Why Businesses Work With Our Team

Commercial electrical work is different from residential. You are balancing safety, code compliance, ongoing operations, and budget approval, often under time pressure. We structure our process around those realities, so you can focus on running your business while we handle the electrical side.

From the first call, we aim to give you clear information and straightforward options. We start with a free, upfront estimate, then explain what we recommend and why in plain language. You will know the scope, pricing, and expected timing before any work begins, which helps you plan around staff, customers, and other trades.

Every technician who arrives on your site has been screened, drug tested, and professionally trained. For businesses, this is often just as important as technical skill because you need to trust the people working around your employees, inventory, and equipment. Our team arrives in uniform, treats your space with respect, and communicates with your point of contact throughout the job.

We are fully licensed and insured in both New Hampshire and Massachusetts, and we have been serving southern New England commercial and residential clients since 2020. Our company offers warranties on select services, which reflects our commitment to quality workmanship and long term reliability.

Commercial clients choose Garneau Electric because:

• Our technicians are screened, drug tested, and professionally trained for safe work in occupied spaces.
• We provide free, upfront “no surprise” pricing, so you can protect your budget.
• We are fully licensed and insured in New Hampshire and Massachusetts.
• We offer 24/7 emergency response and same-day appointments when possible.
• We support ongoing needs through warranties on select services and our Club Membership program.

If you need a commercial electrical contractor Manchester leadership can feel confident approving, our combination of professional process, vetted staff, and transparent pricing is designed to make that decision easier.

Commercial Electrical Services We Provide

Every commercial property has a different mix of systems, equipment, and safety requirements. We work with building owners, facility managers, and tenants to plan and complete projects that match those needs. Whether you are dealing with a sudden problem or planning a major upgrade, our goal is to provide reliable electrical work that supports your operations.

For new spaces and renovations, we handle commercial wiring and rewiring, panel upgrades, and circuit additions for offices, production areas, and specialized equipment. We can help with tenant fit-outs, reconfigurations of existing layouts, and code corrections when an inspection identifies issues that need attention.

Lighting is a major part of how a commercial space functions and feels. We install and upgrade interior lighting for offices and retail, as well as exterior and parking lot lighting that supports security and customer comfort. Our team can replace outdated fixtures, add lighting controls, and address recurring problems like frequent lamp failures or inconsistent light levels.

Many businesses are now adding infrastructure for electric vehicles and renewable energy. We install EV charging stations for commercial parking areas and company fleets, and we provide solar wiring services for properties that are adding or expanding solar arrays. In both cases, we coordinate with your equipment providers and other contractors as needed.

Backup power is often a critical concern for commercial clients. As an authorized Generac dealer, we work with businesses that want a dependable generator system to support essential loads during outages. We install and wire generator systems, and we perform related electrical work so your key systems, such as refrigeration, servers, or life safety equipment, stay powered when the grid goes down.

Examples of our commercial electrical work include:

• New circuits, wiring, and rewiring for offices, retail, and production areas.
• Service and panel upgrades to support added load or new equipment.
• Interior, exterior, and security lighting installations and upgrades.
• EV charger installations for employee or customer parking areas.
• Solar wiring for commercial solar projects in coordination with your installer.
• Generator wiring and related work as an authorized Generac dealer.
• Code corrections, safety upgrades, and troubleshooting for recurring issues.

If you are looking for a commercial electrician Manchester leadership can rely on for both everyday maintenance and larger projects, we are ready to talk through your plans and help you choose an approach that fits your building and your budget.

How We Support Your Operations

We understand that electrical work in a commercial space is not just about the technical details. It is about when and how that work takes place, and how it affects your employees, customers, and tenants. Our team plans each project with those factors in mind so that electrical work supports your operations instead of disrupting them.

Scheduling is a key part of that approach. Whenever possible, we work with you to choose times that limit impact on your business, including off-hours or phased work if that is appropriate for the scope. During the project, we keep work areas organized and communicate clearly so your staff knows what to expect.

Commercial properties also face specific safety and compliance requirements. Our electricians follow New Hampshire electrical codes and applicable national standards, and we coordinate with local inspection processes when required. This can help you move through fit-outs, equipment changes, or safety upgrades without unnecessary delays related to electrical work.

When an emergency happens, such as a partial power loss, failed circuit, or critical equipment issue, waiting several days is usually not realistic. We offer 24/7 emergency service, and we are available for same-day appointments whenever scheduling allows. Our goal is to help you stabilize the situation and get key systems back online as quickly as is reasonably possible.

Long term, many commercial clients want fewer surprises and a better view of upcoming needs. Our Club Membership program can support that goal. Members receive benefits such as priority booking, annual safety evaluations, exclusive discounts, and extended warranties. For businesses, this can be a practical way to build electrical maintenance and upgrades into an overall facility plan.

We also understand that large electrical projects can represent a significant investment. We offer financing options and payment plans, which can make it easier to move forward with needed improvements without straining cash flow. When you combine that with free, upfront estimates and clearly defined scopes of work, you have more control over how electrical projects fit into your budget and timeline.

Working With Manchester Area Businesses

Manchester is a hub for many different types of commercial properties, from downtown offices and restaurants to medical practices, educational facilities, and light industrial spaces. Our team at Garneau Electric works with this mix of buildings regularly, which helps us understand the practical challenges that local businesses face when planning or reacting to electrical work.

Because we are based in Windham, we can reach Manchester and nearby communities efficiently for both scheduled projects and urgent calls. For many of our commercial clients, having a team that is close by matters when an issue affects customers, production, or critical systems. It can also simplify coordinating site access and walkthroughs when you are planning a renovation or expansion.

Commercial electrical work must comply with New Hampshire state electrical codes along with applicable national standards. We stay current with these requirements and work with you and your other project partners so that inspections and approvals related to electrical work proceed as smoothly as the situation allows. For businesses that operate on both sides of the state line, our licensing in New Hampshire and Massachusetts means you can work with a single electrical partner across multiple locations.

Whether you manage a single property in Manchester or a group of facilities across the region, our focus is on building a consistent, professional relationship. We want you to feel comfortable calling us for everyday questions, not just major issues, and we work to become a trusted part of how you maintain and improve your buildings.
