Nine months ago I moved into a new home. Our builder made a mistake, and as a result, had to add some colored stucco to fill in the area that was repaired. The stucco on the repired area does not at all match the rest of the wall. The person sent out to make the repair said it is impossible to get a perfect (or even a closer) match. Is this true? Is there anything that can be done to correct this and have the side of my new home look right?
