Serving Newtown Square & Surrounding Areas
Our Newtown Square studio is home base — 12 Smedley Ln, serving the Main Line and Delaware County. We design and build custom composite, Trex, and wood decks, porches, and railings for homeowners across Edgmont, Newtown Township, and the surrounding communities, fully permitted and backed by our workmanship warranty.
We build in Trex, TimberTech, and AZEK composite and PVC decking as well as traditional pressure-treated and cedar wood, and finish every deck with composite, cable, and aluminum railing systems from Keylink and RDI. Every JHL build is permitted with your township, set on code-depth concrete footings with properly flashed ledgers and framing, and signed off at final inspection — the structural details that decide whether a deck lasts 10 years or 30.

JHL Deck Builders did an amazing job on our new composite deck. The craftsmanship is outstanding, and the entire team was professional from start to finish. They kept us informed throughout the project and delivered exactly what they promised. We couldn't be happier with the final result.
After getting several estimates, we chose JHL for our wood deck construction project. Their pricing was fair, and the quality exceeded our expectations. The deck is sturdy, attractive, and built to last. Highly recommended.
The custom deck with stairs that JHL built for us looks incredible. Everything was completed with precision and care. The stairs are sturdy, comfortable to use, and blend perfectly with the overall design.
Great company to work with. They listened to our ideas and turned them into a stunning outdoor space.
JHL Deck Builders designed a deck and patio combination that completely changed the look of our backyard. The team offered great suggestions and created a functional outdoor living space that our family uses every day.
Deck Building FAQs — Newtown Square, PA
How much does a deck cost in Newtown Square, PA?
A professionally permitted custom deck in Newtown Square typically runs $25,000–$55,000 — composite (TimberTech, Trex, AZEK) at the higher end, pressure-treated wood at the lower. Size, elevation, railing type, and features drive the number. We give you a detailed written quote after a free on-site visit.
Do I need a permit to build a deck in Newtown Square?
Almost always. Any deck attached to the house or more than 30 inches above grade requires a building permit in Delaware County townships. We handle submission, plan review, and inspections as part of every project.
Composite or wood — which should I choose?
Composite (TimberTech, Trex, AZEK) costs more upfront but needs no staining or sealing and lasts 25–40+ years; pressure-treated wood is cheaper but needs ongoing maintenance. We price both on your estimate so you can compare real numbers.
How long does a deck build take?
Most projects schedule 3–6 weeks after you accept the quote (permit-dependent) and take roughly 1–3 weeks on site, depending on size and elevation. We give you an honest timeline on the estimate visit.
Are you licensed and insured?
Yes — JHL Deck Builders is a registered Pennsylvania Home Improvement Contractor (PA HIC #PA035784), fully insured, OSHA compliant, and BBB rated.
