Services
Custom Shower Doors
Craft premium frameless and semi-frameless shower enclosures using tempered 3/8-1/2" glass. Our expert installers ensure perfect fit and function while maintaining aesthetic appeal. We specialize in custom configurations including steam showers and specialty glass options like 24kt gold-plated finishes. All installations include professional measurement, templating, and warranty protection.
Polymer Coating Application
Apply patented Teflon-based polymer sealant to shower glass surfaces. This protective coating prevents etching from hard water and soap scum buildup while reducing maintenance requirements by up to 70%. The durable treatment lasts over three years and maintains glass clarity while allowing regular use of non-abrasive cleaning methods.
Custom Cabinet Glass
Provide patterned, etched, and colored glass options for kitchen and display cabinets. With over 30 sample options available, we help clients select appropriate opacity levels from subtle textures to fully obscure patterns. Our team installs finished glass panels in existing frames, typically completing projects within 3-5 business days.

Our technicians address seal failure, track misalignment, and weatherstripping issues while maintaining energy efficiency standards. Each repair includes functional testing and hardware adjustment to ensure smooth operation and security.
