Correctly sized units with automatic transfer switches (ATS) for seamless power during outages. - Portable/backup setups:
Inlet, interlock or transfer switch installs so you can safely power essentials without backfeeding. - Panel and service upgrades:

Our process is simple: we perform a load assessment, explain options (whole‑home vs. essentials), and give you a firm written quote before any work begins. On install day, our crew follows Lockout/Tagout, avoids live work unless it’s absolutely necessary, and labels everything for easy future service.

Which Backup Power Setup Is Right for You?
There are three main ways to safely connect a generator to your home. We'll help you choose based on your budget, what you need to run, and whether someone will be home during an outage.
Generator Interlock Kit + Power Inlet
Best for: homeowners with a portable generator who want the lowest-cost safe setup. We mount an interlock on your existing panel and install an outdoor power inlet. During an outage, you roll the generator out, plug it in, and turn on the circuits you want. The interlock makes it physically impossible to have the main breaker and generator breaker on at the same time.
Manual Transfer Switch
Best for: portable generator owners who want a short list of pre-selected circuits, like the furnace, well pump, and fridge, on a separate switch. It's simple to use and keeps the main panel untouched.
Whole-House Standby Generator with Automatic Transfer Switch
Best for: homes that can't be without power, seasonal homes that sit empty, and anyone who doesn't want to deal with a portable generator in a storm. A permanently installed standby generator runs on propane or natural gas, starts itself within seconds of an outage, and shuts itself off when utility power returns.
Why Lakes Region Homes Need Backup Power
Tree-lined roads, nor'easters, ice storms, and summer thunderstorms mean outages here can last hours or days. And for many homes in the Lakes Region and southern Maine, losing power means more than losing the lights:
- No water: a private well pump can't run without power
- No heat: most oil, propane, and pellet heating systems need electricity to run
- Frozen pipes: a real risk for seasonal homes that sit empty in winter
- Flooded basements: sump pumps stop when the power does
- Spoiled food: refrigerators and chest freezers warm up fast
We Plan Around the Circuits That Matter Most
Every generator job starts with a load calculation. For an essentials setup, we typically prioritize the well pump, heating system, refrigerator and freezer, sump pump, some lights and outlets, and your internet. Well pumps and other motors draw a big surge when they start, so we size the generator to handle that, not just the running load. If you want the whole house covered, we'll size a standby generator to match.
Generator Safety: What Every Homeowner Should Know
- Never backfeed your home by plugging a generator into a dryer outlet with a double-ended cord. It can energize the utility lines and seriously injure line workers, and it's a fire risk in your home.
- Run portable generators outdoors only, well away from windows, doors, and vents, and never in a garage or basement. Generator exhaust contains carbon monoxide, which you can't see or smell.
- Have working carbon monoxide detectors on every level of your home.
- Use a proper interlock or transfer switch. It's the only safe, code-compliant way to connect a generator to your house wiring.
What to Expect
- Assessment & written quote: We look at your panel, talk through what you want to run, do the load calculation, and give you a firm written quote.
- Permits & planning: We pull the permits and plan placement, clearances, and fuel coordination with your propane supplier or gas fitter for standby units.
- Installation: We install the interlock, transfer switch, or standby generator and automatic transfer switch, then label everything clearly.
- Testing & walkthrough: We test the system under load, walk you through how it works, and leave you with simple upkeep tips.

An interlock is a mechanical plate installed on your electrical panel that prevents the main breaker and the generator breaker from being on at the same time. Paired with an outdoor power inlet, it lets you safely run your home’s circuits from a portable generator without any risk of backfeeding the utility lines.
Yes, if it’s sized for it and the well circuit is connected. Well pumps draw a large surge of power when they start, so we account for that when we size the generator and choose which circuits to include.
Yes. A standby generator with an automatic transfer switch starts on its own during an outage and keeps the heat, well pump, and sump pump running, which helps protect against frozen pipes and flooding even when no one is there.
Standby generators sit outside on a level pad and need set clearances from windows, doors, vents, and property lines according to the manufacturer and local code. We plan the location with you so it’s safe, close to your fuel source, and easy to service.
Yes, and it’s the most cost-effective time to do it. We can install an interlock kit and power inlet as part of your panel upgrade.
