Stop By Our Showroom!
Picking materials from online photos doesn't work. You need to see colors in real light and feel the difference between products.
Our showroom gives you the chance to see materials in person before making a decision. You can view every TimberTech Advanced PVC color under real lighting, compare the feel and finish of Westbury aluminum and Fortress steel railings, and see Dan’s custom metalwork for ideas beyond standard railing options.

Residential Decks for West Allis Properties
West Allis backyards aren't all the same, and cookie cutter deck designs don't work here. Some properties have room for big multi level builds. Others need smart layouts that maximize smaller lots. We customize every
West Allis deck installation project around how you actually use outdoor space.
Materials built for Wisconsin weather:
- Timbertech Advanced PVC survives harsh winters without cracking or fading
- KDAT framing stays straight through freeze thaw cycles while regular treated lumber warps
- Westbury aluminum railings never need painting or rust treatment
- Camo hidden fasteners keep surfaces clean without visible screws
Traditional pressure treated framing shrinks and twists through our winters. We use KDAT lumber that's already dimensionally stable when installed. That's the difference between decks that stay level for 40 years versus ones that develop sags in 10.

Your home has its own character. Bungalow near Greenfield Avenue, ranch around State Fair Park, split level off National. We design decks that match your architecture, not templates slapped on every property.
Commercial Decking for West Allis Businesses
West Allis businesses need outdoor spaces that are built for daily use, steady foot traffic, and Wisconsin weather. Whether you own a restaurant, bar, brewery, retail space, office, or hospitality property, a well-built commercial deck can add usable square footage and create a better experience for customers, guests, and employees.
Commercial deck projects in West Allis require more than a nice design. They need proper planning, durable materials, safe layouts, and code-conscious construction from the start.
Commercial deck features we can build around:
- Outdoor dining and seating areas
- Bar and brewery gathering spaces
- ADA accessible routes and transitions
- Durable railings and stairs
- High-traffic deck surfaces
- Layouts for customer flow, service access, and outdoor amenities
Porch Installation
West Allis has serious architectural variety, and porches need to match that character. Historic bungalows, post war ranches, newer builds. We are the West Allis porch builders that honor your home's era and style, not generic add ons that look obviously tacked on.
Popular porch types:
- Front porches boost curb appeal and provide covered entries
- Screened porches solve the summer mosquito problem
- Three season porches extend living space from April through October
Porches tie into your home's structure and roofline. Poor installation causes leaks or looks like an afterthought. We handle proper flashing, ledger attachment, and trim work that makes new construction blend seamlessly with existing architecture.
