THE WORK, EXPLAINED
Start with the condition.
Understand the scope.
Ask for the opening assessment, selected window and any proposed opening changes to be identified separately. Have the provider explain who will confirm the project-specific requirements and how the completed opening will be checked against them. Include surrounding construction and finishing responsibilities in the proposal; a service-page description does not establish compliance for a room.
What may be involved
- window sized for the required clear opening
- header and framing lumber when required
- sill pan
- flashing
- fasteners
- insulation
- trim
Ask the provider to distinguish existing parts to inspect, proposed replacements, and tools, materials or reports included in the service. Confirm the work and exclusions after assessment; this list does not mean that every item will be supplied or replaced.
LOCAL RESEARCH / Belmont
Building history
Belmont incorporated in 1927 in the Peninsula's early-twentieth-century suburban expansion.
Source ↗Local context
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 ↗Planning your work
In San Mateo County's incorporated cities the building department for the city that covers the address is the permitting authority, not the county. The Contractors State License Board's consumer page on building permits states the California Building Standards Code position that work may not be erected, altered, repaired or demolished without a permit first obtained from the building official, notes that code requirements vary between cities and counties, and asks readers to check with their local building department. Confirm the scope with that department before work is arranged.

Before the visit
Identify the affected opening and describe the symptom. Gather available product labels and previous work records. Explain access restrictions and keep the opening clear.
