Keeping Your Building Looking Great: The Importance of Regular EIFS Inspections and Repair

Unlocking the Secrets of EIFS Durability: Your Ultimate Guide to Inspection and Repair

As a homeowner or building owner, you want your property to look its best and maintain its value. For buildings with exterior insulation and finish systems (EIFS), also known as synthetic stucco, regular inspections and proper maintenance are crucial. Read on to learn why EIFS inspections and repairs should be a key part of your building maintenance plan.

What is EIFS?

EIFS refers to a type of exterior wall cladding that consists of several layers applied over the substrate, or exterior wall. It is sometimes confused with traditional stucco, but EIFS is a very different wall system. The main components of an EIFS wall include:

  • Substrate – Typically made of plywood, OSB, brick, concrete block, poured concrete, or CMU. This provides the structural base that the EIFS is attached to.
  • Adhesive – Used to bond the insulation boards to the substrate.
  • Insulation boards – Rigid expanded polystyrene (EPS) foam boards that provide thermal insulation and impact resistance.
  • Base coat – A fiber-reinforced polymer and cement layer that embeds the reinforcing mesh.
  • Reinforcing mesh – Glass fiber mesh embedded in the base coat to provide strength and impact protection.
  • Primer coat – Optional layer to improve finish coat bond.
  • Finish coat – Acrylic-based coating available in various textures and colors. This is the decorative exterior layer.

The multiple layers of EIFS provide excellent insulation, improving the building’s energy efficiency and reducing heating and cooling costs. EIFS is also lightweight yet durable, can be customized with various textures and colors for aesthetically pleasing designs, and protects against moisture intrusion when properly installed and maintained.

The Benefits of Using EIFS

The Benefits of using EIFS

There are several reasons EIFS has become such a popular choice for residential and commercial buildings:

  • Outstanding thermal performance – EIFS can reduce heat loss through walls by up to 85% compared to brick or siding. This significantly lowers heating and cooling energy usage.
  • Aesthetic versatility – EIFS can be crafted into nearly any shape and texture. Decorative accents, arches, and custom designs are easily achieved.
  • Speed of installation – EIFS installs faster than other claddings, speeding up construction.
  • Lower maintenance – Properly installed EIFS requires very little ongoing maintenance. It does not need repainting like wood siding.
  • Cost savings – The high insulation value means smaller HVAC systems can be used, resulting in lower construction and operating costs.
  • Weather resistance – EIFS withstands weather extremes, resists rot and decay, and prevents moisture intrusion when properly maintained.
  • Lightweight – Weighing only about 2 to 7 lbs per square foot, EIFS places less load on structures than other claddings.
  • Sustainable – EIFS can qualify for LEED and other green building standards due to its energy efficiency and other eco-friendly attributes.
  • Noise reduction – EIFS provides excellent sound dampening, making it ideal for multi-family housing.

With this outstanding combination of benefits, it’s easy to see why EIFS has surged in popularity over the past 20 years.

The Importance of Proper Installation

To gain all the benefits of EIFS and avoid potential problems, proper installation is crucial. Here are some best practices for installation:

  • Select an experienced EIFS contractor who follows manufacturer guidelines and holds current EIMA certification. Never let an unqualified contractor install EIFS.
  • Use quality materials from reputable brands that are designed to work together as a system. Mixing products can cause failures.
  • Inspect the substrate and make any needed repairs before installing EIFS. The substrate must be in good condition to support the cladding.
  • Include an effective weather-resistant barrier to prevent water intrusion into the wall. A synthetic underlayment or building wrap works well.
  • Attach insulation boards securely to the substrate using manufacturer-approved adhesive. Proper board attachment is critical.
  • Avoid installing EIFS below grade or where it may stay wet. Use an alternate cladding for damp areas.
  • Install code-approved backwrapping and flashings at all openings, penetrations, and transitions to prevent water entry.
  • Embed reinforcing mesh completely in the base coat to provide impact protection and strength.
  • Apply the finish coat to the recommended thickness and texture using a skilled applicator.
  • Seal all joints and edges thoroughly with compatible sealant to prevent water intrusion.

When installed correctly following EIFS best practices, the system will provide many years of optimum performance.

Why are EIFS Inspections So Important?

While EIFS offers numerous benefits, it also requires proper care and maintenance. Moisture issues are the main cause of problems with EIFS buildings. Water intrusion usually enters through imperfections in the EIFS, including cracks, unfinished edges, unfinished penetrations like vents or utilities, and deteriorated or improperly installed flashings around windows, doors, and other openings.

Over time, this moisture intrusion can lead to damage like mold growth, rotting framing, and interior water leaks. That’s why regular professional EIFS inspections are so critical. A thorough inspection can identify issues early so repairs can be made before costly damage occurs.

What Do EIFS Inspections Check For?

A comprehensive EIFS inspection examines all components of the cladding system for proper installation, deterioration, and moisture intrusion risks. Areas of focus include:

  • Attachment of insulation board to exterior wall substrate. Loose boards can allow water intrusion and must be re-secured.
  • Base coat coverage and condition. Bare spots expose the insulation to damage. Cracks in the base coat can admit water.
  • Overall condition of the acrylic finish coat. Cracks, punctures, and deterioration must be repaired to maintain weatherproofing and aesthetics.
  • Sealants around openings and penetrations. Failed or missing sealant is a major source of water entry.
  • Flashings around windows, doors, vents, lights, and other penetrations. Defective flashings cause most EIFS failures.
  • Signs of cracks, punctures, unfinished edges. Any breaches in the EIFS compromise its moisture protection.
  • Water stains or damage. Evidence of moisture intrusion demands further investigation and repair.

Inspectors use methods like visual examination, moisture meters, and infrared cameras to detect potential defects both on the surface and within the wall assembly.

When Should EIFS Inspections Happen?

To maintain peak EIFS performance, inspections should occur at the following key times:

  • After installation – New EIFS should be inspected to verify proper installation before the warranty period begins.
  • Annually – Regular yearly exams allow early identification and repair of small issues before they become major problems. Annual inspections are recommended.
  • After major storms – Strong winds, hail, and blowing debris can damage EIFS. Prompt inspections after severe weather identify any repairs needed to prevent water entry.
  • When problems appear – Signs like cracks, staining, mold, and peeling finish require an immediate inspection to determine the cause and needed repairs.
  • During restoration planning – Inspections help determine whether sections of EIFS can be repaired or need full replacement during restoration projects.
  • Before buying/selling – Inspections provide crucial information on the condition of the EIFS and any needed repairs during real estate transactions.

By making inspections at these key intervals, building owners and managers can stay ahead of EIFS issues and avoid costly damage.

What Repairs May Be Needed?

Based on inspection findings, a range of EIFS repairs may be required:

  • Resealing – Deteriorated sealant around openings, joints, and unfinished edges is replaced to prevent water intrusion. Matching the original sealant type is vital.
  • Reflashing – Defective flashings around windows, doors, lights, and other penetrations are re-installed following EIFS flashing best practices.
  • Patching – Small cracks, punctures, or other finish coat damage can often be repaired by patching and spot priming/repainting.
  • Finish coat renewal – Faded, eroded, or discolored finish coats may need renewal to restore appearance. This involves cleaning, spot repairs, priming, and recoating.
  • Insulation replacement – Moisture-damaged insulation boards must be removed and replaced. New adhesive, base coat, mesh, and finish are applied.
  • Section replacement – In some cases, moisture and system failures require removing large sections of EIFS and replacing all components before recoating.
  • Drainage improvements – Poor drainage is a common deficiency. Improving site drainage, landscaping, and adding moisture management features helps reduce EIFS water exposure.
  • Sensor installation – Moisture sensors that detect leaks as they occur can be installed within the wall assembly during major repairs.

The specific repairs needed depend on the inspection findings and the severity of any damage discovered. In some cases, repairs may be extensive enough that full EIFS replacement is the best option.

Typical EIFS Repair Process

Typical steps for repairing damaged sections of EIFS include:

  1. Damaged areas are marked and isolated. A perimeter is cut around the repair area just through the finish coat and base coat.
  2. Finish coat is carefully removed using scrapers, putty knives or other tools, avoiding damage to the underlying base coat.
  3. Base coat is exposed and any damaged areas are patched. Reinforcing mesh is added if needed.
  4. Insulation boards are removed and replaced if moisture is damaged. New adhesive is applied.
  5. New base coat with embedded reinforcing mesh is applied over insulation boards.
  6. After the base coat cures, a fresh finish coat is applied and textured to blend with surrounding areas.
  7. Paintable caulk is used to seal the repaired perimeter edge.
  8. The repaired area and sealants are painted with matching elastomeric coating to blend with surrounding EIFS.

Proper staging, safety protocols, and handling of hazardous materials are also part of professional EIFS repair. Training and experience are needed to complete repairs correctly.
