Flexible, long-lasting solutions for structural movement control
Expansion joints are critical to preserving the integrity of buildings, especially large structures subject to natural movement from thermal shifts, seismic activity, or settling. AFR delivers expertly designed and installed expansion joint systems that allow your building to breathe—without compromising performance or aesthetics.
We work with high-quality materials engineered for durability, flexibility, and resistance to water, air, and debris intrusion. Whether it’s for vertical or horizontal joints, interior or exterior applications, our team ensures every installation meets project specifications and performs reliably for the long haul.
Benefits of our expansion joint services:
Absorb movement without causing damage or cracks
Protect against water and air infiltration
Maintain building performance in all seasons
Seamlessly integrate with building finishes and design
At AFR, we know movement is inevitable—but damage doesn’t have to be. Our expansion joint solutions safeguard your structure and your investment with professional precision and lasting protection.

When Structures Shift, Expansion Joints Protect What Matters
Buildings move. Whether it’s temperature fluctuations, seismic activity, or material settling over time, expansion and contraction are inevitable. Without properly installed and maintained expansion joint systems, that movement can lead to serious consequences—cracked facades, water intrusion, structural stress, or even safety hazards.
At AFR Windows, we design, install, and repair expansion joint systems that protect your building envelope while blending seamlessly into your architecture. From commercial high-rises to multifamily complexes, we provide solutions that perform—quietly, reliably, and code-compliantly.
The Problem: Movement Without Flexibility Causes Failures
The San Francisco Bay Area is no stranger to environmental stresses. Earthquakes, coastal weather, and urban development mean that most structures experience constant subtle shifts. But many buildings are still operating with aging, brittle, or undersized expansion joints that no longer meet performance demands.
We often see issues like:
Water intrusion at failed expansion joints
Deteriorated or missing joint covers
Joint materials that can’t withstand seismic or thermal stress
Air leaks affecting building efficiency
Visible gaps or misaligned cladding
Expansion joints are often overlooked—until they fail. That’s why it’s critical to have a system designed for your specific building type, location, and usage.
The Solution: Seamless, Long-Lasting Expansion Joint Systems
AFR Windows offers complete expansion joint solutions, whether you’re upgrading a single elevation or managing a full building envelope restoration. Our systems are engineered to accommodate multidirectional movement while maintaining weatherproofing and visual cohesion.
Our expansion joint services include:
Design and specification for new or retrofit projects
Waterproof expansion joint systems for walls, roofs, and below-grade locations
Seismic-rated joints for hospitals, high-rises, and code-sensitive structures
Fire-rated joint systems for life safety compliance
Architecturally integrated covers in metal, elastomeric, or concealed finishes
Inspection, maintenance, and replacement of aging joints
Every solution is tailored to your building’s needs—whether it’s a mission-critical facility, a downtown condo tower, or a tech campus with pedestrian pathways.
Protecting Buildings Across the Bay Area
From San Francisco’s seismic retrofit projects to expansion joint repairs on office parks in Walnut Creek, AFR Windows is trusted by:
General contractors seeking expert envelope subcontractors
Architects and engineers needing movement-compatible detailing
Property managers responsible for long-term building performance
Facility directors who can’t afford envelope failures in occupied spaces
We work on everything from podium deck joints to vertical plane transitions, always delivering systems built to last and backed by warranty.
Installation That Holds Up to Real-World Conditions
An expansion joint is only as good as its installation. Our certified field teams are trained in both manufacturer protocols and local code requirements to ensure:
Full adhesion and weather seal performance
Proper anchoring and substrate preparation
Seamless transitions between systems (e.g., curtain wall to slab edge)
Field testing for water tightness when required
Coordination with other envelope components like waterproofing, cladding, or curtain wall systems
You can’t afford a weak link in your building envelope—especially not at the joints.
Extend the Life of Your Building With the Right Expansion System
Modern expansion joint materials and designs offer superior performance, including:
Resistance to UV, moisture, and temperature extremes Sound attenuation and vibration dampening Minimal visual disruption with customizable cover options Compatibility with waterproofing and firestopping Long-term movement capacity without fatigue
Whether you’re planning new construction or dealing with leaks in a 30-year-old property, the right joint system can dramatically improve envelope integrity.
