Sealants and caulking
Effective sealants and caulking are a critical part of keeping water out and protecting your building envelope. Deteriorating window seals, failed joints, and cracked concrete are some of the most common sources of water leaks, rot, and even mold, but also some of the easiest to prevent when addressed early.
WCP Building Renewal provides expert caulking, crack sealing, and leak repair services for high-rise, low-rise, and commercial buildings across Vancouver. Our team can confidently identify problem areas, complete leak detection testing, and restore critical joints and surfaces to prevent water intrusion and long-term damage.
We work on all key transition points, including:
- Window and door perimeters
- Expansion and cold joints
- Concrete cracks and wall interfaces
Using high-performance sealants and proven installation methods, we deliver durable repairs to windows, siding, and key transitions – improving wall protection, supporting concrete sealing, and extending the life of exterior surfaces. Where needed, this work ties into siding repair and broader building envelope restoration.

Here’s where the + comes in.
Many coating systems exist on the market for waterproofing high rises, apartment buildings and warehouses. Typically, these paints are applied to concrete, stucco or brick to seal and protect the surface from water ingress and the damages that may ensue. Commonly referred to as elastomeric coatings, these paints must be applied properly to achieve the desired results. In general, these products are applied to a specific ‘mil’ thickness and in some cases, with specialized equipment, in order to achieve the desired results.
Depending on your building’s construction and exposure, an elastomeric coating system may be appropriate, for others, high-build acrylic paints offer the best waterproofing protection. Either way, our project managers will specify the correct paint system and our skilled technicians will apply the product properly to waterproof your building long term.
When it comes to commercial painting, experience matters. Our painting projects include: multi-unit residential complexes, high-rise towers, apartment buildings, shopping centers, offices, facilities and warehouses.
We even helped paint the world’s largest mural! Interior and exterior, we’ve painted, restored and renewed it all.
Epoxies
Certain projects require highly specialized coatings systems. For buildings and facilities that require long term protection, color retention and ease of maintenance, often epoxy paints are used. For instance, structural steel requires protection from rust and deterioration long term. Metal siding on facilities and factories requires long term protection from UV and weather damage, factory floors require coating systems that can handle high traffic and heavy duty equipment. In these instances epoxy paint and coating systems are often applied. Our project managers work directly with specialty suppliers to specify and source the appropriate epoxy paint system to protect your building or facility, ensuring maximum performance.
Membranes
Exposed deck and balconies on high rises are typically protected with a liquid membrane. Membranes require significant preparation work including washing, paint removal, concrete repairs and levelling, installation of cant strips, priming and application of the membrane.
This work typically requires specific application of the membrane to deck walls and eyebrows to properly protect the entire area. If you are interested in membranes, our project managers will work with you to discuss options and to specify the correct membrane product for your project,
