Decks we build
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

- 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.

Do you build composite decks and front porches?
Yes. Composite decks are our most requested deck type, and we also rebuild and build new front porches on row homes, twins and single homes.
What types of decks do you build in Philadelphia?
Wood decks, composite decks, elevated and multi-level decks, and rooftop decks, from a classic natural wood look to a low-maintenance composite finish.
How long does it take to build a deck?
Most decks take about 2 to 4 weeks to build, depending on size, materials and design. Permit review time is separate.
Do I need a permit to build a deck in Philadelphia?
Yes, most deck projects require a permit from Philadelphia L&I. MatrixGC handles the drawings and permits and makes sure the deck meets zoning and building codes.
Is composite decking better than wood?
Composite lasts longer with less maintenance and resists rot and fading, but costs more up front. Wood costs less to start but needs regular sealing. We help you choose what fits your budget and use.
Can you build a roof deck on my rowhome?
