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

We didn't start Forge Siding to push volume — we built it because homeowners in Lake Oswego 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 Lake Oswego, OR 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.
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.
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 OR'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 OR'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 Lake Oswego 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.

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.
Four steps. Each one documented. No surprises at the invoice.
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.
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.

We don't sub out work to unlicensed handymen to cut costs. Every installer on a Forge Siding project is a W-2 employee or licensed sub with verified credentials and completed manufacturer training.
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 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.
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.
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.
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.
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.
