Tearing out a wall to add a sliding glass door can transform a room, creating an open and bright space. Start by ensuring the wall isn’t load-bearing. If it is, consult a professional to avoid structural issues. Turn off power to the area and remove drywall, studs, and insulation. Prepare the rough opening for the sliding door, ensuring it's level and square. Install the door according to the manufacturer’s instructions, then finish by adding trim and sealing any gaps.
