Our License

Choosing a contractor who is unlicensed leaves you open to a variety of problems, not the least of which that there is no governing body ensuring that contractor has completed all of his or her requirements.

Many times, unlicensed contractors are able to “cut corners” and provide a more shoddy workmanship – leaving your home vulnerable and your money wasted.

ALCO is one of the first companies licensed in the State of Maryland, and we hold active licenses in Virginia, Maryland & Washington D.C.
