Deck & Screened Porch Builder in Arnold — Broadneck Peninsula

Arnold decks we build are spread across the Broadneck Peninsula — mid-century homes near the Magothy River, Cape St. Claire colonials and Cape Cods, and the established 1970s–80s neighborhoods like Green Haven and Cresston Park where larger lots leave real room to build. Many of these homes never had outdoor living space built in, and the aging pressure-treated decks that were added later are often past their useful life. Proximity to the water shapes material choices here: humidity and salt air are hard on wood, so composite is the default recommendation. Waterfront-adjacent lots near the Magothy may fall in the Chesapeake Bay Critical Area — we flag that during the estimate. MHIC #113057.

Screened Porch Builder in Arnold, MD

Screened porches are one of the most-requested outdoor projects we build in Arnold. This close to the Magothy, humidity and evening insects shorten the season on an open deck — a screened porch off the kitchen or family room keeps the space usable from April through October. We design the porch roof to tie into the existing eave or frame a matching gable so the structure reads as original construction on Arnold's mid-century ranchers and Cape St. Claire colonials, not a bolt-on.

A new screened porch in Arnold runs $22,000–$45,000, with most projects landing around $32,000 for a 200–300 sq ft porch with pressure-treated framing, a shed or gable roof, and quality screen and door hardware. Screening in an existing covered porch costs far less — typically $4,000–$10,000. The big cost drivers are the roof structure, a raised deck frame versus a slab base, and electrical (ceiling fan, wet-rated recessed lights, outlets). Anne Arundel County permit fees add $150–$500 for the building permit plus $50–$150 for the electrical sub-permit.

Every PRG porch uses Super Screen 17/14 vinyl-coated polyester mesh with aluminum-framed screen doors — not the builder-grade fiberglass that goes brittle and sags within a few years. For waterfront-adjacent properties where no-see-ums are the real nuisance, we install Super Screen's tighter 20/20 mesh. Framing meets current IRC requirements, footings go to frost depth, and we manage the Anne Arundel County permit and all three inspections (footings, framing, final). MHIC #113057.

How Does PRG Handle Decks & Porches Projects in Arnold?

In-home consultation to walk the lot, measure, identify property line and setback constraints, and check whether the lot falls in the Critical Area. We produce a permit-ready design with footing details, beam and joist specs, and railing compliance. After contract, the Anne Arundel County permit is filed (1–2 weeks for standard residential decks; longer for Critical Area lots). Construction sequence: footings to frost line (30"), framing, county framing inspection, decking, railings, stairs, and final inspection. Standard 14x18 composite deck: 2–3 weeks active. Larger builds with built-ins: 4–6 weeks.

Why Do Arnold Homeowners Choose PRG?

• Composite decking expertise (Trex, TimberTech, Fiberon) — we recommend composite over pressure-treated for nearly every Broadneck Peninsula build because of humidity and salt-air exposure near the Magothy.
• Larger-lot design experience — Arnold's established 1970s–80s neighborhoods leave room for full-size and multi-level decks, and we design around the lot rather than dropping a stock platform off the back door.
• Post-to-beam connections done correctly: beam bears on top of the post with Simpson post caps, not sandwiched on bolts. Code-compliant and structurally sound.
• MHIC #113057, fully insured. Anne Arundel County permitting managed start to finish, including Critical Area review when a lot requires it.

What decking material holds up best near the Magothy River?

Composite (Trex, TimberTech, Fiberon) is the standard recommendation for Broadneck Peninsula homes — it handles humidity and salt exposure better than pressure-treated lumber and never needs staining or sealing. Pressure-treated wood this close to the water tends to gray, crack, and demand annual maintenance within a few years. We also use corrosion-resistant fasteners on waterfront-adjacent builds.

Roof structure, a raised deck frame versus a slab base, screen system quality, and electrical scope drive the variance.
