New Construction Services

Over the years, Griffith Exteriors has earned the reputation as the premier new construction company in the area and we have had the privilege of servicing both large national builders as well as local and regional builders.  Our primary focus is larger scale subdivisions, utilizing fiber cement siding by James Hardie as well as Allura. Our track record of excellence has enabled our services to be spread throughout Southeastern PA and the NJ markets.


GAF Timberline HD is our preferred shingle and we have Master Elite status with GAF. We have received numerous awards from this manufacturer including the Triple Excellence and Presidents Club award.  We endeavor to train our teams for the specific details and challenges presented by the builders we work with.  This is accomplished through training as well as incentive based programs that have proven to be successful.  We also work with builders to determine appropriate real-world details to ensure smoother production and minimize call backs.


Although vinyl siding is part of our catalogue the majority of our work is done with fiber cement siding by Allura or James Hardie.  Fiber cement siding presents unique installation challenges and we have worked over the years to train our installation teams in the best practices of installation and time reducing techniques that speed up our installation process.  We have done in-shop and onsite training with our manufacturer partners and are James Hardie and Allura credentialed installers.  Our commitment to quality in a production environment has been a key ingredient to our success and has helped our market grow significantly.

PVC Trim

Although some builders have the PVC trim work installed by the framing contractor several have opted to have our team handle those details (in conjunction with siding work) and the results speak for themselves.  We manufacture shop made PVC window surrounds including thermo-formed arch top units.  Our exterior trims are all fastened using stainless steel fasteners or screws.

Metal Roofing

We have a full service sheet metal shop featuring two CNC sheet metal folding machines, an extended length shear table and a roof panel machine by Newtech.  Our 24ga standard material is Kynar finished for extra durability and UV resistance so that your roof looks good year after year.  The paint has a 35 year warranty!


Our company endeavors to promote safety on our job sites.  This is accomplished through tool-box talks, onsite inspections and safety meetings.  Our company was an industry first to offer a safety compliance program and a safety equipment trade up program.


We have a fleet of equipment including telehandlers and articulating lifts.  This equipment is invaluable when installing fiber cement siding as it allows us to maneuver materials around buildings which dramatically reduces our install times.
