Frequently Asked Questions

We get it — hiring a deck builder is a big decision. That’s why we’ve answered the most common questions Maryland homeowners ask us before they choose Alliance Deck Builders.

Question 1: How long does it take to build a new deck?

Most projects take 1–2 weeks once we break ground. The timeline depends on size, materials, and permits. We give a clear timeline up front and stick to it.

Question 2: Do you help with permits and HOA approvals?

Yes. We handle all permitting with your city or county and can assist with HOA paperwork if needed — no red tape stress on your end.

Question 3: What’s the difference between wood and composite decking?

Wood is cost-effective and classic, while composite costs more upfront but requires less maintenance. We’ll help you choose what fits best.

Question 4: How do I know the quote won’t change later?

We believe in transparency. Your written estimate includes all costs. No surprise fees. No pushy upsells. Just what’s needed to do the job right.

Strong Foundations for a Long-Lasting Deck

Most homeowners focus on decking boards — but it's the framing beneath that determines how long your deck lasts. At Alliance Deck Builders of Maryland, we use code-compliant spacing, pressure-treated joists, and stainless hardware to ensure a rock-solid structure that holds up through Maryland weather and time.

  • Framing is built to meet and exceed local codes

  • We use high-grade, rot-resistant lumber

  • No shortcuts on joist spacing or ledger anchoring
