It is common to have to remove part of a floor when doing a remodel. In the case below a kitchen island was moved and new plumbing and electrical were added. See the photos to see how we repaired this floor.
You can see the part of the floor that we had to remove. Also note the new plumbing electrical and HVAC.
Here we have new planks in repaired area.
Here you can see that most of the floor has been sanded at an angle. Why at an angle? Because the sander bites harder when angled this way making each pass more efficient. After several sandings and after the cabinets are installed the floor will will be stained to match the existing flooring.
