Residential window cleaning in Las Cruces means every visible pane inside and out, plus screens off the frame and washed by hand, tracks cleaned, sills wiped, and frames detailed. What changes from town to town is not the checklist. It is what is actually on the glass. In Las Cruces, at 3,900 feet on Las Cruces Utilities' wells in the Mesilla and Jornada del Muerto basins, 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 Las Cruces. Each one is true here and false in plenty of other towns we serve.
Las Cruces is on Las Cruces Utilities' wells in the Mesilla and Jornada del Muerto basins. Desert groundwater has spent a long time in basin sediment and carries the dissolved calcium, magnesium and salts to prove it, and here it dries on glass in a climate built to evaporate it: low humidity, strong sun, and a dry season that runs most of the year. Drip lines, sprinkler heads near the house, misters on a patio, a hose rinse left to air-dry, and a roof cooler's bleed water all leave mineral behind, and in this sun it bonds within days rather than sitting loose on the surface. Caught in its first season it washes off with the right chemistry. Left for a few summers it becomes etching, and etching is in the glass, not on it.
The first is the spring wind. From roughly February into May, and hardest in March and April, sustained west winds lift sand and silt off open desert and drive it into every track, weep hole and screen on the windward side of a Las Cruces house. That grit is the reason tracks get cleared dry before any water touches the glass: wet a track full of desert sand and drag a squeegee through it and you are sanding the pane. The second is the monsoon. From July into September, thunderstorm outflow can push a wall of dust ahead of the rain, and then the rain lands on glass that was just dusted, leaving a mud-spotted film that looks worse than before it rained. The visits that do the most good here land after each season closes, not in the middle of either.
Pecan groves line the river valley around Las Cruces, and they put two things on a house nearby. In spring the trees release catkin pollen that films glass and packs into screen mesh. In late fall and winter, harvest crews shake the trees and sweep the orchard floor, and for weeks at a time that puts fine orchard dust in the air on days with no wind at all. Flood irrigation between those seasons keeps the valley floor cycling between damp and dusty. Homeowners who time cleaning to the weather alone keep getting surprised, because the dust here does not wait for weather. A visit after harvest wraps up, and another after the spring wind, is what keeps valley glass looking right.
Evaporative cooling is common in Las Cruces, 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.
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, priced per window so you can decide.
Sills (the inside ledge) and tracks (the bottom channel where the window slides) are cleaned out 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.

Older brick and block homes and rentals near NMSU, many with rooftop coolers and the white streaks that come with them.
One of the oldest parts of town, with adobe homes and old glass that gets careful hand cleaning.
Historic homes from the railroad era with original windows. We check the putty before we put any pressure on old glass.
Valley neighborhoods near fields and pecan orchards, where harvest dust and sprinkler spotting both show up.
Open, higher ground east of I-25 with wide views of the Organs and nothing to break the spring wind. Sand in tracks and screens is the first job.
Newer homes with large view windows toward the Organ Mountains. Those panes are usually the reason people book.

Las Cruces is in the Chihuahuan Desert, served by Sonlight's El Paso-based crew since October 2026. Glass here deals with two dust seasons (the spring wind, February into May, and the July to September monsoon), hard groundwater that dries fast in strong sun, and evaporative coolers on much of the older housing.
The order of work matters more here than almost anywhere: tracks, weep holes and screens are cleared of desert sand dry, first, and only then does water touch the glass. Wet sand under a squeegee scratches a pane. In summer, exterior glass is worked on the shaded sides first so nothing flash-dries into fresh spots in the sun.
Three times a year is the honest answer for most of Las Cruces, 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.
Both, included. Screens come off the frame and are washed flat rather than brushed in place, and tracks are cleared dry before any water goes on the window. That dry-first step matters more in Las Cruces than in most markets, because wind here loads tracks with sharp grit and wetting it before removing it is how glass gets scratched.
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.
We monitor weather closely. If conditions are unsafe, we'll reschedule for the next available slot (usually within 2-4 days) at no charge. We always give at least 24 hours' notice on weather-related reschedules.
