After-hours commercial installs, sequenced to your operations.
Overnight and weekend commercial install scheduling isn't just 'do the work at night.' Sequencing, crew staffing, and operational integration determine project success.

Commercial electrical installs typically happen overnight (10pm-6am) or full weekend windows. Sequencing matters: identify critical loads that must stay energized throughout, plan cutover sequence to minimize the actual power-off window, stage equipment so installation completes within the planned window, schedule inspector for first-thing-Monday after weekend install. Premium for after-hours work: typically 25-50% over standard daytime rates, offset by operational continuity value.
01Three approaches to after-hours commercial work.
Single overnight window: typical for smaller panel upgrades, sub-panel additions, equipment circuit work. Crew arrives 10pm Friday or selected weekday, works through the night, restores power by 5-6am, business opens normally. Works for scope completable in 6-10 hours of focused work. Common for Marin restaurant and retail panel work.
Multi-night weekend: typical for larger service upgrades, voltage class changes, or scope requiring inspector visit during work. Crew Friday night 10pm through Sunday afternoon, with inspector visit Saturday or Sunday. Business reopens Monday with completed work. Common for office building panel upgrades, larger restaurant TI completion, retail location service work.
02How we sequence the actual work.
Critical loads stay energized
Refrigeration, server rooms, security systems, life safety — identified in pre-install walkthrough and either temporary-powered (generator or transfer) or sequenced last in the cutover so they're only off briefly. We verify with business operations which loads can tolerate the planned shutdown window.
Cutover sequence planned in advance
For service upgrade: existing service disconnected, new service energized, branch circuit cutover from old panel to new panel in planned sequence. Each circuit identified, labeled, and migrated systematically. Pre-planned sequence prevents confusion during the live work and minimizes total power-off time.
Equipment staged and pre-positioned
Day-of install isn't the time to receive deliveries. New panel, breakers, conductors, terminations all delivered and pre-positioned at site before install night. Crew arrives ready to work, not waiting for materials. Reduces install window length materially.
03Why after-hours premium is worth paying.
The 25-50% labor premium for after-hours work covers crew overtime and disruption to crew personal schedules. The business value of operational continuity during business hours typically far exceeds this premium. A restaurant losing one day of revenue often equals $4,000-$12,000+; the premium for after-hours install is usually $500-$2,000 over daytime cost. Math favors after-hours work for any operation where business hours matter.
We staff a dedicated after-hours crew for commercial work — same electricians who handle daytime residential work, available for evening/overnight/weekend commercial scheduling. Continuity of personnel matters: the team that quotes the work executes the work; no handoff to unfamiliar contractors. For Marin commercial customers, this consistency improves project outcomes meaningfully.
Common questions.
How much does after-hours premium add?
Typically 25-50% over standard daytime rates. For a $12,000 daytime panel upgrade, after-hours version runs $15,000-$18,000. The premium covers crew overtime, disruption to personal schedules, and additional planning overhead. Most commercial customers find the operational continuity value justifies the premium easily; in some cases the project couldn't proceed at all during daytime hours due to business operations.
Can the inspector visit overnight?
Marin AHJ inspectors typically schedule daytime visits, not overnight. For overnight installs that need inspection before re-energization, we schedule inspector for first thing the next business day (Saturday or Monday depending on install timing). The work-completion-to-inspection gap is typically 8-16 hours; we coordinate timing to minimize.
What if work takes longer than planned?
Pre-install planning sizes the work to fit confidently within the planned window. We add ~25% buffer to expected work time when defining the install window. If unexpected complications extend work beyond window, options: complete what's safe to complete and resume next available window, or extend the window with crew and business agreement. Rare to need extension when planning is thorough.
Do you work major holidays?
Yes for commercial customers — we operate emergency dispatch and have done major holiday work for restaurants, retail, and healthcare facilities. Holiday premium adds another 25-50% over standard after-hours premium. Most commercial customers schedule major work for normal weekend windows rather than holidays unless operational necessity drives timing.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
Are you licensed and insured?
Yes. California State License Board C-10 Electrical Contractor #989290, in good standing. Carry general liability insurance and workers' compensation insurance as required by California law. Bondable on projects requiring it. Happy to provide proof of insurance to clients or property managers on request. License lookup: cslb.ca.gov.
Emergency response across Marin County.
Same-day dispatch for safety scenarios. Typical on-site time 1-3 hours weekday, 1-4 hours after-hours.
