You should contact the Area Agency on Aging. In your area, you should contact Legacy Link. It is located at 508 Oak Street Suite 1, Gainesville, GA 30501, (770)538-2650. You can also use the Elder Care Locator to find resources. The national toll free number, which routes the call to your area, is 1-800-677-1116. You might also contact local churches. Many of them will have funds set aside to assist individuals who are in need and many will have volunteers who might do the work.
In addition to many local charitable organizations and churches there are numerous agencies and councils that plan, provide, develop and coordinates services for all people 60 years of age and older. You may start with the Atlanta Regional Commission. This Area Agency on Agency can provide you with information, guidance, and support. I am not sure if they offer assistance in your home repairs. They can also make referrals to local resources.
