Choose interior cleaning when the task is to remove leaves and loose debris from the gutter channel and address the visible drainage path. Choose exterior cleaning when the task is to wash visible dirt, mold, mildew, or streaking from gutter faces. One service does not automatically include the other. Ask for both only when you need both drainage maintenance and appearance work.
Service selector
| Your goal | Service to request | Confirm before booking |
|---|---|---|
| Remove leaves and channel debris | Interior gutter cleaning | Included runs, guards, downspouts, and cleanup |
| Address a likely reachable clog | Interior cleaning and visible-path check | Buried drains remain outside standard scope |
| Remove visible dirt from gutter faces | Exterior wash or gutter brightening | Method, runoff controls, and finish limitations |
| Remove mold or mildew from exterior surfaces | Exterior cleaning review | Surface suitability and treatment method |
| Fix sagging, leaks, or separated seams | Gutter repair | Cleaning is not a repair |
| Diagnose water behind the gutter | Roofer or repair provider | Roof and flashing diagnosis is separate |
Window Hero says its gutter cleaning focuses on the inside channel and excludes the outside gutter line, which it treats as part of a house wash. That is one provider's service boundary, but it is a useful example of why the quote must state interior and exterior work separately.
Use what is included in gutter cleaning to compare scope and the quote comparison worksheet to compare totals.
Limits
Exterior washing can improve appearance, but it does not prove that the channel or downspouts are clear. Interior cleaning can improve the visible drainage path, but it does not promise stain removal. Neither service repairs gutters, roofing, fascia, or buried drainage.
