Exterior window cleaning in Fairfax County typically costs 0 to 0, with per-window pricing of to based on size, accessibility, and hard water mineral source and extent. Smaller homes start at 0. Average two-story colonials in Burke, Springfield, Centreville, and Reston are 0. Larger homes in McLean, Great Falls, and Oakton with many windows and potential dual-source mineral staining from private well groundwater are 0. The per-window rate applies to large-format or upper-story windows and to windows with significant groundwater iron oxide staining requiring dual-mineral treatment in addition to standard calcium dissolution.

Most Fairfax County homes benefit from exterior window cleaning once or twice per year \— spring and fall. Properties near the Tysons redevelopment corridor in Tysons, McLean, Vienna, Falls Church, Pimmit Hills, and Merrifield \— where sustained urban construction dust from the ongoing redevelopment project accumulates continuously \— may benefit from more frequent cleaning during the most active construction phases. Properties with private wells drawing on Fairfax County's iron-rich groundwater may also need more frequent cleaning if irrigation or other water contact with windows produces rapid iron oxide staining re-accumulation between professional cleanings.

Yes. Screen removal, cleaning, and reinstallation is included in every exterior window cleaning service. Screens are carefully removed, cleaned to remove dust, pollen, and Tysons-corridor construction dust where applicable, and reinstalled after glass cleaning is complete. Window frames, sills, and tracks are also cleaned of debris and mineral buildup \— including the iron-stained mineral scaling on window sill surfaces from groundwater-source hard water that is distinctive to Fairfax County's older established neighborhoods and private well properties.

Yes \— and Fairfax County's hard water stains are more complex than standard irrigation-only deposits found in newer planned communities. Fairfax County's hard water challenge has two sources. Irrigation-system calcium and magnesium scaling \— the white cloudy deposits common on lower-story windows adjacent to landscaping \— are addressed with standard acid-free calcium mineral dissolution treatment. But properties drawing on Fairfax County's iron-rich groundwater through private wells or older county supply connections may also show iron oxide staining \— a reddish or brownish discoloration on glass and frames that requires a different mineral treatment targeting iron compounds in addition to calcium. During the window assessment step, Lawn Theory identifies the mineral deposit type on each window and selects the appropriate treatment \— standard calcium treatment, iron-specific treatment, or a combined approach where both mineral types are present.

Yes. Water-fed pure water pole systems clean second and third story windows from the ground without ladder access \— eliminating the fall risk of DIY upper-story cleaning. The system delivers de-ionized pure water through a brush head that loosens soiling, followed by a pure water rinse that dries streak-free with no mineral residue. For Fairfax County's large estate homes in McLean, Great Falls, and Oakton with three-story heights and premium window installations, professional pole systems are the only approach that achieves true streak-free clarity on upper-story glass without the surface risk of direct ladder-pressure contact on expensive window frames.

No. Professional squeegee technique removes all cleaning solution and soiling without residue. Water-fed pure water pole systems use de-ionized water that contains zero dissolved minerals \— it dries with no streak marks because there is nothing left in the water to deposit on the glass. In Fairfax County, DIY window cleaning streaking is often compounded by the county's elevated groundwater mineral content in tap water \— using mineral-laden tap water for DIY window cleaning leaves both the soiling residue and the minerals from the cleaning water itself on the glass. Professional de-ionized pure water eliminates this entirely.

Water filtered to near-zero dissolved solids scrubs the glass via a soft-bristle pole brush, then rinses clean and dries without spots — no squeegee marks, no detergent film, and no ladders leaned against your siding. Because nothing dries onto the glass, results hold visibly longer than squeegee work — typically months of clarity even through pollen season's tail.
