From new construction cladding to emergency storm repairs, Forge Siding delivers field-tested Siding across Duncannon and the surrounding PA service area. Call today for a free on-site estimate.

What separates our Duncannon operation from the competition isn't a slogan — it's the fact that every estimate we write is signed by a licensed contractor, every project has a named lead installer accountable for the outcome, and every job site is cleaned before we leave at night.
Our Duncannon, PA teams operate on a tight scheduling protocol: we don't book jobs we can't start within a reasonable window, we communicate proactively if anything in the timeline shifts, and we don't consider a project closed until the customer signs off on the walkthrough.
Licensed, bonded, and carrying full general liability plus workers' compensation in PA — not because it's optional, but because those protections matter for homeowners who invite a crew onto their property. Ask for our certificate of insurance before signing anything; we provide it without hesitation.

Most siding problems start small and quiet — a missed fastener, a failed caulk joint, a crack that looks cosmetic. By the time interior moisture damage appears, the repair scope has usually doubled. Watch for these early signals.
Hairline fractures in vinyl or fiber cement are entry points for water. Even a small crack at a window corner can let moisture work into sheathing within a few rain cycles.
Musty smell in exterior-adjacent rooms, soft drywall near windows, or paint bubbling on interior walls all point to moisture infiltration from outside. Don't wait.
Warped vinyl often means panels were installed too tight — no expansion room for thermal movement. Over time, buckling creates gap points where panels separate at the lock, letting wind and water in.
Exterior paint peeling within two to three years of a repaint is almost always a substrate or back-priming issue. We diagnose the cause before recommending a fix.
Fastener issues are quiet until they're catastrophic. A section that blows off in a windstorm — and the water damage that follows — costs far more to fix than a fastener re-drive.
Failing siding, missing housewrap, or compromised flashing at penetrations significantly reduces wall R-value and allows air infiltration. If your heating and cooling costs have climbed without a clear explanation, the building envelope is a legitimate suspect.
Our Duncannon, PA team handles the full range of residential and commercial cladding work, from single-panel repairs to complete building envelope re-siding.
New siding installation covers everything from the housewrap to the trim: starter strip, flashing at all penetrations, panel installation per manufacturer spec, and finishing trim at corners, windows, and the roofline. We work on new construction alongside GCs and handle full tear-off replacements on existing homes. Our Duncannon, PA crews are certified on vinyl, fiber cement, engineered wood, and steel panel systems — and we carry each product's installation manual on every job.

For insurance-related repairs, we produce a detailed damage documentation package — panel-level photos, square footage by elevation, material specifications — formatted for adjuster review. We've worked with every major carrier operating in PA and understand what documentation a claim requires.

Each cladding material has its own installation requirements, failure modes, and maintenance profile — and a crew that treats them all identically is a crew that will make material-specific mistakes. Our Duncannon, PA specialists understand fiber cement's silica cutting protocols and back-priming requirements, vinyl's thermal expansion characteristics and lock-engagement tolerances, and wood's moisture content sensitivity and end-grain sealing needs. We don't sell you a product and then install it generically.

Commercial cladding projects in Duncannon, PA operate on different constraints than residential work: higher fastener schedules for wind-load compliance, special inspection requirements in some jurisdictions, tighter sequencing requirements with other trades, and often a need for resident or business-continuity scheduling coordination on occupied buildings. Our commercial Siding crews are familiar with the permitting landscape in PA and have completed projects ranging from 10-unit townhome communities to larger multi-family re-siding contracts.

On replacement projects, we replace trim components that are damaged or compromised regardless of the primary panel material — because leaving old, failing trim behind a new siding installation creates the exact problem the new siding was supposed to solve.

Post-storm inspections document hail and wind damage at panel face level — the kind of close-range documentation that insurance adjusters need for a full-scope claim approval. We've helped Duncannon, PA homeowners recover adjuster-approved claim settlements that significantly exceeded initial offers, simply by providing specific panel-level evidence instead of general descriptions.

There are plenty of siding contractors in PA. Here's what separates the ones worth hiring from the ones who cost you twice — once for the job and once for fixing what they did wrong.
Every estimate we write lists materials, labor, and any permit fees as separate line items. You know what you're paying for before signing anything — no lump-sum guesses that hide markup.
Our PA dispatch operates from locally based crews — not a regional office routing jobs to whoever's available statewide. That means faster arrival windows, familiarity with local permit offices, and crews who understand Duncannon, PA building code requirements.
Our PA contractor license number is provided at first contact. Look it up in the state database before signing anything — we encourage it. We carry current general liability and workers' compensation; certificates are available on request.
A warranty that isn't in writing isn't a warranty. Ours is a document you can file, reference, and enforce.
A crew that leaves a clean site every evening is a crew that respects the property they're working on. Our standard includes daily cleanup as a non-negotiable part of the project schedule.
Every Forge Siding project in Duncannon, PA closes with a documentation package: permit records, manufacturer warranty registrations, post-project photos by elevation, and our workmanship warranty. That file is useful for insurance claims, home sales, and HOA records long after the project ends.
A predictable process reduces stress and produces better results. Here's exactly what happens when you contact our Duncannon, PA team.
Your first call goes to a real dispatcher who asks the right questions. We arrive at the site assessment with the tools to measure, probe for moisture, and give you an accurate picture of what the project actually involves.
You receive a line-item estimate within 24 hours of the site visit. We bring material samples to the estimate meeting and walk through product trade-offs relevant to your Duncannon, PA property — climate exposure, HOA requirements, budget, and maintenance preference all factor into the recommendation.
Material is ordered against the confirmed schedule. We don't start jobs with missing material. Your crew arrives on day one with everything staged and a clear sequence plan for the project.
Surprises are handled on your schedule, not ours. We document unexpected findings with photos, give you the repair cost in writing, and proceed only with your explicit sign-off.
The walkthrough isn't a formality. If anything isn't right, we note it and fix it before considering the project closed. Our reputation runs on completed projects, not signed contracts.
We back every Siding project in PA with a written workmanship warranty. The warranty period, covered defects, and resolution process are all spelled out before we start. No fine print that swallows the coverage.
📞 +1-844-782-0929 — Free Estimate TodayThree bids, three different approaches. Forge Siding was the only contractor who showed up with a moisture meter at the estimate visit and flagged elevated readings behind our north-facing panels before we even discussed product. That kind of diagnostic thoroughness sold us immediately.
Emergency call on a Saturday night after wind blew off eight panels on the back wall. Someone actually answered. Crew was on site Sunday morning, boarded up the exposed section, and had permanent panels installed by Tuesday. I'd been skeptical of "24/7" claims from other contractors — this is what it actually looks like.
Pre-purchase inspection on a property we were considering saved us from a significant surprise. Forge Siding found sheathing moisture on two wall sections that the general home inspector had noted as "siding in acceptable condition." The seller ended up crediting the repair cost. That inspection paid for itself many times over.
Fiber cement installation — the back-priming, the fastener schedule documentation, the warranty registration process — was handled exactly as the manufacturer requires. Our close-out package has the Preferred Contractor registration and the complete fastener log. The 30-year warranty is in force.
The crew found rotted sheathing on the west wall during tear-off. Called me immediately, showed me exactly what they found with photos, and gave me the change order before touching anything. The whole process was transparent from start to finish — that's exactly how contractors should handle unexpected conditions.
I verified their license number in the state database before signing. Current, no disciplinary history. That two-minute check told me this was a contractor operating transparently. Everything about the project execution matched that first impression.
Our Duncannon-based team handles every project in the service area — meaning the same crew that handles a large commercial contract is available for residential repairs in surrounding communities. Proximity matters for response time, familiarity with local inspectors, and the practical ability to return quickly if any post-project follow-up is needed.
