Statement of Conditions that Affect EIFS Homes The following cost data and repair statistics were garnered from information gathered by Stucco Retro™ over the last three years. For this cost estimate the repair cost of sheathing and framing will remain constant. A cost of $12.00 per square foot* is used. Working from this information and information available on the NAHB website, we offer the following information as a means to inform those that may have similar situations. According to the National Association of Home Builders the areas on EIFS homes that lack diverter flashing have a 78% chance of sheathing or structural damage. They also state that 45% of the windows tested on EIFS home also suffered the same type damage below the windows. The average home has five diverters and there are an average of forty windows. Diverter Flash Repair Cost From the above data we assume there will be average of four diverters that have damage. These areas will have approximately 30 square feet each of damage for a total of 120 square feet.
This is an average of less than $3,000.00 for the diverter flash problem. If properly installed, the problem should be solved and should not reoccur. Window Repair Cost The average cost to repair or replace window units per home including new metal head flash and the installation of proper bond breaker sealant joints.*** The repair cost to sheathing and framing** 40 units at 20 square feet of damage at 45% as stated in NAHB = 360 square feet.
