The symptom
One window is cracked, leaking, or impossible to use while the rest of the house is still fine.
The proposed method
Identify the one opening and the reason for replacement. Ask whether the proposal retains the existing frame or removes the complete unit, how the new window will match adjacent openings, and which trim and finishes are included. Have any work outside that opening identified separately instead of assuming the surrounding construction will be unaffected.
Items to discuss
replacement window, flashing or frame adapter, fasteners, insulation, sealant, matching trim. Clarify which parts or materials would be supplied, which tools would be used, and what documentation is included.
Property context in Outer Richmond
Planning identifies this area among neighborhoods containing RH-1 one-family residential zoning, so individual-home hardware is part of the local mix.
Source for housing context ↗San Francisco's Department of Building Inspection publishes step-by-step instructions for over-the-counter permits covering doors, windows, reroofing and other common exterior residential projects. The page lists in-kind window replacement and in-kind exterior door replacement, at the same size and location, among the projects eligible for over-the-counter review through the PermitSF portal, and separately says that new windows or exterior doors in new locations are among the projects that need plans. Read it before agreeing a scope, and confirm the address, the opening and the review route with the department. It does not decide eligibility, timing or requirements for an individual property.
Source for planning your work ↗California licenses contractors by classification, and the Contractors State License Board publishes the current list. Glazing work sits under C-17 Glazing Contractor, so it is reasonable to ask which classification a licence carries and to check the licence number with the board before glass or window work is arranged. The classification list describes the trades the state recognises; it is not a record of any particular company's licence, standing or suitability for your project.
Source for local context ↗Area-wide context is not a finding about your own property.
What shapes the quote?
The component being changed
Glass-only, hardware-only and complete-frame work involve different materials and labor. Compare proposals for the same work.

Opening size, access, finishes and damage discovered during removal can change the work. Agree how any change will be documented.
The complete proposal
Clarify removal, disposal, weatherproofing, finish restoration and completion checks before comparing totals.
Ask for a written quote and confirm the complete charge before work begins.
Before the visit
A little preparation helps.
