These sliding glass doors had already had the rollers replaced, but they still would not slide properly. Sometimes, replacing the rollers alone is not enough. In this case, the real problem was that the floor was uneven.
The client tried to fix the issue by changing the rollers himself, but he eventually gave up because he couldn’t figure out what was wrong. After that, he decided to hire us.
When we arrived, we discovered the problem right away. We removed the doors and raised the floor by installing an extra track. Then, we filled the area with cement to level it and make the doors straight.
Once the floor was properly leveled, the rollers were finally able to do their job. Now, the doors slide smoothly and work like new again.
