When and Why to Replace Joint Sealants: A Proactive Approach to Building Maintenance 

Maintaining the integrity of your building’s envelope starts with the details—and joint sealants are one of the most overlooked components. These flexible materials (often referred to as caulking) seal the joints, windows, doors, and transitions between different materials. But over time, sealants can degrade, crack, or lose adhesion—leading to water intrusion, energy inefficiencies, and even long-term structural damage.

With spring here, now is the ideal time to inspect your property’s sealants. Shifting temperatures and increased moisture can expose weaknesses in aging caulking. Proactive replacement before summer storms or humidity sets in can help you avoid costly repairs down the line.

What Are Joint Sealants and Why Do They Matter?

Joint sealants are applied to close gaps between materials—especially around windows, doors, vents, and expansion joints. These materials are designed to move with the building as it expands and contracts due to weather, moisture, and structural shifts.

However, like all building materials, joint sealants have a lifespan. Exposure to UV rays, freeze-thaw cycles, material movement, and high humidity can all cause them to break down. Once that happens, the building becomes vulnerable to:

  • Water Infiltration: Gaps in deteriorated sealant can allow rainwater to enter, causing moisture damage, mold, or rot.

  • Energy Loss: Air leaks around windows and doors reduce a building’s energy efficiency, increasing HVAC costs.

  • Structural Damage: Over time, water intrusion can deteriorate materials behind the façade, threatening the structure’s stability.

Signs It’s Time to Replace Sealants

Not sure if your building needs a caulking refresh? Watch for these indicators:

  • Cracks, gaps, or peeling sealant

  • Water leaks around windows or walls after rainfall

  • Drafts or temperature inconsistencies near openings

  • Mold or mildew at joints and transition areas

  • Aging sealant—most products have a service life between 5 and 15 years

BEG’s Proactive Approach

At BEG, we understand how critical it is to maintain a watertight envelope. Our approach to joint sealant replacement focuses on long-term performance, not just quick fixes.

  • Lifecycle360 Integration: Our LifeCycle360 program tracks the condition of building envelope components over time. This allows us to recommend repairs based on real-time data and prioritize maintenance before problems escalate.

  • Material Selection Expertise: From silicone to polyurethane, we use the right product for the environment and substrate to ensure lasting performance.

  • Precision Installation: Our field teams follow manufacturer-approved procedures to ensure proper adhesion and joint movement, avoiding premature failures.

  • Long-Term Value: Replacing joint sealants now prevents larger issues later—helping preserve your building’s appearance, efficiency, and structural soundness.

Don’t Delay Critical Maintenance

Neglecting sealants can have a ripple effect, compounding deferred maintenance costs over time. It’s a small, strategic investment that protects your building from major—and often preventable—damage.
