A ramp can look finished and still leave you with a route your mother cannot use. The test is not whether a structure reaches the door. The test is whether she can travel from her usual chair, cross the threshold, move along the ramp and reach the car without an improvised lift, turn or rescue.

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.

Follow the installation from the first walk-through to the first real trip. At each step, decide what makes the house hold and what needs to go back to the care team.

1. Start with the whole trip, not the place where a ramp might fit

Begin where she normally sits. Follow the route she would take to leave the house. Check the floor, hallway, doorway, threshold, porch, proposed ramp, sidewalk and vehicle pickup point. Open every door in the direction it actually swings. Place furniture where it normally lives.

The route holds when the chair can approach the door, line up with the opening, cross the threshold and continue without a tight turn or a helper pulling from an unsafe position. Mark any point where a door, rug, storm door, step or narrow passage interrupts the trip.

Make it a care team question if you do not know which chair she will use, whether she is expected to move it herself, or how much help another person should provide. The installer needs the real movement plan, not a guess.

2. Bring the person, chair and helper into the measurement

Ask the installer to measure the chair at its widest point and at its longest turning position. Include footrests, wheels, handles, bags and any equipment that travels with her. If someone will push, include the helper's body and hand position in the space needed.

The route holds when there is room to move without scraping hands, lifting the chair over an edge or stepping off the ramp to make a turn. If she uses more than one mobility device, decide which one the ramp must accommodate.

Make it a care team question if her sitting position, foot support, balance or transfer method is unsettled. A ramp built around the wrong chair or the wrong kind of help may solve the doorway and miss the person.

3. Set the slope, landings and door operation before the quote is final

Ask the installer to mark the proposed ramp on the ground. Have the plan show each run, turn and level landing. Check where the lower end meets the walk or driveway and where the upper landing meets the threshold. Stand where a helper would stand while opening and closing the door.

The route holds when she can wait on a level surface while the door is unlocked, opened and secured. There must also be a workable place to stop after a turn and at the bottom of the ramp. Water should have somewhere to go without collecting on the travel surface or at either end.

Make it a care team question if she cannot wait safely while a door is handled, if fatigue changes how far she can travel, or if the planned slope assumes more self-propelling or helper strength than the care plan expects.

4. Make the written scope name the complete installation

The proposal should identify the route, dimensions, materials, surface, edges, rails, landings, threshold work and connection points. It should say who prepares the ground, moves plants or fixtures, handles permits, schedules inspections and repairs disturbed siding, paving or landscaping.

Ask how the ramp will be anchored, how water and snow will leave the surface, and whether access to utilities, doors, windows or bins will be blocked. If the ramp is modular or removable, ask who owns each part and what removal includes.

The house holds when the written job reaches from the interior threshold to a stable destination outside. An unlabeled patch of gravel, mud or broken pavement at the bottom is still part of the route.

5. Protect the route during installation

Before work begins, agree on how your mother will enter and leave while the usual doorway is unavailable. Confirm where tools and materials will be stored, which doors may be blocked and how the crew will secure the area when nobody is working.

Keep the chair available so the installer can check clearances before every connection becomes difficult to change. Ask to see the upper landing, turns and bottom transition before the final fastening or finish work is complete.

Make it a care team question if the temporary route requires a transfer, step or lifting method that has not been planned. Installation day should not quietly create a harder trip than the one the ramp is meant to replace.

6. Accept the ramp with a real trip and a handoff

Do not stop at a visual inspection. Use the expected chair, helper and doorway. Travel from her usual room to the outside destination, then come back in. Test every turn, pause and threshold. Open and close the door from the positions the person and helper will actually occupy.

Look for rocking, flexing, sharp edges, loose rails, abrupt transitions and places where wheels, feet or a helper's shoes can leave the surface. Test after ordinary watering or rain if possible so you can see where water sits and how the surface feels when wet.

Before final signoff, collect the permit or inspection record if one applies, the written warranty, maintenance instructions and the name to call about movement, drainage or a loose part. Photograph the completed route and keep the documents where another family member can find them.

The house holds when the full trip works without a last-minute lift, shove or workaround. If the first real trip exposes a problem with her movement or the amount of help required, pause and take that exact problem back to the care team. The ramp and the care plan have to describe the same journey.
