Custom Deck Construction
A deck should feel solid under your feet and make sense for your yard’s layout. We build everything from simple platforms to multi-level decks designed for entertaining, grilling, and relaxing.
Material Options
- Composite decking: Composite decking is low maintenance, long-lasting, and resistant to fading and moisture, making it ideal for homeowners who want durability with minimal upkeep.
- Pressure-treated or natural wood: Pressure-treated or natural wood provides a classic look with warmth and character, perfect for those who prefer traditional materials.
We also design and install:
- Custom railings (wood, composite, or metal)
- Integrated stairs and landings
- Built-in seating
- Deck replacement for aging or damaged structures
Whether you’re hosting summer cookouts in Rockford, IL or enjoying quiet evenings in Janesville, WI, every deck is built to meet local code requirements, so you can feel confident in its safety and longevity.
Patio Installation
For ground-level outdoor living, patios offer flexibility and durability. As trusted patio installation contractors, ERS Builders creates patios that complement your home’s style and handle seasonal freeze-thaw cycles common in this region.
We focus on proper base preparation and drainage to prevent shifting, cracking, and water pooling over time. A properly installed patio protects your investment and reduces long-term maintenance issues.
Outdoor Living Add-Ons
If you’re investing in your backyard, it makes sense to build it the right way from the start.
We can incorporate:
- Fire pits for extended seasonal use
- Outdoor kitchens and built-in grilling areas
- Pergolas and shade structures
- Covered patios for protection from sun and rain
- Screened-in porches for comfort without insects
Whether you want a simple patio or a fully integrated outdoor living space, we’ll scale the project to match your goals and budget.

FAQs About Deck and Patio Construction
How much does a new deck or patio cost in Illinois or Wisconsin?
Costs vary depending on the scope of the build, material selection, elevation, and features like railings or stairs. After an on-site evaluation, we provide a free estimate so you know exactly what’s included before work begins.
Will I need a permit for my patio or deck project?
In many areas of Northern Illinois and Southern Wisconsin, permits are required for decks and patio structures, especially if they’re attached to the home or include roofing. Our team manages the permitting process and confirms requirements for your specific municipality.
How long does construction typically take?
Standard decks and patios can often be completed within one to three weeks, depending on complexity and weather conditions. Larger projects with covered patios, multi-level decks, or integrated features may take longer. We provide a clear schedule and timeline before construction begins.
What is the best decking material for Midwest weather?
In Northern Illinois and Southern Wisconsin, decking materials must withstand moisture, snow, temperature swings, and freeze-thaw cycles. Composite decking is a popular choice because it resists rot, warping, and insect damage while requiring minimal maintenance. Pressure-treated wood is more budget-friendly upfront but requires regular sealing and upkeep to protect against moisture.
We help homeowners choose the right material based on budget, maintenance preferences, and long-term performance goals.
