Window Cleaning in Ashburn, Virginia
Every job starts with a walk of the property to identify hard-water spotting on ground-floor and walkout-level glass, sap accumulation under tree canopy in mature communities like Ashburn Village and the Courts and Ridges, and screen condition that traps pollen against the mesh long after the yellow haze has settled elsewhere.
The Short Answer
Most Ashburn exterior window cleanings run $8–$15 per window — screens, sills, and tracks included, not extra. Pure-water (deionized) technology scrubs the glass and rinses to a spot-free dry with no detergent haze, and second or third stories are reached safely from the ground by water-fed pole.

Areas We Serve
Window Cleaning — Areas We Serve in Ashburn
The most common mistake we see in Ashburn is homeowners waiting until windows look bad to call anyone — by then, hard-water spots have often had weeks of sun exposure to bake onto the glass, and tree sap has cured into a sticky lacquer that a simple wipe-down won't budge. Loudoun's water, whether from a private well pulling through the region's limestone and chalk strata or from the treated municipal supply, carries enough calcium and magnesium that spotting is close to guaranteed on any south- or west-facing exposure that catches sprinkler overspray or rain runoff. Add in the county's heavy spring pollen load and the sap drop from the mature tree canopy found throughout established neighborhoods, and exterior glass in Ashburn accumulates layered residue faster than most single-pass cleanings can fully lift. Lawn Theory provides professional window cleaning throughout Ashburn — every neighborhood below and beyond.

Ashburn, Answered
Window Cleaning in Ashburn — Common Questions
How often do Ashburn homes really need exterior window cleaning?
Most Ashburn properties do well with two cleanings a year, timed around the two biggest offenders: the spring pollen surge and the summer/fall tree sap drop common in tree-lined communities like Ashburn Farm and Broadlands. Homes with heavy well-water irrigation or sprinkler overspray on ground-floor glass sometimes need a mid-season hard-water touch-up as well.
Why do my windows keep getting spotty even after I rinse them myself?
That's Loudoun County's water hardness at work. Whether your home is on a private well pulling through the region's limestone and chalk-derived groundwater or on treated municipal supply, the calcium and magnesium content is high enough that plain water evaporates and leaves mineral deposits behind. A hose rinse just spreads that residue around instead of removing it \— it takes a proper hard-water treatment pass to actually lift it.
Do you clean window tracks and screens or just the glass?
Both, every time. We flush and detail tracks where pollen and grit compact into a grinding paste, and we pull, rinse, and reset screens so they're not acting as a pollen filter pressed against your glass. Treating glass, track, and screen as one job is the only way the result actually holds.
Can you handle tree sap without damaging the glass or window frames?
Yes. Sap from the mature oak and pine canopy found throughout established Ashburn neighborhoods needs a controlled approach, not scraping or harsh solvents that can haze glass or degrade frame seals. We use methods that break down sap safely so it lifts clean without marking the surface underneath.
Is this safe for newer high-efficiency or tinted windows in communities like One Loudoun or Brambleton?
Yes. We adjust our approach for the glass and frame type in front of us, including low-E coatings and tinted panels common in newer builds around One Loudoun and Brambleton, so the cleaning process doesn't compromise coatings or seals. Our crews work Ashburn regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
