EIFS Installation, Repair & Remediation
Weststar Wall Systems provides professional EIFS installation, repair, restoration and remediation services in Calgary for commercial, residential and multi-family buildings.
With extensive experience working with Exterior Insulation and Finish Systems (EIFS), our team can assess existing wall conditions, identify areas of deterioration or water intrusion, and develop repair or replacement solutions appropriate for the building and existing exterior wall assembly.
Our EIFS services include new EIFS installation, EIFS repairs, water-damage remediation, removal and replacement of failed systems, sheathing and substrate repairs, weather-barrier integration, flashing repairs, window and door interface detailing, impact-damage repairs and exterior refinishing.
Whether the project involves a localized EIFS repair or extensive exterior wall remediation, Weststar focuses on proper system integration, moisture management, durability and a finished appearance that complements the existing building.
Serving Calgary and surrounding Alberta communities.
What is EIFS?
EIFS is a multilayered cladding system that provides exterior walls with an insulated, water and fire resistant finished surface. It has the aesthetic appeal that you are looking for from a stucco finish but with substantial functional improvements.
Why EIFS?
Energy Efficient\\ Reduces air infiltration by as much as 55%. Your walls are the greatest areas of heat and air conditioning loss so any improvements to wall insulation becomes very meaningful in terms of energy conservation.
Durability\\ Designed to be very flexible which allows it to absorb "building movement" over time. This makes the system highly crack resistant and because its formulated with 100% acrylic binder, it rarely needs painting.
​
Design Flexibility\\ With the limitless colours and textures, it's versatile in that it can bear a resemblance to stucco or stone but also be fashioned into virtually any shape or design.
Water Resistance\\ Water channels between the insulation and your building substrate prevent moisture buildup in the exterior. Water intrusion is rare because this system is fastened using an adhesive which is non invasive to your wall structure (no nails).
Fire Resistance\\ The system has passed the major fire resistance tests that is required by building code in terms of ignitability and flame spread.

Benefits of EIFS Systems for Calgary’s Climate
Calgary's climate presents unique challenges for exterior wall systems, including cold winters, rapid temperature changes, freeze-thaw cycles, strong winds and seasonal moisture exposure. A properly designed and installed Exterior Insulation and Finish System (EIFS) can provide an effective exterior wall solution for these demanding conditions.
Continuous Exterior Insulation
EIFS places insulation on the exterior side of the wall assembly, creating a more continuous thermal layer. This helps reduce thermal bridging through framing and other building components and can improve the overall thermal performance of the exterior wall.
Improved Energy Efficiency
By adding continuous exterior insulation and reducing unwanted heat transfer, EIFS can contribute to improved building energy efficiency, indoor comfort and temperature stability—particularly valuable during Calgary's cold winter months.
Performance During Calgary Temperature Changes
Calgary can experience significant temperature fluctuations over short periods. A properly installed EIFS assembly helps protect underlying wall components while providing continuous insulation between the conditioned interior and changing exterior temperatures.
Moisture Management
Modern EIFS assemblies can incorporate weather barriers, drainage provisions, flashings and properly detailed window and door interfaces to help manage incidental moisture and direct water away from vulnerable components of the building envelope.
Lightweight & Versatile Exterior Finish
EIFS provides insulation and architectural finishing without the weight associated with many traditional masonry cladding systems. It can accommodate a wide variety of textures, colours, profiles and architectural details, making it suitable for both new construction and exterior building restoration.
Ideal for Building Envelope Upgrades
For existing Calgary buildings undergoing exterior restoration, EIFS can provide an opportunity to upgrade exterior insulation while repairing deteriorated sheathing, membranes, flashings and other building-envelope components.
When properly designed, detailed and installed, EIFS can provide Calgary buildings with a combination of continuous insulation, energy efficiency, moisture management, architectural flexibility and long-term exterior performance.
