Why Choose Montocon General Contractor
One crew, nine trades, and a finish you would be happy to put your own name on.
One Crew, Whole Project
Additions, basements, decks, roofing, windows, siding, painting, drywall and millwork under one roof — so nothing falls between two contractors and one team owns the result.
20+ Years of Hands-On Experience
Montocon is led by a contractor with more than twenty years of hands-on experience in the DMV. That experience is the owner's, earned on job sites across Maryland, Virginia and D.C.
Insured
The business carries insurance and comes with its own equipment, so your project is covered and we are not renting a saw on day one.
Honest Pricing
Free written estimates with no surprises — the price is agreed before any work begins, and change orders are discussed, not discovered.
English & Spanish
The owner works in both languages, so you deal directly with the person running your job, in the language you would rather use.
Respect for Your Home
We protect what's staying, keep the site clean while we work, and leave it tidy before we call the job finished.
Areas We Serve
We work across the DMV — Montgomery County, Arlington, Alexandria, McLean, Fairfax County and more.
