Exposed Slabs Take a Beating
Balconies and terraces sit through rain, snow, salt, ultraviolet exposure, freeze-thaw cycles, furniture, planters, and foot traffic. Once the coating or membrane fails, water finds cracks, railing penetrations, drains, thresholds, and slab edges quickly.
Condo and Multi-Unit Priorities
Balcony work affects residents directly. We coordinate access, notices, swing stage or lift requirements, furniture movement, dust, noise, and cure times. For boards and property managers, we provide phased options and documentation that helps owners understand why the work cannot be treated as paint.
Membranes, Coatings, and Details
Depending on the assembly, we install liquid-applied membranes, trafficable coatings, sheet membranes, flashing, drain detailing, crack repair, and sealant transitions. We pay close attention to thresholds, scuppers, drains, railing posts, and perimeter edges because that is where many failures start.
Concrete Repair Comes First
Waterproofing over cracked, delaminated, or contaminated concrete is a short-term patch. We sound the slab, repair spalls and cracks, prepare the surface, and then install the waterproofing system over a substrate that can hold it.
Costs and Scope
Balcony and terrace costs vary by access, coating system, concrete repair, railing details, and whether finishes must be removed. Localized coating repairs may be modest; full terrace membrane replacement is a capital project. We quote the repair areas, prep, membrane, and restoration separately.
Drainage and Ponding
A membrane can resist water, but it should not be forced to hold standing water indefinitely. We check drains, slopes, scuppers, and blocked outlets so the system can shed water as designed.
Clean, Resident-Friendly Work
We protect unit interiors during access, keep debris controlled, and communicate cure times clearly. A clean-site guarantee matters most when the work is happening outside someone's home or active amenity space.
Issues We Hear About Most Often
Boards, property managers, and GCs across the GTA run into the same leak patterns. Here is what usually leads to this service — and how we approach the repair.
Leaks show up in the unit below
Water may travel from a drain, railing post, threshold, or crack before appearing below. We trace likely paths instead of patching only the stain.
Owners think it is just paint
Traffic coatings and membranes are waterproofing assemblies. We explain prep, cure, and detailing so boards can set expectations.
Concrete is already delaminating
Loose concrete must be repaired before waterproofing. Coating over weak substrate leads to early failure.
Access disrupts residents
Balcony work requires notices, furniture movement, and cure times. We phase and communicate access requirements clearly.
