We had a similar issue and called a company called “Bay Area Sliding Door Repair”. Home page
Tampa Sliding Door Repairs | Bay Area Sliding Door Repairs | Free Quote and their phone # is 813.712.0211. They have a flat fee for each door based on the number of doors you have to repair. They came out, removed the doors, replaced the rollers on the bottom with stainless steel rollers, cleaned the tracks, installed the doors and aligned them for proper operation.
They told us to NOT EVER pressure wash the tracks or place any lubricant on them. This will only attract dirt and sand from blowing/raining storms. Since we have had them out we’ve been very satisfied with their work. Straight up front with the prices no matter how much time they need to spend. One of the technicians were the owner’s son. They were very polite and up front about what people experience with sliding doors. This is about all they do and travel from Lutz, Florida to all the beach communities. We live in Inverness, Florida and they traveled from Lutz to service our doors which is about 50 miles. Did a great job and told us if we have any other problems they’ll come out and make it good. This was done in 2020. Would recommend them to anyone.
