How Much Does a Deck Cost in Maryland? (2026 Price Guide)

It's the first question almost every homeowner asks, and the honest answer is: it depends. Deck cost varies with size, material, height, railing, and the features you choose. Below we've laid out real 2026 price ranges for Maryland, including cost per square foot, what drives the number up or down, and sample project totals. We've been pricing and building decks across the Baltimore area since 1986, so these figures reflect what local homeowners actually pay.

Deck cost per square foot by material

Material is the single biggest factor. Here's what to expect, installed, for 2026:

These ranges include materials and professional installation of a standard deck. Premium railings, complex shapes, tall elevations, and add-ons push you toward the upper end. Want to understand the trade-offs? See our guide to composite vs. wood vs. PVC decking.

What drives the price up or down

Size

Bigger decks cost more in total but often less per square foot, since fixed costs spread across more area. Doubling the size rarely doubles the price.

Height off the ground

A ground-level deck is far cheaper than a second-story deck. Raised decks need deeper footings, taller posts, more framing, and often stairs and code-compliant guardrails.

Railing

Railing is one of the most underestimated line items. Pressure-treated rail is cheapest; vinyl, composite, aluminum, and cable railing cost more but look better and last longer. Explore options on our railing products page.

Stairs, foundation & site conditions

Each run of stairs adds cost, especially on raised decks. Sloped yards, rocky soil, poor drainage, or hard-to-reach backyards all add labor. A flat, accessible yard keeps costs down.

Add-ons

Features like integrated lighting, built-in benches, pergolas, and under-deck drainage systems add cost but a lot of enjoyment — and they're cheapest to install during the original build.

The real cost question: upfront vs. lifetime

Pressure-treated wood wins on day one but costs more over time. Plan on cleaning, sealing, and staining every one to three years, plus board replacement as it weathers. Over 25 years, a "cheap" wood deck can cost more than a composite one. Composite and PVC cost more upfront but need only occasional washing — so many Maryland homeowners find them the better long-term value.

Ranges are estimates for budgeting only. Your exact price depends on your site, design, and selections — the only way to know for sure is a free on-site measurement and quote.

Can you finance a deck?

Yes. Many homeowners spread the investment over low monthly payments rather than paying all at once. We offer flexible financing, including options that get you into your new outdoor space now and pay for it over time.

Frequently asked questions

How much does a 12x12 deck cost in Maryland?

A 12×12 (144 sq ft) deck typically runs about $5,000–$9,000 in pressure-treated wood and $7,000–$11,000 in composite, installed, depending on height and railing.

Is composite decking worth the extra cost?

For most Maryland homeowners, yes. The higher upfront price is offset by decades of near-zero maintenance — no annual staining — and a longer lifespan in our humid, freeze-thaw climate.

Why are deck estimates so different from company to company?

Quotes vary based on material grade, framing quality, railing type, and whether permits and cleanup are included. Always compare what's actually in the quote, not just the bottom line.

Does a new deck add value to my home?

Yes — decks consistently return a strong share of their cost at resale. See our guide on whether a deck adds value.
