Mainline did a great job on our driveway that was in dire need of repair. Derek was fantastic to work with from the estimate through completion of the work. Highly recommend.

I hired the Mainline pavement for a big driveway paving project, and they did an incredibly clean and professional job. They clearly have the right resources—with their massive trucks and equipment, a crew of six worked together seamlessly and finished the job in no time. I am beyond satisfied. Having lived in this house for 38 years, I had a bad experience with a previous contractor who did sloppy work, but this team was a total breath of fresh air. 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. The work looks stunning and my husband and I are more than elated with our investment in a new and larger driveway.
Since it’s only been a week since installment, we can’t speak to how it looks/functions after it settles. Mainline has made it abundantly clear if ANYTHING comes up to give him a shout. And we know that’s not an empty promise. We shall come back to this review for an update when we can speak to the final product (~Oct 2026)
Thank you again so much Mainline for your care, professionalism, directness, and hard work. We would most certainly recommend them and use them again in the future.

Mainline paving and Masonry completed my driveway replacement very efficiently after I contacted them within 1 day. They finished the entire job in 3 hours, nice and clean. They stated it will last for several years and offered to call them if any issues, provided the personal cell. I had researched several companies before hiring them since they had 5 star rating by many and seems they kept their promise. They very professional, puntual and approachable.
Frequently Asked Questions About Mainline Paving & Masonry
What is the best surface for a driveway?
The most durable driveway surfaces include asphalt, concrete, and pavers. While many paving companies specialize in a single type of surface, Mainline Paving & Masonry offers expertise in all three and more. For personalized advice on the best surface for your specific needs, we encourage you to contact one of our experts. As trusted driveway contractors in Gaithersburg, MD, we're committed to providing you with the best solution.
How thick should driveway paving be?
The thickness of driveway paving varies based on several factors. For asphalt driveways, the National Asphalt Pavement Association recommends a combination of approximately 95% stone, sand, or gravel bound with asphalt cement. Residential driveways typically require two to three inches of asphalt, with three inches necessary for driveways that will bear large trucks or heavy equipment. A proper foundation is crucial, with six to eight inches of granular base aggregate underneath the asphalt. At Mainline Paving & Masonry, we ensure that every driveway we construct has the appropriate thickness and foundation for long-lasting durability.
Is it fine to pave over an existing driveway?
Paving over an existing driveway is possible, but it depends on the structural integrity of the current surface. At Mainline Paving & Masonry, we carefully assess each driveway to determine if an asphalt overlay is a suitable solution. When appropriate, our contractors apply a tack coat to the existing asphalt surface to ensure proper adhesion of the new layer. For more information about this process or to discuss your specific driveway needs, we invite you to contact us.
How long should you stay off the driveway after paving?
Generally, a newly paved driveway requires 24 hours before it can be used. However, during periods of very warm weather, we recommend waiting 48 hours as the asphalt surface cools more slowly. For more detailed information about our paving services and aftercare instructions, please don't hesitate to contact Mainline Paving & Masonry.
How does the weather affect the asphalt curing process?
Weather conditions significantly impact the asphalt curing process. Extreme cold can prevent proper binding of the asphalt, while extreme heat may cause new asphalt to melt, slough, or bruise, impeding proper curing. Many driveway and parking lot issues can be traced back to problems during the curing process. At Mainline Paving & Masonry, we carefully consider weather conditions to ensure optimal asphalt installation and curing.
