High-Rise Caulking FAQ

Question 1

What safety certifications do your high-rise caulking technicians have?

Accepted Answer

Our high-rise caulking specialists hold IRATA (Industrial Rope Access Trade Association) or SPRAT (Society of Professional Rope Access Technicians) rope access certifications, aerial lift operation licenses, and comprehensive fall protection training. All technicians maintain current OSHA 10/30 certifications and undergo quarterly safety training specific to high-rise building envelope work.

Question 2

How do you access different areas of high-rise buildings?

Accepted Answer

We use multiple access methods based on building design and project requirements: rope access (descent systems), boom lifts (up to 185 feet), scissor lifts for lower levels, building maintenance units (BMUs/window washing rigs), swing stages for facades, and suspended scaffolding. Method selection depends on work scope, site conditions, and optimal efficiency for each project.

Question 3

What types of sealants do you use for high-rise applications?

Accepted Answer

We specify premium sealants from DOW, Sika, Pecora, and Tremco based on joint requirements: structural silicone for glazing systems (ASTM C920), high-movement polyurethane for expansion joints (+/-50% movement capability), fire-stop sealants for rated assemblies, and specialized systems for curtain wall, precast panel, and window perimeter applications.

Question 4

Can you work while the building remains occupied?

Accepted Answer

Yes, we specialize in occupied building work using proper safety barriers, coordination with building management, tenant notification protocols, and minimal-disruption techniques. We can schedule exterior work during business hours without interior impact, or perform sensitive areas during off-hours and weekends when needed.

Question 5

How do weather conditions affect high-rise caulking work?

Accepted Answer

High-rise work requires careful weather monitoring due to increased wind exposure (work suspended above 25-30 mph), temperature requirements for sealant application (typically 40-100°F), and precipitation concerns. We maintain flexible scheduling, use weather-appropriate sealant formulations, and work within manufacturer specifications for optimal adhesion and cure.

Question 6

Do you provide ongoing maintenance programs for high-rise buildings?

Accepted Answer

Yes, we offer comprehensive maintenance programs including annual or biannual envelope inspections, preventive maintenance schedules, priority response for emergency repairs, and detailed reporting on joint condition and remaining service life. These programs identify issues early, extend sealant life, and maintain optimal building envelope performance.

Question 7

What is the typical lifespan of high-rise sealant systems?

Accepted Answer

Premium silicone sealants typically last 20-25 years when properly installed and maintained. Polyurethane sealants average 15-20 years. Actual service life depends on UV exposure, building movement, sealant quality, and maintenance. We provide detailed warranties ranging from 10-20 years based on system type and application.

Question 8

How quickly can you respond to emergency leak repairs?

Accepted Answer

We offer 24/7 emergency response with typical on-site arrival within 4-24 hours depending on location and access requirements. Our emergency team carries temporary and permanent repair materials, access equipment, and can perform immediate water intrusion mitigation followed by permanent sealant repairs.

Question 9

What causes sealant failure in high-rise buildings?

Accepted Answer

Common failure causes include: UV degradation and weathering, excessive joint movement beyond sealant capacity, improper surface preparation during original installation, incompatible materials, building settlement or structural movement, and age-related hardening. We perform forensic analysis to identify root causes and specify appropriate replacement systems.

Question 10

How do you ensure quality control on high-rise projects?

Accepted Answer

Our QC program includes: pre-installation adhesion testing on each substrate type, documented joint preparation verification, sealant batch tracking and cure testing, daily work documentation with photos, independent third-party inspections when specified, and post-completion warranty inspections. Every joint meets ASTM and manufacturer specifications.
