A local crew,
seventeen years on.
Nelson Nieves founded NN Construction in 2009 with one truck and a short list of roofing clients. Today the shop runs twelve full-time tradespeople across framing, finish, and roofing, serving Montgomery County, DC, and Northern Virginia.
- Integrity.Written estimates, signed change orders, receipts on request.
- Innovation.Standing-seam details, engineered flashing, modern building-science — applied to old houses.
- Craftsmanship.Tight miters. Consistent reveal. Plumb to the foundation.
- Durability.Built to stand longer than the warranty.
We named the four pillars — Quality, Consultation, Timely Completion, Customer Satisfaction — because they are the complaints we heard most often about other contractors.
Most of our work starts as a referral. The second-most starts as a rescue from whoever was on the job first. We do not love taking over half-finished projects, but we've stopped being surprised by them.
What we promise: we show up. We price the job honestly. We write the change order before we swing the hammer. We stand behind the work for twenty-five years. It is a short list — and almost nobody keeps it.

The people on site.
A twelve-person shop. Three leads, plus tradespeople in framing, finish carpentry, and roofing.
Words from the sites we've finished.
“They showed up on the days they said they would, for the number they quoted. After two other contractors ghosted us, that alone was a revelation. The work itself is beautiful.”
