A Deck Is An Investment In How You Live At Home

You might be replacing an old deck that’s falling apart. Or maybe you’re building one for the first time. Either way, you’re looking for more than just a structure; you want something solid, safe, and built for everyday life.

That’s what this is about.

Your backyard shouldn’t feel like wasted space. It should feel like part of your home, a place to gather with friends, spend time with family, or just catch your breath after a long day. When you’re ready to build that kind of space, we’re here to help.

We build custom decks across Belvidere, Garden Prairie, Poplar Grove, Cherry Valley, and the surrounding area, always with your lifestyle, safety, and long-term value in mind.

Materials That Work for You

Composite options, such as Trex and TimberTech, give you more time to enjoy your deck and less time spent maintaining it. You get a deck that stays beautiful for years.

Designed for Your Lifestyle

Whether it’s quiet mornings with coffee or big weekend gatherings, your deck will fit the way you live, not a generic layout pulled from a catalog.

Built to Be Safe and Solid

You deserve peace of mind. Every board is installed to code (and then some), so you never have to worry about loose railings, soft spots, or safety issues down the line.

A Smooth Process from Start to Finish

You’ll always know what’s happening, when it’s happening, and who’s doing the work, so you can relax and actually enjoy the process.

Deck Building FAQs

The price depends on a few key things: the size, height, materials, and upgrades you choose. A simple pressure-treated wood deck starts around $6k–$8k, while a premium composite deck with aluminum railings and extras can go north of $50k.

We’ll walk you through options that make sense for your home and budget, and you’ll get a clear quote after the on-site consultation.

Composite decking (like Trex or TimberTech) doesn’t rot, splinter, or fade like wood, and it requires way less maintenance.

Wood can be a great choice too, especially if you’re going for a certain look or on a tighter budget. We’ll help you weigh the pros and cons based on how you want the deck to look, how much time you want to spend maintaining it, and how long you plan to stay in the home.

We’re NADRA-certified deck inspectors, which means we build to a higher standard, not just the minimum code.

Every post, beam, and board is installed with long-term safety in mind. Whether it’s your kids running around barefoot or friends leaning on the railing at a party, we make sure your deck is rock solid.

Once we’ve finalized the design and permits are in place, most decks take 1–2 weeks to build, depending on complexity and weather.

Our goal is to keep your project moving without sacrificing quality. You’ll always know what to expect and when we’ll be there, communication is a big deal to us.

Yes, most towns and counties in our area (like Belvidere, Poplar Grove, or Cherry Valley) require permits for new deck construction.

The good news? We take care of that for you. We’ll handle all the code requirements and paperwork so you don’t have to stress about the red tape.

Every deck we build is custom, designed around your home, your yard, and how you want to use the space.

Want a wraparound layout, a sunken hot tub, or built-in lighting? We’ve got you. You’ll never get a cookie-cutter deck from us, because your home deserves better.
