"Cesar and his crew just finished a remodel of my master bathroom. This is the second major project completed in my home by CSZ (prior kitchen remodel) and once again they exceeded my expectations. Cesar worked with me along the way to come up with the perfect design to ensure all my requirements were met. He is knowledgeable and his attention to detail is second to none. The CSZ crew, Armondo and Benjamin were also a pleasure to work with. They are knowledgeable, trustworthy, and hardworking. They also did an exceptional job cleaning up at the end of each work day. My dog even loves them! I highly recommend CSZ Construction. They will most certainly be back for future projects in my home!"

Deck Maintenance FAQs, answered by experts

Whether you need a permit depends on the deck design and local regulations. Most areas mandate a building permit if the deck is over a specific height or if it's attached to a pre-existing structure. Shorter, freestanding decks may not require a permit, but you should check with local zoning ordinances and your homeowners association for specifics.

In most cases, there should be a small gap between the house and the deck, usually no more than ½ to ¾ of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the most common issues with decks.

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.

Spindles on a deck may also be called balusters or pickets. While not as important to the structural support of the deck as the rail posts, they play a critical role in ensuring the deck is safe to use by closing in large gaps in the railing. For this reason, balusters must be no more than 4 inches away from one another.

It is recommended to clean your deck once or twice a year to prevent the accumulation of dirt, debris, mold, and mildew. The ideal times for cleaning are in the spring and fall. A spring cleaning removes grime that has built up over the winter, preparing your deck for summer use. A fall cleaning washes away messes from summer activities, preventing them from setting into the wood over the winter. The exact frequency can depend on factors such as how often the deck is used, its exposure to pollen, and whether salt was used on it during the winter. Regular cleaning helps protect the wood and its finish from damage.
