Most home care totals move with the blocks of time an agency sells, not with the single hour a family pictures when it starts asking questions. Before you compare any two agencies, write down the shape of the week: how many separate visits you expect, how long each one runs, which days repeat, and whether any part of the day or night needs someone awake in the house. The same weekly need can produce very different totals depending on how each agency packages it. Treat the packaging rules as part of the decision, not as fine print to read later.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Minimum blocks and rounding
Agencies commonly sell time in minimum blocks, and the rounding rule often matters more than the rate sheet. Ask the shortest visit the agency will schedule, whether a shorter request is rounded up to the next block, and whether a longer visit is billed in steps or in continuous time. A visit that falls just under a block boundary can cost the same as a longer one. Ask for the rounding rule in writing, then test it against the visit lengths on your list. If the list says a visit runs thirty minutes and the minimum block is an hour, the schedule you planned is not the schedule you will be billed for.
What it costs: The Missouri median for non-medical in-home care is $33 an hour, per the CareScout (Genworth) Cost of Care Survey 2025 state data tables, released March 2026. New Plan Care's standard rate is $34 an hour with a four-hour minimum, so a visit starts at $136 (newplancare.com/services).
Overnight coverage comes in different forms
Overnight help is not one service. An awake overnight aide, an aide who sleeps in the home and responds when called, and a scheduled check-in visit are different jobs with different totals and different expectations for the family. Ask which form the agency offers, what counts as a call during the night, how long a response is expected to take, and whether the same person stays for the whole night or the shift changes partway through. Ask what happens when the scheduled aide cannot come in, whether a replacement is billed at the same terms, and how the agency tells the family that a change was made. Write the answers next to the form you chose so the comparison stays concrete.
Live-in and long-shift arrangements
A live-in arrangement and a long daily shift are two separate decisions, and agencies often describe them with the same language. Ask what the agency counts as a full shift, how meal breaks and sleep time are treated, what the days off look like, and how a day off is covered when the regular aide is away. Ask whether the terms change when more than one person in the household needs help, and whether a room, a vehicle, or a phone is expected from the family. Compare the written terms line by line, not the verbal summary given on the call.
A checklist before you tour
Bring a one-page list to every tour so the agencies are measured against the same week. Write the expected visits by day and start time, the longest single shift, the overnight need in one of the three forms above, any weekend or holiday coverage, and the days when no one is available. Add the tasks the family will keep for itself, since those change how many hours are actually needed. Note which decisions belong to the family, the doctor, or the household's other helpers, and leave them off the agency's scope. Health questions go to the family's doctor, and the agency should be asked only about the non-medical hours it would staff.
Questions to ask on the tour
Ask for the rounding rule, the minimum block, and the overnight form in writing before you leave. Ask how the agency schedules a change on short notice, what notice it asks the family to give for a change or a stop, and whether any charge applies when the family cancels a booked shift. Ask how many aides regularly work the household, how the schedule is set, and who the family calls when a visit is missed. Ask for a sample weekly schedule built from your list, not from the agency's standard package, and ask the office contact to walk through it line by line. If the answers differ from one person to the next in the office, write down the version you were given and ask for it in the agreement.
Plan one week around the blocks
Build a single week on paper before you sign anything. Put each planned visit into its block, mark where rounding would add time, and mark every hour that falls outside any block, such as a night, an early morning, or a holiday. Then count the gaps where no one is scheduled, because those are the hours most often missed when a family assumes coverage that was never booked. Once the week is mapped, you can compare two agencies on the same schedule, which is more useful than comparing their headline terms. Revisit the map whenever the household's needs change, since the same blocks rarely fit the next month.
Local resources, in general terms
Several public offices in the St. Louis area can help a family think through home help without selling any particular agency. Your county's aging services office is a common starting point for information on in-home options. The state long-term care ombudsman program handles complaints about care settings and can explain what a family's rights are when a service changes. For a broader view of where help is available in the region, the caregiver supply map explains how to read local supply, and the page on finding help where supply is thinnest shows how availability can affect the schedules you are able to book.
Read the full set of terms before the first shift, and keep a copy of the weekly map with the agreement so the planned week and the billed week can be checked against each other as the arrangement runs.
