Decks & Porches

Decks and porches are the bridge between the house and the yard. We build them like that matters — proper footings, code-compliant framing, hidden fasteners, and finishes that hold up to NoVA’s wet springs, hot summers, and freezing winters. Every project is permitted, inspected, and built by our own crew.

Frequently Asked Questions

Q: Composite vs. wood deck in Northern Virginia?
A: Composite wins for low-maintenance and longevity in NoVA’s humidity, but premium hardwoods like IPE still beat it for natural beauty if you’re willing to oil annually.
A: Yes — virtually every attached deck in Loudoun, Fairfax, and PW County requires a permit and inspection. We pull and manage all of it.
A: A standard composite deck takes 1–2 weeks of construction once permits clear. Screened porches add 1–2 weeks.
A: Sometimes — depends on footing depth, size, and age. We’ll inspect before we quote.
A: Yes. Manufacturer warranties on composite (often 25–50 years) plus our own workmanship warranty.
