For multi unit properties and campuses, pure water Window Cleaning in Denver CO speeds exterior glass care without lifts or ladders on most levels. This guide shows how the system works, what it costs, how we plan safe access in neighborhoods like Central Park, Greenwood Village, Littleton, Highlands Ranch, and Aurora, and how to keep results bright between visits.

DI to glass how the system works

Pure water systems run tap water through DI or RO tanks until minerals are stripped away. That water reaches glass through a light telescoping pole with a soft bristle brush. The brush agitates dust on frames and panes while jets rinse soil off the surface. Because the water is mineral free, it dries spot free on interior and exterior glass without soap residue. The process also flushes frames and sills, reducing streaks that can weep after storms. Crews pair this with squeegee detailing on doors and low street level panels and can add screen cleaning, track and frame detailing, and skylight cleaning where safe.

Per pane and volume pricing for HOAs

Pricing scales with pane count, height, and layout. Long, continuous buildings in the Denver Metro areas clean faster than scattered townhomes. Upper bands that still require ladders or atrium lifts cost more. Add ons like hard water stain removal from sprinklers, decal removal, or post construction cleanup are separate line items. Route scheduling near Central Park or DTC can reduce rates when several clients share a mobilization. Ask for a photo based free estimate with pane counts by facade and frequencies for quarterly or biannual plans.

Ground access clearances and PPE

Safety starts on the ground. Crews arrive licensed and insured with safety equipment and PPE and follow OSHA ladder rules when ladders are needed for odd angles or recessed panes. We confirm electrical clearances before extending poles near service drops, and we use cones or a spotter where sidewalks and entries stay open. On campuses or retail centers near LoDo and Cherry Creek, we stage hoses to avoid tripping hazards and protect egress. DI tanks stay upright on carts with shutoff valves, and backflow protection is used at spigots. Managers can file COI and a short job hazard checklist with their records.

Scheduling large complexes without disruption

Plan by zone to keep traffic flowing. Most sites run a rotating schedule that completes exteriors in sections across one or two days. We start east and south faces early for shade and finish west faces as temps rise. Winter mornings may shift later so rinse water does not flash freeze on north exposures. Summer afternoons can gust, so we move into courtyards or lower bands when wind picks up. Entrances, leasing offices, and storefronts go first so they look fresh all day. Crews share before and after photos so boards and managers can verify progress without walking every building.

Care tips that extend the shine

Angle sprinklers so heads do not mist the glass. After irrigation repairs, flush lines to push mineral laden water away from panes. Ask landscapers to sweep or blow soil away from walls before your visit. Lightly hose lower panes with distilled or DI water after dusty wind events. Inside units, vacuum tracks during routine cleanups to prevent grit lines. Most HOAs book exterior Window Cleaning quarterly and add a spring detail that includes screens and frames.

Tools, materials, and local notes

Expect DI or RO tanks, telescoping poles, soft brushes for frames, and rinse bars for wide panes. Neutral glass solution supports door detailing. Bronze wool and guarded scrapers are reserved for approved restoration work only. In Highlands Ranch and Littleton, vinyl frames benefit from soft brushes and thorough DI rinses. In Central Park and Aurora, stucco sheds fine dust in dry spells and clears quickly with pure water. Near highways and rail, request an extra quick rinse mid season to keep lower bands from graying.
