Locally owned business with over 12 years of experience. Custom Paver Patios, walkways, retaining walls, and driveways. We also offer full clean up landscaping, hardscaping, and stone work. Passionate about serving our local community and continuing to deliver great customer service. Feel free to call or text with questions regarding your projects. Look forward to working with you on all your home endeavors.

"M&L Landscaping Construction is absolutely incredible! You will not regret hiring Leo and his team for your project. I first hired Leo for one job, and after seeing the quality, precision, and care in his work, I immediately brought him back for a second. The first project included pavers, a retaining wall with built-in seating, a garden bed, patio/paver installation, fence installation, and a composite deck with stairs. The second project was for my rental property and involved an insurance claim to repair the facade of the house. That work included installing stone veneers on the front of my home, constructing a new deck with a roof, building a stone wall with fencing, and completing a blacktop driveway. What truly sets M&L apart is not just the beauty and craftsmanship of their work, but the professionalism, organization, and integrity behind it. Leo’s team is respectful of your property, punctual, and incredibly hardworking. They take pride in what they do and it shows in every detail—from layout precision to cleanup after completion. Equally impressive is how Leo manages the business side of things. He’s communicative, transparent, and extremely reliable—qualities that are rare to find in the contracting world. He provides clear timelines, fair pricing, and proactive updates, so you always know where things stand. Having worked with many contractors over the years, I can confidently say that M&L Landscaping Construction is top-notch from start to finish. I was so impressed that I even referred my parents for their driveway paver installation—and, just as expected, it came out beautiful. If you’re looking for a trustworthy, skilled, and professional landscaping and construction team, hire M&L Landscaping Construction. You’ll be glad you did!"

FAQs for addition to existing structure building service projects in Dover, DE

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
