The short answer
Scope creep comes from what the contract does not say. Write in quantities per building, inclusions and exclusions, a price list for add-ons, how first-time or heavy-condition work is handled, access assumptions, and a written change process with unit prices.
Where scope creep comes from
- "All windows" with no count, sides or elevations
- Inside vs. outside left unstated
- Screens, tracks and frames assumed by one side and not the other
- A first clean on heavy buildup priced as a routine visit
- Access that changes once the crew is on site
- Extra visits or re-cleans with no agreed price
- New buildings added mid-contract with no rate
How to write it out
| Clause | What to write |
|---|---|
| Quantities | Panes, square feet or linear feet per building and elevation |
| Inclusions and exclusions | A named list of both |
| Add-on price list | Unit prices for screens, tracks, hard-water removal, first-time cleans |
| Condition clause | First-time or heavy-buildup work priced separately from routine visits |
| Access assumptions | The access method per elevation, and what happens if it changes |
| Change process | Written approval before extra work, at the contract's unit prices |
| Quality process | How missed areas are reported and resolved |
| Adding buildings | New locations at contract unit rates |
It protects both sides
Clear scope protects the owner from surprise invoices and the vendor from unpaid work. It also makes renewals easy to price. See what a window cleaning scope of work must specify.
How S&K scopes
S&K walks the property, scopes the work and delivers a clear, fixed proposal before the first visit.
