Standby Home Generators in Richmond, Chesterfield & Henrico
Generac home standby generators installed by a local, owner-operated team — 30 years of experience, honest recommendations, and peace of mind when the lights go out.
Commonwealth Construction & Remodelinginstalls Generac standby home generators for homeowners throughout Richmond, Chesterfield County, Henrico County, and the surrounding Virginia communities.
When a summer thunderstorm, ice storm, or passing tropical system knocks out the power, a standby generator keeps your home running — heating or air conditioning, the refrigerator, the sump pump, lights, and medical equipment — usually within seconds and without you lifting a finger. When you work with us, you deal directly with the business owners, not a commissioned sales rep, so the generator you end up with is sized for what your home actually needs, not the biggest unit we can sell.
A generator is only as reliable as its installation. Placement, the pad it sits on, the fuel connection, and the transfer switch all have to be done right and to code for the system to start when you need it. With 30 years of experience, we plan every installation carefully, coordinate the details, and back the work with some of the best warranties in exterior remodeling.
Why Homeowners Choose Commonwealth for Standby Generators
Backup power protects your home, your comfort, and your family when the grid goes down. Here's what sets Commonwealth apart for homeowners across Richmond, Chesterfield, and Henrico.
You work directly with the owners.
No high-pressure sales appointment, no "sign tonight for this price" tactics — just a straight conversation about what your home needs.
Sized to your home, not the sales sheet.
We look at what you actually need to keep running during an outage and recommend a generator that covers it — without paying for capacity you'll never use.
Automatic, hands-free backup power.
With an automatic transfer switch, your Generac generator senses an outage and takes over on its own, then shuts down when utility power returns. Mobile Link Wi-Fi monitoring lets you check on it from your phone.
Local experience that reads your home right.
Thirty years working in the Richmond area means we understand how local homes, storms, and outages affect a generator project.
Honest, range-based pricing.
We explain what drives cost and give you clear expectations up front, rather than a one-size number designed to win the sale.
Craftsmanship with real warranties.
Every install is completed with attention to detail and backed by strong product and workmanship warranties.

Generator Options
The right generator comes down to how much of your home you want to power, the fuel available at your property, and your budget. We install Generac home standby generators, the leading name in home backup power, and we’ll recommend the model and size that fit your home rather than the biggest unit on the lot.
Generac’s Guardian series covers everything from essential-circuit systems to whole-home coverage, runs on natural gas or propane, and tests itself weekly so you know it’s ready. We’ll walk you through how each option performs on capacity, fuel, noise, and long-term maintenance, so the final choice is genuinely yours.

Natural gas
Convenient and continuous; if your home already has natural gas service, the generator runs without refueling for as long as the outage lasts.

Propane
A dependable choice where natural gas isn't available, running from an on-site tank sized to carry your home through extended outages.

Whole-home or essential circuits
Power everything in the house, or just the essentials like HVAC, refrigeration, well and sump pumps, and lighting, depending on your needs and budget.
Signs It's Time for a Standby Generator
- Your neighborhood loses power during storms more than once or twice a year
- Someone in your home relies on medical equipment that needs electricity
- You have a sump pump, well pump, or basement that’s at risk when the power goes out
- You work from home and can’t afford to lose power or internet
- You’ve lost food, comfort, or sleep to summer heat or winter cold during an outage
- You’re tired of hauling out, fueling, and running a portable generator
If any of these sound familiar, a free estimate will tell you what size generator makes sense for your home — and we’ll tell you honestly if a smaller essential-circuit system will do the job.

Serving Richmond, Chesterfield & Henrico
We install standby generators throughout the Richmond metro area, with a focus on Richmond, Chesterfield County, and Henrico County, plus surrounding Virginia communities. As a locally owned and operated company native to the area, we’re a short drive away and invested in the neighborhoods we serve.
Power outages are a fact of life in Central Virginia. Summer thunderstorms bring high winds and falling limbs, the region’s mature tree canopy puts overhead lines at risk in every storm, winter ice storms weigh down branches and wires, and the remnants of tropical systems moving up from the coast can leave neighborhoods in the dark for days. Long, hot, humid summers make an outage more than an inconvenience, and a winter outage can mean no heat and frozen pipes.
For homeowners here, the questions worth asking come down to what you can’t afford to lose: air conditioning or heat for older family members, a sump pump in a wet basement, a well pump, a refrigerator full of food, or a home office. When we plan a generator in the Richmond area, we’re drawing on 30 years of local experience with these homes and this weather to make sure your system is sized right, placed right, and ready when the power goes out.

I can tell you Tim’s work is exceptional. They made our vision come true on both decks they built for us. Not only that they saw some items that were done incorrectly on the original construction of our home and corrected so we would not have issues. The are very easy to work with and they are very reasonable pricing and detailed to their workPosted on Google![]()

Extremely responsive. A contractor who doesn't give you the run around, does what he says he's going to do and does it well. Highly recommend. Will use again!
How much does a standby generator cost in the Richmond area?
Cost depends on the size of the generator, whether you want whole-home or essential-circuit coverage, your fuel source, the distance to your gas line or tank, and any electrical panel upgrades. Rather than quote a flat figure, we provide an honest price range during your free estimate and explain exactly what’s driving it.
How long does generator installation take?
Most installations take a few days of on-site work once the equipment is in hand, though permits, inspections, and utility coordination can add time before and after. We’ll give you a realistic timeline up front and keep you informed throughout.
What size generator do I need?
It depends on what you want to power. A system that covers a few essential circuits needs far less capacity than one that runs your whole home, including central air. During your free estimate, we look at your home and your priorities and recommend the right size, not the biggest one.
Should I choose natural gas or propane?
If your home already has natural gas service, it’s usually the most convenient fuel because it never needs refilling. Propane is a reliable option where natural gas isn’t available. We’ll walk you through which makes more sense for your property.
Does the generator turn on automatically?
Yes. A standby generator paired with an automatic transfer switch senses an outage, starts on its own, and powers your home within seconds, then shuts down when utility power returns. You don’t have to be home for it to work, and it runs a short self-test each week so you know it’s ready.
What brand of generator do you install?
We install Generac home standby generators. Generac is the leading name in home backup power, and its Guardian series covers everything from essential circuits to whole-home coverage. Mobile Link Wi-Fi monitoring lets you check your generator’s status and maintenance alerts from your phone.
