Frequently Asked Questions
At Mainline Paving & Masonry, we understand that investing in your property’s exterior is a significant decision that requires clear information and professional guidance. Below, we have compiled a comprehensive guide to our most common inquiries to help you understand our high standards and specialized project workflows.
How soon can I drive my car onto a newly paved asphalt driveway?
We understand that you are eager to get back to your normal routine, but patience is vital for a long-lasting surface. Once we complete the installation of your new driveway, we require that you keep all vehicles off the fresh asphalt for at least 24 hours. If our team is working during a period of extreme Maryland summer heat, we may advise you to wait a full 48 hours. Unlike some other asphalt companies in Gaithersburg, MD, we prioritize the curing process to prevent premature scuffing or power steering divots.
What is the standard thickness you use for a residential driveway?
When we install a new residential driveway, we follow strict specifications to ensure the surface can handle the weight of your vehicles without cracking. Our standard procedure involves laying 2 to 3 inches of compacted asphalt over a solid granular base that is 6 to 8 inches deep. This foundation is what separates the elite asphalt companies in Gaithersburg, MD from those who cut corners. By ensuring the sub-base is properly prepared and the asphalt is applied at the correct thickness, we provide a surface that remains smooth and functional for years.
What kind of materials do you offer for new patio installations?
We take great pride in our ability to customize outdoor living spaces to match our clients' unique visions. For new patios and walkways, we work with a wide range of high-quality materials, including brick pavers, natural stone, and traditional concrete. Whether you want a rustic stone look for a backyard fire pit or a sleek, modern paver design for a large entertaining area, our masons have the precision to bring that idea to life. We focus on creating "Quality Surfaces" that enhance your property value. Unlike many standard asphalt companies in Gaithersburg, MD, our dual expertise in both paving and masonry allows us to create complex, multi-textured landscapes that look cohesive and professional.
Will the owner be present to oversee the work on my property?
Absolutely. One of the core pillars of our family-owned business is that the owner supervises every single project we take on. We do not believe in disappearing once the contract is signed; we stay involved from the initial free estimate until the final walkthrough. This hands-on approach ensures that our high standards of craftsmanship are maintained and that any questions you have during the construction process are answered immediately. While some larger asphalt companies in Gaithersburg, MD might send a rotating crew of subcontractors, we provide a consistent, owner-led team dedicated to your satisfaction.
How do I get a quote for a new asphalt commercial parking lot?
Getting started with us is simple and transparent. We offer free on-site estimates for all commercial and residential projects, including large-scale parking lot installations and asphalt overlays. You can contact us via our main office line or our mobile number to schedule a time that works for you, or you can even request an estimate through our online system. We provide competitive pricing and clearly outline the scope of work so there are no surprises.
