Door repairs vary depending on the type of damage. You can plug holes up to a half-inch wide with wood putty or two coats of auto-body filler, which costs about $5 to $15 at your local hardware store. Allow the filler to dry entirely before smoothing out and painting. To remove 1/8-inch off the edge of a door in an existing frame, repair prices start at around $15. If you need to replace or reframe the door, the cost can increase to $1,000.
To refurbish an old wooden front door, remove it from the hinges and lay it flat. Then, remove all hardware and existing finishes to prepare it for sanding. Once it’s sanded, clear off any sawdust and apply stain. After it dries, apply exterior varnish, reinstall all hardware, and re-hang it on its hinges.
Wood filler is easy to use and can repair cracks, holes, and dents in as little as two hours. First, put the wood filler directly into the hole you want to fill and rub it in a circular motion. Use an angled putty knife to scrape across the surface to smooth out any excess. Once the hole is filled, use sandpaper to smooth the surface.
