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 Northbrook property — crews who diagnose the actual problem, price it in writing, and fix it once.

Forge Siding has been delivering Siding across Northbrook, IL 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.
We work across the full project range: single-panel storm repairs, complete whole-home re-siding, new construction cladding alongside general contractors, and commercial multi-family projects for property managers who need consistent quality and documentation across multiple buildings.
Every Forge Siding project closes with a signed workmanship warranty document. Not a verbal commitment — an actual document with coverage period, covered defects, and a resolution process you can hold us to. Manufacturer material warranties are registered in your name at project completion, so the coverage that came with the product stays in force.

These are the signals that experienced crews look for on every Northbrook, IL property inspection. Missing them is how a $400 repair becomes a $4,000 wall reconstruction.
Hairline fractures look cosmetic. At arm's reach they look different — especially on fiber cement where surface spalling around impact points creates moisture entry that accelerates sheathing damage.
Drywall staining, soft spots when you press near exterior walls, or a persistent musty odor in exterior-adjacent rooms are downstream indicators. The sheathing has usually been wet for weeks before these symptoms appear.
Warped wood siding typically means unpainted back faces — differential expansion between the painted front and the raw back causes curvature that worsens with every moisture cycle.
Exterior paint failing within two to four years of application on wood or fiber cement is almost always a back-priming failure — moisture migrates through the panel from behind and pushes the front paint off. Re-painting without addressing this repeats the cycle.
Dark streaking from nailhead locations on vinyl or fiber cement means non-galvanized fasteners are corroding. As the fastener degrades, its holding strength decreases — a panel secured by a corroded nail is a panel waiting to separate in a windstorm.
A compromised siding system — failed housewrap, open panel joints, missed penetration caulk — creates air infiltration that significantly increases HVAC load. If your heating or cooling costs have climbed without obvious explanation, the building envelope is a legitimate first suspect.
Our Northbrook, IL team handles the full spectrum of residential and commercial cladding work from single-panel storm repairs to complete building envelope re-siding on large multi-family properties.
Installation quality is the variable that separates a 15-year siding job from a 35-year one. The correct expansion gap for your IL climate, the proper back-priming of fiber cement field cuts, the housewrap integration at rough openings — these details determine long-term performance and they aren't optional on our projects.
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.

Siding repair in Northbrook, IL covers a range that extends well beyond swapping a cracked panel: hail and wind damage after storms, impact holes from debris or vehicle contact, failed caulk joints at penetrations allowing water infiltration, loose or blown-off panels, and moisture-infiltrated substrate that requires sheathing repair before new cladding can go on. Our Northbrook, IL repair crews carry common panel stock, a moisture meter, and caulk probe tools on every service truck — so assessment and often same-day repair happen in a single visit.
For insurance-related damage, we produce a panel-level photo documentation package — close-range images by elevation, written damage scope, and material specifications formatted for adjuster review. After the initial adjuster estimate comes in lower than the actual scope, our documentation has supported successful appeals on a significant number of Northbrook, IL claims. That documentation service is included in every storm inspection at no additional charge.

Each cladding material has distinct installation requirements that determine whether it performs for 10 years or 40. Our Northbrook, IL crews hold certifications specific to the products they install — not one generic approach applied to every material. Fiber cement installation requires back-priming at every field cut, hot-dipped galvanized or stainless fasteners, documented fastener schedules per the manufacturer guide, and silica dust controls during cutting operations. Vinyl installation requires expansion gaps calibrated to the local temperature range in IL. Wood siding requires moisture content verification at delivery, species-appropriate nailing patterns, and end-grain sealing at every butt joint. We address each of these requirements as non-negotiable installation practice.
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 Northbrook, IL property owners recover claim settlements that significantly exceeded initial adjuster estimates by providing specific, photo-verifiable panel-count documentation rather than general damage descriptions.

Commercial siding in IL operates on different requirements than residential: higher fastener schedules for wind-load compliance, special inspection documentation in applicable jurisdictions, coordinated scheduling for occupied buildings, and standardized documentation for HOA board records and reserve fund planning. Our commercial crews are familiar with the permitting landscape in IL and have completed projects ranging from small townhome communities to larger multi-family re-siding contracts.

These aren't aspirational claims. They're the operational standards our Northbrook, IL clients reference when they send us referrals. Each one is documented and verifiable.
Materials, labor, permit fees, and disposal listed separately on every estimate. You know exactly what you're paying for before signing. The estimate becomes the contract, and the final invoice reflects it — no lump-sum numbers we can pad quietly.
Our IL 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 Northbrook's specific code requirements.
An unlicensed contractor on your property creates liability exposure for you personally. License verification before signing eliminates the most common contractor fraud scenario in the Northbrook, IL market.
Every completed project closes with a signed warranty document: coverage period, covered defects, and the resolution process — all specified in writing. Manufacturer warranties registered in your name at project completion. Not a verbal promise; a document you can file, reference, and enforce.
A crew that leaves a clean site every evening is a crew that respects the property they're working on. We treat cleanup as part of the daily schedule, not a last-day obligation.
You don't have to call us to find out where your project stands. We tell you, every day, in writing.

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.
We manage a 34-unit townhome community. The per-building documentation, the building-by-building scheduling, the HOA board close-out package — these are things I'd been trying to get from contractors for years and never received until Forge Siding.
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.
The daily morning and afternoon updates from the lead installer were something I hadn't expected. I always knew exactly where the project stood. When the permit inspection happened, I heard about it the same day it passed.
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.
