RTI SEALANT SPECIALISTS

BUILT FOR PERFORMANCE. BUILT FOR ACCOUNTABILITY.

RTI Sealant Specialists, Inc. is a commercial specialty subcontractor delivering joint sealant, waterproofing, expansion joint, firestopping, and protective coating systems on complex, schedule-sensitive projects.

With over 65 years of combined RTI experience and continuous operations dating back to the 1960s, RTI is a women-led, family-operated business built on long-term accountability, workforce stability, and relationship-driven execution.

RTI is trusted on projects where envelope failure is not an option and where clean close-out and first-time compliance matter.

HOW RTI APPROACHES PROJECTS

RTI partners with general contractors to reduce envelope-related risk before it becomes rework, delay, or post-handover defects.

This approach is built around:

• Early coordination and system understanding
• Clear scope definition and accountability
• Disciplined execution in high-exposure conditions

RTI’s role is not limited to installation, it is to support project teams in delivering predictable performance and smooth close-out on envelope-critical scopes.

WHAT SETS RTI APART

Reduced Envelope Risk

RTI installs systems designed to prevent leaks, failures, and long-term defects before they become claims or warranty issues.

Schedule Protection

RTI regularly executes late-stage and close-out scopes without disrupting inspections, occupancy, or turnover milestones.

First-Time Compliance

Firestopping and waterproofing scopes are installed to meet specifications and code requirements, supporting first-time inspection approval.

Clear Scopes, Fewer RFIs

RTI emphasizes defined inclusions and exclusions, minimizing gray areas, coordination issues, and downstream disputes.

EARLY-STAGE SYSTEM REVIEW & RISK IDENTIFICATION

RTI provides early-stage input by reviewing sealant, waterproofing, and expansion joint systems to identify constructability and exposure risks, particularly in high-risk areas such as:

• Below-grade conditions
• Elevator pits
• Movement and transition joints

Early review supports better sequencing, clearer scopes, and reduced downstream issues during construction.

WORKFORCE STABILITY & ACCOUNTABILITY

RTI’s workforce stability supports consistent execution and accountability across projects. This continuity allows RTI to deliver reliable results, maintain installation quality, and support repeat general contractor relationships over time.

RTI’s relationship-driven approach emphasizes long-term accountability, consistent field execution, and clean, predictable close-outs.

CONTINUITY & LEADERSHIP

RTI’s work continued under Ron Taraba, carrying forward the company’s focus on envelope-critical systems and long-term accountability.

Leadership later transitioned to Sherry Taraba, continuing the company’s direction as a women-led, family-operated business built on consistency and relationship-driven execution.

Today, RTI’s operations and project coordination are supported by:

• Lise Dollar – Operations and Preconstruction Coordination
• John Greevers – Field Operations
• Fernando Reyes – Field Superintendent

This structure supports alignment between preconstruction, field execution, and project delivery across schedule-sensitive work.
