FAQ

Everything you want to know about glasswork and our services.

Why choose Bel Pre Glassworks?

We put our customers' needs first with quality products, neat installations and attentive customer service, while maintaining competitive pricing. Our on-site specialized machinery lets us do the majority of our own fabrication, which means better quality control and orders expedited in a timely fashion.

Do I need an appointment to visit the showroom?

Yes — please contact our office to schedule an appointment.

Do I need a measure appointment to get pricing?

No. If you are simply looking for pricing, provide your information by email and we will give you an approximate cost.

What has to be finished before you measure?

For a shower enclosure, all tile work must be complete, including the threshold, installed with a slight pitch into the shower so water drains in rather than out. For mirror work, any trim, tile or countertops the mirrors will rest on must be installed first.

What happens on the day you measure?

If you are ready to proceed, we provide the proposal on site; sign it and leave a 50% deposit and the order starts. Otherwise we email a copy and start when the signed proposal and deposit come back — Visa, MasterCard, Discover, American Express or check.

What are your lead times?

Lead times start the day we receive your approved order (signed proposal and deposit) and vary with the scope of work. Call the office for specifics.

What is the warranty on frameless shower installations?

One year on parts and labor. Our standard hinge manufacturer, C.R. Laurence, warrants its hinges for three years; Portals Hardware hinges, available at additional cost, carry a lifetime warranty.

What should I use to clean my mirrors?

An ammonia-free glass cleaner — ammonia can eat away at the backing of a mirror.

How do I avoid water spots on shower glass?

Regular glass is porous, so standing water can embed and leave a permanent spot. We offer the Amaz water-stain remover, and for a long-term answer, ShowerGuard glass, which is permanently sealed during manufacturing.

What are tempered and low-iron glass?

Tempered glass is safety glass required by building code in applications such as shower enclosures. Low-iron glass has less of the green tint regular glass shows at the edges; we use Starphire by Vitro, considered the clearest glass available.
