A stairlift installation typically takes 2–4 hours for a straight staircase, but curved stairs and custom setups can stretch to a full day or more. The timeline depends on your staircase layout, existing structural conditions, and whether electrical work is needed. Understanding what happens during installation helps you plan your day and set realistic expectations.
Typical Installation Timeline for Straight Staircases
Most straight stairlifts are installed in 2–3 hours. A technician arrives with the pre-assembled chair, rail sections, and mounting brackets. They'll measure your staircase (even though measurements were taken during the sales visit), position the rail along the stair edge, secure the brackets to each step or wall, and attach the chair to the rail. Finally, they test the lift's movement, check safety features like the obstruction sensor, and walk you through basic operation.
This timeframe assumes no complications: your stairs are structurally sound, there's adequate headroom at the top and bottom landings, and no hidden obstacles like loose treads or uneven steps.
Curved Staircase Installations Take Longer
A curved stairlift requires custom rail fabrication, which adds 3–7 days (sometimes longer) before installation even begins. Once the custom rail arrives, installation itself typically takes 4–8 hours or may require two visits. The technician must carefully align the curved rail, which demands more precision than straight installations and often involves more mounting points.
If your home has a spiral or multi-level staircase, expect 1–2 weeks total turnaround and potentially two separate installation appointments.
Pre-Installation Preparation (24–48 Hours Before)
Before the technician arrives, clear your staircase completely. Remove rugs, toys, boxes, and anything stored under the stairs. If you have pets, arrange for them to be in another room—they can become startled by drilling and movement. Ensure the technician has clear access to both the top and bottom landings with space to maneuver tools and equipment.
Confirm electrical outlet availability near the stairlift's designated charging position. Most battery-operated chairs charge at the bottom of the stairs, but some models prefer top-stationed charging. If no outlet exists nearby, the technician may recommend an electrician visit beforehand—this adds an extra day and $150–$300 to your overall project cost.
What Happens During the Actual Install
Here's the step-by-step breakdown:
- Mounting bracket installation: Brackets are secured to steps or walls using masonry anchors or wood screws, depending on your staircase material.
- Rail alignment and attachment: The rail is positioned and bolted to the brackets with shimming for perfectly level tracking.
- Chair assembly and testing: The seat, armrests, and footrest are attached to the carriage, then the whole assembly is placed on the rail.
- Safety checks: The technician runs the lift up and down, tests the seat belt, emergency stop button, and obstacle sensors.
- User training: You'll receive a 15–20 minute walkthrough covering basic operation, charging, and what to do if the battery runs low.
Factors That Can Extend Installation
Expect delays if:
- Your staircase has unusual angles or landings (adds 1–3 hours)
- Wall material is plaster or tile requiring special anchors (adds 30–60 minutes)
- Electrical work is needed to install a nearby outlet ($300–$600, plus 1–2 additional days)
- The staircase shows structural issues like warped treads or loose railings (may require repairs before installation proceeds)
- Multiple stairlifts are being installed in one home (double the time)
After Installation: Setup and Adjustments
Once the technician leaves, the stairlift is operational. However, some models require initial charging for 12–24 hours before first use. Ask whether your unit needs this before the technician departs. If you notice the chair moving unevenly or making unusual noises within the first week, contact the installer—most companies offer a 30-day adjustment period at no extra charge.
When comparing providers through Mercoly, check whether their quoted installation time includes user training and whether follow-up adjustments are free or charged.
Frequently Asked Questions
Q: Can my stairlift be installed the same day I purchase it? A: For straight staircases with inventory in stock, yes—you could purchase in the morning and have it installed by evening. Curved lifts require custom fabrication, so expect 1–3 weeks.
Q: Do I need to be home during the entire installation? A: Yes. The technician needs someone to grant access, answer questions about your layout, and receive the safety training. The process is straightforward but requires your presence.
Q: Will installation damage my stairs or walls? A: Professional installation uses appropriate fasteners for your surface (wood anchors for drywall, masonry anchors for concrete). Damage is minimal and rarely visible once brackets are mounted. Holes left after removal are typically 3–5mm and easily patched.
