Ask an Installer: 20 Questions We Hear Every Week
How "Ask an Installer" Works
We coordinate with licensed installers across all 50 states. When a homeowner asks a technical question during their assessment — or before scheduling one — we route that question to an installer with hands-on experience in the specific scenario. These are technicians with 10 to 20 years in the field, not sales staff reading from a script.
Every response comes from an installer who carries active state contractor licensing, minimum $2M general liability insurance, manufacturer certification, and at least 50 documented residential installations. Questions are typically answered within a few hours during business days.
Staircase & Structure Questions
1. Can you install a stairlift on a spiral staircase?
Not with a standard residential stairlift. Spiral staircases have helical geometry and narrow treads — typically 4 to 6 inches at the inner radius — that cannot support a rail mount or allow safe seated travel. The alternatives are a vertical platform lift or a through-floor lift, both of which bypass the staircase entirely.
2. Will installation damage my hardwood stairs?
Mounting uses stainless steel lag bolts that create 5/16-inch holes spaced every 3 to 4 treads. When the stairlift is removed, the holes are filled with color-matched wood filler and sealed with polyurethane. On most hardwood, the repairs are nearly invisible after finishing.
3. My staircase is only 27 inches wide. Will a stairlift fit?
Standard units require a minimum 28 inches of clear width. However, slim-profile models like the Bruno Elite SRE-2010 and the Handicare 1100 work in staircases as narrow as 26 inches. Below 26 inches, a through-floor lift is the recommended solution.
4. My stairs have a 90-degree turn and a landing. What does that require?
A custom curved rail, fabricated to the exact measurements of your staircase. A technician laser-measures every turn and landing, sends the data to the factory, and the rail is CNC-bent to match. Fabrication takes 1 to 3 weeks. A single 90-degree turn is the most common curved installation scenario.
5. Does the stairlift mount to the wall or the stairs?
Every residential stairlift mounts the rail to the stair treads, not the wall. The treads provide the structural integrity needed to support the combined weight of the unit and the rider. The only component that may touch the wall is the charging strip at the top or bottom parking position.
Electrical & Mechanical Questions
6. The nearest outlet is 15 feet from the staircase. Is that a problem?
The charging station needs an outlet within 6 feet. Two options: install a new dedicated outlet ($150 to $350, takes 1 to 2 hours by a licensed electrician) or use a low-profile cord channel along the baseboard, though this creates a potential trip hazard and is not the preferred solution.
7. What happens during a power outage?
Stairlifts run on DC battery-powered motors, not direct AC power. The outlet charges the batteries; it does not power the lift directly. A fully charged battery bank provides 8 to 20 complete round trips, which covers a full day or more of normal use. Batteries recharge automatically when power returns, typically within 4 to 8 hours.
8. How much weight can a stairlift carry?
Exceeding rated capacity voids the warranty and stresses the motor, gears, and rail mounts. Always select a unit rated for at least 10% above the rider's current weight to account for fluctuation and items carried.
9. What maintenance does a stairlift need?
- Monthly: Wipe the rail with a dry cloth to remove dust and debris.
- Every 6 months: Apply silicone spray lubricant to the rail surface.
- Annually: Professional service inspection — $100 to $175 depending on location.
- Every 3-5 years: Battery replacement — $80 to $150 per pair.
Special Situations
10. Can a stairlift be installed outdoors?
Yes. Outdoor models use sealed motor housings, marine-grade vinyl upholstery, and weather-resistant rail coatings. Operating temperature range is 0 to 120 degrees Fahrenheit. Ice buildup on the rail must be cleared before use — do not operate the lift on an iced rail.
11. I rent my home. Can I still get a stairlift?
You need the landlord's written permission. Under the Fair Housing Act, landlords of properties with 4 or more units must allow reasonable disability modifications at the tenant's expense. Rental stairlift agreements are available — monthly fee with removal upon move-out — which avoids the full purchase cost.
12. My stairs have open risers (floating staircase). Is installation possible?
Open risers are acceptable if the treads are solid and at least 1 inch thick. Floating staircases require a structural assessment; some need reinforcement brackets added beneath the treads, while others are structurally unsuitable for rail mounting. This is determined during the free in-home assessment.
13. How fast can you install in an emergency?
Straight rails, if in stock and the outlet is ready: 3 to 7 days from initial call. Curved rails require custom fabrication: 1 to 3 weeks minimum. For emergency situations (hospital discharge, recent fall), we can deploy a temporary straight-rail unit on the longest straight section while the curved rail is fabricated.
Frequently Asked Questions
Request a free assessment through our form or call us. Your question is routed to a certified installer in your area. Most questions are answered within a few hours during business days; complex situations may take up to one business day.
Installers. Every technician in our network holds manufacturer certification, active state licensing, and has a minimum of 5 years field experience. These are the people who drill the bolts and test the safety sensors, not salespeople reading from a product sheet.
No. Technical questions and the in-home assessment are free with no obligation. If you have a third-party unit that needs hands-on diagnosis, a service fee may apply, but general technical questions about any brand are always free.
