A new deck can both add value to your home and be a less expensive way to increase your living space. The cost of your deck is directly related to the amount of functionality and design type.

Deck Materials

Some deck materials require almost no ongoing maintenance, but you'll pay for this luxury. Less expensive materials make a fine deck but maintaining it requires ongoing cleaning and sealing to avoid rotting and color changes. Here are some of the most popular deck materials:
  • Pressure-treated Wood: an affordable, long-lasting and hardy material great for locations with high moisture.
  • Cedar and Redwood: slightly more expensive materials that are durable and take stains well.
  • Composite Wood and Plastic: appears to be real wood, without worrying about rotting, shrinking and splintering. These materials are easy to clean and maintain but are more expensive than regular wood.
  • Vinyl: the perfect solution for a low maintenance homeowner but the most expensive.
  • Deck Size

    Most deck builders charge per square foot. Materials are also purchased per square foot. If you want a large or elaborate deck, you will spend quite a bit more than for a small platform. It comes down to functionality. If you want to do more than sit on your deck, then your budget will increase.

    Special Features

    You can stop building your deck once you have a platform, but where's the fun in that? Get creative with your special features: a built-in storage for keeping toys out of site, misting systems for keeping cool, a grill for summer barbecues. These features will make your space more usable. You will also want to factor in the cost of outdoor furniture and landscaping the area around the deck to make everything look polished.

    Preventing Landscape Damage

    Once your deck project commences, there will be a lot of foot traffic and materials lying around your yard. You will want to prepare your yard to avoid damage to your landscaping. Spending a little time at the beginning of the project will help you mitigate any additional costs to fix the landscaping once your deck is complete.
