Real 2026 cost ranges for sealants, balcony membranes, parkade coatings, concrete repairs, and leak investigations — from the contractor's own pricing.
Open the guide Resource HubRainscreen Systems: how Vancouver buildings shed rain
How a rainscreen assembly works, how to tell if your building has one, the flashing details that fail, and when a staged remediation is honest versus a full wrap.
Open the guide Resource HubWater Ingress: finding where the rain gets in

Preparing a building before the fall storms, triaging damage after them, temporary repairs that do not trap water, and how to document everything for the strata record.
Open the guide Resource HubCondensation & Damp: when the moisture comes from inside
Telling condensation from a leak, why closet corners go black first, what failed window seals look like, and the ventilation habits that keep Vancouver suites dry in winter.
Open the guidePressure Washing vs Soft Washing Building Exteriors in Metro Vancouver
High-pressure water strips algae off a Coquitlam wall fast — and can blast the coating, sealant, and concrete off with it. When soft washing is the right call, and why surface prep before coating decides everything.
Building Envelope Warranty Claims for BC Strata Corporations
When a New Westminster strata finds an envelope defect, the first question is who pays — the 2-5-10 warranty or the owners. How to tell a warranty defect from maintenance, document it, and meet the deadlines that decide the answer.
Metal Flashing Detail Failures in BC Rainscreen Walls
Good cladding doesn't keep a Burnaby wall dry — flashing does. Reverse laps, missing end dams, and bad transitions are why rainscreen buildings still leak, and why the metal almost nobody looks at deserves the attention.
Cathodic Protection for Chloride-Contaminated Parkades in Vancouver
Road salt drives chloride deep into Surrey and Vancouver parkade slabs, and patch repair alone won't stop the corrosion it starts. When cathodic protection makes sense, how it works, and what it costs you to ignore it.
Swing Stage and Street Use Permits for Downtown Vancouver Facade Work
Before a swing stage touches a downtown Vancouver tower, the City wants a street use permit and a pedestrian protection plan. Here's what that involves, why it delays projects, and how rope access sidesteps most of it.
Concrete Carbonation on Coastal BC Buildings
Not all rebar corrosion is salt. On older Victoria concrete buildings, carbonation quietly lowers the concrete's pH until the steel loses its protection.
Vapour Barrier Failure and Interstitial Condensation in BC Walls
The water staining a Coquitlam condo's interior wall isn't always a leak. Sometimes the wall makes its own water — warm air condensing inside the cavity.
Corroding Balcony Guardrail Anchors on Vancouver Strata Towers
The rust staining at the base of a balcony railing post in Burnaby isn't cosmetic — it's a corroding anchor pushing the concrete apart, and a safety problem.
Field Sealant Adhesion Testing on BC Restoration Projects
A sealant that won't stick is a leak waiting to happen. Why a hand pull test on a Surrey restoration project catches the failure before it ever ships.
Brick Masonry Repointing on Vancouver Heritage and Older Buildings
Use the wrong mortar to repoint a heritage brick building in New Westminster and you'll spall the brick faces within a few winters. Why hardness matters.
Roof Drain and Scupper Maintenance on Vancouver Strata Flat Roofs
A clogged roof drain is the cheapest leak you'll ever ignore — until ponding water destroys the membrane. How Burnaby strata roofs fail at the drains.
Expansion Joint Failure Between Precast Concrete Panels in Vancouver
The joints between precast panels on a Vancouver high-rise move constantly, and sealant is the only thing keeping rain out. Why they fail and how to fix them.

Winter restoration on a West Vancouver building is possible, but coatings, sealants, and concrete have temperature and dew-point limits. How crews manage it.
Building Envelope Engineer vs Contractor: Roles on a BC Strata Project
On a Coquitlam strata restoration, the engineer specifies and the contractor builds. Who does what, who warranties what, and why you need both on a project.

The white salt bloom on a North Vancouver concrete wall is a map of water moving through the structure. What it signals and how to fix the real cause.
When to Recoat a Parkade Traffic Membrane in Vancouver
Deferring a parkade traffic-coating recoat is how a Richmond strata turns a maintenance bill into a slab replacement. How to read wear before it's too late.
Envelope work on a low rise: what changes when the building is three storeys
The physics of a leaking building are the same at three storeys as at thirty. Access, occupancy and sequencing are not. What differs on low rise envelope work.
EPDM vs TPO Flat Roof Membranes for BC Strata Buildings
Choosing between EPDM and TPO single-ply membranes on a Burnaby strata low-rise comes down to seams, reflectivity, and how each ages in Pacific NW rain.
Why Gutter and Scupper Cleaning Belongs in Your Rope Access Maintenance Visit
Blocked gutters, scuppers, and roof drains send water where it was never meant to go — usually into the parapet or down the face of the building. Why this belongs in the same rope access visit as window cleaning and sealant inspection, not a separate call.
Window Perimeter Sealant Failure on Vancouver Curtain Wall Towers
The sealant around window and curtain wall joints is the first line of defence against wind-driven rain on a Vancouver tower — and the first thing to fail. How to spot it, why it happens, and what restoration actually involves.
Sealant Removal vs Cap-Bead Repair: When to Use Each on BC Buildings
Cap-bead sealant repair is faster and cheaper than full removal and replacement — but it's also the most common reason re-caulking work fails within two years. When each approach makes sense, what the actual labour difference is, and how to specify the right approach in your tender.
Engineered Stone and Composite Cladding Panel Failures on Vancouver Towers
Composite panel cladding — engineered stone, fibre cement, aluminum composite — has dominated Vancouver tower facades since 2005. The failure modes are now becoming visible as the first generation reaches 15-20 years in service. What property managers need to know about inspection, repair, and replacement.
Building Envelope Due Diligence for Vancouver Condo Buyers
Before you write an offer on a Metro Vancouver condo, the building envelope is the single biggest source of surprise costs. What to ask, what documents to read, and what red flags to walk away from — written for buyers, not for engineers.
Spray Polyurethane Foam Roofing on BC Commercial Buildings: When It Makes Sense
Spray polyurethane foam (SPF) roofing is well established in colder North American climates but used sparingly in coastal BC. Where it works, where it fails, and how it compares to the membrane systems that dominate Metro Vancouver flat-roof installations.
Vinyl Deck Membrane vs Liquid-Applied Membrane for BC Balconies
When BC strata balconies need new waterproofing, the choice between vinyl deck membrane and liquid-applied polyurethane membrane drives both upfront cost and long-term maintenance. A side-by-side comparison covering lifespan, repair, walking surface, and where each system makes sense.
EIFS vs Traditional Stucco for BC Multifamily Buildings
Exterior Insulation and Finish Systems (EIFS) and traditional three-coat stucco look similar from the street but fail in completely different ways. What BC strata councils and developers need to know before specifying, repairing, or buying a building with either system.
Stucco Crack Repair on Vancouver Low-Rise Buildings Before the Wet Season
Hairline cracks in stucco on a Lower Mainland low-rise turn into wet-season leaks if they're not sealed in late summer. What cracks matter, what to ignore, and how the repair is actually done before October.
Spring and Fall Building Maintenance Checklist for Vancouver Strata Councils (2026)

The Metro Vancouver depreciation report deadline of July 1, 2026 has passed. Here is what that means for stratas without a current report, and which building envelope work drives the 30-year reserve forecast.
Parkade Slab Restoration in Vancouver: What's Eating Your Concrete From Below
Underground parkades fail from a different direction than balconies — de-icing salt, standing water, and chloride driving corrosion through suspended slabs and columns. Here's how Vancouver parkade restoration actually works.
