25 Years Under
Other People's Decks.
A family business in Lawrenceville. Our own crews do the work on your property, start to finish.
You Already Own This Space. We Make It Usable.
Under-Deck General LLC is a family-owned exterior contractor based in Lawrenceville, Georgia, with 25+ years of experience. Our core expertise is transforming the wasted space beneath second-story decks into clean, dry, functional outdoor living areas.
We install professional underdeck ceiling systems that capture rainwater and channel it away, so a muddy, unusable under-deck area becomes a dry patio, outdoor kitchen, or entertainment space.
We also install traditional gutters, gutter guards, soffit and fascia, the full exterior drainage package that protects your home from water damage.
