Cracked panels, warped boards, peeling paint — these are signs your siding is failing before your eyes. Forge Siding delivers professional Siding across Allentown, NJ with upfront pricing and crews who show up on schedule.

We didn't start Forge Siding to push volume — we built it because homeowners in Allentown kept getting burned by crews who cut corners on material selection, skipped moisture barriers, and left job sites messy. That's not how we work. Every Siding project starts with an honest assessment: we look at your substrate condition, check for existing rot or moisture intrusion, and talk through your options before a single nail goes in.
Every estimate is itemized and written down before we ever ask for a signature. You'll see material costs, labor, disposal, and any underlying repair work broken out separately — so you know exactly what you're paying for and why. We've completed thousands of Siding projects across Allentown, NJ and our callback rate is under two percent. That number matters to us.

Most homeowners don't notice siding problems until water damage has already reached the sheathing. These are the signals worth acting on before the repair scope doubles.
Even a small gap at a butt joint or around a window trim is an entry point. Water wicks in, freeze-thaw cycles widen the gap, and the damage compounds every winter.
Buckling almost always means the substrate underneath has moved — often because moisture got behind the panel weeks or months ago. The panel is showing you the symptom, not the cause.
Interior peeling close to an outside wall isn't a paint problem — it's a moisture infiltration problem. Your siding is the likely culprit and ignoring it turns a siding job into a drywall and mold job.
A missing panel after a wind event or impact isn't just cosmetic damage. That exposed sheathing is collecting rain until you replace it. This is one repair that can't wait for a convenient schedule.
Old or failing siding, particularly if the housewrap underneath has deteriorated, acts like a thermal short-circuit. Your HVAC runs harder to compensate, and the bills reflect it before the siding looks obviously bad.
Heavy algae or mold staining on the exterior surface isn't just cosmetic — it means the surface is retaining moisture long enough for organic growth. That moisture is also working its way into the wall system.
Every job below starts with a free written estimate. We specify the product, the profile, the color, and the installation method upfront — so there's no ambiguity when work begins.

Fiber cement is the workhorse material we recommend most in NJ's climate — it handles humidity, impact, and UV better than most alternatives and carries manufacturer warranties that actually hold up. We're certified installers for HardiePlank, HardieShingle, and competing fiber cement systems. Installation follows manufacturer specs to the millimeter: correct lap, correct fastener type and spacing, correct clearance from grade and roof surface, and full housewrap integration on every project.

Done right, vinyl siding is durable, low-maintenance, and cost-effective. Done wrong — wrong gauge, wrong fastener pattern, no expansion clearance — it warps in the heat and pulls loose in wind. We use .044" and .046" gauge panels minimum and follow thermal expansion specs precisely for NJ's temperature range. Nail hem fastening at 16" centers, 1/32" expansion gap at all trim terminations, and a fully integrated vinyl accessory system so the corners, J-channel, and window trim all work together.

Engineered wood is popular in Allentown neighborhoods where the traditional wood look matters architecturally but the maintenance demands of real cedar or pine aren't practical. We install with stainless or hot-dipped galvanized fasteners to prevent iron staining at the nail head — a detail that separates a professional installation from a quick flip job.

Not every siding problem needs a full re-side. Storm impact, vandalism, or isolated rot can often be addressed with a targeted repair that blends into the existing field. We stock common profiles and can often source discontinued patterns through our supplier network for historic or older homes where matching matters. Partial replacement work is priced honestly — if we see a repair scope that's going to creep, we say so before we start, not after.
We work with metal panel systems, large-format fiber cement, and commercial-grade vinyl for multi-family and light commercial applications. EIFS compatibility work, expansion joint detailing, and coordination with waterproofing and window subcontractors are all in scope. We carry the insurance requirements for commercial GC work and can provide certified payroll documentation for public projects.
Siding that terminates at rotted or missing fascia boards isn't protected — it's channeling water straight into the rafter tails. We routinely pair siding replacement with trim, soffit, and fascia work so the entire exterior envelope is addressed in one mobilization rather than two. PVC trim board, prefinished aluminum coil, and fiber cement fascia are all in our wheelhouse.
Four steps. Each one documented. No surprises at the invoice.
We come out, examine your existing cladding, probe for soft substrate, check flashing and housewrap condition at visible penetrations, and give you an honest assessment of what we're working with. No high-pressure sales — just a clear picture of the project scope before we talk numbers.
You receive a line-by-line written estimate: material cost by product and quantity, labor, removal and disposal of existing siding, and any sheathing repair identified in the assessment. We walk through material options with physical samples, not just catalog photos. You sign off on the spec before we order anything.
Your start date is locked at signing. Crew arrives on time, materials are staged and ready, and the site is protected before demo begins. We run a tight job — no leaving panels exposed overnight when rain is in the forecast.
At project completion, we walk the entire exterior with you. Every run of siding, every corner, every trim termination — you look at it before we close out. If anything isn't right, it gets fixed on the spot. Our goal is that you refer us to your neighbor the week after the project wraps.

Every crew that works on your home carries a current contractor's license for NJ, full general liability, and workers' compensation. We'll email you the certificates before we arrive — not after you ask three times.
Upfront pricing means you know what you're paying before a single panel comes off the wall. Change orders require your written approval. We've built our reputation in Allentown, NJ on the fact that our estimates are reliable.
We run our calendar tightly so the start date we give you is the date we're there. If a legitimate delay comes up — major weather, material shortage — we call you the day before and reschedule immediately, not a week later.
We've seen what happens when crews leave siding debris sitting for a week. Nails in the lawn, panels blocking access, dust in the HVAC intake. Our cleanup protocol runs end-of-day, not end-of-project.
Our workmanship warranty covers what we did and how we did it. The product carries the manufacturer's own warranty on top of ours. That means your home is protected twice — by the material the manufacturer stands behind, and by the installation Forge Siding guarantees.

We had three other quotes before calling Forge Siding. The difference was the inspection — they actually walked the whole house with a moisture meter and found soft sheathing behind two panels on the north wall that nobody else mentioned. The estimate covered the sheathing repair too, so no surprise charges when demo day came. Final result is clean and tight. We'd hire them again without hesitation.
I manage a twelve-unit building in Allentown and we needed LP SmartSide on three facades before winter. Forge Siding coordinated with our property manager, worked around tenant schedules, delivered materials in two staged drops to keep the lot clear, and finished four days ahead of the original schedule. Commercial billing was clean and documented. They're on our preferred vendor list now.
We went with insulated vinyl — Forge Siding recommended the insulated backer for our exposure and the energy savings have been real. First heating season after the install, our gas bill dropped noticeably. Installation crew was professional, on time every day, and the lead installer walked me through every elevation before he called the project done.
I had a specific architectural profile I wanted for the gable ends — a shingle exposure pattern — and everyone else told me it was a custom order with a six-week wait. Forge Siding had it in stock through their regional supplier and we started within two weeks of signing. The detail work at the gable peaks is clean and exact. Not every contractor has the skill to do that level of trim work.
I'm a home inspector by trade, so I know what cutting corners on a siding installation actually looks like behind the panels. Forge Siding's work is correct — right fastener pattern, proper clearances from grade and roofline, continuous housewrap with taped seams at all penetrations. This is how it's supposed to be done and most of the crews I see in Allentown, NJ don't do it this way.
We had three bids and Forge Siding was the only contractor who physically checked the housewrap condition before quoting. Everyone else just looked at the surface. They found a section of torn WRB behind the garage bay that needed patching and included it in the estimate. When you're spending this much on an exterior, you want a company that checks the whole wall system, not just what they can see from the ground.
