary widely between manufacturers, so it’s essential to review the terms carefully. Some warranties cover only the glass, while others extend to the frame, hardware and even labor costs for repairs or replacements.  

Types of Window Warranties  

Manufacturers typically offer different levels of warranty coverage. The most common types include limited lifetime warranties, which cover the window for as long as you own the home, and prorated warranties, which decrease in value over time. Some companies also offer separate warranties for glass breakage, seal failure and installation workmanship. At WMGB Home Improvement, we partner with trusted manufacturers who provide comprehensive warranties, ensuring our customers receive lasting quality.  

Key Components of a Strong Warranty  

A robust window warranty should include coverage for glass seal failure, which can lead to fogging between panes, as well as defects in the frame and hardware. Additionally, it should address issues related to energy efficiency, such as gas leakage in insulated glass units. Labor coverage is another critical factor – some warranties only cover the cost of replacement parts, leaving homeowners responsible for installation fees. Always verify whether the warranty is transferable to a new homeowner, as this can add value to your property.  

Common Warranty Exclusions  

While warranties provide valuable protection, they often come with exclusions. Damage caused by improper installation, accidents or natural disasters is typically not covered. Modifications made to the windows after installation, such as painting or altering the frame, may also void the warranty. Additionally, some manufacturers require regular maintenance, such as cleaning and lubrication of moving parts, to keep the warranty valid. Our team at WMGB Home Improvement ensures proper installation and provides maintenance guidelines to help homeowners preserve their warranty coverage.  

The Importance of Professional Installation  

Even the best window warranty can be voided if the installation is not performed correctly. Poor installation can lead to air leaks, water infiltration and operational issues, which may not be covered under the manufacturer’s warranty. That’s why choosing an experienced and reputable contractor like WMGB Home Improvement is crucial. Our certified installers follow industry best practices to ensure your windows perform as intended and remain protected under warranty.  

How to Make a Warranty Claim  

If an issue arises with your windows, the first step is to review your warranty documentation to confirm coverage. Contact the manufacturer or installer with details about the problem, including photos if necessary. Many companies require proof of purchase and installation records, so keeping these documents in a safe place is essential. At WMGB Home Improvement, we assist our customers throughout the claims process, making it as seamless as possible.  

Choosing the Right Windows and Warranty  

When selecting new windows, consider both the product quality and the warranty terms. High-performance windows from reputable manufacturers often come with stronger warranties, reflecting confidence in their durability. We help homeowners in Grand Rapids and western Michigan compare options, ensuring they choose windows that offer the best combination of performance, aesthetics, and warranty protection.  

Final Thoughts  

At WMGB Home Improvement, we prioritize transparency and quality, offering professional installation and guidance to help homeowners make informed decisions. Investing in high-quality windows with a strong warranty not only enhances your home’s comfort and energy efficiency but also provides long-term value. Let WMGB Home Improvement help you navigate the process with confidence.
