The North Star Companies, LLC, is the premier contracting company in MD. We pride ourselves on delivering a quality service, at an affordable price, with the customer's best interests at heart.

"We have used The North Star Companies for several jobs in the past, with the most recent being the largest. We hired them do a complete renovation of our home in Severn. The job grew larger as demo began and turned into a job requiring the rebuild of exterior walls, demo of concrete slabs - basically the house had to be rebuilt from the ground up. All new plumbing, electric, framing, windows, siding, roof, etc. I have known Chris for 20+ years and was confident that our forever home would be solid and done right. We had a few hiccups throughout the process - as this was done during Covid, so there were supply issues, delays and so forth, but Chris and his guys did an amazing job. We couldn't be happier and are continuously getting compliments on our beautiful home. Chris has been and will continue to be our go-to for any construction needs for us and our family and friends."

At R O Hutchinson LLC, we specialize in transforming spaces to meet your unique needs. Based in Upper Marlboro, MD, our expert team focuses on premier residential Remodeling. We excel in kitchen and bathroom remodels, flooring installations, and comprehensive basement renovations. With a strong reputation built on service, safety, and quality, RO Hutchinson LLC places utmost priority on customer satisfaction and delivering excellent workmanship from start to completion of every project. Our commitment is to understand the needs and expectations of our customers, communicate professionally, and get the job done right the first time.

"Our family home has always been clean and functional but after thirty years it had become more a picture postcard from the 1980’s than the warm inviting image we had in our mind. It was obviously time to update. Unfortunately, after talking with numerous contractors, it seemed we would have to reduce our expectations or spend more than we had budgeted to afford remodeling our “dining room, living room, kitchen” (and eventually bathrooms too!) project. While pondering our next move a family friend told us they recently had Rohan remodel their kitchen/living space and it looked great and was, they thought, affordable. After seeing for ourselves the quality of workmanship, the improvements to ‘flow and functionality’ and the overall aesthetic appeal, we decided to give Rohan a call. Boy are we glad we did! Upon meeting Rohan for the first time we were shown the same optimism, knowledge through experience, flexibility of thought and dedication to quality that would continue straight through to the end of our multi-week project. His proposal/estimate covered all our wants and needs while fitting within our budget. The job was a total re-do and from floors to walls to counters to cabinets to plumbing to electrics and all were handled by Rohan and his team with time honed skill. The work was done in a timely fashion without ever leaving us wondering where people were or what they were going to be doing each step of the way. Every eventual ‘architectural surprise’ was met with candor, budgeted creativity and a hearty “no problem!” In the end our home was transformed ergonomically, aesthetically and affordably into a beautiful space where family and friends gather in happiness and in harmony with their surroundings. If you are considering remodeling your home we urge you to give Rohan a call. Boy will you be glad you did! "

OVER 100 YEARS COMBINED EXPERIENCE AS YOU PATIO AND HARDSCAPE EXPERTS! SBC Outdoor Services was founded in 2015 by Brad Crist. Brad had over 15 years of experience in the industry and wanted to create a landscaping company that could hold true to the concept of “quality landscaping.” Ever since then we've been constantly growing as a high-end hardscape, landscape design, and commercial maintenance business. Over the course of our existence, we've earned a great reputation for quality service and we aim to not just maintain our reputation for excellence but to constantly improve it. That's why we only hire the best of the best. Our management team alone has over 30 years of experience in the industry and members of management used to maintain the White House. The rest of our team is similarly qualified and has over 100 years of combined experience. At SBC Outdoor Services we believe that landscaping is an art, not just a skill. We not only teach our employees proper installation methods but also encourage them to take initiative and to completely pour their imagination and skill into their work. Our design and installation divisions make sure that the product will be very functional as well as attractive while our maintenance division employees take great pride in the ongoing beauty of your property.

You’ll get both in S&J. As a family owned and operated business located in Howard County, MD we have been helping homeowners in all of Howard County MD, parts of Carroll County, Baltimore County and Northern Anne Arundel County Maryland and surrounding areas with their home improvement needs for over 20 years.

"Jerry was friendly, efficient, straight-talking, and didn't try to upsell us. We didn't need (or want) a lot of design input and had a strong sense for the types of tile and fixtures we wanted. Many of the other contractors who came to give quotes pushed design services or strongly encouraged us to purchase low-quality tile/fixtures through their suppliers, but this wasn't the case with S & J. Elias was fantastic--he helped confirm our tiles and fixtures were appropriate before we finalized our purchases, and we appreciated his attention to detail throughout the process."

FAQs for addition to existing structure building service projects in Oxon Hill, MD

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
