"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

The proper height for a stair riser or deck step is between four and seven inches, with seven inches often considered the most comfortable. Building your stairs to this height ensures a strain-free step position and minimizes the risk of trip and fall injuries. For optimal safety and comfort, especially on deck stairs, a rise of around seven inches should be paired with a tread depth (or run) of at least 10 to 12 inches. While it is possible to design stairs with risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. Always check with your local building codes, as they may mandate specific dimensions that differ from these general recommendations.

DIY staining or painting is manageable with proper preparation, including safety measures, necessary tools, and adherence to safe weather conditions for application.

Local building codes don’t specify the number of steps a deck can have before a railing is required, mainly because stair height varies widely. Most areas require decks 30 inches or higher to have a railing. While not exact, that roughly equates to four to seven steps.

There are a variety of second-story deck privacy ideas depending on your budget and aesthetic. For starters, you might consider fencing or tall privacy railing that masks a good portion of the open deck. A pergola or an awning can provide additional cover and shade. Outdoor curtains are an easy way to add or remove privacy at your convenience, plus they’re a wallet-friendly way to decorate your deck.

The proper and most comfortable height for a deck stair riser, also called a step, is between four and seven inches. A height of seven inches is often considered ideal for a strain-free step that minimizes the risk of trips and falls. While it is possible to have risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. For optimal safety and comfort, pair a seven-inch riser with a tread depth (or run) of at least 10 to 12 inches. Always check your local building codes, as they may have specific requirements that differ from these general recommendations.
