When a homeowner is about to spend eight to fifteen thousand dollars on a whole-home standby generator, they research the installer hard before they ever call. Your website is the deciding document. Yet most generator installers either overpay a big agency for a slow brochure site, or underpay for a template that ranks nowhere and converts no one. So what should a real website actually cost? This post breaks down the honest numbers: build fees, monthly costs, what drives return on a high-ticket trade like standby power, and where installers waste money. By the end you will know what to pay, what to skip, and how to judge whether a quote is fair for a Generac or Kohler dealer.
Ask three web companies to quote a generator installation site and you will get three wildly different numbers: $800, $6,000, and $18,000. The spread exists because they are selling completely different things. The cheap option is a five-page template someone fills in over a weekend. The expensive option is a custom-designed brand site with photography and a project manager. Neither is built to rank for 'whole house generator installation near me' or to convert a nervous homeowner comparing your ATS and load-calc process against the dealer down the road.
The trap is judging a website by its build price alone. A $600 site that never appears on page one of Google costs you far more than a $250-per-month site that lands two extra 12kW installs a year. On an $8,000-to-$15,000 average ticket, a single job pays for years of a good website. The real question is not 'what does it cost' but 'what does it return' — and for a high-ticket, storm-driven trade, the return math is unusually generous.
Understanding the model tells you what you are actually buying and where the ongoing value sits.
The parts of a website that make you money are not the ones that cost the most to design. They are the ones tied to how homeowners buy backup power. A homeowner who just sat through a three-day outage is ready to spend, and the installer whose site loads fast, answers 'how big a generator do I need,' and shows real installs wins the estimate. That means content depth, page speed, and trust signals matter more than a fancy animated hero.
The highest-ROI features are honest and boring: a load-sizing explainer that walks through 18kW versus 24kW, service-area pages for each town you cover, a clear maintenance-plan page, financing details on the $10k-plus ticket, and a quote form that captures the address and fuel type up front. Ranking and local visibility are where most of the money hides, which is why tying your build to a real program like local SEO for generator installation matters far more than paying extra for custom illustration.
The most common waste is a beautiful one-time build with no ongoing SEO. It looks great the day it launches and then sinks in the rankings because nobody adds pages, earns citations, or updates it for the next storm season. You paid $9,000 for a digital brochure that generates almost no calls.
The second waste is paying for features homeowners never use — booking widgets for a service that requires a site visit and permit, live chat nobody staffs, or stock photos of generators that are not yours. Homeowners spending $12,000 want to see your actual crew setting a Generac on a concrete pad in a yard that looks like theirs. Spend on real photography and real content, not decoration.
Before you sign anything, ask the vendor four questions. First, does the price include ongoing SEO and content, or just a one-time build? Second, can they show ranking results for other contractors in competitive trades? Third, will you get service-area pages for every town you cover? Fourth, can you see a live dashboard of where you rank, or are you trusting a monthly PDF?
For most generator installers, a predictable $249-per-month done-for-you model beats both the cheap template and the big lump sum. It aligns cost with results, keeps the site improving through outage season, and turns your website into a lead engine instead of a sunk expense. When one recovered 22kW install covers most of a year, the math is not close.
