A Leak Doesn't Always Mean System Failure
Water showing up inside near a curtain wall or window wall system understandably worries building owners — recladding an entire elevation is a serious cost. In our experience, most leaks trace back to a specific, fixable failure point: a degraded gasket, a cracked sealant joint, or a blocked weep system, not the whole assembly.
Why Getting the Diagnosis Right Matters
Recommending a full recladding when a modest sealant repair would have solved the problem wastes your capital budget. On the other hand, patching a symptom while ignoring a structural sealant failure means the leak comes back. We investigate properly, including water testing where it's warranted, before recommending a scope.
Repair Options: Gaskets, Sealant, and Weep Systems
Failed perimeter gaskets and degraded sealant joints are the most common leak sources we find, both repairable without disturbing the glass. Blocked weep holes — the small drainage paths built into the system — can trap water inside the wall assembly if they're clogged with debris. We clear, reseal, or replace these components as the specific failure requires.
Glass and Panel Replacement at Height
Broken or fogged curtain wall units, spandrel panels, and operable vents can usually be replaced individually without disturbing adjacent sections. Depending on the building and access, we use swing stage, boom lift, or interior glazing methods, always under a documented fall protection plan that meets Ontario working-at-heights requirements.
Not a DIY or General-Handyman Job
Curtain wall systems are engineered assemblies — pressure plates, gaskets, and sealant joints all work together to manage water and air. A repair done without understanding that system usually just relocates the leak. This is specialized glazing work, and it should be treated that way when you're choosing a contractor.
New Installation for Renovations and New Construction
For new construction and major renovations, we install stick-built curtain wall and pre-glazed window wall systems on projects up to mid-rise scale, sequenced with your general contractor's schedule and coordinated with other envelope trades so nothing holds up the project.
What to Expect for Cost and Access
Repair costs vary widely depending on cause and access — a ground-accessible gasket repair might run a few hundred dollars, while swing-stage panel replacement on a mid-rise elevation is priced per project once we've assessed access and scope. We'll always separate investigation cost from repair cost in the quote.
If You're Seeing Water or Fogging
Contact us for a leak investigation before anyone talks about recladding. We'll identify the actual water path, show you what we find, and quote the repair that actually fixes it.
Issues We Hear About Most Often
Property managers, retailers, and GCs across the GTA run into the same patterns. Here is what usually brings people to this service — and how we approach it.
Recladding sounds like the only option
Most leaks trace to a gasket, sealant joint, or blocked weep, not the whole system. We investigate before recommending anything close to full recladding.
Elevated access makes owners nervous about cost
Swing stage or boom lift work sounds expensive before you know the actual scope. We separate the investigation from the repair quote so you're not committing to a number before we know what's wrong.
Confusion over glazing vs. hollow metal scope
On mixed storefront and curtain wall jobs, it's not always clear where glazing scope ends and hollow metal work begins. We handle both, so scope gaps don't fall through the cracks.
A leak that keeps coming back
Patch jobs that address a symptom instead of the failure point tend to leak again within a season. We trace the actual water path first.
