Why Homeowners in West Chicago Choose Us for New Deck Construction

Most "deck builders" are general handymen who build decks on the side. We're not. Deck design and construction is a core service, which means three things matter to you:

• Structural engineering, not guesswork. Every deck we build is sized to local code, inspected, and engineered for the load — including snow, hot tubs, and outdoor kitchens if that's in the plan.
• Material guidance you can trust. We'll talk you through composite vs. PVC vs. wood honestly. The most expensive option isn't always the right one for your house, your budget, or how you actually use the space.
• One crew, one timeline, one warranty. No subcontracted strangers. The team that starts your deck finishes it, and the workmanship warranty is in writing.

Decking Materials We Build With

Choosing the material is the single biggest decision in any new deck project. Here's how the three main categories actually compare.

Composite Decking

Composite boards (wood fibers + recycled plastic) are the most popular choice for new construction in Illinois because they handle humidity, won't splinter, and never need sanding or staining. We build with TimberTech, Trex, and Fiberon — all with 25+ year warranties.

• Best for: homeowners who want a beautiful deck and zero maintenance
• Typical lifespan: 25–30 years
• Maintenance: occasional soap-and-water wash

PVC (Capped Polymer) Decking

100% synthetic — no wood content at all. The premium tier. Lightest, coolest underfoot, and the most stain- and scratch-resistant option on the market.

• Best for: pool decks, full-sun exposures, coastal builds
• Typical lifespan: 30–50 years
• Maintenance: rinse with a hose

Pressure-Treated & Hardwood Decking

Natural wood still has a place. Pressure-treated pine is the budget-conscious option; cedar, ipe, and mahogany are for homeowners who want the look and feel of real wood and don't mind the upkeep.

• Best for: traditional aesthetics, lower upfront budget
• Typical lifespan: 10–20 years (pressure-treated), 25+ years (hardwoods)
• Maintenance: clean and re-seal every 1–3 years

Our New Deck Construction Process

1. Free On-Site Design Consultation

We come out, measure, talk through how you actually want to use the space, and bring material samples. Usually 45–60 minutes.

2. Design & Written Proposal

You get a scaled drawing and a line-by-line proposal — materials, labor, permits, timeline. Nothing hidden in "miscellaneous."

3. Permits & Engineering

We pull every required permit in West Chicago and handle the inspections. If your build needs stamped engineering drawings, we coordinate that too.

Frequently Asked Questions About New Deck Construction

Do I need a permit to build a deck in West Chicago?

Yes, in virtually every jurisdiction in Illinois, any deck attached to the house — and most freestanding decks over 30 inches off the ground or larger than a certain footprint — requires a permit and inspection. We pull the permits as part of every project so you don't have to.

How long does it take to build a new deck?

Most residential decks take 1–3 weeks of active construction once permits are issued. Larger or multi-level builds can run 4–6 weeks. Weather and inspection schedules are the most common variables.

What's the best decking material for Illinois weather?

For most homeowners, capped composite is the sweet spot — it handles freeze-thaw cycles, humidity, and UV without splintering, fading badly, or needing annual staining. PVC is a step up in performance for pool decks and full-sun exposures. Natural wood is still a great choice if you love the look and don't mind the upkeep.

Can you build over an existing deck or do you have to tear it down?

In most cases, building over an existing structure isn't recommended — old framing usually doesn't meet current code, and you can't inspect what's underneath. We almost always recommend a tear-out and proper rebuild. It's also often cheaper than people expect, because demo is a small fraction of total project cost.

How long will my new deck last?

With proper construction and the right materials: 10–20 years for pressure-treated wood, 25–30+ years for composite, and 30–50 years for PVC.

Do you offer financing?

Yes — we partner with [financing partner] to offer fixed-rate financing with same-day approval on most projects. We'll walk through options at the consultation.

Are you licensed and insured?

Yes. Osnova Construction is fully licensed in Illinois and carries general liability and workers' comp insurance. We're happy to provide certificates of insurance before any work begins.
