Nearly 2.7 million Americans were injured on stairs, ramps and floors in 2023, according to the U.S. Consumer Product Safety Commission’s data. For people with mobility challenges, stairs pose an even greater risk — and often become impossible to navigate without assistance.

If you can no longer safely go up and down stairs, a stair lift offers independence and peace of mind. Installation involves professional assessment, rail attachment to your stairs and careful system assembly. The process starts weeks in advance with measurements and planning. Knowing what to expect at each step helps you prepare and ensure everything goes smoothly.

Consultation and measurements

Getting a professional stairway consultation is the first step to installing a stair lift. “Not every stairway can accommodate a stair lift, or it may require a different type of lift or additional equipment,” explained Shane Campbell, business development manager at Options HME, Inc., a stair lift dealer. This evaluation assesses your staircase’s physical layout and mobility needs.

Most consultations are free and take about 30 minutes.

You can get an evaluation in one of two ways: Schedule an in-home visit or provide photos and measurements to your dealer. “[Don’t] proceed with purchasing a stair lift if the dealer hasn’t seen photos of the stairway or seen the stairway in person,” Campbell stressed. Phone descriptions alone don’t provide enough information.

Stair lift costs range anywhere from $2,000 to $15,000, so it’s smart to compare a few quotes and consider your financing options before committing to an installer.

Pro tip

Request an in-home visit if your staircase has turns or landings. Complex staircases require more detailed assessments to avoid unnecessary modifications and substandard installation. Proper evaluation also ensures installers attach the lift to your staircase structure rather than walls, preventing structural damage.

What installers consider

Mike Peck, vice president of installation at Leaf Home, noted that the evaluation results help identify the most efficient solutions with minimal home modifications while ensuring safe access for all household members. During the assessment, installers measure these key dimensions:

  • Overall staircase length
  • Width from wall to wall (or wall to handrail)
  • Available space at the top and bottom landings

Preparation for installation

Getting ready for stair lift installation day is straightforward. Usually, all you have to do is clear the stairway of items and ensure the top and bottom landings have enough clear space, according to Campbell. How much space you need to clear depends on which lift type you’re getting.

  • Straight stair lifts are relatively simple. “Installation typically takes place entirely within the stairwell,” Peck said. You’ll need to clear the staircase and remove nearby wall decorations to avoid damage.
  • Curved stair lifts require more preparation. Peck noted that you’ll need to clear more areas as these units often include custom entry and exit points beyond the stairwell, such as landings or hallways. Besides this, installers may need a protected workspace — ideally about the size of a car — for staging and adjusting the equipment.

Installation time varies by lift type, Campbell said. Straight stair lifts are usually installed within two to five weeks since dealers often stock them. In contrast, they rarely stock curved stair lifts because manufacturers must create each rail to match a staircase’s unique dimensions and turns. This extends installation timelines to four to six weeks.

Pro tip

Most homes already have electrical outlets to charge the lift’s battery. If yours doesn’t, an electrician can help you install one.

The installation process

Stair lift installation moves quickly once technicians arrive at your home. “Most take about half a day,” Peck said. Throughout the process, they take safety measures to minimize disruption and work methodically to reduce noise. There are four main steps:

  1. Rail attachment: Secure the track system directly to your stair treads, not the walls.
  2. Carriage threading: Thread the motorized carriage (or chassis) onto the newly installed rail.
  3. Chair mounting: Attach the seat, armrests and footrest to the carriage.
  4. System testing: Fine-tune everything and test the stair lift for smooth operation.

What to expect

Most installations generate only moderate sound levels, similar to typical home improvement projects. While you can remain home during installation, technicians often advise staying in another room to avoid the dust from drilling.

After the installation, your technician won’t just leave you with the equipment. Peck said that they’ll walk you through how to operate it safely and confidently. You’ll learn basic controls, safety features and maintenance tips before they walk out the door. With this hands-on training, you’ll feel comfortable using your new stair lift from day one.

Post-installation care

Maintaining your stair lift after installation ensures years of safe, dependable operation. “Stair lifts generally require minimal maintenance, though service needs may vary depending on the model,” Peck emphasized.

Regular professional servicing extends your lift’s lifespan and maintains warranty coverage. Most manufacturers recommend yearly inspections to catch issues early. However, you should schedule a service appointment right away if you notice odd noises, jerky movements or slow operation.

Stair lift maintenance tips

Most homeowners find that a few simple habits keep their lifts running well and help avoid unexpected breakdowns.

  • Keep it clean: Wipe surfaces regularly to prevent dust and debris buildup.
  • Clear obstructions: Remove items from the track and stairs before each use.
  • Charge properly: Always park the lift at its charging point when not in use.
  • Check lubrication: Some models need periodic lubrication of moving parts (follow manufacturer guidelines).
  • Practice operation: Use your lift regularly to stay familiar with controls and safety features.

DIY vs. professional installation

Can you install a stair lift yourself? Technically, yes, but experts advise against it. Campbell said that professional local dealers install the safest and most reliable lifts. Unless you’re a stair lift installer, the do-it-yourself route can create frustrating challenges:

  • If you make a mistake, getting help becomes difficult.
  • Poor placement can block other family members from using the stairs safely.
  • Repairs may be costly if you end up hiring a professional after attempting to self-install.

If you're determined to DIY, stick to straight stair lifts. They're simpler since they follow a linear path without custom curves or complex programming. "Proper measurements are critical on curved stair lifts," Campbell cautioned. One wrong measurement can leave you with expensive equipment that doesn't fit.

    Stair lifts need regular cleaning, track lubrication and safety checks to run smoothly. You should also inspect for loose parts and listen for unusual sounds during operation. Most maintenance tasks are simple and help extend your stair lift’s lifespan.

    How long does a stair lift battery last?

    With normal use, you can expect your stair lift battery to last three to five years. Daily usage, stair length and weight load affect your stair lift’s battery longevity.
