"JM turned a beat up, large backyard deck into a gem. Easy to work with and can offer suggestions of different aspects of the project. They took great care with a wisteria we've had for years that has wrapped around a portion of the deck's railing. I would definitely hire this company again."

"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!"

"We had an issue with a leak in our roof. Called and talked to Spiro. He came out the same day and took a look at it. In a short period of time Chico had it fixed and did a super job. They were both timely, professional and got the job done right. I highly recommend this company. Thank you for being a company I can depend on. I will definitely call them in the future."

Deck Maintenance FAQs, answered by experts

Pressure-treated wood contains preservatives that give the material internal protection from rot and pests. Untreated lumber won’t last more than a few years unless you choose a more expensive wood, like cedar, that naturally stands up well to moisture. Composite decking can outlast wood but is more expensive and doesn’t look as natural. Keep in mind that you’ll need to seal any exterior wood product to protect it from the elements and other forms of external damage.

Many composite decking manufacturers, including the popular Trex brand, offer warranties that protect against warping under specific conditions. These warranties typically last between 20 and 50 years, but they usually exclude claims related to improper installation of the product. Some manufacturer warranties only cover decks built by certified professionals.

Your deck may pop, and your neighbor’s deck may not for a number of reasons. Whether or not a deck pops will depend on how it was made, the conditions it’s exposed to, and the materials. Improper spacing is a common reason for increased pressure between deck boards. Moisture penetration is another.

Before installing a deck, you must build a base for the deck to rest upon, often made of compacted soil or gravel. While gravel is an optional material, it helps with drainage. Some contractors also recommend installing a weed control membrane, which helps provide a solid foundation for the frame. In the case of an elevated deck, a pro will often lay down a concrete slab as a foundation. 

Yes, adding a composite deck, such as one made from Trex, can significantly increase your home's value. It is a valuable home renovation for recouping costs, with some estimates for return on investment (ROI) ranging between 60% and 70%. More recently, Remodeling's 2024 Cost vs. Value Report suggests a deck addition has an ROI of 82.9%, with an average resale value of nearly $14,600. A new deck makes your yard more functional, enhances the landscape's aesthetic, and can entice prospective buyers. The investment may have a higher return if the deck adds usable square footage to the property.
