Precise applications ensuring durability and leak prevention
When old or failing sealants break down, buildings become vulnerable to water infiltration, energy loss, and structural damage. At AFR, we specialize in the expert removal of deteriorated sealants and the precise installation of high-performance sealant systems tailored to each building’s materials and movement characteristics.
Our experienced team ensures clean removals and applies industry-leading sealants that provide long-lasting adhesion, flexibility, and weather resistance. Whether it’s a high-rise commercial facade or a historic residential property, we understand the critical role sealants play in waterproofing and maintaining your building’s integrity.

The Smallest Gaps Can Lead to the Biggest Problems
Sealants are your building’s first line of defense against water, air, and energy loss. But over time, UV exposure, temperature shifts, and building movement can cause sealants to dry, crack, or detach—especially in the Bay Area’s mix of fog, salt air, and seismic activity.
At AFR Windows, we specialize in professional sealant removal and installation services that protect your property from leaks, mold, and costly damage—without compromising the building’s appearance or performance.
The Problem: Aging or Improper Sealants Compromise Building Integrity
We often find that buildings constructed or last updated decades ago are now showing signs of sealant failure:
Visible cracking or shrinkage around joints and window perimeters
Water stains inside units or along exterior walls
Drafts and energy inefficiencies
Mold or mildew in ceilings and wall cavities
Even worse, many properties suffer from improper sealant application during past work—leading to premature failure or incompatibility with surrounding materials.
The Solution: Expert Sealant Systems That Seal, Flex, and Last
AFR Windows provides full-service sealant removal and reinstallation on commercial buildings, multifamily properties, and high-rises throughout the Bay Area.
Our process includes:
Thorough inspection of existing joints, substrates, and past work
Safe removal of failed sealant using specialized equipment
Substrate preparation and cleaning to ensure adhesion
Application of high-performance, building code-compliant sealants
Use of color-matched products for a seamless look
Final inspection to verify airtight, watertight seals
We use elastomeric, polyurethane, and silicone sealants—each selected based on building material, expansion movement, and exposure conditions.
Who We Serve
Our sealant work is trusted by:
HOAs and property managers maintaining aging multifamily exteriors
General contractors and architects needing long-lasting envelope protection
Commercial building owners facing facade leaks or code issues
Developers preparing buildings for final occupancy inspections
From expansion joints to curtain wall perimeters, our crews can scale up or down depending on your project size and timeline.
What Areas Typically Need Sealant Replacement?
Over time, sealants degrade in areas such as:
Window and door perimeters
Curtain wall transitions
Precast and concrete panel joints
Brick and masonry control joints
Stucco and EIFS termination points
Balcony-to-wall interfaces
Roof-to-wall or parapet joints
If your building is 15+ years old and has never had a sealant refresh—or if you’re seeing signs of water intrusion—it’s time to evaluate.
Sealant Installation Done Right, Every Time
Our sealant crews are:
✅ Manufacturer-certified and trained in multi-surface applications
✅ Equipped to work on occupied buildings with minimal disruption
✅ Experts in substrate compatibility and joint design
✅ Compliant with all OSHA, EPA, and city-specific guidelines
✅ Backed by warranty programs and documentation support
We don’t cut corners. We build seals that protect against weather, water, and warranty risk.
