We do one thing - sliding glass door repair - and we do it well.

Repair, not replace

We don't sell new sliding glass doors. We don't replace windows or install new window units. We don't service French, swing, or hinged patio doors, shower doors, garage doors, automatic or commercial entrance sliders, or screen-only enclosures. Specializing has made us better at this one job than companies that try to do everything — and it removes the upsell pressure that homeowners feel from contractors with a fleet of replacement units to move.

Built for the coast

We've serviced thousands of sliding glass doors from Atlantic Beach to Daytona Beach. We know which brands fail how, which neighborhoods need salt-rated hardware, and which problems are quick fixes vs. genuine replacements. Coastal Florida is a hard environment, and we've built our repair process around it: stainless rollers, stainless track caps, salt-rated mortise locks, and Florida-fabricated insulated glass.

Honest pricing, written down

Every quote is flat-rate and written before we start. No hourly billing, no surprise charges, no upsells you didn't ask for. If we can't fix it, you don't pay for the diagnostic visit. 2-year parts and service warranty on every repair.

Our philosophy: fix what works, replace only what doesn't

The replacement industry has a strong financial incentive to sell you a new $5,000 door. We have the opposite incentive: we want you to keep the door you have and tell your neighbors how we fixed it for $400. Over time that has shaped what we do and what we refuse to do.

We refuse to upsell unnecessary parts. We refuse to quote replacement when repair will hold for another decade. We refuse to install cheap mild-steel rollers in coastal homes just because the customer didn't ask about hardware grade. And we refuse to send a single technician to do work that genuinely needs two pairs of hands.

Technician training and parts standards

Every First Coast technician is trained in-house specifically on sliding glass door systems - not as a side specialty within a broader handyman or window company. New techs spend a minimum of 60 days riding with senior technicians before running their own service calls. We train on brand-specific quirks (PGT vs CGI roller carriages, Pella mortise body torque specs, Andersen Perma-Shield gasket compatibility) because shortcuts on a 200-pound glass panel are how people get hurt and how doors get destroyed.

Our parts standard is simple: stainless when corrosion is the failure mode, OEM-equivalent when brand fitment matters, and never the cheapest available option. The $4 generic mortise lock you can buy on a parts site will work for 18 months and fail. The $35 hardened, salt-rated mortise we install will outlast the door itself.

Why we exist

Sliding patio doors are one of the most under-served categories in home repair. Most window-and-door companies treat sliders as a replacement opportunity, not a repair category - which means a homeowner with a sticky door has a hard time finding anyone willing to come fix the rollers for $300 when there's $5,000 worth of new-door margin available instead. We built First Coast to be the company that picks up the phone, comes out, fixes the actual problem, and charges what the work is worth.
