Frequently Asked Questions
What types of residential glass services do you offer?

If you have cracked or foggy windows, we can replace the glass units without needing to install entirely new frames. Our team is dedicated to providing quality glass in Spencer, MA for every homeowner.
How does your mobile auto glass service work?
Our mobile service is designed for your convenience, operating Monday through Friday from 8:00 AM to 3:00 PM. We can come to your home or workplace to handle windshield repairs and full replacements. This service makes it easy to access quality glass without disrupting your busy schedule. We bring all the necessary tools and materials directly to your location to ensure your vehicle is safe and road-ready as quickly as possible.
Can you help me with my auto insurance claim?
Yes, we work with all major insurance carriers to make the process as seamless as possible for our customers. In Massachusetts, many glass policies have a zero-deductible clause, meaning your repair or replacement might cost you nothing out of pocket. We take pride in installing quality glass in Spencer, MA while handling the paperwork on your behalf. Simply give us your policy information, and our office staff will coordinate with your agent to file the claim.
What is ADAS recalibration and do I need it?
Modern vehicles often feature Advanced Driver Assistance Systems, which include cameras and sensors mounted behind the windshield. When a windshield is replaced, these systems must be recalibrated to ensure safety features like the lane-keep assist function work correctly. We utilize advanced technology to provide quality glass in Spencer, MA that remains fully integrated with your car’s safety tech.
What options are available for custom shower doors?
We specialize in both framed and frameless shower enclosures tailored to fit your specific bathroom layout. Our technicians use heavy-duty tempered glass and premium hardware to create a luxury look that lasts for years. When looking for quality glass in Spencer, MA for a bathroom renovation, our custom designs offer the perfect blend of style and durability. We provide free estimates to help you choose the best configuration for your space and budget.
Do you provide glass services for commercial businesses?
Absolutely, we offer comprehensive commercial services, including storefront installation, door repairs, and architectural glass. We understand that a broken window or door can impact your business operations, so we prioritize timely and professional service. Local business owners trust us for quality glass in Spencer, MA because we focus on safety and aesthetic appeal.
How do I know if my windshield can be repaired instead of replaced?
Generally, if a chip or crack is smaller than a quarter and not directly in the driver’s line of sight, a repair may be possible. Repairing a small chip early prevents it from spreading and saves you the cost of a full replacement. Our technicians evaluate every vehicle to ensure we provide the safest and most cost-effective quality glass in Spencer, MA for your specific situation. We use high-grade resins to restore the strength of your windshield.
What are the benefits of custom mirrors in a home?
Custom mirrors can significantly brighten a room and create the illusion of more space, making them ideal for bathrooms, gyms, or hallways. We cut mirrors to any size and offer various edging options, such as polished or beveled edges, to match your decor. We are the premier choice for quality glass in Spencer, MA when it comes to decorative and functional mirror installations.
Are your technicians certified and experienced?
Yes, Guaranty Glass & Mirror has been locally owned and operated since 1993, and our team consists of highly skilled glaziers. We combine decades of experience with modern techniques to deliver superior results on every project.

Do you offer window tinting for vehicles?
We provide professional automotive window tinting services that help reduce glare, block UV rays, and keep your car's interior cool.

When you are searching for quality glass in Spencer, MA and want to enhance your vehicle’s appearance, our tinting specialists can help. We ensure that all tint applications comply with local regulations while providing a sleek, bubble-free finish for your car.
What should I do if my home window is broken?
If a window in your home is shattered or cracked, you should contact us immediately for an estimate. We can often replace just the glass pane, which is much more affordable than replacing the entire window unit. We provide reliable and durable quality glass in Spencer, MA to restore the security and energy efficiency of your home.
