"Moser Construction did an excellent job building a deck for us. The crew was prompt, respectful, hardworking, and accommodating to a few new requests that we made. The deck looks great, and we're already enjoying it. I highly recommend Mike and his team!"

"I hired George Hunt to build a Trex deck last year. He was professional about estimates and issues with the build. I needed a dog ramp for my dachshund since the deck is over 5’ high . George worked with me to design a highly useful, yet attractive integral dog ramp to my backyard. His crew was courteous, helpful and worked very well together. The lumber needed for the deck was high quality, as was the decking material. I was impressed with the careful work they did and with the results. I love my new deck and have used it for most of the seasons. I love the views I have from the deck. My dog also enjoys the views and the cleverly constructed ramp. I am so glad I hired George to do the job."

"I am beyond thrilled with my new front porch. I am a very particular person and the entire crew kept me involved in the building process each step of the way. I was able to determine exactly how I wanted the porch to look down to the inch. No one made me feel as if I was difficult or hard to please. Instead, they confirmed to me over and over that their job was to make me happy."

FAQs for deck or porch projects in Carnegie, PA

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.
