Trusted Siding Contractor Main Line PA
Your home’s siding is the first line of defense against Pennsylvania’s climate and the first thing every visitor, every neighbor, and every potential buyer sees. When it is failing, cracking, fading, or trapping moisture behind the surface, the consequences compound quickly. When it is performing correctly, it protects your home’s structure, reduces energy costs, and maintains the curb appeal that drives Main Line property values. Hynes Construction has been serving homeowners across Main Line PA as a trusted siding contractor from our office at 119 Sibley Avenue, Ardmore PA 19003 for over 50 years. We offer three primary siding services like James Hardie fiber cement siding installation, vinyl siding installation and replacement, and stucco remediation and re-cladding. All of these are performed by our own experienced crews, not subcontractors, and all are covered by written warranties. Request your free estimate today or call 610-880-3890.
Siding Services We Offer Across Main Line PA
Every siding service below is available across all 30+ communities in our Main Line service area. Click through to the dedicated page for each service for full detail, product specifications, installation process, and current pricing guidance.James Hardie Fiber Cement Siding
James Hardie fiber cement siding is the most installed premium siding on the Main Line and the option we recommend for the region’s Colonial, Victorian, Craftsman, and Tudor architectural styles. Fiber cement does not absorb moisture, does not crack under Pennsylvania freeze-thaw cycling, does not support mold growth, and is noncombustible. It carries a 30-year non-prorated transferable product warranty and a 15-year ColorPlus factory finish warranty against peeling, cracking, and chipping. Manufactured to HardieZone 5 specifications, engineered specifically for the northern climate zone that covers all of southeastern Pennsylvania. As a James Hardie certified installer, Hynes Construction provides access to the full Hardie product line, including HardiePlank lap siding, HardieShingle, HardiePanel vertical siding, and HardieTrim.Vinyl Siding Installation and Replacement
Vinyl siding is a durable, low-maintenance option for Main Line homeowners where cost per square foot is the primary driver and premium material specifications are not required. Modern insulated vinyl siding delivers 20 to 30 years of reliable performance with no painting, no staining, and no annual maintenance requirement. We install multiple profiles, including traditional lap, Dutch lap, beaded lap, board-and-batten, and shake-profile panels. Correct installation, meaning a proper moisture barrier, correct flashing at every window, door, and penetration, and adequate expansion gap management are what determine whether vinyl siding performs for 25 years or fails in 10. Our installation follows manufacturer specifications on every project.Stucco Remediation
Stucco remediation is one of the most urgent and most frequently underdiagnosed home maintenance needs on the Main Line. Tens of thousands of homes built between 1985 and 2005 across Chester, Delaware, and Montgomery Counties were clad in stucco or EIFS systems that are now trapping moisture inside wall cavities and silently deteriorating structural sheathing and framing from the inside. By the time visible symptoms appear, the structural damage is already significant. Our remediation process begins with a professional moisture inspection using deep probe testing and infrared thermal imaging before any scope is written. Full removal, structural repair, window re-flashing, water-resistive barrier installation, and new cladding over the corrected system follow. Most Main Line homeowners replace stucco with James Hardie fiber cement siding.Why Main Line Homeowners Choose Hynes Construction for Siding

Signs Your Main Line Home Needs New Siding
Fading or Discoloration
Siding that has faded significantly, developed permanent staining, or changed color unevenly is past its color warranty period. On vinyl siding, UV degradation after 20 to 25 years causes irreversible color change and surface chalking. On painted fiber cement, fading indicates the paint film has broken down and the substrate is now exposed. On stucco, widespread discoloration often signals moisture accumulation behind the surface rather than cosmetic aging. A professional assessment determines whether the issue is cosmetic or structural.Warping, Buckling, or Cracks
Warped or buckled vinyl panels indicate either improper installation (insufficient expansion gaps) or UV degradation of the PVC compound after years of exposure. Cracked or spalled fiber cement indicates impact damage or, in improperly installed systems, freeze-thaw damage from moisture that entered through failed caulking. Cracked stucco at window corners or along material interfaces is a high-priority finding; these are active water entry points, not cosmetic damage.Moisture Damage or Mold
Visible mold or mildew on exterior siding surfaces indicates a moisture management failure either in the siding material itself or in the underlying wall assembly. Mold on the interior side of exterior walls, visible when walls are opened during renovation, indicates that the siding system has been failing to manage moisture for a sustained period. This is the condition that defines the stucco crisis on the Main Line. Our stucco remediation service addresses this systematically, beginning with a professional moisture inspection before any scope is committed.Rising Energy Bills
Siding that has lost its thermal integrity through gaps, failed caulking, or compressed or absent wall insulation behind an aging exterior allows heat transfer that shows up as higher heating and cooling costs. Insulated vinyl siding, with its foam-backed core, or James Hardie fiber cement with continuous exterior insulation under the cladding, can deliver meaningful reductions in energy transfer compared to aged single-layer vinyl or deteriorating stucco systems.Storm Damage
High-wind events above 60 mph are common in Main Line Nor’easters and summer convective storms can crack vinyl panels, dent and fracture fiber cement, and open gaps at siding joints and trim connections. Hail impacts leave visible bruising on vinyl and surface cracking on stucco. Any storm damage that opens the wall assembly to water infiltration requires prompt assessment. Our insurance claims assistance program handles damage documentation and adjuster coordination for storm-related siding claims.Our Siding Installation Process
01 Free On-Site Assessment: We visit your property and assess the full exterior – existing siding condition, substrate condition, window and door flashing status, penetration seals, and any signs of moisture infiltration. For homes with stucco or EIFS, this includes prober moisture testing. A written assessment with photographs is provided at no charge. 02 Written Estimate and Scope: You receive a written, itemized estimate specifying the exact product by name and grade; installation standard; what is and is not included; permit handling; timeline; and price. No verbal quotes. 03 Material Selection and Scheduling: For James Hardie installations, we guide you through profile and color selection across the full Hardie line. For vinyl, we provide product samples from our installed product range. Materials are ordered and scheduled for delivery before the project start date is confirmed. 04 Installation, Final Inspection, and Cleanup: All existing siding is removed, substrate is inspected, any damaged material is replaced, moisture barrier is installed, and new siding is applied to manufacturer specifications. Every window, door, and penetration is correctly flashed before the siding goes on. The site is cleaned completely at project close. Written warranty documentation is provided on the final day.Siding Services for Commercial Properties on the Main Line
Hynes Construction installs commercial exterior siding for retail, office, mixed-use, and light industrial properties throughout the Main Line. Commercial siding projects require coordination with commercial permits from Lower Merion Township, Haverford Township, or the relevant municipal authority, and scheduling that minimizes disruption to active business operations. We install James Hardie fiber cement panel systems, vinyl commercial siding, and fiber cement board-and-batten profiles appropriate for commercial exteriors. We carry commercial general liability coverage in the amounts that commercial property owners and property managers require. Contact us to discuss your commercial siding project.Serving Main Line PA and Greater Philadelphia

Frequently Asked Questions: Siding Contractor Main Line PA
James Hardie fiber cement siding is the most appropriate choice for Main Line PA homes from a performance, durability, and architectural compatibility standpoint. It is engineered for Pennsylvania’s freeze-thaw climate (HardieZone 5), carries a 30-year non-prorated transferable warranty, and offers profiles appropriate for the Colonial, Victorian, Craftsman, and Tudor homes that define the region. Vinyl siding is a reliable and cost-effective alternative where budget is the primary driver. See our full siding materials comparison for a side-by-side breakdown.
Siding installation costs in Main Line PA vary by material, scope, and whether structural repairs are needed. As general guidance: vinyl siding installation runs $6 to $12 per square foot installed. James Hardie fiber cement runs $10 to $20+ per square foot installed depending on product line and profile. Stucco remediation (removal plus replacement) runs $15,000 to over $100,000 total for a Main Line home, depending on the extent of moisture damage discovered. All estimates are free and written. Call (610) 983-8644 or request online.
A full siding re-installation on a typical Main Line single-family home takes 3 to 7 days depending on the size of the home, the profile and complexity of the exterior, and whether substrate repairs are needed. Stucco remediation projects take longer – typically 1 to 3 weeks for a standard project, with additional time if significant structural repair is discovered during stucco removal. Permit processing is factored into the schedule before work begins.
Yes, consistently. Siding replacement is one of the exterior projects with the strongest return on investment in the Main Line real estate market, particularly for James Hardie fiber cement, which signals premium quality to buyers and appraisers in Chester and Delaware Counties. A new siding installation also removes one of the most common buyer contingency triggers in this market: failed stucco or aging vinyl that a buyer’s inspector flags as a deferred maintenance item. Projects completed before listing typically return more than their cost through cleaner transactions and stronger buyer confidence.
Yes. We handle HOA architectural review submissions and municipal permit applications for all siding projects that require them. Properties within Lower Merion Township’s historic district may require a Certificate of Appropriateness from the borough before exterior cladding changes. We are familiar with both processes and manage all submissions as part of the standard project scope.
Matching existing siding is possible for current-production products. For James Hardie fiber cement in production profiles and standard colors, matching is straightforward. For vinyl siding, matching is possible for products still in production but becomes more difficult for older profiles that have been discontinued. For stucco partial repair (as opposed to full remediation), color and texture matching is possible but not always perfect, particularly on aged and weathered surfaces. We assess matchability during the free estimate visit
Yes. We offer financing options including 0% interest plans for qualified homeowners. Siding installation, stucco remediation, and multi-trade exterior projects all qualify. Ask your estimator about current terms and repayment periods during your free assessment appointment.
Warranty coverage depends on the material selected. James Hardie fiber cement carries a 30-year non-prorated transferable product warranty and a 15-year ColorPlus finish warranty against peeling, cracking, and chipping. Vinyl siding carries the manufacturer’s warranty for the specific product line selected, typically 20 to 30 years. We provide a separate written workmanship warranty from Hynes Construction on all installations. Full details on our warranties page.
