Professional installers have a short season and a fixed number of crews, so the calendar is the real constraint. The earlier you ask, the more choice you get on install date, design and, sometimes, price.
The short answer: ask in September or October
Many installers start booking in late summer, and returning customers and commercial clients often take the first dates. If you want lights on by the Thanksgiving weekend, request a quote in September or October. A November request can still work, but expect fewer install dates to choose from.
A typical Bay Area season
| When | What usually happens |
|---|---|
| August–September | Installers open bookings; returning customers rebook |
| October | Designs and quotes; commercial installs begin |
| Early–mid November | Most residential installs; lights tested, timers set |
| Thanksgiving weekend | The traditional lights-on date for many homes |
| December | Service calls for any dark sections; late installs if dates remain |
| January | Takedown and storage |
Installing in early November doesn't mean the lights have to be on. Most installs include a timer, so they can stay off until whatever date you choose.
No snow, but rain matters
Walnut Creek doesn't get snow, which makes installation easier than in colder places, but wet roofs and wind can push dates back. Booking early leaves room for a weather delay without missing the date you care about.
Left it late?
- Call rather than email. It's the fastest way to find out whether a date is still open.
- Keep the design simple. A roofline-only install fits into a full schedule more easily than a large custom design.
- Be flexible on the date. A weekday install is often easier to fit in than a weekend.
- Plan next year now. If this season is full, ask to be put on the list for next year, or look at permanent lights, which can be installed outside the rush.
When do lights come down?
Usually in January. If you want them up for longer, or you have an HOA or landlord deadline, agree the takedown date in writing when you book.
