"From the moment we contacted Deck Guardian for a quote until the time the final inspection was approved by our township, the entire team at Deck Guardian was nothing but professional, responsive and patient. Larry managed our quote. He helped guide us through the design and material selection. Replacing our deck was quite an investment and Larry was extremely patient with us as we debated every single decision. Our project manager Jon communicated with us at every stage of the build - confirming materials, coordinating deliveries, managing the construction schedule and working with the town on permits and inspections. The construction team was amazing. They always showed up as scheduled and were meticulous with the build. The construction of our new deck is top notch and not a single corner was cut. We absolutely love our new deck - it was worth every penny. We can't wait for the warm weather to arrive so we can fully enjoy it. Thank you Deck Guardian for making this process enjoyable, simple and stress free."

"Very happy with my experience with Joseph and Sons Construction. Was looking for a local contractor to handle several small/medium size projects around the home. Reviews were good so went with them. Could not be more pleased with the quality of work and responsiveness from Angelo. By the time it was finished, he felt like a neighbor Iâ ve known for years. He answered all my questions, and all work was completed exactly as described. The work included new brick and stone patio, foundation repair, porch repair, replacement of basement windows. Also gave many good suggestions for improvements I could do myself. I would definitely recommend them for any projects, big or small, around your home."

"I took a chance with CSZ construction because Home Advisor reviewers were so positive-- and I am glad I did. Cesar, the owner, is a very competent professional who did most of the work himself. He weatherproofed my balcony door, fixed a window and replaced the water line of my refrigerator. His prices are very competitive and he will be my go-to repairman from now on."

"The job went very well and looked better than I imagined. I had a traditional pressure treated deck that was built 25 years ago. Maintenance was a nightmare to the point I stained the deck a solid color. This needed to be freshened up every couple of years. I tired of doing this chore so I contacted several contractors. Those contacted were not very enthusiastic and submitted extremely high bids without explaining exactly what materials they were using or a plan of attack. Brian of Carls Decking came with samples, brochures and a no nonsense explanation of what needed to be done to put me” in my happy place.” Brian inspected the frame and found it to still be level and in good shape. He suggested a total rip off of the planks and replacement of steps deck boards and railings. He even obtained the railing permit and made sure final inspection was handled. Pricing to do this type of renovation is not cheap but the final result was worth every penny! The crew that Brian sent over did an amazing job! The premises was cleaned up everyday when they left and all work was done in a very professional manner. I recommend Carl’s Decking very highly."

Customers say: True professional

"We can not say enough wonderful things about Homeland Remodeling Group. To start, Dan answered our inquiry the day after we sent it and he showed up when promised. Many contractors would either not respond or promise an estimate and not show. Dan was on time and he provided us with the estimate before he left that same day. While waiting for the siding to arrive, Dan was very responsive, providing updates. Once the material arrived, the crew was very professional and worked efficiently. They would arrive at 8:00 am and leave at 5:00pm. The siding, fascia, soffit and gutters look perfect. Honestly, we could not have asked for anything more. Any request we had during the construction was addressed promptly. This company is very honest, reliable and attentive to detail. After the house was sided, the men cleaned up and our house looks better than we could have ever hoped for. We would definitely recommend this company and we will be using them again in the spring to work on an addition."

"We recently had a fantastic experience with Jim / OHI. They built us a beautiful new deck and installed a patio door, and the workmanship was excellent from start to finish. When we ran into unexpected building and zoning issues with the town, they were incredibly flexible and worked with us to adjust the project. Instead of the larger deck we originally planned, they created a stunning patio in that space, which turned out even better than we imagined. The crew was professional, reliable, and detail-oriented, and the results have transformed our backyard. We couldn’t be happier and highly recommend OHI to anyone considering a deck or patio project."

FAQs for deck or porch projects in Whippany, 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.
