"My husband and I are so happy with our new deck. Just in time for the beautiful weather! We have Jose Diaz with Alta renovations corp. to thank for making our home improvement job stress free. He and his crew were extremely prompt, meticulous, courteous and great communicators. Jose made me feel comfortable asking questions and was prompt to respond. It was truly an absolute pleasure working with them from the start to the finish !"

"Niko and his team did an excellent replacing my cedar deck with Trex deck. The deck boards were rotten and their removal revealed other rotten wood on the outside of the house. Niko and his team were able to design a beautiful deck and also take care of any other decking/siding issues that came up. Highly recommend!"

"How refreshing to find professionals that were willing to work with us and offer suggestions for our project and go above and beyond in their work. They were attentive to the smallest detail and helped to restore a great screened-in porch for our family. The work was completed in the designated time frame and all clean up was respectful of our shubbery and furniture. We would recommend this company and their owner for any future projects. Great to work with people who continue to hone their craft."

FAQs for deck or porch projects in Greenport, NY

Northern white cedar is the most affordable cedar decking type and delivers exceptional value with low material expenditures. This option provides proven cost efficiency, meets essential durability standards, and is easy to paint or stain to meet your aesthetic preferences. By comparison, eastern red and western red cedar supply extra longevity and richer texture for a modest increase in investment.

Yes, cedar is a great choice for decking material. It offers a timeless look and natural resistance to decay and insect damage. Keep in mind that cedar requires regular maintenance, like resealing and cleaning, to keep it in top shape. With proper care, a cedar deck can enhance the appeal and value of your outdoor space for years to come.

No, cedar is not pressure-treated because it contains oils and tannins that naturally resist insect damage, rot, and decay. With regular maintenance, including annual cleaning and resealing every two to three years, cedar maintains its structural integrity and pleasing appearance for 10 to 15 years or more. Cedar’s natural durability, without need for chemical treatments, makes it an environmentally friendly option for outdoor structures like decks.

You should stain or seal your cedar deck every two to three years to maintain its appearance and longevity. This helps protect the wood from moisture, mold, and environmental damage, preserving its natural color and extending its lifespan. Regular maintenance keeps your outdoor space both attractive and durable season after season.
