Our Deck Building Services in St. Charles County
We offer a wide range of custom deck construction and related services for homeowners across St. Charles County.
Multi-Level Deck Design
Add dimension to your yard with a multi-level deck design—great for entertainment zones, hot tubs, or terraced gardens. In hilly areas like Augusta or Foristell, multi-level decks make the most of sloped lots.
Elevated Deck Installation
Need a deck for a sloped yard or raised foundation? We specialize in elevated deck installation with strong framing and structural support. Elevated decks are common in Lake St. Louis and New Melle, where uneven terrain is a factor.
Pressure-Treated Wood Decking
For a budget-friendly, weather-resistant option, we build decks using pressure-treated wood decking that’s safe, sealed, and long-lasting. This is a great option for rental properties or homes that need quick, affordable upgrades.
Deck Railings and Stairs
Safety meets style with our custom deck railings and stairs. We build to code and offer a variety of design options. Choose from metal, wood, or composite railings that match your deck’s style and your home's exterior.
Deck Refinishing Services
Is your old deck showing signs of wear? We offer deck refinishing services to restore color, texture, and protection. We can power wash, sand, and stain old decks, bringing them back to life without a full rebuild.
Outdoor Living Space Design
We design full outdoor living spaces with decks, patios, and seating areas that blend beauty and function. Want a grill area, built-in seating, or a pergola with lighting? We’ll build it.
Pergola and Shade Structures
Create a shaded retreat with our custom pergola and shade structures. Stylish, sturdy, and perfect for summer relaxation. Shade structures help extend your deck’s usability into hot afternoons and rainy days.
