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."

We ensure a high quality finished product with flexible and attentive service at a competitive price. We pride ourselves on having the ability to make our clients visions come to life with great design ideas and execution. Showrooms: Chantilly, (VA) (703) 657-0997 and Gaithersburg, (MD)

"It is my pleasure to review DMV kitchen and bath. They did an outstanding job from conception through to the last details in finishing an extensive series of renovations - complete kitchen tear-down and renovation, master bathroom and closet teardown and renovation, two bathroom complete retiling/renovation, building two new rooms out of a very large basement, and replacing two forced air HVAC systems - they managed all aspects including proper construction permits. They did high-quality work at a very good price. They did an outstanding job with the work, with high attention to detail. Their communication was very strong from beginning to finish, their initial plan recommendations were excellent, they made several recommendations to not only make the job better, but also make it more cost effective along the way. They were reliable and consistent, and very genuine, "real" people. I have to imagine there will be very high demand for their services. I can’t recommend highly enough. Very timely, excellent communication, quick and high-quality professional work at a competitive price."

"STAY AWAY!!!! This Company cancelled the initial estimate on me 3 times making me drive 90 minutes to the property each time. They finally showed and gave me the typical hard sell "if you sign the contract today..." They gave us a quote so far over market value we should have walked away. But we agreed because of the "70 year history in the industry" We thought we were buying a service from a company with integrity. They took an immediate $18K deposit on a $55K project. I know, shame on me for agreeing to such an amount. We knew we were over spending, but... One month later, they simply cancelled the contract without explanation and without any work on the project. This contract was binding on us but, in their words, was not binding on them because "there's a clause in the fine print that allows them to cancel" THEY STILL HAVE OUR MONEY and I STILL NEED A ROOF Stay away from this company. No integrity No responsibility Unreliable Over priced Will take your money and keep it"
