Derek and team were a pleasure to work with. He was very responsive from the first call and came right out to provide an estimate. He is very knowledgeable and easy to work with. And he supervises all the onsite work that his great team does. They are very efficient and deliver great work very quickly. I would highly recommend Derek and team and would use them again for another driveway replacement job or any similar type work.

We hired Mainline team to repave our driveway and repair a sunken area, and they completely exceeded our expectations. The quality of their work is outstanding — the new pavement is smooth, even, and looks fantastic. The sunken section was fixed perfectly and you’d never know there was ever an issue. From start to finish, the whole experience was seamless. I’m genuinely impressed and would not hesitate to recommend them to anyone looking for top-notch paving work. Five stars without question! Thank you, Derek and your team!

Mainline Paving & Masonry did an outstanding job replacing our driveway. From start to finish, the process was seamless—they arrived in the morning and had everything completed by the afternoon. Derek and his team were highly skilled, efficient, and clearly take pride in their work. The quality of the finished driveway speaks for itself. If you’re looking for professionalism and top-notch results, I highly recommend them.

Derek was very meticulous with details, on point communication with the timelines of the project, listened to my ideas and provided his recommendations which helped in finally finishing the driveway for the house. Amazing experience with Derek and his team. Thank you again.

Our family recently hired Mainline Paving and Masonry to expand and repaved our driveway. We had wanted to complete this project for over a year. Because it was a long time coming, we made sure to do our homework before pulling the trigger. My husband and I compiled a list of 10 companies (based on online reviews and recommendations) to contact. Mainline really stood out during our initial conversations. After leaving messages with all ten companies, Mainline was the ONLY one to call me back within the day AND come over to understand and design the driveway we had been dreaming of renovating. NO other company did this. Several companies texted with me, or never called back, or called back with low energy attitudes. Derrick at Mainline gave us his cell phone number during our initial interaction and was always prompt to call/follow up. That was 10000% a selling point for us. Not to mention the care and time he took to meet with us, showed us how he handled business. He was clear, detailed and answered all of our questions. And although he wasn’t the cheapest option, we chose his team for all the factor to quality work. We were greatly impressed with the beautiful work him and his team did. Derrick was on site for much of the work, as well as messaged/called for sharing progress and updates. We did have a hiccup of an asphalt plant being down during day 2 of work, which delayed the completion one day. Luckily, this was no big deal for us. We appreciated things happen and we had built trust in Derrick along the way. We appreciated his direct communication and honesty. Again, we are very happy with the outcome! (Picture below) And so far our only comment of concern was the price difference between cash and credit card. We had not asked, but a service charge is added when using a card. Derrick was understanding and apologetic in not clearly articulating it, or honesty maybe I just forgot, but ultimately he worked with us to get checks payable and it wasn’t a big deal
