Large stains on wooden floors can be fixed by sanding, bleaching and refinishing the damaged parts to match the rest of the floor. As the process is relatively tedious and complicated, it's best to hire a home service pro to get the job done.
I am a general contractor and I hired Care Floor Systems for a concrete polishing for a commercial unit in Waterloo.
Juan and Carlos Lima performed and amazing job changing a concrete slab into a beautiful shiny floor.
They were very committed...
