About Us

Blacktop Repair was founded out of necessity — built as a one‑stop shop for heavy‑duty truck and trailer repair, maintenance, and washouts. After years of waiting on outside providers, we created a solution focused on speed, quality, and keeping rigs moving without the downtime most shops create.

With over 30 years of combined experience in trucking and logistics, we know what it takes to keep equipment on the road. We don’t just service trucks — we run them ourselves. That firsthand experience drives how we prioritize urgency, margins, and the real‑world challenges drivers face every day.

Our mission is simple: support internal fleet operations and outside customers with reliable, flexible, and honest service under one roof. From routine maintenance to tires, brakes, DOT inspections, and trailer washouts, we make every visit fast, fair, and productive.

Time is money in this industry, and we treat it that way. We believe in straightforward communication, honest pricing, and building a culture that supports our employees, subcontractors, and customers alike.

At Blacktop Repair, we’re not just here to fix equipment — we’re here to help you run a safer, more efficient, and more profitable operation

Built for Drivers. Backed by Results.
