Professional Sealant Replacement Services
Expert replacement of deteriorated sealants with high-performance materials to prevent water intrusion and protect your building envelope.
Why Sealant Replacement is Critical
Sealants are the first line of defense against water intrusion in building envelopes. Over time, exposure to UV radiation, temperature fluctuations, and weather conditions causes sealants to deteriorate, crack, and lose their adhesion. Failed sealants are one of the most common causes of building envelope leaks.
Our professional sealant replacement services use high-performance materials and proven application techniques to restore the water-tight integrity of your building envelope. We specialize in replacing sealants around windows, doors, joints, and penetrations with materials designed for long-term performance in Vancouver's climate.
High-Performance Sealant Materials
We use only the highest quality sealants designed for building envelope applications.
Polyurethane Sealants
High-performance polyurethane sealants offer superior adhesion, flexibility, and durability for demanding applications.
- Excellent adhesion to most building materials
- Superior flexibility and movement capability
- UV resistant and weatherproof
- Long-term durability (15-20 years)
- Paintable when cured
Silicone Sealants
Premium silicone sealants provide excellent weather resistance and flexibility for specific applications.
- Outstanding weather and UV resistance
- Maintains flexibility in extreme temperatures
- Excellent for glass and metal applications
- Mold and mildew resistant
- Long service life with minimal maintenance

Properly sealed joints prevent water intrusion that can cause structural damage and mold growth.
Energy Efficiency
Proper sealing reduces air leakage, improving building energy efficiency and comfort.
Cost-Effective Maintenance
Regular sealant replacement is much more cost-effective than major envelope repairs.
Professional Installation
Expert installation ensures optimal performance and longevity of sealant materials.
Warranty Protection
Our professional installation comes with warranty coverage for materials and workmanship.
Signs Your Sealants Need Replacement
Recognize these warning signs that indicate sealant replacement is needed.
Cracking
Visible cracks in the sealant that allow water penetration.
Adhesion Loss
Sealant pulling away from surfaces, creating gaps.
Hardening
Sealant becomes hard and brittle, losing flexibility.
Discoloration
UV damage causing sealant to change color or appearance.
Water Stains
Evidence of water intrusion around sealed joints.
Age
Sealants over 10-15 years old should be evaluated for replacement.
