A closer look
Frames, drainage, seals and surrounding trim help explain what an opening needs.


Start locally
Find the service for your opening and confirm address coverage when you call.
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.
Before you decide
A sticking panel can involve rollers, track damage, alignment or worn seals. Ask which condition was observed and whether compatible parts are available. A sound frame may remain in place for a targeted repair; deterioration at the sill or frame can change that scope. Compare the actual findings before choosing a complete replacement.
Moisture between the panes is different from condensation on a room-facing surface. A proposal may replace the sealed glass unit while retaining a suitable sash and frame. Ask which component has failed, how the replacement glass is specified and whether the existing frame can support the work.
An insert retains a suitable existing frame and places a replacement unit within it. Full-frame work removes more of the assembly and exposes the opening for assessment. Compare retained materials, flashing work, trim restoration and the resulting clear opening rather than treating both proposals as the same job.
Compare the ratings for the complete product and its suitability for the local climate and project. U-factor and solar heat gain coefficient describe different aspects of performance. Ask which specified unit the label describes; a generic brochure does not establish the rating of the product being supplied.
Describe the opening, how it moves and what changed. Note whether a concern is with glass, the moving panel, hardware or the surrounding wall. If available, gather product labels, earlier invoices and photographs taken without dismantling the assembly. Explain access restrictions and keep people away from broken glass.
Ask which units and components are included, what remains in place, how access and removal are handled, and who restores affected finishes. Confirm product specifications, disposal, weatherproofing and completion checks. Any concealed damage discovered during the work needs an explained change to the agreed scope.
