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

Forge Siding grew out of a simple frustration: too many Islip 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 NY's specific climate demands.
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 Islip, NY 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.
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.
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 NY'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 NY'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 Islip 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.
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.
A thorough inspection before we quote means the estimate we hand you is accurate. We check the substrate, the existing housewrap or vapor barrier, window and door flashing, corner and soffit condition — all of it — so there are no hidden surprises once demo starts.
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.
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.
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 NY, 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 Islip, NY on the fact that our estimates are reliable.
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.
Old siding demo generates a lot of debris — old panels, nails, housewrap, fasteners. We haul it out daily. Your driveway, lawn, and landscaping are clean at the end of every work day — not just at project completion.
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.
Talk to Us About Your Project — +1-844-782-0929We don't cherry-pick — these are verbatim accounts from homeowners who hired us for Siding work across Islip, NY.
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 Islip 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.
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.
The estimate process was refreshingly honest. The estimator told me upfront that my old OSB sheathing had delaminated in two areas and would need replacement before new siding could go on — with photos and a written line item. No one had mentioned that in the other quotes. Forge Siding fixed the sheathing, installed the HardiePanel system, and the project cost exactly what they quoted including the repair.
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 Islip, NY 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.
