You may need new caulking when you see cracking, shrinking, peeling, or gaps forming around windows, doors, siding joints, expansion joints, or facade penetrations. Drafts, water stains inside the home, increased humidity, or higher-than-normal utility bills are also signs that your seals are failing. Over time, sealants lose elasticity and adhesion due to UV exposure and weather. A professional evaluation can determine whether targeted resealing is enough or if a full replacement is required for proper protection.

A properly installed EIFS system can last between 30–50 years or longer when maintained correctly. Longevity depends on routine inspections, timely caulking replacement, prompt repairs of cracks or impact damage, and maintaining proper drainage. Because EIFS is both an insulation and façade system, keeping its protective layers intact is crucial for moisture management, energy performance, and structural health. With preventive maintenance, an EIFS façade can outperform many traditional exterior finishes.

Exterior waterproofing systems and sealants should be inspected every 2–3 years, but high-exposure properties, such as those with heavy sun, wind, or freeze-thaw cycles, may require annual assessments. Severe storms, building movement, aging materials, and UV radiation all accelerate wear. Inspections help detect small failures before they become leaks or structural issues. Keeping up with regular evaluations ensures long-term protection, lowers repair costs, and preserves the integrity of the building envelope.

Moisture intrusion can occur for several reasons, including failed caulking, worn-out sealants, cracks in masonry, improper EIFS installation, missing flashing, clogged weep systems, or deteriorated waterproofing membranes. When these protective layers break down, water can enter the wall assembly and lead to mold, rot, freeze-thaw damage, and structural weakening. Regular inspections and prompt repairs are essential to keeping the building envelope watertight and preventing long-term damage.

Repointing is the process of removing deteriorated or loose mortar and replacing it with new mortar to restore structural stability and prevent moisture penetration. Tuckpointing includes the same steps but adds a more detailed finishing technique that uses a contrasting thin mortar line to create the appearance of crisp, clean joints. Repointing focuses on durability and protection, while tuckpointing enhances the aesthetic of brickwork, especially on historic or decorative façades. Both significantly extend the life of masonry systems
