Outdoor Structures

Outdoor structures that Thompson's Electrical Service provides wiring for include:

  • Decks, Patios & Porches
  • Storage sheds & Workshops
  • Detached garages & Carports
  • Tiny homes & small cabins
  • Home offices & Studios
  • Greenhouses & Garden houses
  • Gazebos, Pavilions & Pergolas
  • Small Barns & Chicken Coups
  • Pool & Spa Houses
  • Outdoor kitchens

 

Due to obstacles and weather exposure, extending power outdoors should be done underground using underground feeder wire or conduit.  Thompson's Electrical Service will provide any trenching, conduit installation and underground feeder wire installation required to power your outdoor structure. 

If you do choose to dig out the trench yourself, be sure to know where you are digging and if there are any other underground utilities (gas, electric, water, etc..) that you may run into. Remember to call 811 before your do any digging!  

What are some of the advantages of custom wiring from an independent electrician over factory wiring:

Custom wiring by an independent licensed electrician offers several advantages over factory/warehouse pre-wiring (common with pre-built sheds, workshops, garages, small cabins, or tiny houses). The choice depends on your needs, budget, and structure type, but custom work excels in flexibility and site-specific optimization.  Another thing to consider is that often at the factory the personnel wiring the structure may not even a certified electrician. 

Factory pre-wiring is often cheaper upfront and faster because everything arrives ready-to-connect, with consistent quality in a controlled environment. However, you will still need a local licensed electrician for the feeder run from your house, final hookups, and any other adjustments, potentially adding additional costs.

Custom wiring by a licensed electrician shines for permanent, heavily used structures or when codes and performance matter. Costs are generally higher when it comes to labor + materials, but it often provides better value and electrical safety over time.

Other Advantages:

Tailored to Your Exact Needs and Site Conditions
  • A licensed independent electrician designs the layout around your intended use.  For example, a workshop with 240V tools, home office with dedicated circuits, or greenhouse with specific lighting/heating.
  • Factory wiring often uses standardized, basic setups that may not match high-draw equipment or future expansions.
  • A licensed independent electrician accounts for local terrain, distance from the main panel, soil type, burial depths, weather exposure, local code variations, and obstacles.
  • Factory wiring assumes generic conditions and may need rework on-site anyway.

Full Code Compliance and Permitting
  • Local licensed electricians are familiar with the NEC. 
  • Pre-wired units are typically built to minimum manufacturer standards, which may not fully align with local requirements for outbuildings, leading to modifications or failed inspections.
  • Proper separation of neutrals/grounds, correct grounding electrodes, GFCI protection, and disconnects are handled correctly for your jurisdiction.

Higher Quality Materials and Workmanship
  • Electricians can use premium, weather-resistant components.  For example we use better conduit, heavier wire gauge for voltage drop over distance, and upgraded panels.
  • Factory work may prioritize cost and speed, sometimes resulting in minimal or lower-grade materials.
  • On-site installation allows for better protection against moisture, rodents, and physical damage.

Easier Future Modifications and Scalability
  • Custom work makes it more convenientto add circuits, outlets, lighting, or subpanels later.
  • Factory pre-wiring can be harder to expand or upgrade without tearing out standardized setups.
  • Integration with smart home systems, generators, solar, or EV chargers is simpler when planned upfront by a local licensed electrician.

Professional Accountability and Warranty
  • With a licensed electrician, you get direct communication, a local point of contact for service calls, and often better warranties. 
  • Issues with factory wiring might involve shipping the structure back or dealing with the manufacturer’s limited support.
  • Proper installation lowers chances of fires, shocks, or insurance denials.

Optimized Performance and Efficiency
  • Better load calculations prevent voltage drop or overloaded circuits on longer runs.
  • Custom placement of outlets, switches, and lights for your workflow, For example, task lighting in a workshop or RV charging outside a garage.
  • Potential for energy-efficient designs or integration with your home’s existing system.
