What Sets Siding Unlimited Apart From Other Deck Builders?

When you turn to the decking contractors at Siding Unlimited, we’ll help you pick the perfect deck design that will best suit your home and any lifestyle requirements you may have. As soon as that’s finished, we’ll send out our deck builders to complete your project. We have many decks to choose from such as:

  • Composite decks – Our composite decks look just like wood to give a luxurious feel and are protected with a polymer cap to keep out moisture and lock in color. We’ve partnered with TimberTech, an industry-leading composite deck manufacturer, to provide you with gorgeous decks that will last you for years to come.
  • Pressure-treated wood decks – These real wood decks are made to be finished, stained, or painted to suit your aesthetic preferences. They also resist the effects of fungal decay, rot, and termites.
  • Cedar decks – When fully weathered, cedar decks take on a silver-gray color that many homeowners love. Beautiful cedar decks naturally contract and expand with moisture levels in the air to prevent twisting, curling, or warping due to water damage. Cedar also resists rot, decay, and insect infestation.

No matter what decking material you choose, you can rest easy knowing your deck is backed by a fade and stain warranty for up to 50 years.
