When your exterior starts failing, the clock is already ticking. Forge Siding provides full Siding in Northumberland, PA — from initial assessment to final cleanup — so your home is protected and your curb appeal restored.

We didn't start Forge Siding to push volume — we built it because homeowners in Northumberland 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 Northumberland, PA and our callback rate is under two percent. That number matters to us.

Siding doesn't fail overnight — it gives you warning signs first. Catch them early and a repair handles it. Miss them, and you're looking at rot, mold, and structural repairs on top of the siding bill.
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.
Paint peeling on your inside walls near exterior surfaces is a classic sign that moisture is migrating inward through failing siding. By the time you see it inside, the wall cavity is already compromised.
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.
Compromised siding reduces your wall assembly's thermal performance. If you've noticed climbing heating or cooling costs without an obvious cause, degraded siding — especially if it's letting air infiltrate — is worth investigating.
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.
From a single damaged panel to a complete re-side on a large commercial property, we handle the full range of exterior cladding work — and we do it with the same crew standards regardless of job size.

Fiber cement comes in lap, panel, and shingle profiles, and we've installed all three on everything from Cape Cods in historic neighborhoods to large multi-unit builds. Correct installation matters enormously with this material — improper fastening or insufficient clearances void the warranty and cause edge-swell failures. Our lead installers are trained to the spec sheet, not just to what looks right on the jobsite.

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 PA'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 Northumberland 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.
Soffit ventilation is often compromised during re-siding work when installers don't maintain existing vent openings or fail to add ventilation where it was previously missing. We verify soffit net-free vent area against attic square footage before closing up the overhang — because your roofing contractor will find the problem later if we don't.
We built our process around the two complaints we heard from homeowners most: contractors who didn't communicate, and scopes that changed after signing. Here's exactly how a Forge Siding project runs from start to finish.
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.
We schedule your project start date at contract signing and stick to it. Materials are delivered directly to the site before crew arrival — no day-of scrambling. We protect landscaping, windows, and any surfaces adjacent to the work area before the first panel comes off.
Installation follows manufacturer specs and local building code. When work is complete, the lead installer does a quality check before calling you for the final walkthrough. You inspect every elevation — we go through it with you, address anything that needs attention, and make sure the site is clean and restored before we invoice.

Every crew that works on your home carries a current contractor's license for PA, full general liability, and workers' compensation. We'll email you the certificates before we arrive — not after you ask three times.
You see the number before you sign — and the invoice matches the estimate. If scope changes come up during demo, we stop work, show you what we found, and get written approval before proceeding. No invoice surprises.
When we book your project, we commit to a start date. No bumping you for a bigger job, no weeks of silence after signing. We operate with enough crew capacity to honor the schedule we gave you.
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.
Every Siding project we complete is backed by our written workmanship warranty. If anything we installed fails due to installation error — a panel pulls loose, a trim joint opens, moisture gets in at a transition we sealed — we come back at no charge and fix it. Not a credit, not a partial. Fixed.

We were replacing deteriorated T1-11 on a house we'd bought the year before. Forge Siding walked us through why HardiePlank made more sense than vinyl for our wall orientation and explained the flashing work that needed to happen around the windows before panels went on. Project started on the date they said. Crew cleaned up every afternoon. The job came in within a couple hundred dollars of the estimate.
A storm took out a whole section of vinyl on the east side of our house. I called four contractors — three of them said they'd have to replace the entire elevation because they couldn't match the profile. Forge Siding's estimator sourced a matching panel through their supplier network and did a clean repair. You can't tell where the new material starts. Saved us probably $4,000 compared to a full-side re-do.
The fascia and soffit on our older home were rotting away and we assumed it would be a nightmare project. Forge Siding quoted it alongside the siding replacement so everything was done in one mobilization. The crew found two spots where the rafter tails had started to soften — they showed me photos before touching anything and walked me through the repair options. The whole exterior looks like a different house now.
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 Northumberland, PA don't do it this way.
I needed a quick turnaround on a rental property before a new tenant moved in. Forge Siding fit us in on short notice, did a clean vinyl replacement on two elevations, and the inspection cleared without a single callback item. Responsive, professional, priced fairly. That's all I ask for and they delivered all three.
