Let’s Build a Space You’ll Love For Years
Your home deserves an outdoor living area that’s comfortable, functional, and built to last. Whether you’re planning a full deck installation, a simple repair, or a complete outdoor transformation, our team delivers craftsmanship you can rely on. From material selection to final finishing touches, we make the process simple, stress-free, and tailored to your vision.
We understand that starting a deck project can feel overwhelming, so we’ve answered some of the most common questions homeowners in College Park ask us.
The process begins with a free on-site or virtual consultation. We discuss your goals, measure your space, review material options, and provide a detailed estimate. Once approved, we handle design, permits, scheduling, and construction from start to finish.
We build with premium composite decking, pressure-treated lumber, cedar, PVC, and hardwood options. Our team helps you choose the material that best fits your budget, maintenance preferences, and the Maryland climate.
Most projects begin within 1–3 weeks after approval, depending on design complexity and permitting. Once construction starts, standard decks are typically completed in 3–7 days, while larger or multi-level builds may take longer.
No worries — we’re here to help. Our designers provide layout recommendations, 3D visuals, and material comparisons so you can feel confident about your choices. We guide you through every step to ensure the final design fits your home and lifestyle perfectly.
