Our Decks & Porches Process

Decks & Porches Cost in Maryland

Deck and porch costs in Anne Arundel and Howard County typically run $15,000–$25,000 for a basic 12×16 pressure-treated wood deck, $25,000–$50,000 for a mid-range composite deck, and $40,000–$80,000+ for larger composite builds with multi-level designs, pergolas, or built-in features.

How Long Does Decks & Porches Take?

A new deck takes 1–3 weeks of on-site construction once the permit is in hand; county deck permits typically issue in 1–2 weeks in Anne Arundel County and 2–4 weeks in Howard County. Deck replacements run 2–3 weeks from demolition through final inspection. Screened porches are bigger projects: plan for 3–6 weeks of active construction and 8–16 weeks from first conversation to finished porch including permitting and material lead times.

Decks & Porches in Maryland: What to Know

Maryland humidity and freeze-thaw cycles make material choice and structural detail more consequential here than in drier climates. Pressure-treated wood costs less upfront but warps, splinters, and gray within 3–5 years without annual sealing — most homeowners regret it. Composite (Trex, TimberTech, Fiberon) costs 40–70% more at install but carries 25–50 year warranties and skips annual maintenance. Footings need 42″ depth to clear the Maryland frost line, and ledger boards must be flashed properly to keep water out of the rim joist. Anne Arundel and Howard County both require permits with three inspections (footings, framing, final) for new construction.

Deck Builder Serving Anne Arundel County

PRG Home Improvement is headquartered in Gambrills, in the middle of Anne Arundel County — most of our deck and porch builds happen within a 20-minute drive of our shop. We prepare permit-ready plans for the Anne Arundel County Office of Inspections and Permits showing footings, framing, ledger attachment, and railing details, then manage the footing, framing, and final inspections so the project never stalls waiting on the county.

Local specifics matter here. Planned communities like Crofton require architectural review approval for decks and porches before any county permit is issued, and HOA neighborhoods in Severna Park such as Shipley’s Choice have their own design standards — we prepare those submissions alongside the permit application so both reviews run at once. In newer Odenton communities like Piney Orchard and Seven Oaks, most builder-grade homes were delivered without any deck at all, and adding one is typically the first major upgrade owners make. Waterfront and near-water lots in the Chesapeake Bay Critical Area along the Severn, South, and Magothy rivers get extra county review, and we design within those constraints.

Deck Builder Serving Howard County

In Howard County, deck permits go through the Department of Inspections, Licenses and Permits (DILP), and in Columbia nearly every village also requires an architectural committee application through the Columbia Association or the village board. We submit HOA-ready drawings in parallel with the DILP application so the reviews don’t stack up sequentially. A large share of our Howard County work is replacing failing 1980s pressure-treated decks in Columbia’s original villages with composite rebuilds on new code-compliant framing.

One recent Columbia project — a composite deck and hardscaped patio at a townhouse — required Howard County inspections plus documentation for two separate HOAs. The homeowner’s Google review afterward: “Anton … is very responsive, kept us updated on progress, took care of all Howard County inspections, provided all docs for our two HOAs, and finished on time! … There were no surprises and they completed everything in the original budget.”

Deck & Porch Projects We Build Most Often

Composite deck replacement: tearing off a failing 15–30-year-old pressure-treated deck and rebuilding with Trex, TimberTech, or Fiberon on properly flashed, code-compliant framing — the most common deck project in Columbia, Millersville, and Severna Park. New decks for builder-grade homes: NVHomes and Ryan Homes buyers in Odenton, Gambrills, and Fulton typically get no deck from the builder; we design and build to match the home and the HOA’s standards. Screened porches and three-season rooms: on the larger lots in Gambrills, Crownsville, and Davidsonville, a roofed screened porch often makes more sense than an open deck — see our screened porch cost guide for real 2026 pricing. Structural repair: ledger, post, and beam repairs that bring an existing deck back to code without a full rebuild.

Why Homeowners Choose PRG Over Deck Franchises

The big deck-franchise operations in this market run showrooms, sales teams, and project managers — overhead that shows up in the quote. PRG is an owner-operated, MHIC-licensed contractor: the person who quotes your deck is the person who builds it. On identical scopes we typically come in 15–25% below design-build firm pricing, and every build is permitted and inspected — footings at 42″ below grade for the Maryland frost line, flashed ledgers, and hardware-connected posts and beams, never nailed. Read our post-to-beam connection guide to see the structural detail we put into framing, or call 443-856-5379 for a free on-site design consultation.

Decks & Porches FAQ

How much does it cost to build a deck in Maryland?

Deck costs in Anne Arundel and Howard County range from $15,000-$25,000 for a basic pressure-treated wood deck to $40,000-$80,000+ for larger composite decks with premium features. See our full Maryland deck building cost breakdown.

What's the difference between wood and composite decking?

Pressure-treated wood costs less upfront ($15-$25/sq ft) but requires annual maintenance and lasts 15-20 years. Composite ($30-$50/sq ft) is maintenance-free and lasts 25-30+ years. Read our composite vs. wood decking comparison.

Do I need a permit to build a deck in Anne Arundel County?

Yes. Anne Arundel County requires building permits for new deck construction. You'll need to submit plans showing deck size, height, attachment method, footing locations, and railing details. Inspections are required for footings, framing, and final completion. We handle the entire permit process including plan preparation and inspection scheduling.

What size deck do I need?

Consider your intended use. For a dining table and 6 chairs, plan at least 12x12 feet. Add a grill area plus seating: 14x16 feet or larger. Hot tubs need additional structural support and typically a dedicated 10x10 section. For multiple zones (dining, lounging, grilling), 400-600 square feet provides comfortable space.

Can you add a roof or pergola to my deck?

Yes. Options include pergolas (partial shade, architectural interest), solid roof extensions matching your house, retractable awnings, and screen enclosures. Each requires proper structural support—we often upgrade deck framing to handle additional loads. Covered spaces require permits. We design covered areas that complement your home's architecture.
