What Homeowners Say About Warner’s Decking






Downers Grove, IL Deck Building Services

Custom Composite Deck Installation
Composite decking offers the appearance of natural wood with less ongoing maintenance. We design custom layouts around your home and outdoor space, with options for stairs, railings, lighting, seating, and other features.

Deck Replacement & Resurfacing
If your existing deck is aging or the surface needs an update, we can help determine the best approach. If the existing structure is in good condition, resurfacing can be a cost-effective way to update the deck. If the structure needs major repairs, a complete replacement may be the better option.

Wood Decks
A wood deck remains a popular choice for homeowners who want the natural appearance and character of real lumber. We can help you select the right material and design based on appearance, maintenance, durability, and budget.

Steel Deck Framing
We offer steel deck framing as a durable alternative to traditional wood framing. Steel can provide strength and long-term performance while supporting a clean, modern deck design.
