How to Build Composite Decks in Stillwater

Written by

Composite decks are quickly becoming a favorite for homeowners in Stillwater. Why? Because they look great, last long, and don’t need much maintenance. If you’re thinking about building a composite deck, this guide is for you.

We’ll walk you through the process, step-by-step, using simple language and short tips. Whether you’re a DIY fan or hiring a contractor, you’ll find everything you need to get started.

What Are Composite Decks?

Composite decks in Stillwater are made from a mix of wood fibers and recycled plastic. They look like wood, but they last much longer.

Unlike wood, composite boards don’t rot, warp, or splinter. They’re also resistant to bugs and don’t need staining or sealing. That makes them a smart choice for the Stillwater climate, where temperatures and moisture can vary.

Why Build a Composite Deck?

There are plenty of reasons to choose composite decks in Stillwater:

  • Low maintenance: No need to stain, seal, or paint every year. Just clean it now and then.
  • Durable: Composite boards can last 25-30 years or more.
  • Safe: No splinters or sharp edges.
  • Eco-friendly: Many brands use recycled materials.

If you want something strong, beautiful, and easy to take care of, composite decks are a great option.

Plan Your Deck

Before anything else, you need a plan.

  • Measure the space. How big do you want your deck to be?
  • Think about shape. Square? Rectangle? Wrap-around?
  • Check local rules. In Stillwater, building permits may be required for decks over a certain height.
  • Consider features. Built-in seating? Railing? Stairs? Lighting?

Draw a rough sketch. It helps you (and your builder) stay on track.

Choose the Right Composite Materials

Not all composite decking is the same. Some are more expensive but offer better texture, color, and performance.

Popular brands for composite decks in Stillwater include:

  • Trex
  • TimberTech
  • Fiberon
  • AZEK

Visit a local dealer or hardware store. Feel the boards in person. Look at color samples in sunlight. Pick what matches your home and taste.

You’ll also need:

  • Decking boards
  • Framing materials (wood or metal)
  • Hidden fasteners
  • Railing kits (if needed)

Prepare the Site

Now it’s time to get your hands dirty.

  • Clear the area. Remove grass, plants, or debris.
  • Level the ground. This helps with stability.
  • Mark out the layout. Use string lines and spray paint.

Next, you’ll dig footings. These are holes filled with concrete that support your deck’s frame. Stillwater’s frost line is around 42 inches deep, so make sure your footings go below that.

Let the concrete cure fully before building on top.

Build the Frame

Your frame is the backbone of the deck. It holds everything together.

Use pressure-treated lumber or metal framing systems. Wood is cheaper, but metal lasts longer.

Steps to build the frame:

  1. Install beams and posts on your footings.
  2. Add joists – these go across the beams and support your boards.
  3. Double-check spacing – most composite decking needs joists every 12-16 inches.
  4. Make sure everything is level and square.

Take your time here. A strong frame makes for a strong deck.

Install the Decking

Now comes the fun part: laying the boards.

  • Start at the edge of your deck.
  • Use hidden fasteners for a clean, smooth look.
  • Leave a small gap (⅛ to ¼ inch) between boards. This allows for drainage and expansion.
  • Cut boards to fit around posts or edges.

Work slowly. Make sure each row is straight before moving to the next. Double-check measurements.

Add Finishing Touches

Once the boards are down, you’re almost done.

Add:

  • Railing – for safety and style
  • Skirting – to hide the space under the deck
  • Steps – if your deck is raised
  • Lighting – solar or wired deck lights look great at night

You can also add planter boxes, benches, or a pergola for a custom look.

Clean Up and Enjoy

After everything is installed, give the deck a quick wash. Use water and mild soap to remove dust and debris.

Now you’re ready to enjoy your new space.

Invite friends over. Fire up the grill. Sit back with a cold drink. Your composite deck is ready to shine – and it’ll stay beautiful for years.

Maintenance Tips for Composite Decks

While composite decks in Stillwater are low-maintenance, they still need some care.

  • Clean twice a year – spring and fall are ideal.
  • Use a soft brush – avoid metal or wire brushes.
  • Avoid harsh chemicals – soap and water usually do the job.
  • Remove leaves and dirt – prevents mold or stains.
  • Check for loose screws or boards once a year.

Avoid dragging heavy furniture or sharp items across the surface. This helps prevent scratches.

Cost of Building Composite Decks in Stillwater

Prices can vary, but here’s a rough breakdown:

  • Materials: $8 to $15 per square foot
  • Labor (if hiring): $10 to $20 per square foot
  • Extras (railing, lights): $500 to $2,000

So for a 300-square-foot deck, you might spend $5,000 to $10,000 depending on the design.

Remember, while composite costs more upfront than wood, it pays off long-term with less maintenance.

Why Choose a Professional?

DIY is fun, but sometimes it’s better to hire a pro.

A professional knows local building codes, has the right tools, and can finish faster. In Stillwater, many homeowners trust local contractors for composite deck builds.

Look for licensed, insured, and experienced builders. Check their past work. Read reviews. Ask questions. A good builder will walk you through everything and help you stay within budget.
