In Rennerdale, PA, home life can be steady and familiar, with stairs used again and again through the day. Good stair access is rarely loud; it simply works, day after day.
For many homes in Rennerdale, across Allegheny County, we look at the staircase layout (straight vs. curved) and keeping movement between floors easy over time so the setup fits cleanly.








These stair lift solutions are commonly installed in walk-up apartments and townhouses, and can be mounted on wooden, stone (including marble), or metal staircases, both indoors and outdoors.



Whether you're looking for a chair lift, vertical platform lift, or wheelchair lift, our indoor systems are available in multiple configurations and can be installed on nearly any staircase—straight or curved.
Depending on your home’s layout, the rails can be mounted to the wall or directly on the steps, ensuring minimal impact on the structure of single-family homes, apartment buildings, or public facilities.
Homes combine split-level interiors, basement connections, and full stair flights shaped by hillsides and older layouts, as part of everyday movement between levels.
Our outdoor stair lift systems are built from weather-resistant materials and feature protective coatings for long-term durability.
The sealed drive units offer safe and reliable performance in all weather conditions.
Just like their indoor counterparts, the platforms are foldable, saving space when not in use.
Exterior entry steps connect stoops, porches, and grade changes from sidewalks or driveways with exposed, weather-affected approaches, where reliable daily access matters.






By choosing a used stair lift, you can save up to 60% compared to buying new.
The actual savings depend on the custom rail system required.
For staircases over 16 feet or with curves, custom-fabricated rails may be necessary, which could involve additional one-time costs.

The same cost-saving benefits apply to rentals:
Thanks to simple installations and short rental periods, stair lift leasing is a smart way to stay mobile without long-term commitment.
Tip: Some funding programs or subsidies may also cover stair lift rentals.

Platform lifts follow the principle of industrial lifting platforms and freight elevators.
These lifts include a non-slip coated platform that can be accessed using a walker or wheelchair.
Many models feature foldable platforms to save space when not in use.
Vertical platform lifts are ideal for small elevation changes between 32" and 80" (80–200 cm).
Thanks to their weather-resistant stainless steel or aluminum design and sealed drive electronics, they are commonly used outdoors.
These lifts require no rails and take up minimal space — making them both cost-effective and efficient.
Also known as wheelchair elevators, they move vertically next to the staircase.
A ceiling lift is installed along an overhead track, making it a highly space-saving solution with no need for floor-mounted structures.
These systems are available both with and without seating, offering options for wheelchair users or patients needing seated transfer.
The chair lift is the classic stair lift solution and often one of the most affordable options.
It’s perfect for individuals who don’t require a wheelchair full-time, but still need assistance moving safely between floors.
Standing lifts are a type of platform lift featuring sturdy handrails and an anti-slip standing platform.
They’re ideal for users with walkers or rollators who may not be comfortable sitting but still need vertical mobility support.
The lean-on lift is a hybrid between a chair lift and a standing lift.
It is especially suitable for users with knee or hip issues, since it allows a supported posture where the legs remain neither fully straight nor bent.
The term "wheelchair lift" is used to describe any type of lift that allows direct access while staying in a wheelchair.
Stairlifter USA offers both platform lifts and vertical lifts (VPLs) designed for wheelchair users.
Key difference: Platform lifts run along a staircase rail, while vertical lifts move straight up next to the stairs — no rails needed.
Choose a stair lift model based on your individual needs.
For example, wheelchair users typically require a drivable platform lift that supports full accessibility.
Not every stair lift fits every staircase.
In narrow stairways, a lift with a folding seat or compact platform may be the smartest solution.
If physical or structural conditions limit your options, the cost of purchasing a stair lift can be quite high.
Check if financial assistance or rental options are available to reduce the expense.
