"Wonderful! There was a build up of green mold and moss on screens. The pool deck had years of ground in dirt. All was cleaned to perfection leaving even the deck ready to repaint. Very reasonably priced and very professional."

Deck Maintenance FAQs, answered by experts

Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.

The cost to build a second-story deck averages $4,800, though the actual price could range as low as $420 to upwards of $16,000. While labor costs range between 35% and 50% of the total project cost, the materials and complexity of design will ultimately lead you to save or spend more money on this home addition.

Any wood deck provides some ventilation to the area below, as is the nature of that type of deck design. However, areas that experience excessive humidity and associated moisture benefit greatly from a dedicated ventilation system in the form of strip vents. This addition helps the various wood boards contract and expand evenly throughout the years and reduces the chances of twisting, warping, and buckling.

A wood deck requires annual cleaning and regular inspections for loose or broken boards, nails, and screws. It should be refinished by applying a stain or sealer every two to three years to protect the wood from water damage, rot, mildew, and sun fading. The exact frequency can depend on the climate and the deck's exposure to sun and moisture. If your deck is painted, it will need repainting approximately every 10 years. Signs that your deck needs refinishing include faded, splintering, or warping boards.

Decks are generally more expensive to build because they require elevating and railings. The difference between decks and patios is that decks are elevated, while patios are usually on the ground level. Plus, decks are usually made of wood and need more maintenance than most patios. However, decks and patios serve the same purpose, providing outdoor space for you to enjoy.
