“Our first bid to replace 3 exterior doors from a well-known company was $22,000! We were referred to Builders Surplus and Jim Morrison gave us wonderful service — he even went above and beyond to get the exact sidelights I wanted. The doors came in perfect condition. After purchase and installation we spent $10,500. What a savings, and superb quality!”

“Frustrated with the big box stores, I tried Builders Surplus Louisville for a full-view door in a custom size at a fair price. Working with Jim, I got exactly what I wanted in 3 weeks, and Daniel did a top-notch install. I came back later and Jim helped me order the right Andersen storm door too. Very satisfied with the whole experience.”

“In the middle of a snowstorm I realized I needed a door at the last minute. I called and spoke with Jessica — incredibly nice and helpful. She checked stock and gave me a price right away. I drove over the same day and the whole transaction was seamless. They had me loaded and paid in less than five minutes. Big shout-out to you all!”

Doors — Frequently Asked Questions
What’s the difference between a prehung door and a slab door?
A prehung door comes with the frame, hinges, and weatherstripping already attached — it’s the complete unit, ready to install into a rough opening. A slab door is just the door panel itself, without the frame. Prehung doors are the most common choice for replacements and new construction.
Do you carry 36×80 exterior doors in stock?
Yes — 36×80 is one of our most common exterior door sizes and we typically carry it in both steel and fiberglass in Louisville and Florence. Stock changes frequently, so call ahead or stop in to see what’s available today.
Do you carry 32×80 exterior doors?
Yes, 32×80 is a standard size we regularly carry in prehung exterior doors. It’s a common replacement size for older homes. Give us a call to confirm current availability at your nearest location.
What exterior door materials do you carry?
We carry both steel and fiberglass exterior entry doors. Steel doors are durable, affordable, and energy-efficient. Fiberglass doors offer a more realistic wood appearance, resist dents and rust, and are ideal for harsh weather climates. Our team can help you choose the right material for your home and budget.
Can I get my door installed by Builders Surplus?
Yes — we offer door installation services. Ask about installation when you visit or call us at 502-968-8858 (Louisville) or 859-261-3111 (Florence). We can pair you with an installer and help you plan the full project.
