Three reasons the calls are picking up.
Outages are getting longer
Between hurricanes, ice storms, and grid strain, multi-day outages have become routine in the Houston area. A whole-home generator restores power automatically within seconds.
Protecting your family
Keep the AC, fridge, medical equipment, security system, and lights running through any outage. For homes with kids, elderly relatives, or medical needs, it's peace of mind.
Real return at resale
Whole-home generators typically return a meaningful share of their cost at resale and make homes noticeably more attractive to buyers in outage-prone areas like Houston.
A simple three-step process.
-
You submit your request. Fill in the short form with your name, phone, ZIP, home size, and timeline. Takes about 30 seconds.
-
We match you with a licensed local installer. We work with a small group of vetted, licensed installers serving the greater Houston area. We pass your request to the one best suited to your ZIP and timeline.
-
They call to schedule a free estimate. The installer reaches out — typically the same or next business day — to schedule a free in-home estimate. No cost, no obligation. You decide from there.
You're never charged anything to use GridHaven. The installer pays us to be connected with local homeowners. Getting a quote costs you nothing and creates no obligation to buy.
Not all generator installations are the same.
A whole-home generator installation in Houston typically runs $10,000–$18,000 depending on the size of your home, the unit brand, and site-specific work like gas line extensions and electrical panel updates. A quality installer will:
- ✓Do an in-home site evaluation before quoting
- ✓Explain the difference between generator sizes based on your home's actual load
- ✓Pull the required City of Houston and Harris County permits
- ✓Provide a written warranty on both the unit and the installation work
- ✓Handle scheduling with the utility and gas company on your behalf
The installers we work with are licensed, insured, and experienced with Houston-specific requirements. If a quote seems off, or an installer doesn't behave professionally, tell us — we take that feedback seriously.
Answers to what most homeowners ask.
Is this really free?
Yes. Requesting a quote through GridHaven costs you nothing. The in-home estimate from the installer is also free. You're only charged if you decide to move forward with an installation — and that's a decision entirely up to you.
Will I get spammed with calls and emails?
No. Your information is shared with one licensed Houston installer — the one best suited to your ZIP and timeline. We never sell your data to third parties, never add you to marketing lists, and never share your info beyond the single installer who will contact you.
Who will call me and how soon?
A licensed installer who serves your Houston-area ZIP code will call, typically within the same or next business day. They'll introduce themselves, ask a few questions about your home and needs, and schedule a free in-home visit at a time that works for you.
What does a whole-home generator actually cost?
Installation typically runs $10,000–$18,000 for the greater Houston area. Actual price depends on the size of the unit needed for your home, the brand (Generac tends to be the most affordable, Kohler is premium), and the complexity of your gas line and electrical panel work. The installer's free estimate will give you an exact number for your specific home.
How long does installation take?
From the day you sign a contract, installation typically takes 4–8 weeks. This includes permit approval from the City of Houston or Harris County, unit delivery, site prep, installation, and final utility inspection. The installer will walk you through the timeline during your estimate.
Do you install the generator yourselves?
No. GridHaven connects homeowners with independent, licensed Houston installers. We aren't the installer — we're the matchmaker. This lets you get quotes from qualified local professionals without having to research and vet them yourself.
What if I'm just researching and not ready to install right now?
That's fine — many homeowners request a quote months before they're ready to install. Just select "Just researching" as your timeline and the installer will provide a quote you can hold onto without any pressure to move forward.
