Preventive home maintenance · St. Charles County
Catch the $200 fix before it becomes a $5,000 repair.
A monthly membership that sends a trained technician to your home every season. We run an inspector-grade checklist, handle the small stuff, and send you a clear report on what your house needs next.
How it works
Your house gets a maintenance schedule, like a commercial building does.
Baseline assessment
A two-hour first visit. We record your furnace, AC, water heater and roof ages, find your shutoffs, label the panel, and photograph everything.
Seasonal visits
We come back every spring, summer, fall and winter on a set schedule. You don't have to remember a thing.
Small fixes on the spot
Running toilets, loose hinges, tired caulk, a dead GFCI. Included time on Complete and Premier plans.
A report you can use
Within 24 hours you get photos, a home health score, and findings sorted into fix now, plan for, and monitor.
Membership plans
Pick the level of care your home needs.
Every plan starts with a baseline home assessment ($149, free on annual plans). Cancel with 30 days' notice after your first year.

For older homeowners and their families
Stay in the home you love, and off the ladder.
Gutters, smoke detector batteries and furnace filters are the jobs that lead to falls. We take them off your list for good.

- The same technician whenever possible, in uniform with photo ID
- A phone call before we arrive, and written prices before any extra work
- Reports shared with a son or daughter, with your okay
- Gift memberships for parents
