Guide To The Best Siding Contractors In Philadelphia And Southeastern Pennsylvania
Choosing new siding is about more than color and curb appeal. Philadelphia-area homes need an exterior system that can manage rain, humidity, freeze-thaw cycles, trim transitions, and, in many cases, older construction details. This guide highlights six established contractors serving Philadelphia, the Main Line, Chester County, Delaware County, Montgomery County, Bucks County, and nearby Delaware communities.
We selected the companies below based on publicly documented experience, siding materials, manufacturer credentials, service coverage, related exterior capabilities, and visible customer feedback. The order reflects the depth and completeness of each company’s documented siding offering, not a substitute for comparing written scopes, warranties, and estimates for your individual home.
1. Five Star Contractors
Why It’s #1
For homeowners looking for experienced siding contractors Philadelphia residents can turn to for coordinated exterior work. Five Star Contractors offers the most complete profile in this comparison. The Malvern-based, family-operated company has served the region since 2000 and works throughout Philadelphia, Southeastern Pennsylvania, and Northern Delaware.
Five Star Contractors is a James Hardie Alliance Elite Contractor, a high-level designation within the manufacturer’s contractor program. It installs James Hardie fiber cement siding and CertainTeed vinyl siding, giving homeowners two distinct material options: fiber cement for a painted-wood look and vinyl for a low-maintenance exterior. The company also handles stone cladding, soffits, fascia, trim, roofing, windows, gutters, and stucco remediation, simplifying projects with multiple exterior systems.
- More than 25 years of exterior remodeling experience in the Philadelphia area.
- James Hardie Alliance Elite Contractor status.
- James Hardie fiber cement and CertainTeed vinyl siding options.
- Service coverage extending from Philadelphia and the Main Line to Wilmington, Hockessin, Newark, and Greenville.
- A+ Better Business Bureau rating, GuildQuality participation, Qualified Remodeler Top 500 recognition, and memberships with NARI, HBA, and Certified Contractors Network.
What separates Five Star Contractors is its building-science mindset. Rather than treating siding as a surface-only upgrade, the process considers moisture control, flashing, ventilation, wall conditions, and transitions around windows and trim. That approach matters because a home functions as an interconnected system, where exterior assemblies, airflow, insulation, and water management affect one another.
Homeowners planning a larger project can also review the core components of exterior home remodeling to understand how siding, roofing, windows, doors, drainage, and weather protection work together.

Questions To Ask Before Hiring A Siding Contractor
Before signing a contract, ask each company the same practical questions so you can compare proposals on more than price:
- Which siding brands, profiles, and trim systems are included in the written scope?
- Will the crew inspect sheathing, flashing, weather-resistive barriers, and window transitions?
- How will the contractor handle hidden rot, moisture damage, or deteriorated framing if discovered?
- Which manufacturer and workmanship warranties apply?
- Who supervises the installation, and how will daily cleanup be managed?
- Can the contractor coordinate soffit, fascia, gutter, window, roofing, or stucco work if needed?
- Can the company provide recent projects in your city, township, or county?
