Residential window cleaning in Littleton means every visible pane inside and out, plus screens off the frame and washed by hand, tracks vacuumed, sills wiped, and frames detailed. What changes from town to town is not the checklist — it is what is actually on the glass. In Littleton, at 5,351 feet on Denver Water and the South Platte supply serving the Littleton districts, the work is shaped by airborne debris more than anything else, and the sections below explain exactly how.
Quick answer
Residential window cleaning means a full clean of every visible window, inside and out, including screens, sills, and frames.
The checklist is the same everywhere. What is on your glass is not. These are the conditions that actually shape this job in Littleton — each one is true here and false in plenty of other towns we serve.
Cottonwoods along the river corridor near Littleton release seed cotton in late May and June in volumes that surprise anyone who has not lived through it. It mats into screen mesh, packs weep holes and window tracks, and clings to any glass with residual moisture. No product removes it — it is fiber, and it has to be physically lifted out. The common mistake is brushing screens in place, which felts the cotton deeper into the mesh and leaves the screen worse than before. Screens have to come off the frame. Scheduling matters too: a clean in mid-June gets undone within a week, so early July is the appointment that actually holds.
Littleton's older housing stock includes original wood sash with hand-set glazing, and in the oldest homes the putty failed decades ago and was painted over — meaning the glass is held in place substantially by paint. Cleaning that aggressively can dislodge a pane. We check first, work gently, and tell you what we find, because discovering a glazing failure with a squeegee is the expensive way to learn about it.
The Front Range is one of the most hail-prone corridors in the country, and Littleton sits in it. Screens are the first casualty: mesh tears, splines pop out of the channel, and frames bow. Homeowners frequently discover the damage only when a cleaner removes the screens, because from inside a bowed screen looks fine. We inspect every screen we take off and tell you what we find, with re-screening priced per window so you can decide rather than being surprised. Hail also drives grit into gutters and dents downspouts in ways that show up as drainage problems months later.
Every visible window in the home — interior and exterior surfaces, plus screens, sills, and frames. We don't skip the kitchen window above the sink, the basement egress, or the garage windows.
Screens are removed, washed by hand, and reinstalled. Bent screen splines are corrected; severely damaged screens are flagged for our optional re-screening service ($25–$45 per window).
Sills (the inside ledge) and tracks (the bottom channel where the window slides) are vacuumed clean of dirt, dead bugs, and dust. This is the part that DIY cleaning almost always misses.
Frames are wiped down — the painted or wooden border around the glass — including the corners where mineral deposits and pollen accumulate.
Pre-walk and final-walk: a Sonlight technician walks the home with you (if present) at the start to flag anything unusual, and again at the end to verify the work meets your standard.
Enter your address. Our autoquoter pulls property details from public records and returns a real, firm price in seconds. No callback, no in-home estimate.

Our crew shows up within the time window, in branded trucks with $2M liability and workers' comp. The lead tech walks the property with you (if home) before starting.
Interior windows are squeegeed dry with hand-towels and finished by hand. Exterior is cleaned with a purified-water rinse system that prevents new mineral spotting.
We walk the home with you (or send photos if you're not there). Pay by card, ACH, or check. If anything looks off within 24 hours, we come back free.
Most Littleton properties land between $310 and $495 for this service. That band is derived from real Littleton jobs, not a national average — which is why it differs from the number you would see on our page for a neighboring town. Here is how the job profiles break down:

Colorado's mile-high+ altitude means UV exposure is 25-40% stronger than at sea level. Mineral deposits etch into window glass faster, and window seals fail sooner. Twice-yearly professional cleaning is the practical baseline — quarterly for west-facing exposures or homes near sprinkler overspray.
Front Range water averages 50–150 ppm hardness depending on city (Denver Water ~70 ppm, Colorado Springs Utilities ~125 ppm). The water is also slightly alkaline (pH ~8) which etches the silica in glass faster than acidic water of the same hardness.
Spring pollen (cottonwood, pine) and June cottonwood fluff are the heaviest contamination periods. Most Front Range homeowners book a major clean in late May or early June after pollen drops, then a second in October before the holidays.
Twice a year covers most Littleton homes. Spring after pollen drops and fall before the first hard freeze are the two appointments that do the most work. If you are near the cottonwoods, push the first visit to early July — a clean in June gets undone by cotton within a week.
Both, included. Screens come off the frame and are washed flat rather than brushed in place, and tracks are vacuumed dry before any water goes on the window.
Most 2-story Colorado homes (1,800–2,400 sqft, ~22–30 windows) take 2–3 hours with a 2-tech crew. Larger custom homes can run 4–6 hours. We'll give you a specific time window when we confirm the booking.
No. As long as we can access exterior gates, side yards, and any rooms you want cleaned interior, we're fine. We text you when the crew arrives and when the job is complete with photos. Most of our recurring customers are not home during the appointment.
Full service = interior + exterior + screens + sills + frames. Exterior-only = exterior surfaces only, no interior access required. Exterior-only runs about 65-75% of the full-service price and is faster to schedule. Most customers do full service in spring and exterior-only in fall.
Yes. We use water-fed pole systems that reach up to 4 stories, and rope-descent gear for taller buildings. There's no upcharge for height on a typical 2-story residential job — height pricing only kicks in for homes over 3 stories or with bosun-chair access requirements.
