At Kobiske Construction, we build custom decks that stand up to Wisconsin weather and everyday family life. We also see a few common mistakes on projects that could have been avoided with proper planning and support. In this guide, we share what to watch for so your next deck feels strong, looks great, and adds real value to your home.

What Is the Biggest Mistake Homeowners Make Before Hiring Deck Contractors?

One of the biggest mistakes is jumping into a deck install without a clear plan or design. You may want a simple platform, but without considering sun patterns, rainfall, or how you use your space, you could end up with a deck that gets too hot, floods easily, or feels cramped.

Before you start, ask yourself:

  • What will I use my deck for most often?
  • Do I want room for dining, grilling, or relaxing?
  • How does the sun move across my yard throughout the year?

Good deck contractors will walk you through these questions and help refine your vision.

Common Mistakes to Avoid When Building Your Deck

Skipping Proper Permits and Codes

Every Wisconsin community is different, and towns like Delafield, Johnson Creek, Oconomowoc, and Middleton have specific building codes you need to follow. A permit is not optional. Building without one can lead to fines, and at worst, you may be asked to tear out work you already paid for.

Good deck contractors know local permitting requirements and handle the paperwork for you.

Forgetting About Drainage and Sloping

If your deck sits near your home or slopes toward the house, water can pool against your siding or foundation. This leads to rot and costly home repairs later. Proper grading, drainage channels, and spacing between deck boards help water flow away from your house.

Choosing the Wrong Materials

Pressure-treated wood might seem cheap at first, but in wet Wisconsin climates, it can warp or rot faster than composite decking or properly sealed hardwood. Cedar and composite boards resist moisture better but have different care needs. Your deck contractor should walk you through the pros and cons of each.

Poor Fasteners and Hardware

Cheap nails and screws that rust will leave ugly stains and weaken joints. Use hardware rated for outdoor use, such as hot-dipped galvanized or stainless steel. It lasts longer and keeps your deck safe and sturdy.

How Do I Know if I Picked the Right Deck Contractor?

You can tell a good deck contractor by:

  • Transparent pricing and written estimates
  • A portfolio of finished projects
  • References from homeowners in communities near you, such as Hartford, Monona, New Berlin, Pewaukee, Sussex, or Verona
  • A willingness to explain steps like foundation layout, joist spacing, and railing safety

Kobiske Construction takes time to review your goals and share options that fit your style and budget.

What Extras Should I Plan For During Deck Construction?

Thinking ahead can save money later. Ask about:

  • Built-in seating
  • Lighting for evening use
  • Covered areas or pergolas
  • Stair safety lighting
  • Decorative railing styles

These details may seem small, but they add comfort and enjoyment to your deck year after year.

Extra Tips for Deck Longevity

Routine care will keep your deck looking fresh. Consider these tips:

  • Clean your deck annually with a mild soap and water
  • Seal wood decks to limit moisture damage
  • Trim plants near your deck to improve airflow and reduce rot
