Calgary Building Envelope Remediation
Weststar Wall Systems provides professional building envelope assessment, repair and remediation services in Calgary for residential, commercial and multi-family buildings.
Building envelope failures can occur when exterior wall systems, waterproofing membranes, flashings, windows, doors, EIFS or stucco systems allow water or air to enter the wall assembly. Over time, these issues can lead to hidden moisture damage, deteriorated sheathing, damaged framing and failure of exterior finishes.
Our building envelope services include:
-
Building envelope remediation and restoration
-
Water intrusion and moisture-related repairs
-
Exterior wall system removal and replacement
-
Damaged sheathing and framing repairs
-
Weather barrier and waterproof membrane installation
-
Window and door interface repairs

Flashing repairs and replacement
-
EIFS and stucco remediation

Rainscreen and exterior wall improvements
-
Exterior restoration and refinishing
Our approach goes beyond repairing visible damage. Weststar works to identify the source of the building envelope failure, assess affected components and develop an appropriate remediation strategy designed to restore water management, weather protection and long-term durability.
From localized water intrusion repairs to complete exterior wall remediation, Weststar provides building envelope restoration solutions throughout Calgary and surrounding areas.

Commerical Restoration
Weststar works with general contractors, property managers, condominium corporations, building owners and commercial clients on exterior restoration and remediation projects.
​​l
We understand that restoration projects require more than a quality exterior finish. Proper sequencing, moisture management, flashing, membranes, substrate preparation and manufacturer requirements are critical to the long-term performance of the building envelope.

EIFS Systems
EIFS is one of Weststar's core specialties.
Our team provides complete EIFS installation, restoration and remediation, including removal of failed systems, substrate and sheathing repairs, weather-barrier installation, insulation, base coat, reinforcing mesh and new acrylic finishes.
We work with leading EIFS systems and follow manufacturer specifications and proper building-envelope detailing.
​

Stucco Systems
​
Weststar provides professional stucco restoration for residential, commercial and multi-family buildings.
Whether the problem involves cracking, water intrusion, failed flashing, damaged substrate or deterioration of an existing stucco system, we can assess the existing conditions and develop an appropriate restoration approach.

Shieldit - Woodpecker
Woodpecker damage is a common problem on EIFS buildings throughout Calgary and Alberta.
Weststar provides professional repair of woodpecker-damaged EIFS and offers ShieldIt protective coating systems designed to help prevent recurring woodpecker damage.
Our process can include repairing existing penetrations, restoring damaged EIFS and applying protective treatment to vulnerable areas or complete elevations.
