We pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!

"Ben Muck of A & M Landscaping turned our backyard into a sanctuary. It is now my favorite place to be, in or outside of my house! Whether for socializing, or recharging alone, Ben created spaces that are comfortable, functional, and beautiful. He was easy to work with, pleasant, informative, and professional, and delivered above and beyond all we had hoped for. Our backyard renovation was especially important to my husband and me, because this is our first house, and it was inheritance money from my grandparents that provided for the project. I told Ben that it was at their house as a child that I learned the joy of â visitingâ with loved ones outside. Ben designed a space Grandma and Grandpa would have loved, and I am so very grateful."

"Jeff came by to quote a basement upgrade going from bare walls and ending with a complete family room, bedroom and bath. He clearly understood the entire process and willingly provided valuable inputs/advice that enabled a better visualization of the space. He turned the quote around in a week and I would highly recommend him if you are looking for a quote to upgrade your basement. In the end we did not go with Truste Construction since the bid was outside our budget."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
