Our house is about 24 yrs old. The banisters on the front balcony are starting to crack and crumble. My husband says they are cast stone material. We cannot find anyone in the Dallas TX area that is willing to fill the cracks or do any type of repair. Maybe we are contacting the wrong contractors. But it would be a small job. Any ideas on what we can do. If we have to replace the balcony railing and banisters what options are out there that is a newer product then cast stone. Any suggestions appreciated. Thank you!!
