If you live in Ashburn and you have asked three window companies for a quote, you have probably seen prices swing from $400 to $1,200 per window for the exact same opening. That gap is brand, install method, and frame material. This page is the honest pricing reference DreamHome uses on actual 2026 Ashburn window jobs, organized by window count, material, and install method. The number on the page is the number on the contract.

Ashburn VA Window Replacement Pricing by Material (2026)
Ashburn’s planned communities, large suburban colonials, and townhome blocks were built almost entirely between 1995 and 2015. Most Ashburn window installations we work on are in their second or third lifecycle, which means the pricing below reflects what we actually quote on real Ashburn homes in 2026.
Ashburn permit fees through Loudoun County run $90 to $240 depending on scope. All DreamHome estimates include the permit pull, the Loudoun County inspection coordination, and the final sign-off paperwork. You do not coordinate the inspector. We do.
What Drives Windows Cost in Ashburn, VA
Two identical-looking Ashburn homes can quote $4,000 apart for legitimate reasons. Here is what actually moves the number.
Window Count and Size
Ashburn ranches average 8 to 12 windows. Split-levels average 10 to 14. Ashburn colonials average 12 to 18. Larger custom Ashburn homes run 18 to 30. Standard openings (3’x5′) price per the table above. Oversize openings, picture windows, and geometric specialty shapes price separately.
Frame Material and Brand
ProVia ecoLite is the value tier — energy-rated vinyl with proper foam insulation and lifetime warranty. ProVia ENDURE is the premium tier — foam-filled frame, triple-pane glass option, and the highest impact and acoustic ratings available in vinyl. Wood-clad and fiberglass options run 40 to 80 percent above ENDURE pricing and are quoted on request for historic Ashburn homes.
Install Method
Retrofit install (also called insert install) keeps the existing frame and inserts the new window into the opening. It is faster, cheaper, and works in most Ashburn homes where the existing frame is sound. Full-frame install removes the old window down to the rough opening, replaces flashing, and rebuilds trim. It costs 30 to 50 percent more but is required when frames are rotted, the opening is being resized, or premium air sealing is the priority.
Trim Work and Wrap
Most Ashburn window projects include new interior trim, exterior aluminum coil wrap on brickmold, and foam insulation around the new frame. We do not price these as add-ons. Painted hardwood interior trim (common in historic Ashburn neighborhoods) adds $35 to $75 per window. Stained interior trim adds $60 to $120 per window.
Glass Package
Standard glass is Low-E with argon gas fill and meets ENERGY STAR for the VA climate zone. Triple-pane upgrade adds approximately $80 to $140 per window. Tempered glass (required in bathrooms and stair-adjacent openings under VA code) adds $60 to $110 per window. Obscure glass for privacy adds $35 to $75 per window.
Permits and Access
Loudoun County permit fees for window replacement run $90 to $240, depending on how many openings are being modified vs. retrofit. Standard retrofit projects on Ashburn homes are straightforward. Structural changes (combining two windows, enlarging an opening) require additional permitting and engineering review.
Windows Cost by Ashburn Neighborhood
Ashburn’s housing stock is not uniform. A 1995 estate colonial does not cost the same to re-window as a 2015 colonial, even though the curb-appeal numbers look similar. Here is what we actually see on real Ashburn jobs by neighborhood.
Belmont Country Club
Belmont estates run the largest roof footprints in Ashburn. Designer Berkshire and standing seam accents on turret features are common premium specs.
Brambleton
First-generation Brambleton roofs are now hitting their original warranty end. Builder-grade 25-year shingles are due for replacement with Owens Corning Duration.
Broadlands
Broadlands HOA approval is required on color match. We handle the HOA submission as part of every Broadlands estimate.
Loudoun Valley Estates, One Loudoun
Mix of standard architectural and designer specs. Multiple dormers and steep main gables are common.
Ashburn Village, Ashburn Farm
Original Ashburn Village roofs are on their second replacement now. Many had inadequate ridge ventilation from the original builder spec.
“Window companies are the worst offenders on inflate-and-discount pricing in the DMV. The whole industry is built on buy-three-get-one-free promotions that have a $400 discount baked into a $1,600 inflated quote. The premium brands fly a salesperson out, run a four-hour presentation, and walk you down from $34,000 to $19,000. That spread is not a deal. It is the inflate-and-discount model. We do not work that way.”
“The two questions to ask every window contractor are: is this a retrofit or a full-frame install, and is the foam insulation around the frame included or excluded. Half of the cheaper quotes in the DMV skip the foam. A window installed without foam insulation around the frame leaks air and condenses moisture into the wall cavity. That is how rot starts behind the trim. The number on the page is the number on the invoice.”
