St. Charles weather throws a lot at your deck—rain, freeze-thaw, and shifting soil. We design for it all. Our framing, footings, and layouts are built to last in this environment. Whether you're along the river or up near New Town, we tailor every build to the lot and the rules.

How Can We Help?
From grilling and lounging to safe access and flow, we design for how you actually use your space. Your deck should feel like it belongs—not like it was added later. We plan for traffic, railings, shade, and seating, all while meeting code and HOA guidelines.
Designed for St. Charles slope and drainage
Composite and wood options available
HOA-ready drawings and permit support

We’ve worked across St. Charles—from the Bluffs to Charlestowne—and we know the permit process, zoning rules, and HOA requirements. Our plans are detailed, clear, and code-ready. You get peace of mind knowing the paperwork, inspections, and approvals are handled from day one.

We don’t just meet code—we build to exceed it. Deep footings, spaced joists, and sealed fasteners protect your deck from movement and moisture. Whether you're on a flat backyard or sloped riverside lot, your frame is built to hold up through every season.
We install top-rated composite from Trex and TimberTech or classic wood like cedar and treated pine. Each material we use is selected for long-term durability, climate performance, and visual appeal. We’ll help you pick the right fit for your lifestyle and maintenance preferences.


New Town: With water features and strict HOA rules, New Town decks must be clean, code-perfect, and blend with architecture. We handle designs that get approved.

Charlestowne: From walkout basements to second-story views, Charlestowne homes are great for multi-tiered decks and integrated shade features.

The Bluffs: Large wooded lots make The Bluffs ideal for elevated decks, privacy rails, and wide staircases that blend into natural surroundings.

We’ve worked across the city, and the questions are usually the same—how long will it take, what material works best, and what’s the permitting process like? Here are a few of the most common questions we answer before breaking ground.
Yes. We submit all plans to the city and handle inspections. Every build meets current code and setback rules.
Composite performs best with minimal upkeep. Cedar works well too if sealed every few years. We offer both.
If the frame passes inspection, yes. We offer re-decking when it’s safe—and we’ll recommend a full rebuild if it’s not.
Absolutely. We create code- and HOA-ready plans with all necessary drawings and specs to get approvals quickly.
