If your Northern Virginia home has windows that are fifteen years old or more, you've probably noticed drafts, condensation between panes, or energy bills that keep climbing. Replacing those windows is one of the most impactful investments you can make in your home, but understanding the true cost before you commit's essential. At Nest Exteriors, we believe informed homeowners make better decisions, so here's a transparent breakdown of what window replacement actually costs in the Northern Virginia and DC Metro market.
Average Per-Window Costs in Northern Virginia
Window replacement pricing varies widely depending on the window style, frame material, glass package, and how complex your installation is. Here's a general range for the NoVA market as of 2026.
Vinyl Windows
Vinyl remains the most popular frame material in the region because it balances performance and value well. For a standard-sized double-hung vinyl replacement window, including professional installation, homeowners in Fairfax, Loudoun, and Prince William counties typically spend between $450 and $950 per window. Premium vinyl options with upgraded glass packages and hardware can push costs closer to $1,100 per window.
Fiberglass Windows
Fiberglass frames offer superior strength and barely expand or contract through Northern Virginia's temperature swings between summer and winter. Expect to pay between $700 and $1,400 per window installed for fiberglass options. ProVia's Endure series, which we install frequently for homeowners in areas like Arlington and Alexandria, falls in this range and delivers outstanding thermal performance with a clean architectural look.
Wood and Wood-Clad Windows
For historic homes in neighborhoods like Old Town Alexandria or parts of Leesburg where architectural character matters, wood and wood-clad windows from manufacturers like Pella start around $900 per window and can exceed $1,800 for custom sizes and configurations. These products need more maintenance but offer an aesthetic that vinyl and fiberglass can't perfectly replicate.
Costs by Window Style
The style of window you choose has a real effect on your per-unit price.
Double-hung windows are the most common style in Northern Virginia homes and generally fall on the lower end of the price spectrum for each frame material. Their straightforward design and widespread availability keep costs in check. Casement windows, which crank open on a hinge, typically cost ten to twenty percent more than a comparably sized double-hung because of the more complex hardware mechanism. That said, their superior air sealing can offset that premium through energy savings over time. Picture windows and other fixed (non-operable) windows tend to cost less than operable styles since they have no moving parts. A large fixed window can run $350 to $800 depending on size and glass package. Bay and bow windows represent the highest per-unit investment. A three-lite bay window installed in Northern Virginia typically costs between $2,500 and $5,500, factoring in the structural support and more involved installation work. Sliding patio doors and French patio doors are separate categories, but if you're replacing both windows and doors in a single project, bundling them together often results in better overall pricing.

Most homeowners don't replace just one window. A whole-home window replacement project for a typical three-bedroom, two-story Colonial in Fairfax or Loudoun County involves ten to twenty windows. Here's what you can expect for total project costs.
| Project Scope | Estimated Cost Range |
|---|---|
| 5-8 windows (partial replacement) | $3,500 - $9,000 |
| 10-15 windows (most of the home) | $7,000 - $18,000 |
| 16-25 windows (full replacement) | $12,000 - $30,000+ |
Factors That Affect Window Replacement Cost in Northern Virginia
Window Size and Configuration
Standard-sized windows cost less than oversized or custom units. If your home has non-standard openings, which is common in older homes throughout Falls Church, Vienna, and McLean, expect to pay more for custom-manufactured windows that fit correctly.
Glass Package and Energy Efficiency
A basic double-pane insulated glass unit costs less than a triple-pane unit with low-emissivity coatings and argon gas fill. The energy savings from a higher-performing glass package often pay for the upgrade within a few years, though, especially given Northern Virginia's hot summers and cold winters. Our energy-efficient windows guide walks through the details of U-factor, SHGC, and what to look for in the DC Metro climate.
Installation Complexity
Several factors can increase installation labor costs in the Northern Virginia market:
- Accessibility: Second and third-story windows, or windows above a roof line, require ladders, scaffolding, or other equipment that adds cost.
- Structural repairs: If the rough opening, sill, or surrounding framing has rot or water damage, that needs to be fixed before a new window goes in. This is especially common in homes that have experienced flashing failures or siding issues.
- Permit requirements: Some Northern Virginia jurisdictions require permits for window replacements, particularly if the opening size is changing. Fairfax County, for example, has specific requirements when windows are modified beyond a like-for-like swap.
- Lead paint remediation: Homes built before 1978 may require EPA-certified lead-safe work practices, which adds cost and time to the project.
Brand and Manufacturer
Not all window brands are created equal. At Nest Exteriors, we install ProVia and Pella windows because they consistently deliver on durability, energy performance, and warranty coverage. Here's how they generally compare on price.
ProVia offers exceptional value in the mid-range to premium segment. Their Aspect series provides strong performance at a competitive price point, while the Endure fiberglass line competes with products costing significantly more from other manufacturers. ProVia windows are made in the USA and come with a transferable limited lifetime warranty. Pella covers a broad spectrum from their value-oriented lines to their premium wood and fiberglass collections. Pella's Lifestyle series offers wood interiors with a low-maintenance aluminum-clad exterior, a popular choice for homeowners in Northern Virginia who want the warmth of wood without the upkeep burden.Seasonal Timing
The window replacement market in Northern Virginia has seasonal fluctuations. Spring and early fall are peak seasons when demand is highest and wait times can stretch. Scheduling your project in late fall or winter can sometimes yield better pricing and faster turnaround, though installation crews need to account for weather conditions.
What About Financing?
A full window replacement project is a significant investment. Many Northern Virginia homeowners take advantage of financing options to spread costs over time. At Nest Exteriors, we offer flexible financing plans so you can start enjoying the comfort and energy savings of new windows without paying the full amount upfront. We also help identify any applicable rebates or tax credits, including federal energy efficiency incentives that may apply to qualifying window products.
The Hidden Costs of Waiting
While the upfront cost of window replacement is real, there are ongoing costs to keeping old, underperforming windows. Drafty windows force your HVAC system to work harder, and that shows up on every monthly energy bill. Condensation and failed seals can lead to water damage and mold issues that become far more expensive to fix than the window replacement itself. From a property value standpoint, outdated windows are one of the first things buyers notice in the competitive Northern Virginia real estate market.
How to Get an Accurate Estimate
Online pricing guides, including this one, give you useful ranges, but the only way to know exactly what your project will cost is a professional in-home assessment. A qualified estimator will measure your windows, evaluate the condition of the openings, discuss your priorities for energy performance and aesthetics, and provide a detailed written proposal.
At Nest Exteriors, our estimates are free, thorough, and come with no pressure. We measure every opening, photograph the existing conditions, talk through the product options that make sense for your specific home and budget, and present clear pricing with no hidden fees.
