Can EIFS (Exterior Insulation and Finish System) Be Repaired?
EIFS (Exterior Insulation and Finish System) can be repaired, but the type of repair depends on the damage.
- Small cracks and holes can be patched with special sealants or coatings.
- Bigger problems, like water damage or peeling layers, may need removing and replacing sections of the system.
- Serious issues, like deep moisture damage or weak spots, require a larger repair or complete replacement.
Repairs range from simple surface fixes to more extensive replacements when moisture infiltration or structural issues are present.
Different Ways We Repair EIFS
The way we repair EIFS depends on the severity of the damage.
EIFS helps insulate buildings and protect them from weather. However, it can be damaged by cracks, holes, water leaks, or weak spots. If the damage is not fixed, it can cause bigger problems.
For Small Cracks, We Fill and Seal the Surface
Small cracks can happen in EIFS because of weather changes, movement in the building, or aging. Even tiny cracks let water in, which can cause more damage. To fix small cracks, we:
✔ Clean the crack to remove dirt so the repair sticks well.
✔ Fill the crack with a special sealant that keeps water out.
✔ Apply a matching finish coat to make sure the repair blends in.
Fix small cracks quickly to stop them from getting bigger and strengthens the EIFS.
For Holes and Dents, We Cut and Patch the Area
Holes in EIFS can happen if something heavy hits it, like hail, a tree branch, or even a ball. Holes weaken the wall and can let water get inside. To repair holes, we:
✔ Cut out the damaged part to remove weak material.
✔ Put in a new insulation board to replace the missing section.
✔ Apply a base coat and fiberglass mesh to make the area stronger.
✔ Add a finish coat that matches the rest of the wall.
This repair ensures the hole is completely sealed and looks like it was never there.
For Water Damage, We Remove and Replace Affected Areas
Water falling behind EIFS can cause mold, rot, and weak spots. Water damage often happens because of cracks, unsealed edges, or poor installation. To fix water damage, we:
✔ Use tools to find where the water got in and how far it spread.
✔ Remove all the wet and damaged EIFS layers so the problem does not spread.
✔ Let the area dry completely before making any repairs.
✔ Replace any wall parts with mold or rot so the structure stays strong.
✔ Install a moisture barrier and seal all openings to keep water out.
✔ Apply new EIFS layers to restore the insulation and protection.
Repair water damage early to prevent severe wall damage and keep the building safe.
For Loose or Peeling EIFS, We Reattach or Replace the Section
Sometimes EIFS starts to peel away from the building because it was not installed properly, water got behind it, or the materials are getting old. This can lead to gaps, weak spots, and insulation problems. To fix loose EIFS, we:
✔ Remove all loose and peeling sections to check the wall underneath.
✔ Inspect the wall to see if there is damage and fix any weak spots.
✔ Attach new insulation boards properly using strong adhesives or fasteners.
✔ Apply a new base coat, mesh, and finish coat to seal and protect the repair.
Reattach loose EIFS to help it stay in place and keep the wall strong and weatherproof.
For Severe Damage, We Replace the Entire EIFS System
If EIFS has severe damage across a large area, minor repairs may not be enough. This happens when the system is very old, has a lot of water damage, or was installed incorrectly. In this case, we replace the entire EIFS system. We do this by:
✔ Removing all old EIFS layers down to the main structure of the building.
✔ Check and repair the wall underneath to ensure it is strong and dry.
✔ Adding a drainage system if needed to prevent future water problems.
✔ Installing new EIFS layers including insulation, a strong base coat, and a weather-resistant finish.
A complete replacement gives the building better insulation, stronger protection, and a fresh appearance.
When to Consider EIFS Replacement
Some problems cannot be fixed with simple repairs. Below are clear signs that a complete EIFS replacement is the best option.
Consider a Replacement if Your EIFS Have Extensive Water Damage
Water trapped behind EIFS weakens insulation, promotes mold growth, and leads to structural decay. Moisture may enter through cracks, poorly sealed joints, or a failed drainage system. If large areas of the EIFS are damp, discolored, or crumbling, a complete replacement is necessary to prevent further damage.
Replace Your EIFS if You Need Frequent Repairs
EIFS should provide long-term protection. If cracks, leaks, or peeling finishes appear repeatedly, the system has likely reached the end of its lifespan. Constant patching does not restore full protection. A complete replacement stops the cycle of repairs and ensures lasting durability.
Choose a Full Replacement if Your EIFS Have Pulled Away from the Wall
EIFS must stay securely attached to provide insulation and weather resistance. Loose or peeling sections indicate bonding failure caused by moisture buildup or improper installation. If large areas have separated from the building, reinstalling the system ensures a strong and lasting bond.
Consider a Replacement if Your EIFS Are Old
EIFS materials wear down over time due to exposure to sunlight, temperature changes, and moisture. Signs of aging include surface erosion, fading, and brittle finishes. Replacing the EIFS restores insulation performance, improves appearance, and extends the life of the building.
Replace Your EIFS if the Structure Underneath is Weak
EIFS should provide a firm and stable exterior. If walls feel soft, sag in certain areas, or crumble when touched, the structure beneath may have deteriorated. A complete replacement addresses these underlying issues and reinforces the building.
Upgrade Your EIFS if Your System Lacks Proper Drainage
Older EIFS designs often lack drainage systems, causing moisture to become trapped behind the surface. Modern EIFS includes drainage features that allow water to escape, reducing the risk of mold and water damage. Upgrading to a newer system improves moisture control and long-term performance.
