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

Forge Siding grew out of a simple frustration: too many Castle Rock 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 CO'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 Castle Rock, CO 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.
Panels that bow outward have usually absorbed moisture or were installed without adequate expansion clearance. Warped vinyl or fiber cement can't seal properly at the joints, so the problem accelerates.
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.
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 CO'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.

Vinyl offers the widest color and profile selection of any cladding material, and with the right thickness and a quality insulated backer option, it performs well across most of Castle Rock, CO. We carry Dutch lap, beaded, board-and-batten, and shake profiles and can match existing siding profiles on partial replacements when the rest of the home is in good condition.

Engineered wood is popular in Castle Rock 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.
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.
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 CO, 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 Castle Rock, CO 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 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.
Five-star work across the board. The crew showed up when scheduled, worked efficiently, and the lead walked me around the house at the end of each day so I could see progress and raise any questions before the next morning. The final product is outstanding — tight lap lines, perfect miters at the corners, no nail pops. My neighbor has already asked for Forge Siding's contact information.
We had three bids and Forge Siding was the only contractor who physically checked the housewrap condition before quoting. Everyone else just looked at the surface. They found a section of torn WRB behind the garage bay that needed patching and included it in the estimate. When you're spending this much on an exterior, you want a company that checks the whole wall system, not just what they can see from the ground.
We get these questions every week. Here are the honest answers.
