When your siding fails, it doesn't fail quietly. Moisture gets into sheathing, energy costs climb, and the interior damage that follows is always more expensive than the exterior repair that would have stopped it. Forge Siding puts licensed, manufacturer-certified crews on your Dunellen property — crews who diagnose the actual problem, price it in writing, and fix it once.

Forge Siding has been delivering Siding across Dunellen, NJ for over fifteen years. Our lead installers hold manufacturer certifications on every cladding system we install — fiber cement, vinyl, engineered wood, steel — and the same crew that estimates your project executes it. We don't sub out the technical work.
Our NJ operation is licensed, bonded, and insured — GL and workers' comp both current, certificates available before any project starts. Not because it's optional, but because a property owner deserves protection when they invite a crew onto their building.
We've completed projects in every climate zone Dunellen, NJ presents — high-humidity coastal exposures, high-altitude freeze-thaw cycling, urban heat island conditions. That geographic breadth translates to practical knowledge about product selection and installation specification that out-of-market contractors working from a generic spec sheet simply don't have.

These are the signals that experienced crews look for on every Dunellen, NJ property inspection. Missing them is how a $400 repair becomes a $4,000 wall reconstruction.
Any crack through the panel face is an active moisture entry point. Window corners and butt joints are the highest-risk locations — and the easiest to overlook until they've allowed a full season of water infiltration.
Interior moisture near windows is frequently misdiagnosed as a window problem. Failed flashing or caulk at the rough opening — a siding-system issue — is the actual source in the majority of cases we diagnose in NJ.
Buckled vinyl means panels were installed too tight for the thermal range — no expansion room for seasonal movement. The deformation grows with each heat cycle and eventually opens the panel lock, creating wind and water entry points.
On fiber cement specifically, field cuts that weren't back-primed at installation are the entry point. The paint fails at cut edges first and the pattern makes the cause obvious to anyone who's diagnosed it before.
Fastener specification is the most commonly skipped installation requirement. We've documented hundreds of Dunellen, NJ properties where the original installer used bright nails on fiber cement, voiding the material warranty before the first winter.
Wall air leakage through siding failures can account for 10–20% of annual HVAC energy consumption. Addressing the envelope often produces measurable utility savings alongside the repair value.
Every service below is performed by our own licensed crew — not passed to a subcontractor network we don't control. We carry the manufacturer certifications, the diagnostic tools, and the installation experience for every scope we quote.
New siding installation covers the complete scope: housewrap, flashing at all penetrations, panel installation per manufacturer specification, and finishing trim at corners, windows, doors, and the roofline. We work on new construction alongside general contractors and handle full tear-off replacements on existing Dunellen, NJ homes and commercial properties. Our crews are certified on vinyl, fiber cement, engineered wood, and steel panel systems — with the documentation to keep every material warranty in force.
We also handle the complete trim system: corner posts, J-channel, soffit panels, fascia wrap, and all penetration accessories. Not as an optional add-on — as part of every installation scope, because a new siding system that terminates into failing trim defeats the purpose of the project.

Root cause diagnosis before any repair work is our standing process. A cracked panel that gets swapped without investigating the housewrap beneath, a caulk joint that gets re-sealed without checking sheathing moisture — these are surface patches over active problems. We find the cause first, quote the actual fix in writing, and then execute.
Emergency dispatch for genuine siding emergencies — missing panels with rain incoming, active moisture entry into a wall cavity, structural damage — is available around the clock. A live dispatcher answers, not an answering queue. We triage by exposure severity and send a crew based on actual risk.

Manufacturer certification matters for one concrete reason: it's the difference between a material warranty that's in force and one that's already voided before the project is complete. Our James Hardie Preferred Contractor status, for example, means the 30-year material warranty on every fiber cement project we complete is fully registered in the client's name at project close.
Beyond installation, we perform professional siding inspections — pre-purchase assessments for buyers, post-storm condition reports for insurance claims, and annual maintenance inspections for property owners who want to catch caulk failures and minor fastener movement before they become moisture damage. These inspections use calibrated pin-type and non-invasive capacitance meters for moisture assessment — tools a general home inspector doesn't carry. The written report you receive ranks deficiencies by priority and includes rough cost ranges for every item.

Vinyl soffit and fascia wrap, HardieTrim boards, aluminum-capped fascia, and fiber cement trim boards are all within our scope. On replacement projects, we replace trim components that are damaged or compromised regardless of the primary panel material — because leaving failing trim behind a new siding installation creates the exact moisture entry point the new siding was supposed to eliminate.

Post-storm inspections document hail and wind damage at panel face level — the close-range evidence that insurance adjusters need for full-scope claim approvals. We've helped Dunellen, NJ property owners recover claim settlements that significantly exceeded initial adjuster estimates by providing specific, photo-verifiable panel-count documentation rather than general damage descriptions.

Property managers and HOA boards working with us get a dedicated project point of contact, building-by-building scheduling documentation, and a close-out package — permit records, warranty registrations, per-building photos — formatted for board records and institutional property management systems.

These aren't aspirational claims. They're the operational standards our Dunellen, NJ clients reference when they send us referrals. Each one is documented and verifiable.
Lump-sum estimates are the contractor's tool. Line-item estimates are the client's. We provide the latter on every project, from a single-panel repair to a full commercial re-siding contract.
Our NJ crews operate from locally based dispatch — not a regional hub routing jobs to whoever's available statewide. That means faster arrival windows, familiarity with local building departments, and crews who know Dunellen's specific code requirements.
Our NJ contractor license number is provided at first contact. Two minutes in the state database tells you our status, our classification, and our disciplinary history. GL and workers' comp certificates are available before work starts — not expired documents or certificates for a different company name.
We also deliver a complete close-out package: permit records, manufacturer warranty registrations, and post-project photos organized by elevation. That file is useful for insurance renewals, property sales, and HOA records long after the project ends.
Staging tarps protect landscaping and driveways before demo starts. We sweep for fasteners every afternoon before the crew leaves. Debris is hauled off-site rather than sitting in a roll-off on your driveway for three weeks after the project ends.
The lead installer contacts you each morning to confirm the day's scope and each afternoon to report what was completed. If the project uncovers unexpected conditions — the sheathing damage that shows up during tear-off — you hear about it same-day with photos and a written change order, before we touch anything additional.
A predictable process consistently produces better results than a flexible one. Here's exactly what to expect.
Our Dunellen, NJ dispatch team takes your call and books a free on-site assessment within 24–48 hours. We arrive with measuring tools and a moisture meter, document all wall planes and existing substrate conditions, and identify any issues before quoting.
The estimate is a document, not a handshake. It becomes the contract, and every line item is visible before you sign. No lump-sum number to parse after the fact.
Where permits are required in NJ, we handle the application, filing fee, and inspection scheduling as part of standard scope. Your confirmed start date is in writing and the crew assignment is confirmed before materials are ordered.
Morning update from the lead installer confirming the day's scope. Afternoon update reporting what was completed. Unexpected substrate conditions documented same-day with photos and a written change order — never added to the invoice without prior approval.
Close-out package delivered: permit records, manufacturer warranty registrations in your name, post-project photos by elevation, and our signed workmanship warranty document. Everything in one organized file.
The moisture meter reading at the estimate visit — before we'd agreed to anything — flagged elevated sheathing moisture behind our north wall. That diagnostic step upfront told me immediately what kind of contractor I was dealing with. The rest of the project matched that first impression exactly.
The insurance documentation package they produced — panel-by-panel photos, written damage scope by elevation — got our claim approved at full replacement on first review. The adjuster told us it was the most detailed storm documentation he'd seen that year.
Pre-purchase inspection on a property we were evaluating found sheathing moisture on two elevations the general home inspector had completely missed. Used the written report to negotiate a $12,000 seller credit. The inspection paid for itself about 40 times over.
They found rotted sheathing on the west wall during tear-off. Called me within the hour, showed me the photos, issued a change order before doing anything. That's the process working exactly as it should — and it's shockingly rare in my experience with contractors.
Fiber cement installation — the back-priming at every field cut, the fastener schedule documentation, the manufacturer warranty registration. I've seen fiber cement installed by other contractors. I know what the correct process looks like. Forge Siding followed every step of it.
Three bids — two lump sums and one line-item breakdown from Forge Siding. The line-item document made comparison possible in a way the other two bids didn't. When the choice becomes that clear, the decision is easy.
Forge Siding provides residential and commercial Siding across the full Dunellen, NJ service area from our locally based Dunellen dispatch team. We're familiar with local building codes, permit requirements, and contractor licensing standards throughout NJ — no learning curve on your project, no out-of-area crew navigating unfamiliar inspectors and building departments for the first time.
