How Long Does a Whole Home Generator Installation Take?
One of the most common questions we hear from Kansas City homeowners is: "How long will this take?" The answer is simpler than most people expect. A whole-home KOHLER® generator installation is a single-day project. Our crew arrives in the morning and you have backup power by the end of the day.
1 Day
That's all it takes. Start to finish, morning to evening.
What Happens on Installation Day
GridGuard coordinates every piece of the project in advance so that when our crew shows up, everything is ready to go. Permitting, site assessment, equipment staging — all handled before we ever set foot on your property on installation day. Here's how the day unfolds:
Your Installation Day at a Glance
How We Get It Done in One Day
The key is preparation. A lot of contractors stretch installations over multiple days because they're figuring things out as they go. GridGuard does the work upfront so installation day is smooth and efficient.
Pre-Pulled Permits
We handle all municipal permitting before your install date so there are zero delays waiting on paperwork on the day of.
Site Assessment First
We assess your property, electrical panel, and gas line access in advance so our crew arrives with exactly the right equipment.
Full Crew, Not One Guy
We send a complete installation team — not a solo technician. Everyone has a job and the work happens in parallel.
Equipment Staged in Advance
Your KOHLER® generator, transfer switch, and all materials are on-site before we start. No supply runs mid-job.

Our single-day installation covers everything needed to have a fully operational backup power system:

What Happens Before Installation Day
The only thing that takes longer than a day is the pre-installation phase — and we handle all of it for you:
Free Site Assessment
We visit your property, evaluate your power needs, and recommend the right KOHLER® system for your home.
Permitting
We pull all required municipal permits on your behalf. This typically takes 1–2 weeks depending on your city or county.
Equipment Ordering
Your generator is ordered and staged ahead of the installation date so there are no delays.
Installation Day
Our full crew arrives and completes everything in a single day.
The Bottom Line
From the moment our crew pulls up to the moment they pack their tools and leave, your KOHLER® whole-home generator installation is a one-day project. You don't need to take multiple days off work, live around a construction site, or wait weeks for your backup power to be ready.
We handle the permitting, the planning, and the prep. You handle nothing. On installation day, just be home — and by evening, your family is protected.
