"Deck Guardian (DG) removed my old 600+ square-foot two-level deck and in its place constructed a new one using a similar layout. DG hauled away the old materials. I am completely satisfied with my new deck, which surpassed my expectation. I would rehire them for similar work and highly recommend DG to others. My only change is that I would require notice from DG before DG placed materials or a dumpster in my driveway. I was trapped in my garage for a day until DG made a path for me. This was a minor annoyance. During the sales process, a salesperson made stylistic recommendations, such as light-colored floorboards outlined with a darker color, which I accepted. He provided a detailed contract with pricing. Before the start of construction, I settled on a payment schedule for the contract. DG handled the permit process with my township. To begin the work, DG prepared a new blueprint. The upper surfaces of the deck were Trex materials and metal railings supported by a lumber base. I expect that this more expensive choice of surface materials will be maintenance-free. During the work, I could call or send email to the project manager and talk with him immediately or receive a call-back the same day. The two men who built the deck were meticulous and perfectionists. They courteously answered all my questions during construction. DG completed the deck within the time frame set out in the contract. They cleaned up all materials after they finished with construction."

"We recently had our deck redone by SB General Construction. We are blown away by the final product, which exceeded our expectations. Sokol, the owner, was wonderful to work with. He provided daily updates, was on site daily, had great recommendations, and always responded promptly to our texts or calls. His entire team was professional, respectful, and hard working. He completed the entire job, which included replacing our wooden deck and stairs with trex, adding a roof over the deck which includes a fan, recessed lighting, heaters, and a tv, in 7 days. This was slightly ahead of schedule. Sokol and his team even worked on Saturday and Sunday. We would highly recommend them for any project and we have already hired them for another."

"The removal of the old deck and building of the new deck was done efficiently and professionally. They contacted me immediately if I had to ok something. The cleanup was phenomenal. In addition they were very nice people. I am using my new deck and I couldn't be happier. I vetted 4 professionals before I chose MECI Construction."

"I've hired Jim and his team for several projects in the past year, including the reconstruction of an outdoor porch; installing a bathroom fan and running its venting to the outside; fixing up rotten boards and checking the integrity of a second floor porch; and replacing the ceiling, flooring, a window, and areas of the walls in an area of my house that I’m hoping to eventually rent out as a separate unit. As the owner of a multifamily property, I appreciated that Jim has had personal experience himself in managing and owning properties, and therefore had expertise in knowing the types of repairs that would be important and necessary for an owner/landlord. In addition to the time and effort that Shorty, Juan, and the other members of Jim's team put into each project, Jim also recommended and connected me with other contractors, including an electrician whom I've now worked with several times; a gutter installation company; and a masonry contractor who ended up installing a front retaining wall for me. As a final note to Jim's professionalism, when there was a period of extreme cold over the winter that could've caused particular damage to pipes in the upper floors of my house because of their placement near the outside, Jim personally called me to remind me to plug in the heated wire coilings that he had installed around the water pipes on my third floor. The thought hadn't even occurred to me until Jim’s call, and I appreciated that he took the time, even outside of normal working hours, to communicate with me and make that recommendation, since I was able to avoid any kind of burst pipes or other issues. I highly recommend Jim, OHI, and his entire team (again, a shout out to both Juan and Shorty, who were always friendly, helpful, and left the house cleaned after each project). He’s an experienced and knowledgable contractor who can quickly assess problems and offer solutions, and I value and appreciate the work he’s done on my property."

"I had put this project off way too long because I was dreading dealing with more shady, sketchy contractors. Living in a house that's 84 years old, I've had more than my share of those! I was so pleasantly surprised and happy when I found Carl's! Everyone was very professional, courteous and punctual, and the workmanship was impeccable. Craig was the project manage and very easy to work with. He understood my concerns about being without handrails on the newly installed masonry stairs for even one day and arranged to have his crew start their part the day after the stairs were completed. He even stopped by a couple of times while the mason was working to see how it was going. Once his crew got started, they worked very fast and efficiently and left my property spotless when they were done. I could have gone cheaper but I wouldn't have had the great experience or the beautiful front porch I got from Carl's."

"The owner, Leon, really oversaw the job. He came by to check with his employees several times during the day every day. The work performed was real old fashioned European craftsmanship. The skirt on the deck is so nice and even has a door so we can use underneath the deck for storage. The guys always showed up early and went right to work and stayed until 5pm (even in drizzly days) so our deck was finished quickly. The workers also took everything off the old deck and put it back when finished! Our deck is absolutely gorgeous!"

FAQs for deck or porch projects in Mahwah, NJ

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.
