If you are thinking about a cottage rewire this summer and you have not booked it yet, May is the month the calendar tells the truth. The crews that do this work are already half-committed to projects that were quoted in February and March, and by the time June arrives the available windows are short, awkward, and starting to push into July. Here is how the summer cottage rewire schedule actually fills — and what we can still do for you if you are starting the conversation this week.
Why summer is the only window for most rewires
A cottage rewire is dust, noise, and the cottage being out of service for the duration. None of that is compatible with the cottage being occupied. The only window that works for most owners is the one when the property is empty and accessible — which on a four-season cottage means the shoulder seasons, and on a three-season cottage means the same. For most Muskoka owners that translates to May, early June, late August, September, and October. The peak summer weeks of July and the first three weeks of August are off-limits because that is when the owners are using the cottage.
So the available work weeks are roughly 16 to 20 per year, and they are split across every cottage owner in the region who is doing electrical work that needs the property empty. The crews that do this work, including ours, have a fixed capacity, and that capacity is a real constraint. By the time you read this post in May, the prime spring weeks are mostly booked.
The booking timeline that actually works
- February or March — quote and design. Walk the property, scope the rewire, decide whether it is whole-house, partial, or phased. Sign the quote, commit to the timeline.
- March or April — ESA permit pulled, parts ordered. Panel, wire, devices, fixtures. Lead times on some panels have been running 4-6 weeks in recent years, so ordering early matters.
- May or June — work happens. Cottage empty, crew on site, ESA rough-in inspection partway through, final inspection at the end.
- Long weekend in May or June — cottage back online. Owner walks through, signs off, season starts.
The customers who get squeezed are the ones who started thinking about it in late April. Not impossible to schedule — but the choices narrow, the cost can go up because the crew has to fit it in around other commitments, and the parts supply chain may push out a week or two.
Parts availability: the part nobody talks about
Panel availability has been the bottleneck in the past couple of seasons. Siemens, Eaton, and Schneider load centres in the 200A residential range are usually in stock locally, but specific panel configurations (anything with combination AFCI/GFCI breaker complements pre-loaded, or non-standard knockout patterns) can run 4-6 weeks. Service-entrance cable in larger sizes, meter bases, and surge protective devices have all had supply hiccups in recent years.
Our approach: we order long-lead items as soon as the quote is signed, even if the install is two months out. The deposit on the parts goes into our supplier account; the parts come to us; we store them until install week. The customer pays a small percentage holding cost in exchange for not having the project paused waiting for a panel that did not arrive on time.
ESA inspection scheduling: not infinite either
ESA inspectors are real people with real calendars, and they are busiest in the same months we are. A rough-in inspection scheduled the day after we finish rough-in is the ideal; an inspection that has to be scheduled five days out because the inspector is fully booked is the reality on peak weeks.
The practical implication: we schedule the ESA inspection at the time we pull the permit, not at the moment we are ready. The inspector knows our finish dates and books accordingly. Rewires that get the ESA timing wrong end up with the property energized late because the inspection slipped — and at that point the owner is missing a weekend they wanted to be at the cottage.
Whole-house vs. partial vs. phased
The decision about scope is the largest one in the budget. We covered the basics in our knob-and-tube remediation post — the same logic applies to general cottage rewires.
- Whole-house rewire takes 5-10 working days on most cottages depending on size, finished-wall complexity, and how much drywall repair follows. Cleanest outcome, longest disruption.
- Partial rewire targets the rooms or circuits that need it most (typically the kitchen and primary suite) and leaves modern wiring intact. 3-5 working days. Good for cottages where parts of the building were already updated.
- Phased rewire splits the work across multiple shoulder seasons. Year one: kitchen, baths, and primary panel upgrade. Year two: bedrooms and basement. Year three: outbuildings and dock. Lets the budget spread and lets the work fit smaller windows.
Most of the cottages we phase are ones where the budget for a single-summer whole-house rewire was a stretch, but a yearly investment is comfortable. The math works out roughly the same in total (slightly more because of the per-mobilization overhead) but the per-year hit is manageable.
What pairs with the rewire
If we are already on site with the cottage open and the walls exposed, the marginal cost of pairing other work is significantly lower than doing it as separate jobs.
- Service upgrade. If the panel is being replaced anyway, going from 60A or 100A to 200A is much cheaper as part of the same job than as a separate visit.
- EV charger conduit. Pull a conduit run from the panel to the driveway or boathouse parking spot, even if you are not buying the car this year. Saves the eventual install from being a wall-fishing exercise.
- Generator transfer switch. If a standby generator is in the plans, getting the transfer switch in place during the rewire eliminates a future panel swap headache.
- Smoke and CO interconnect. Whole-house interconnect on new wiring is dramatically cheaper than retrofit interconnect after the fact.
- Smart-home backbone. Cat6 to every room, conduit sleeves to future locations, neutral conductors at switch locations for smart switches.
- Dock and outbuilding feeds. If the dock or boathouse needs work, schedule it as part of the same crew week.
If you are reading this in May with no booking yet
Call us this week. The options that are still real, in rough order of likelihood:
- Phased start this summer. Book a 2-3 day window for the critical work (panel upgrade, kitchen rewire) and phase the rest into September.
- September booking. The post-Labour-Day weeks open back up. Cottage empty after the long-weekend, weather still cooperative, ESA workload eases.
- Cancellation list. Projects do cancel and slip. Getting your name on the list with a signed quote and a deposit means the next opening that fits your scope comes to you first.
What does not work: waiting until July to think about it and hoping for an August window. The August windows are taken in February.
When to call us
If you are planning a cottage rewire in Huntsville, Bracebridge, Gravenhurst, Port Carling, or Baysville, request a rewire quote as soon as you know you want the work done. We walk the cottage, scope the work, identify whether it pairs with a service upgrade, and quote in writing. We will tell you when the next available window is and what we can still fit in.
