Window cleaning is one of the simpler residential trades in terms of technique, but one of the more frequently under-scoped in terms of pricing. The standard quote is 'window cleaning' — a phrase that covers anywhere from just the outside of the accessible ground-floor windows to a comprehensive inside-and-out cleaning including screens, tracks, frames, and sills. The gap between these scopes is enormous, and homeowners who do not specify exactly what they want routinely end up with service that does not match expectations.
This guide is part of the Know Before You Hire series. At Home Services Co, our window cleaning service runs on disclosed scope, disclosed pricing, and complete inside-and-out service with tracks and screens included at the standard rate.
Scope breakdown. A complete residential window clean includes: exterior glass, interior glass, screen cleaning, track cleaning, sill wiping, and frame wiping. Budget operators skip most of these. When pricing quotes vary dramatically, the scope is almost always the reason. Confirm specifically which of these are included in the quoted price. Ask about second-story access (ladder work vs water-fed pole vs refusing second-story entirely).
Insurance on ladder work. Window cleaning is a ladder trade. Falls from ladders are the primary injury mode in the industry. Workers' comp matters because an injured window cleaner in your yard without coverage is potentially your liability. General liability covers damage to your property during work. See verify insurance.
Red flag #1: unwillingness to do second-story windows. Some companies only do ground-floor. That is fine if disclosed upfront, problematic if discovered on the appointment. Clarify before booking.
Red flag #2: no screens or tracks included. The quote should explicitly state whether these are included. Tracks accumulate dirt, dead insects, and pollen; unless cleaned, they spread that back onto the freshly cleaned glass the first time the window opens. A clean that excludes tracks is not a complete clean.
Red flag #3: streaking on final inspection. Proper window cleaning produces streak-free glass. If the finished glass shows visible streaks at normal viewing angles, the technique or the equipment is wrong. A professional cleaner inspects their own work and touches up before leaving.
Red flag #4: hard-water stain 'fixes' that are upsells. Hard-water mineral deposits (from irrigation over-spray or from rainwater mixing with limestone dust) bond to glass and require specific acid-based cleaners or polishing compounds. Most are not removable by standard cleaning. A cleaner who claims to 'easily remove' hard-water stains for a steep upsell may be applying a product that partially works; a cleaner who says 'this would need a separate specialty service' is being honest.
Red flag #5: pressure washers on glass. Pressure washers can damage window seals, push water into framing, and crack older single-pane glass. A professional window cleaner uses soap, water, squeegees, and microfiber — not a pressure washer. Exterior pressure washing of siding, patios, and driveways is its own separate service (see hiring pressure washing).
Pricing reality. Interior and exterior window cleaning, single-story home with 15-25 windows: $150-$350. Two-story home with 25-40 windows: $250-$550. Large home (30+ windows, complex layout): $400-$900+. Screens and tracks included: typically standard in the quoted price for professional services. Hard-water stain removal: $3-$8 per window as add-on. Post-construction clean (new construction with heavy dust and paint speckle): 1.5x-2x standard pricing. Commercial storefront: priced per pane or per visit, typically monthly recurring.
Frequency. Most residential windows benefit from professional cleaning 2-4 times per year. Spring and fall are the peak seasons. Homes near heavy pollen, near the ocean (salt spray), in construction areas (dust), or with heavy irrigation over-spray need more frequent cleaning. Interior-only maintenance between full cleanings extends the pristine look between professional visits.
Water-fed pole systems. Modern window cleaners increasingly use water-fed pole systems — carbon-fiber poles with purified water delivered through a brush head, reaching second-story windows from the ground. The purified water dries streak-free without squeegeeing. For homes where ladder access is problematic (landscaping underneath, safety concerns), water-fed poles are the correct answer. A company that can only ladder is limited in access.
Commercial window cleaning. Commercial storefronts, office buildings, and retail typically operate on monthly recurring service contracts, priced per visit based on pane count. High-rise window cleaning is a specialty discipline (rope access, swing stages) and is not part of typical residential-service companies. See our commercial services for retail and storefront accounts.
Skylights and atrium windows. Skylights are harder to clean than wall windows — interior access requires ladders over finished floors, exterior access requires working on the roof. Not all window cleaners offer skylight cleaning. Specify skylights if you have them. Additional cost is common and reasonable. A cleaner who attempts skylights without proper safety setup is a fall risk.
Storm windows, screens, and shutters. Double-hung windows with storms: the storms should be removed, cleaned, and reinstalled on the full service — many operators skip this to save time. Plantation shutters interior of windows: standard cleaning includes wiping the shutter slats; heavy dust buildup may need specialty service. Decorative leaded or stained glass: specify before booking — standard window cleaners do not clean leaded glass with the same technique.
Weather dependencies. Window cleaning in temperatures below 35°F is difficult (water freezes on the glass). Cleaning in heavy rain is pointless (rain re-spots the glass). Cleaning on windy days is difficult (wind moves the squeegee line and re-deposits debris). Most professional cleaners reschedule at their discretion on bad-weather days. Ask about the reschedule policy before booking.
Hard water staining prevention. Irrigation systems that spray water onto windows are the single largest source of hard-water stain accumulation. Redirect or shield sprinklers that hit windows. Hard-water staining progresses from removable with standard cleaning to removable only with acid or polishing, to permanently etched into the glass. Catching this early saves thousands in eventual glass replacement.
Exterior glass treatments. Some window cleaners offer glass treatments (Rain-X style or more durable professional coatings) as add-ons. These reduce water spotting and slow stain accumulation. Typical cost $1-$3 per window. They are not essential but can be worth it on homes with consistent hard-water exposure.
Scheduling and logistics. Interior window cleaning requires you to move curtains, blinds, and window treatments out of the way — or for the cleaner to do so carefully. A good cleaner will advise what to move before arrival. Expect to stay home during interior work (for access) or arrange key/access coordination.
Post-job inspection. Walk each room and each exterior area and visually confirm every window. Look for streaks, missed spots, screen dust, track debris, and sill wiping. Issues should be addressed before the cleaner leaves. Professional services touch up willingly; a problem operator gets defensive.
The summary. Confirm scope in writing (interior + exterior + screens + tracks + sills). Verify insurance. Budget market-rate pricing. Ask about second-story access method. Address hard-water issues and irrigation over-spray early. Schedule 2-4 times per year for homes that benefit from consistent appearance.
