How much does window replacement cost in Virginia?

There is no one price for window replacement in Virginia. Where your project lands depends on how many windows you replace, their size and frame material, how they are installed, whether the house is old enough for lead-safe rules to apply, and what the installer finds when the old windows come out. The most reliable number is a written quote for your own windows.

ENERGY STAR also points out that different dealers may quote different prices for the same product,^[2] so the quotes you collect matter more than any single average.

What drives the price

How many windows. ENERGY STAR advises planning to buy at least 10 windows to get the best price per window, because the time it takes to haul the windows, set up and clean up is spread over a larger job.^[1] One window on its own usually costs more per window.

Size, style and frame material. Larger windows and specialty shapes usually cost more than standard sizes. Andersen, which makes vinyl-clad rather than all-vinyl windows, notes that vinyl windows are typically the least expensive upfront, depending on the product and manufacturer.^[6] Efficiency adds less than people expect: certified windows may cost more than non-certified ones, but the labor should be about the same for both.^[2]

Insert or full-frame installation. An insert window fits inside the existing frame and can save money and keep your trim.^[5] A full-frame replacement removes the old frame down to the rough opening, which means more labor and new interior and exterior trim, but it is the right call when the frame is rotted or badly out of square. See how to measure for replacement windows to check your own frames.

The age of the house. Under the EPA's lead rule, anyone paid to do work that disturbs paint in a home built before 1978 must be certified, and window replacement is always covered regardless of how much paint is disturbed.^[4] Containment, cleanup and disposal add time, so expect it in the price, and be wary of a quote from a firm that does not mention it.

Hidden repairs. Rotted sills, damaged sheathing or missing flashing often turn up only when the old window is out. Ask how each contractor prices that work before you sign.

Everything else on the bill. Andersen's support page lists the extras plainly: installation costs can include labor, permitting, disposal fees and more.^[7] Upper-storey windows, masonry openings, interior trim and painting also add cost.

Timing. Plan ahead: high-performance windows often take 6 to 8 or even 12 weeks to arrive after ordering, because they are made to order.^[1]

Permit costs

Most like-for-like replacements carry no permit fee at all. Virginia's building code needs no permit for replacing windows with windows of similar operation and opening dimensions that do not require changes to the existing framed opening.^[8] There are exceptions: a building official may require a permit for replacement windows in a locally designated historic district or in a special flood hazard area.^[8]

When the job does need a permit, such as a wider opening, the fee is set locally. As an example, when we checked on October 27, 2026, Montgomery County's fee for residential alterations was $0.22 per square foot with a $45 minimum, plus a technology fee of 2% of fees with a $10 minimum.^[9] Do I need a permit to replace windows in Virginia? covers when one applies.

What you get back

New windows save some energy, but rarely enough to cover their cost on their own. ENERGY STAR says: "Replacing old windows with ENERGY STAR certified windows lowers household energy bills by an average of up to 13 percent nationwide when replacing single-pane windows."^[2] It also says plainly that new windows may not pay for themselves in energy savings alone.^[1] Comfort, easier operation, less maintenance and fixing water or rot problems are often the better reasons.

If your windows are sound but drafty, storm windows are worth pricing. ENERGY STAR certified storm windows cost one-half to one-quarter as much as common replacement windows,^[1] and low-e storm windows can save about 20% on annual heating and cooling bills when installed over single-pane clear glass windows.^[1]

Credits, rebates and help

ENERGY STAR lists the federal windows tax credit as effective for products purchased and installed between January 1, 2023, and December 31, 2025,^[3] so do not count on it for a job done now; ask a tax professional about your own return. Rebates for windows may be available through your local utility,^[1] so check your power or gas company's site before you sign. For lower-income households, the Department of Energy's Weatherization Assistance Program can include repairing windows or replacing a few damaged windows for households that qualify by income, but generally does not replace a whole house full of windows.^[1]

Comparing quotes fairly

Ask every installer to quote the same windows, the same installation method and the same trim work, with labor and materials shown separately. Reputable companies will give you an estimate that is good for at least 30 days,^[1] so be cautious of a price that is only good today.

Check the licence on DPOR's lookup. Under Virginia law, a Class C licence covers a single contract over $1,000 but less than $30,000, and Class B covers $30,000 or more but less than $150,000.^[10] For residential work, the Board for Contractors requires a written contract that includes, among other things, the total cost, the amounts and schedule of progress payments including the down payment, a list of the materials and work, and a statement that the contractor will comply with local permit, inspection and zoning requirements.^[11]

Stop and call a pro if

• The sill or frame is soft, stained or crumbling, or there are water stains on the wall below the window.
• You want a bigger opening, a new window where there was none, or a bedroom window that meets egress rules.
• The house was built before 1978 and the old windows or trim are painted.
• The windows are above the first floor or set in brick or stone.
• The house is in a historic district, where approval may be needed before the work.
