Frequently Asked Questions

We know starting a deck project comes with questions — and we’re here to make the process simple, clear, and stress-free. Below are answers to the most common questions Gaithersburg homeowners ask us.

Question 1: How do you start the deck-building process?

We begin with a quick consultation to learn about your goals, budget, and style preferences. From there, we design a custom plan for your space, review material options, and provide a clear estimate before any work begins.

Question 2: What materials do you offer for new decks?

We build using premium composite decking, pressure-treated lumber, cedar, and other high-quality materials suited for Maryland weather. We’ll help you choose the best material based on maintenance needs, appearance, and long-term durability.

Question 3: When can I expect my project to start after approval?

Most Gaithersburg projects begin within a few weeks after design approval and permitting. Seasonal availability varies, but we always communicate timelines clearly so you know exactly what to expect.

Question 4: What if I’m unsure what type of deck I need?

No problem — that’s what we’re here for. Our team will walk through your yard, discuss your lifestyle, and recommend designs that fit your home, budget, and long-term needs. Whether simple or fully custom, we’ll guide you every step of the way.
