NYC DOB-COMPLIANT WORK IN PROGRESS SIGNS
Meet DOB Compliance With Premium Site Wraps
Under the NYC Department of Buildings (DOB) Chapter 33 administrative code, all active construction sites with temporary fencing are legally required to display official 'Work in Progress' signs. These signs must follow strict guidelines, including specific dimensions, a mandatory blue color background, and clear contractor info.
At Signs River, we fabricate official NYC DOB-compliant Work in Progress signs and high-definition blue fence wraps. Our team ensures that your signs contain all required legal elements: project description, rendering box, contractor license, DOB permit numbers, and anticipated completion dates.

Glass Safety & Thermal Compatibility
Applying standard vinyl graphics to insulated double-pane glass or tinted commercial windows can introduce thermal stress. If a film absorbs too much solar radiation, it can cause the glass unit to experience rapid heat absorption and expansion, risking cracking or seal failure.
At Signs River, we perform meticulous thermal stress analysis during our site survey. We determine the exact glass configuration (clear, annealed, tinted, Low-E, tempered) and exposure index (south-facing, shaded) to match the correct polymeric or perforated film. We fully back all our glass installations with a zero-crack safety guarantee.
