Your home's exterior takes a beating every single day — sun, wind, rain, impact. When siding fails, moisture gets in fast and damage follows. Forge Siding sends licensed Siding crews across Thornton, PA to inspect, repair, and replace with zero guesswork.
Forge Siding grew out of a simple frustration: too many Thornton homeowners were paying good money for Siding work that failed inside five years. Wrong profiles, wrong fastener gauges, no housewrap — then the callbacks never came. We do it right the first time, using manufacturer-recommended installation methods and materials rated for PA's specific climate demands.
Our crews are licensed, carry full general liability and workers' comp, and every lead installer has completed manufacturer certification training. We work with fiber cement, engineered wood, vinyl, and steel systems — and we'll tell you straight which one makes the most sense for your home's structure, your local weather patterns, and your budget. No upselling, no pressure.
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.
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.
Extreme fading means UV degradation — the protective surface layer is gone. Chalking on older paint-based systems signals the same. At that stage, the panel is no longer blocking UV penetration to the substrate underneath.
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 PA'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 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 Thornton 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.
The estimate covers every line item — material, labor, disposal, permit fees if required in your jurisdiction. You pick the product, the profile, and the color with our input on what's going to perform best for your specific wall orientation, climate exposure, and substrate condition.
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.
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 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.
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.
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.
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 Thornton, 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.
