Durable Custom Deck Construction for Michigan Weather in Genesee County

Decks in Michigan take a beating from snow, ice, moisture, and temperature swings. As a custom deck builder Genesee County MI homeowners rely on, we plan and build decks with materials and construction methods suited for long-term durability.


We build both composite decks and traditional wood decks, and we help homeowners understand the differences before choosing. Layouts range from simple attached decks to larger multi-level designs that follow the slope of the yard and connect indoor and outdoor living spaces.

Our Custom Deck Building Process

Design Consultation & Material Selection

Every deck project starts with a discussion about how the space will be used.


We look at access points, yard layout, sun exposure, and how the deck will connect to the home.


From there, we help review layout options, railing styles, and material choices.


We explain the pros and cons of composite decking, including Trex-style products, compared to traditional wood.


Maintenance expectations, appearance, and long-term durability are all part of the decision.

Permitting & Site Preparation

Most decks require permits and inspections.


We manage the permitting process and coordinate required inspections with local building departments across Genesee County.


Site preparation includes verifying footing locations, elevation, and attachment details so the deck meets code and remains structurally sound.

Professional Installation & Multi-Level Construction

Once construction begins, we coordinate licensed trade partners as needed and manage the installation process.


Framing, decking, railings, and stairs are installed in the correct sequence, with attention paid to load requirements and drainage.


For multi-level decks, careful planning ensures proper transitions, safe stair placement, and long-term stability.

Final Inspection & Maintenance Guidance

After construction is complete, we review the finished deck and address any remaining details.


We also walk through basic maintenance expectations based on the materials used.


This way, you know how to keep the deck in good condition over time.

Popular Deck Styles & Materials for Genesee County Homes


Composite & Trex Decks – Low Maintenance


Composite decking, including Trex-style products, is a popular choice for homeowners who want a low-maintenance option.


These materials resist rot, splintering, and moisture damage, making them well-suited for Michigan weather.


Composite decks require less upkeep than wood and maintain a consistent appearance over time.


Traditional Wood Decks – Classic Look


Wood decks remain a good option for homeowners who prefer a natural appearance.


With proper construction and maintenance, wood decks can perform well, though they typically require more ongoing care.


We explain material options and maintenance expectations upfront so homeowners can make informed decisions.


Multi-Level & Attached Deck Designs


Multi-level decks work well on sloped properties or when connecting different living areas.


Attached decks create a seamless transition from interior spaces to the outdoors, expanding usable living space during warmer months.


Design is focused on safety, flow, and how the deck will be used day to day.
