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 Mundelein, IL to inspect, repair, and replace with zero guesswork.
We didn't start Forge Siding to push volume — we built it because homeowners in Mundelein 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 Mundelein, IL 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.
Hairline cracks look cosmetic but they're water channels. Once moisture gets behind the panel and hits the housewrap — or finds no housewrap at all — sheathing rot starts within one season.
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.
Panels that have pulled away from the wall are an open door for pests, moisture, and cold air. Nails back out over time when the substrate is soft — often a sign of prior water damage underneath.
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.
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 is the workhorse material we recommend most in IL'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 IL'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.
LP SmartSide and similar engineered wood products split the difference between the look of real wood and the dimensional stability of manufactured products. They're primed at the factory, accept field-applied paint well, and hold up to impact and moisture better than OSB or solid wood. We use LP SmartSide Trim & Fascia alongside the panel and lap systems so the trim package matches — no mixing incompatible products that age differently.
Our repair crews use the same material standards as our full-installation teams — no caulking over gaps as a permanent fix, no missing sealant at transitions, no shortcuts on housewrap at the repair perimeter. If there's rot in the sheathing behind the damaged panel, we address it during the repair rather than covering it up.
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.
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.
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 IL, 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 Mundelein, IL 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.
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 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 Mundelein 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 Mundelein, IL 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.
