The short answer
Seven variables set most exterior services pricing: how much there is to do, how hard it is to reach, what condition it is in, how often it is done, what compliance has to be in place first, when it is scheduled, and how many buildings are in the program.
The seven cost drivers
- Scope size. Panes of glass, square feet of surface, linear feet of gutter or acres of lot set the core size of the job.
- Height and access. Ground-level work goes fast. Lifts, rope access and staging change the labor per unit.
- Surface condition. Heavy buildup, hard-water staining, tinted or coated glass, mold and algae take more care and time.
- Frequency. Recurring programs price lower per visit than one-time work, because regular service keeps surfaces from building up.
- Compliance prerequisites. Roof anchors must be inspected and certified before rope descent work can start.
- Season. Summer is peak season for high-rise and rope-access work.
- Portfolio scale. One contract across many buildings simplifies scheduling, standards and invoicing.
Cost drivers by service
| Service | What moves the price most |
|---|---|
| Window cleaning | Height and access, glass count, exterior only or inside and out, glass condition, frequency |
| Pressure and soft washing | Surface area, surface type, level of buildup or growth, height |
| Glass and metal restoration | Extent of damage, number of panes or fixtures, access |
| Gutter cleaning | Length of gutter, height, debris load |
| Parking lot sweeping | Lot size and frequency |
| Anchor inspection and certification | Number of anchors, testing method, repairs found |
Where low bids usually cut
When a bid is far below the others, check what is missing: insurance, training, safety planning, or W2 crews replaced with subcontractors. At height, those gaps become the property's liability. See how to compare exterior services bids.
How to get an accurate number
- For window cleaning, get a ballpark in 30 seconds with the pricing calculator.
- For a quote, a walkthrough: S&K assesses the property, scopes the work and delivers a clear, fixed proposal.
- For a whole program, list every service and cadence first. See how to build an annual exterior maintenance calendar.
