Multi-Story Building Access: Equipment Guide for High-Rise Window Cleaning

Reach requirements by building height

Moving from residential to commercial window cleaning introduces increased floor heights, window offsets, and structural obstacles. Always calculate reach before bidding.

Standard commercial floor heights

Building Type Floor Height Typical Window Offset
Standard office 12–14 ft 3–4 ft
Retail / storefront 14–18 ft 2–3 ft
Industrial / warehouse 16–24 ft Varies
Parking structure 10–12 ft Ground level

Example reach calculation

4 stories × 13 ft = 52 ft
+ 4 ft window offset = 56 ft
+ 5 ft working margin = 61 ft minimum pole reach

Always add 5–10 feet of working margin for brush angle and control.

Pole reach quick reference

Stories Estimated Height Minimum Pole Reach
2 24–28 ft 35 ft
3 36–42 ft 50 ft
4 48–56 ft 65 ft
5 60–70 ft 80 ft
6 72–84 ft 90+ ft

Pole selection for commercial work

Pole materials comparison

Material Weight Stiffness Best Use
Carbon fiber Lightest Excellent 50+ ft commercial
Fiberglass Heavy Moderate Under 40 ft
Hybrid Medium Very good 40–60 ft

Above four stories, carbon fiber becomes essential to reduce fatigue and improve control.

Stiffness rating

Stiffness Tip Deflection
High Under 2 ft
Medium 2–4 ft
Low 4+ ft

Water delivery at height

Vertical water delivery increases friction loss. Pumps must be selected based on full-extension testing.

Up to 40 ft 0.5 GPM 12V 60 PSI
40–60 ft 0.7 GPM 12V 100 PSI
