"I wish all categories of home improvement could have a company such as Pro Builder from Garfield. Our wooden deck was in dire need of help. It was not an easy task because the deck is approximately 20 feet above ground level from the garden area. Through the expertise, knowledge, and commitment from this company, the project was finished on schedule. Our new composite deck looks outstanding!"

"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

Wood decks need to be replaced every 10 to 15 years on average. Natural wood is highly vulnerable to infiltration and damage from moisture, which can occur rapidly due to exposure to outdoor elements. You can protect your deck and maximize its lifespan by sealing it every year or two.

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.

In many areas, a floating deck that isn’t connected to your home and stays under 200 square feet and below 30 inches in height may not need a permit. These freestanding structures are often considered low-risk, which can simplify the building process. However, building codes vary greatly based on location. Before investing in any home improvement project, check with your local permitting office for deck-building guidelines.

For the best results, stay off of your deck for at least 48 hours after sealing it. Giving the sealant at least two full days to cure ensures it can fully penetrate the wood, giving you the most protection from sun and weather damage later on. Walking on the deck too soon can prevent it from properly curing and cause your deck to weather prematurely.

Space deck handrail posts four to six feet apart. If the posts are more than six feet apart, the railing will be less able to withstand lateral forces and is more susceptible to breaking. Additionally, railing posts that are more than six feet apart may not be up to code, and you may face fines and be required to reinstall the posts to bring them up to code.
