The Honest Cost Comparison
Before deciding, you need real numbers. Here's what repairs and replacement actually cost in Broward County:
| Issue | Repair Cost | Replace Cost | Verdict |
|---|---|---|---|
| Worn/grinding rollers | $150–$300 | $800–$2,500+ | Repair |
| Bent or damaged track | $200–$450 | $800–$2,500+ | Repair |

Problems That Are Always Repairable
These four issues represent 90%+ of sliding door complaints in Broward County. All are mechanical components that can be serviced or replaced without touching the door frame or glass:
Rollers and Wheels
The most common sliding door repair in South Florida. Rollers are a serviceable component — they're accessed by lifting the door panel off the track via the adjustment screws. Replacement takes 45–90 minutes and costs $150–$300 including labor. Even on a 20-year-old door, roller replacement restores smooth operation for another 5–10 years.
Track Repair and Resurfacing
Bent, corroded, or grooved track is repairable in most cases. Minor bends are straightened with a track-forming tool. Heavily grooved tracks can be resurfaced or a new track liner installed. Full track section replacement is also possible without removing the door frame. Cost: $200–$450 depending on severity and track length.
Lock and Handle
Sliding door locks (hook-bolt, multi-point, or latch style) and handles are all field-replaceable. The mechanism mounts to the door stile with 2–4 screws. Replacement cost runs $120–$250 including parts and labor. We keep most major brands (PGT, CGI, Andersen, Milgard) in stock for same-day repair.
Glass Replacement (Non-Impact Panes)
Fogged dual-pane glass (the IG unit has failed, allowing moisture in) or a cracked single-pane can be replaced without touching the frame. We measure on-site, source the glass, and return to install — usually within 5–7 business days. Cost: $300–$600 per pane. Note: if the door is impact-rated, cracked impact glass must meet Florida code requirements on replacement.
The 7 Situations Where Replacement Wins
These are the scenarios where investing in repair extends the problem rather than solving it. Be honest with your technician — and ask for a frame inspection before committing either way:
Hurricane debris impact, a forced-entry attempt, or years of settling can bend the door frame's vertical stiles or crack the corner welds. A bent frame means: the door won't seal (water intrusion risk), rollers bind and fail prematurely, and the glass sits under stress. Frame repair is not reliable — replacement is the only structurally sound fix.
If you're pulling a permit for any renovation involving the sliding door opening, Florida Building Code requires the replacement door to meet current wind-load and impact standards for Broward County's wind zone (140–160 mph design pressure). A non-impact door installed before 2002 will not pass inspection as-is. If code compliance is triggered, you must replace with an FPA-rated impact door.
Impact glass is a laminated assembly — the inner PVB interlayer holds the glass together after impact, but once cracked, the door no longer meets its rated protection level. Replacing just the laminated glass unit is possible but requires Florida Product Approval-rated glass matched to the door's existing test report. If the door is very old or the manufacturer no longer supports it, full door replacement may be the only code-compliant path.
When rollers, track, lock, and weatherstrip all need work simultaneously on a 25+ year old door, the economics shift. You're investing $600–$900 in repairs on a door that may need the same again in 3 years as the remaining original components fail. In this scenario, replacement amortizes better — particularly if you upgrade to an impact door and gain hurricane protection, insurance premium reduction, and energy efficiency.
On canal-adjacent or oceanfront Broward County homes, the embedded track can corrode deeply into the concrete sill, making extraction and replacement extremely labor-intensive. When the repair estimate for track work alone exceeds $800, full door replacement (which includes a new track and sill seal) often pencils out at a similar total cost with a significantly better outcome.
If your primary driver is reducing air conditioning costs, replacement with a low-E impact door (SHGC rating 0.23–0.32) can meaningfully reduce solar heat gain through the glass in a Florida climate. Repair preserves the existing glass performance but doesn't improve it. This isn't a reason to replace on its own — but if you're already replacing for structural or code reasons, spec the best glass performance you can afford.
Florida homeowners with non-impact sliding doors often pay $800–$2,000/year more in windstorm insurance premiums than those with fully impact-protected openings. If replacing a non-impact slider with a Florida Product Approval impact door closes your last unprotected opening, the insurance savings can pay back the replacement cost in 3–5 years. Ask your insurer for a mitigation credit estimate before deciding.
How to Tell If Your Frame Is Sound (The Free Test)
Before calling anyone, do this 60-second inspection:
- Check the corner welds. Look at the four corners of the door panel where the aluminum stiles and rails meet. Cracks, gaps, or visible separation indicate frame failure.
- Check the frame square. Measure diagonally corner-to-corner both ways. If the measurements differ by more than ½ inch, the frame is racked (out of square) — a red flag for structural compromise.
- Run your hand along the frame. Bends, kinks, or visible ripples in the vertical stiles mean the frame took an impact load at some point.
- Slide the door fully open and closed. If the door binds only in specific positions (not throughout the travel), the issue is almost always the rollers or track — not the frame.
- Check the glass edge. At the perimeter of the glass where it meets the glazing bead, look for cracks running from the corner. Corner cracks in tempered glass indicate frame stress — not just impact damage.
If the frame passes these five checks, you almost certainly need a repair, not a replacement. If it fails two or more, call for an estimate with an explicit frame-integrity assessment.
The Florida Building Code Factor (Broward County)
Broward County sits in the High Velocity Hurricane Zone (HVHZ) — one of only two counties in the US with this designation (Miami-Dade is the other). This matters for sliding doors because:
- Any permitted replacement of a sliding glass door must use an HVHZ-approved impact product with a Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval (FPA).
- Standard "impact-rated" doors sold in other Florida counties may NOT meet HVHZ requirements — verify the NOA or FPA number before purchasing.
- Repair work (rollers, tracks, locks, glass-in-kind replacement) generally does NOT require a permit in Broward County — it's maintenance, not alteration. This preserves your option to repair economically without triggering a full code upgrade.
- If you do need to replace: Budget $1,500–$4,000 installed for an HVHZ-compliant impact sliding door. PGT, CGI, and Simonton all make popular HVHZ-approved products with local dealer networks in Broward.
Broward County Homeowners: Unpermitted Non-Impact Replacement = Serious Risk
Replacing a sliding glass door without a permit in Broward County (to avoid the code upgrade cost) can result in a stop-work order, mandatory removal, and difficulty selling the home. Home inspectors specifically look for non-code-compliant openings. If you're weighing unpermitted replacement vs repair, choose repair every time — it's legal, warrantied, and doesn't create a cloud on your title.

Frequently Asked Questions
When should I repair vs replace a sliding glass door in Florida?
Repair is the better choice when: the frame is structurally sound, the glass is intact, and the issue is limited to rollers, track, lock, or handle. In Broward County, repairs cost $150–$450 vs $800–$2,500+ for full door replacement. Replace when: the frame is bent or cracked, the existing door doesn't meet Florida's current impact/hurricane code, the glass is impact-rated and cracked (must replace the full IG unit), or when the door is more than 25 years old and multiple components are failing simultaneously.
How much does sliding door repair cost vs replacement in Broward County?
Sliding door repair in Broward County costs $150–$450 for most common repairs (rollers $150–$300, track $200–$450, lock/handle $120–$250, glass replacement $300–$600 per pane). Full sliding door replacement costs $800–$2,500 for the door unit alone, plus $300–$800 for professional installation. Impact-rated or hurricane sliding door replacement runs $1,500–$4,000+ installed. Unless the frame is structurally compromised or you need to meet current Florida building codes, repair is nearly always more cost-effective.
Does Florida law require impact glass when replacing a sliding door?
Yes, in most of Florida (and all of Broward and Miami-Dade counties), replacing a sliding glass door requires the new door to meet the current Florida Building Code wind-load and impact requirements for your specific wind zone. This means installing a Florida Product Approval (FPA) rated impact door, or protecting the opening with storm shutters. Simply swapping the glass or frame with non-impact materials is not code-compliant in Broward County.
What sliding door problems can be repaired without full replacement?
Most sliding door problems are repairable without full replacement: roller replacement ($150–$300), track repair or resurfacing ($200–$400), lock mechanism replacement ($120–$250), handle replacement ($80–$200), weatherstrip/seal replacement ($100–$200), non-impact glass replacement ($300–$600 per pane), and screen door repair ($75–$200). These repairs address 90%+ of sliding door complaints in Broward County.
Is it worth repairing an old sliding glass door in South Florida?
For doors built after 2002 that meet Broward County's impact requirements, repair is almost always worth it — the frame and glass represent most of the value. For pre-2002 non-impact doors, repair makes sense if the frame is structurally sound and you are not triggering a permit that requires code compliance. We always disclose the code situation during the estimate so there are no surprises.
Can a bent sliding door frame be repaired?
Minor bends in the vertical stile of a sliding door frame can sometimes be reshaped, but significant bends, corner-weld failures, or mid-rail cracks are not reliably repairable. Once the structural geometry of the frame is compromised, the door will not seal properly, the rollers will bind, and the glass sits under uneven stress. In these cases, replacement is the correct answer.
Not Sure Whether to Repair or Replace?
We'll come out, inspect the frame, and give you an honest estimate — at no charge. Most sliding door issues in Broward County are fixable for under $350.
