Your sliding glass door is sticking, leaking cold air, or the glass is fogged beyond cleaning. You know it’s time to replace it — but before you call anyone, you want a ballpark number. That’s a smart move.
After 25+ years replacing patio doors and glass all across the Portland metro — Tigard, Beaverton, Tualatin, Sherwood, and beyond — we’ve seen every scenario. This guide gives you honest, grounded numbers so you know what you’re walking into before the first quote lands in your inbox.
What Does Sliding Glass Door Replacement Cost in the Portland Area?
National cost guides from sources like Angi, Bob Vila, and HomeGuide put the typical sliding glass door replacement range at $400 to $2,000 for a standard residential door, with the national average hovering around $1,700–$2,500 once labor is included. Portland area pricing generally tracks the national range, though labor rates in the Pacific Northwest run slightly higher than the national average.
Here’s the honest answer: most homeowners we work with in Tigard and the surrounding area land somewhere in the $800–$1,800 range for a standard two-panel patio door replacement — door, hardware, and installation included. Specialty glass, upgraded frames, or larger openings push that number up.
What Drives the Cost: The 5 Biggest Factors
1. Door Size
Size is the single biggest cost driver. A standard 6-foot door costs less than an 8- or 10-foot opening. Most residential patio doors fall in the 6- to 8-foot range. Larger doors require heavier panels, bigger frames, and more labor.
2. Frame Material
The frame material affects both price and long-term performance. Vinyl is the most popular choice for Oregon homes because it handles our wet winters well and doesn’t require painting or sealing.
| Frame Material | Typical Cost Range (door only) | Best For |
|---|---|---|
| Vinyl | $300 – $1,200 | Value, energy efficiency, low maintenance |
| Aluminum | $750 – $2,500 | Modern aesthetics, durability |
| Composite | $600 – $1,200 | Wood look without wood maintenance |
| Wood | $1,000 – $3,000 | Traditional homes, premium look |
| Fiberglass | $1,500 – $2,500 | Maximum durability, high-end builds |

3. Glass Type
Single-pane glass is largely a thing of the past for exterior doors. Most replacements today involve double-pane or triple-pane units. In Oregon’s climate, Low-E double-pane glass is the standard recommendation — it cuts heat loss significantly and qualifies for some energy efficiency rebates.
- Single-pane: $350 – $1,500 (door unit)
- Double-pane: $450 – $2,100 (door unit) — the most common choice
- Triple-pane: $2,000 – $3,000 (door unit) — worth it for north-facing or exposed walls
4. Number of Panels
Most residential sliding doors have two panels — one fixed, one sliding. Three- and four-panel configurations open up wider and look impressive, but the cost climbs fast. Per Angi’s data, two-panel doors run $400–$2,400, three-panel configurations jump to $1,500–$5,000, and four-panel systems run $2,500–$7,000.
5. Labor and Removal
Professional installation typically runs $70–$100 per hour, with most standard replacements taking 2–5 hours. Removal and disposal of the old door adds another $100–$250 in most cases, though many contractors include this in the overall quote. Ask upfront so you’re comparing apples to apples.
Repair vs. Replace: How to Know Which One You Need
Not every problem requires a full replacement. Here’s a quick breakdown:
- Rollers or tracks worn out: Repair cost is typically $75–$300. Worth fixing if the door and glass are otherwise sound.
- Fogged glass (failed seal): Glass panel replacement runs $300–$1,200 per panel. Often the right call if the frame is still in good shape.
- Frame damage, rot, or warping: Full replacement is usually the better value at this point.
- Door is 15–20+ years old: Energy performance alone often justifies full replacement — modern Low-E glass can meaningfully reduce heating bills in a Portland winter.
If you’re not sure which category your door falls into, a quick in-person look from a glazier beats guessing. We’re happy to give you a straight answer.
Portland Area Cost Considerations
A few things specific to the Pacific Northwest affect your price:
- Energy efficiency matters more here. Our mild but persistently wet and cool winters mean Low-E glass and tight weatherstripping pay for themselves faster than in drier climates.
- Labor rates run slightly above national average. Oregon wages and contractor overhead are higher than states like Texas or Georgia. National averages from Angi or HomeAdvisor are a useful reference, but expect Portland area quotes to land at or slightly above those midpoints.
- Permits are rarely required for a same-size door replacement — you’re swapping door for door without structural changes. Adding a new opening or changing the rough opening size is a different story.
Get Your Exact Price
The ranges above give you a solid starting framework, but your actual cost depends on your specific door opening, the product you choose, and what the installer finds when the old door comes out.

Frequently Asked Questions
How much does it cost to replace a sliding glass door in the Portland area?
Most standard residential sliding glass door replacements in the Portland metro run between $800 and $1,800 installed, including the door unit, hardware, and labor. Specialty glass types, larger openings, or premium frame materials can push costs higher. Use our free estimator tool for a project-specific range.
Is it cheaper to repair or replace a sliding glass door?
It depends on what’s wrong. Roller and track repairs typically run $75–$300 and are worth doing on a door that’s otherwise in good shape. If the frame is damaged, the glass is fogged from a failed seal, or the door is more than 15–20 years old, a full replacement usually delivers better value over time — especially given modern energy efficiency improvements.
How long does sliding glass door replacement take?
A standard same-size replacement is typically a half-day job — 2 to 5 hours from start to finish for a single door. The old door comes out, the new one goes in, and we clean up after. There’s no drywall work or structural modification needed for a like-for-like swap.
What is the best frame material for a sliding glass door in Oregon?
Vinyl is the most popular choice in the Pacific Northwest because it handles moisture well, requires no painting or sealing, and performs well in our cool, wet winters. Aluminum is a strong second choice for modern homes or commercial applications. Wood looks great but requires more ongoing maintenance in our climate.
Do I need a permit to replace a sliding glass door in Portland or Tigard?
In most cases, no. A like-for-like sliding glass door replacement — same size, same location — does not require a permit in the Portland area. Permits are typically required only when you’re changing the size of the opening or making structural modifications. When in doubt, your installer should be able to confirm this for your specific project.
