Energy Upgrade Package
Your combination of glass upgrades and current glass type qualifies as an energy upgrade package. This focuses on maximizing thermal performance while retaining existing frames, delivering the best return on energy savings.
1--2 days
6 windows is a comfortable project for a skilled crew over 1--2 working days.
Upgrading double-pane glass with Low-E coating and gas fill typically saves 10--15% on energy costs. The improvement is most noticeable in summer cooling and winter comfort.

Your Project Breakdown
Each factor below contributes to your overall project cost. Understanding these helps you make informed decisions about where to invest and where to save.
Standard window styles have straightforward replacement processes.
6 windows -- a moderate-sized project typical for most homes.
1 upgrade selected. Energy upgrades improve comfort and reduce utility costs.
Good frames allow for glass-only replacement, the most streamlined option.
Education
Single-hung, double-hung, sliding, and picture windows are the most common and cost-effective to replace. Their standard sizing and straightforward installation make them the baseline for window replacement projects.
Hinged windows offer excellent weathersealing and ventilation control. They require more precision in hardware alignment and installation, which adds moderate complexity to the project.
These multi-panel windows project from the wall and create a dramatic architectural feature. Their complex geometry, structural requirements, and custom fabrication make them the most involved replacement projects.
The glass itself is the most important factor in energy performance. Low-E coatings, argon gas fill, and multi-pane configurations dramatically reduce heat transfer. The glass upgrade you choose affects both upfront cost and long-term savings.
Our Process
We evaluate seven key factors that influence window replacement costs: window count, style, current glass, desired upgrades, frame condition, home type, and accessibility. Each factor is weighted based on its real-world impact on project scope and labor.
Rather than guessing at prices that vary widely by market, material, and season, we show you a relative cost level and break down exactly which factors are driving your project higher or lower. This gives you actionable insight for planning conversations.
Based on your specific combination of inputs, we generate targeted recommendations, energy savings estimates, and timeline projections. For exact pricing, our team provides free on-site assessments with no-obligation quotes.
FAQ
Window replacement costs vary significantly based on brand, material, current market conditions, and installation specifics that can only be assessed on-site. Rather than providing inaccurate estimates, we show you the relative cost factors so you understand what drives pricing. Our free on-site assessment gives you an exact quote tailored to your home.
Glass-only replacement (also called "insert" replacement) fits new glass into your existing window frame. It is faster, less invasive, and less expensive. Full-frame replacement removes everything -- including the frame, casing, and trim -- and installs a completely new unit. This is necessary when frames are rotted, warped, or structurally compromised.
For most DMV homeowners, Low-E coating is the single best upgrade you can make. It reflects heat in summer and retains warmth in winter, typically improving energy efficiency by 30-50% compared to standard clear glass. The coating is invisible and does not significantly reduce natural light. It pays for itself through energy savings within a few years.
A skilled crew can typically replace 4-8 standard windows per day. More complex windows like bay/bow or casement styles take longer per unit. Frame replacements add time as well. Most residential projects of 6-10 windows are completed in 1-2 days. We protect your home with drop cloths and clean up thoroughly at the end of each day.
In most DMV jurisdictions, replacing windows in the same size opening (glass-only or insert replacement) does not require a permit. However, changing the size or location of a window opening, or performing structural modifications, typically does. Historic districts may have additional review requirements. We handle all permit requirements as part of our service.
The federal Inflation Reduction Act offers tax credits for qualifying energy-efficient windows. Windows must meet ENERGY STAR Most Efficient criteria. Additionally, local utility programs through Dominion Energy, DCSEU, and EmPOWER Maryland may offer rebates. We can help you select products that qualify for available incentives.
