Composite vs. wood decking

  • Composite: resists rot, splintering and fading, needs no staining, costs more up front.
  • Pressure-treated wood: the lowest starting cost, needs regular sealing or staining.
  • Hardwood: a rich natural look and long life, at a higher material cost.

We help you choose based on budget, sun exposure and how much upkeep you want. Railings, lighting and stairs are all part of the design.

Permits and code

Most decks in Philadelphia need a building permit from L&I, and roof decks and elevated decks often need drawings and structural details. MatrixGC prepares the drawings, files the permit, and builds to the approved plans so your deck passes inspection.

How much does a deck cost? Every deck we build is custom, so price depends on size, height, materials and railings. Call (215) 501-7566 for a free rough estimate.

What a deck costs in Philadelphia

Every deck is custom, so your written estimate after a free site visit is what counts. These are typical installed ranges we see in Philadelphia and South Jersey:

  • Pressure-treated wood deck: about $35 to $60 per square foot.
  • Composite deck (Trex, TimberTech and similar): about $55 to $100 per square foot.
  • Front porch rebuild: about $15,000 to $45,000, depending on size, roof and masonry.
  • Rowhome roof deck: often $40,000 to $100,000 or more, because of structure, roofing, access and permits.

What changes the price

  • Size, height and how many levels or stairs
  • Decking material and railing style (wood, composite, aluminum, cable)
  • Footings, framing and any structural work, especially on roofs
  • Permits, drawings and engineering
  • Lighting, privacy walls, pergolas and built-ins

Composite deck builder

Composite decking is our most requested material in Philadelphia. It does not rot or splinter, it holds its color, and it never needs staining. We install the major composite brands with hidden fasteners, proper joist spacing and the right ventilation, so the deck stays flat and the warranty stays valid.

Front porch builders

We rebuild and build new front porches on Philadelphia row homes, twins and singles: framing, decking, steps, columns, railings and porch roofs. Porches facing the street often need permit drawings and must meet code for guards and stairs, and we handle that for you.

Roof decks and pilot houses

A roof deck turns an unused Philly rooftop into outdoor space. Most roof decks need structural review, a new roof membrane under the deck and a code-compliant way up, often a pilot house. Read our guide to pilot houses and roof deck benefits, and see how the Philadelphia EZ deck permit works for simpler ground-level decks.

Deck builders across Philadelphia neighborhoods

We build decks all over the city. For example, roof decks are popular on rowhomes in Fishtown and Kensington, Center City and South Philly, where yards are small. In contrast, rear and elevated decks are more common in Manayunk and Roxborough, Northeast Philadelphia, Germantown and Mount Airy and West Philadelphia.

Either way, we check the zoning and the structure first, and then we pull the permits. See how the Philadelphia EZ deck permit works.

How to choose the best deck builder near you

Whether you want a composite deck, a custom roof deck, or a new front or back porch, the right builder matters more than the material. Before you sign with any deck builder in Philadelphia, check these:

  • A Philadelphia contractor license. Ours is license #43984. You can look up any contractor's license in a minute.
  • Permits pulled by the builder. Most decks and porches need a permit. We file it, including the EZ deck permit when it applies.
  • A written, itemized estimate. Framing, decking, railings and stairs listed separately, so you can compare builders line by line.
  • Experience with row homes. Back porches and roof decks on attached homes need care with party walls, drainage and the neighbors' roofs.
