THE WORK, EXPLAINED
Start with the condition.
Understand the scope.
Have the provider assess the existing projection and identify the proposed bay or bow assembly. Ask who will confirm its support arrangement and how the roof, sill, adjoining wall and interior seat will be addressed. Separate any supporting construction from the window supply and installation so the quote describes the complete proposed scope.
What may be involved
- bay or bow window assembly
- seat board
- head board
- support cables or brackets
- roof cap
- flashing
- 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 / Sunnyvale
Planning your work
California’s Contractors State License Board says the threshold for work requiring a contractor licence rose from $500 to $1,000, and that a project under $1,000 still needs a licensed contractor in the appropriate classification if it requires workers or permits. Confirm with the City of Sunnyvale which permits your own project needs, and check the licence before work starts. This is a statewide licensing reference, not a permit decision for your address.
