Residential window cleaning in Los Lunas 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 Los Lunas, at 4,852 feet on the Village of Los Lunas' wells in the Rio Grande valley aquifer, the work is shaped by mineral load 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 Los Lunas — each one is true here and false in plenty of other towns we serve.
Los Lunas draws from the Village of Los Lunas' wells in the Rio Grande valley aquifer. Groundwater carries substantially more dissolved calcium and magnesium than a snowmelt supply, so every sprinkler pass, hose rinse, or cooler bleed that lands on glass leaves mineral behind when it evaporates. Homeowners who moved here from a soft-water Front Range city are routinely surprised how fast spotting appears — the house did not change, the water did.
Evaporative cooling is near-universal in Los Lunas, and most units sit on the roof. From April through October a cooler discharges mineral-saturated water on purpose — that is how it keeps salts from concentrating in the pan — and that water runs down the roof and across whatever windows are underneath. It evaporates in the sun and leaves calcium and magnesium carbonate in vertical streaks. Homeowners almost always blame the last window cleaner. It is not soap residue and washing will not remove it; it needs mineral restoration, and then the bleed line needs rerouting so next summer does not undo the work.
Cottonwoods along the river corridor near Los Lunas 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.
Older Los Lunas construction is adobe with lime-plastered reveals and, in the oldest stock, original glass that cannot be replaced. Pressure washers, water-fed poles, and alkaline chemistry all damage lime plaster, and aggressive cleaning can dislodge panes held in place by failed putty and a century of paint. Those buildings get hand cleaning with chemistry kept off the plaster entirely, and if the glazing has failed we report it rather than working past it.
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.
Choose any open day on our calendar in the next 14 days. Same-day booking cuts off at 6 PM the prior evening. SMS + email confirmation arrives instantly.
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 Los Lunas properties land between $355 and $560 for this service. That band is derived from real Los Lunas 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:

Historic railroad town south along the river with an older adobe core, flat roofs, and canales.
Commercial and industrial glass along the interstate, with bare-ground dust from ongoing development.
Established subdivision on former ranch ground with mature landscaping and heavy irrigation on hard water — spotting is the leading complaint.
Newer production housing with two-story gable-end glass; ongoing build-out nearby keeps construction fines in play.
Closer to the bosque, with real June cotton and autumn leaf load in gutters and weep holes.
East-side lots rising toward the mesa with more wind exposure and less bosque debris.

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.
Three times a year is the honest answer for most of Los Lunas, not twice. Schedule around the actual local calendar: late April after wind season, and late September after the monsoon closes out. Add a mid-summer visit if you run a roof-mounted evaporative cooler. 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.
