We back every glass shower door we install with a written, limited lifetime craftsmanship warranty. That's not a sales line. It's a real document covering defects in materials and workmanship for as long as you own your home. A new shower enclosure is a real investment, and you deserve to know exactly what's protected before you sign anything.
Not every warranty in this industry works the same way. Some skip the fine print on exclusions. Some leave you guessing what counts as normal wear versus a real defect. That gap matters most in coastal spots like Long Beach, where salt air adds extra stress on hardware finishes. Below, we break down what our warranty actually covers, and where it draws the line.
Your shower door works hard every day. Heat, steam, and constant water exposure put real stress on glass, seals, and hardware. Long Island's coastal air adds another layer on top of that, especially near the water. A written warranty tells you what happens if a defect shows up, not just what a salesperson promises.
We build our frameless shower doors, sliding doors, and corner shower enclosures with quality products and careful measuring. That reduces problems from the start. Still, no glass shower door lasts forever without some care on your end. Knowing what's covered, and what falls on regular maintenance, saves you frustration down the road.
Our glass warranty covers defects in materials and workmanship, meaning flaws that trace back to fabrication or installation. If a valid claim comes in, we repair or replace the defective piece at no charge to you. We just ask for proof of purchase with every claim.
What falls outside that coverage matters just as much:
We follow ASTM standards for blemishes too, meaning glass gets viewed from ten feet away in natural light. That rule applies only to work completed after January 1, 2016, and purchased directly through GCS Glass & Mirror.
Hinges, handles, brackets, and clamps take on real stress every time a door opens and closes. Our craftsmanship warranty covers defects in these parts at the time of install. What it doesn't cover is normal wear over the years. That includes hard water buildup, corrosion, and finish changes that come with daily use.
That distinction matters most in older Long Island homes, like many in Huntington. Hard water and aging plumbing speed up mineral buildup on fixtures there. Regular care keeps hardware looking sharp for longer. We recommend a non-ammonia glass cleaner, a squeegee after each shower, and good bathroom ventilation to slow that process down.
Our workmanship guarantee covers how we measure, align, anchor, and seal your shower door at install. That coverage lasts as long as you own your home as the original purchaser. It's non-transferable in most cases, and we spell out any exceptions in writing. A frameless shower is built to deflect water, not fully seal it out. We're upfront about that before you commit to one.
We measure every opening with laser-level precision, and our OSHA-certified team documents each step of the install. We're a family owned and operated business. We stand behind our work with clear, written terms instead of vague promises. Keep your proof of purchase on file. You'll need it if you ever file a claim.
If you ever need to file a warranty claim, contact your local GCS Glass & Mirror location directly. We'll ask for proof of purchase, then decide on a repair or a replacement. That decision sits with us, but we walk you through the process every step of the way.
Our Long Island office is located at 1347 Lincoln Avenue, Unit 7, in Holbrook, NY. You can reach us at (516) 400-2514 or by email at [email protected]. We built our name on transparent pricing and real customer service, not runaround phone trees.
Vague language is a warning sign. If a warranty doesn't spell out exclusions like breakage after install, tile damage from drilling, or size limits, be careful. Verbal promises don't hold up once a problem shows up.
If a company won't put warranty terms on paper, walk away. Compare written terms side by side when you review multiple proposals. A warranty that skips proof-of-purchase requirements or claims processes leaves you exposed later. We put every term in writing because we want you comparing us on facts, not promises.
You deserve a warranty you can read, understand, and rely on. When you request a proposal from us, you get our full written warranty terms up front. That covers materials and workmanship on your glass shower door, shower enclosure, or custom frameless shower door.
Reach out to our Long Island team at (516) 400-2514. Or stop by our Holbrook location at 1347 Lincoln Avenue, Unit 7. Schedule a consultation today, and get your warranty details in writing before you commit to a shower door installation.
Does GCS Glass & Mirror cover both parts and labor?
Our limited lifetime craftsmanship warranty covers defects in materials and workmanship for as long as the original purchaser owns the home. Proof of purchase is required for any claim, and we decide on repair or replacement.
How does Long Island's coastal air affect my hardware warranty?
Homes near the water, including areas close to Long Beach, face extra salt air exposure that speeds up wear on metal hardware. That kind of wear falls under normal use, so we recommend regular cleaning to help finishes last longer.
Will hard water in my area affect my warranty coverage?
Hard water buildup is common in Long Island towns like Huntington, where older plumbing can affect water quality. Our warranty treats hard water buildup as normal wear, not a covered defect. Routine cleaning is the best way to protect your glass.
What if my shower door was installed in an older home with uneven walls?
Older homes, including many in areas like Garden City, sometimes have settling that affects wall lines. Our workmanship warranty covers how accurately we measured and installed your door for your home's conditions at install.
