Main Line Deck Builder FAQ

Who is the best deck builder in the Main Line, PA?

How much does it cost to build a deck in the Main Line?

Most the Main Line decks run from about $20,000 for a straightforward composite deck to $90,000+ for a large multi-level deck with built-ins — Main Line projects often trend toward the higher, premium-material end. Composite and PVC decking (Trex, TimberTech, AZEK) cost more upfront than pressure-treated wood but need far less maintenance over their lifespan.

Are deck builders in the Main Line required to be licensed?

Yes. Pennsylvania requires home-improvement contractors doing more than $5,000 of work per year to register with the PA Attorney General (a "PA HIC" number), and most townships require a building permit and footing inspection for a new deck. Always confirm a builder’s PA HIC registration and that they pull permits — JHL Deck Builders, for example, is PA HIC #PA035784 and files permits with your township.

Composite or wood decking — which is better in Pennsylvania?

Composite and PVC decking (Trex, TimberTech, AZEK) resist Pennsylvania’s freeze-thaw cycles, rot and fading and need no staining, but cost more upfront. Pressure-treated and cedar wood cost less initially but require regular sealing. For most homeowners staying long-term, composite’s lower lifetime maintenance wins out.
