ServiCover📌 Key Takeaway: Sliding patio doors typically cost $700-$6,200 installed, and French doors $550-$5,600. Frame material, glass package and whether the opening needs resizing drive the range.
Sliding vs. French Doors
| Factor | Sliding Patio Door | French (Hinged) Doors |
|---|---|---|
| Installed cost | $700-$6,200 | $550-$5,600 |
| Space needed | None — panels slide | Swing clearance inside or out |
| Opening width | One panel opens | Both doors can open fully |
| Look | Modern, large glass | Traditional, classic |
Frame Materials
| Material | Strengths | Trade-offs |
|---|---|---|
| Vinyl | Affordable, low maintenance | Fewer color options; can expand in heat |
| Fiberglass | Strong, stable, efficient | Higher cost |
| Aluminum | Slim frames, lots of glass | Conducts heat unless thermally broken |
| Wood / clad-wood | Warm look inside | Highest cost; exterior cladding needed |
Glass Options Worth Considering
- Low-E coatings to reduce heat gain and fading
- Double or triple panes for insulation and noise
- Impact-rated glass in hurricane zones
- Built-in blinds between the panes for easy cleaning
Frequently Asked Questions
Can I replace a sliding door with French doors?
Often yes, if the opening width fits a French door unit and there's swing clearance. Resizing the opening adds framing costs.
Do patio doors need a permit?
Same-size replacements often don't; enlarging an opening typically does. Check your local rules.
