Commercial Deck Design That Works for Your Business
A commercial deck installation is not the same as a residential one. It needs to work harder, hold up longer, and fit the way your business actually operates.
Before we build anything, we come to your property and look at how your space is used. How many customers do you need to seat? Where do staff need to move through? Are there drainage concerns? Are there load requirements based on your occupancy? We ask the right questions upfront so the design works in real life, not just on paper.
From there, Amy creates a custom 3D design of your specific property. You will see exactly how the finished deck looks, how the layout flows, and how materials fit your building before we start any work. Every commercial deck installation we do is planned this way. No surprises.
Materials Built for Commercial Use
The materials that work fine on a backyard deck are not always the right choice for a commercial property. Commercial decks take more foot traffic, more wear, and more exposure than residential builds. We use materials that are up to that demand.
For commercial composite deck installation, we use Timbertech Advanced PVC.

Here is why it works well for businesses:
- 100% PVC with no wood fibers, so it will not rot, splinter, or absorb moisture
- Handles heavy foot traffic day after day without breaking down
- Available in 15 colors so it can match your building's look
- Needs only occasional soap and water cleaning, no staining, no sealing, no sanding
- Minimal maintenance means less downtime and fewer ongoing costs for your business
Framing That Holds Up Under Commercial Load
The surface of your deck is what customers see. The framing underneath is what determines how long it lasts and how safe it is under daily commercial use.
We frame every commercial deck with KDAT lumber, which stands for Kiln Dried After Treatment. Standard pressure treated framing lumber is wet when it leaves the treatment facility. Over time it shrinks, warps, and twists as it dries. On a commercial property with heavy use, that kind of structural movement causes problems faster.
KDAT is dried before it arrives on your job site. It is already dimensionally stable when we install it.
The result:
- Framing that stays straight under load
- Joints that do not separate over time
- A deck structure that performs consistently year after year
- Fewer repair calls and less long-term maintenance
This is the standard we hold every commercial deck installation to, not an upgrade you have to ask for.


Commercial Deck Repair in West Allis
Not every commercial project is a new build. If your existing deck is showing wear, structural issues, or surface damage, we can assess it and repair it properly.
Common commercial deck repair work we handle includes:
- Replacing warped, cracked, or damaged deck boards
- Fixing structural framing issues including joists, beams, and ledger connections
- Repairing or replacing railing systems that no longer meet code
- Addressing drainage problems that cause standing water or surface deterioration
- Upgrading older wood surfaces to Timbertech Advanced PVC composite decking for lower long-term maintenance
If your deck needs repair, we will come out, look at what is actually wrong, and give you an honest assessment. Sometimes a targeted repair is the right move. Sometimes a full replacement is the better investment. We will tell you which one makes more sense for your situation.
Railing Systems for Commercial Properties
Railings on a commercial deck need to meet safety codes and hold up under constant use. We offer options built for exactly that.
- Westbury aluminum railings are rust-proof, low maintenance, and available in multiple colors to fit your building's exterior
- Fortress steel railing systems offer superior strength with powder-coated finishes that resist fading and weathering under heavy use
- Dan's custom fabricated steel railings are built by hand for businesses that want a distinctive look, decorative screens, geometric patterns, and one-of-a-kind designs that set your property apart
All railing installations meet applicable safety and building code requirements for commercial properties.
