FAQ
Stair parts questions, answered
Do I need to rebuild my stairs to remodel them?
Usually not. Most remodels keep the existing structure and replace treads, balusters, newel posts and handrail.
How do I know which parts I need?
Send a photo of your staircase and the number of steps. We will list every part so nothing is missing.
Do you sell to contractors?
Yes. We work with homeowners and contractors alike. Call to talk about project orders.
How fast is delivery?
Most items are delivered fast. Select items, such as standard-size treads and common balusters, can arrive next or same day.
Do you deliver for free?
Yes, on orders $99+ to NJ, NY, PA, CT and DE. Other states ship at real shipping cost, shown at checkout.
Do you offer installation?
No. We specialize in stair parts only, so prices stay sharp and delivery stays fast. Our parts work with any contractor or experienced DIYer, and we are happy to answer fit and sizing questions.
