"John and Lou were very professional and did a great job on power washing, sanding, and staining my large deck. They went out of their way to make sure everything worked out. The deck looks amazing now, it's the best I've seen it look in many years. John had great recommendations to make based on his expertise such as the stain type and color to use as well using great methods to ensure the final product came out excellent. Would hire again and recommend their services to anyone."

"Sandro and his team did excellent work, professional and great customer service. He wanted us to be more than satisfied with the work. I was very happy with the results. I thought my deck was beyond repair with the dirt and mold but with a thorough cleaning, light resurfacing and stain of my choice it is as good new."

Deck Maintenance FAQs, answered by experts

Before installing any materials under the deck for removing moisture, you should perform some prep work on the ground. Work the dirt under the deck to create a grade away from the home. A grade of at least six inches for every 10 feet works well. Do not leave a gap between the dirt and the home’s foundation where water could pool. Once you or a contractor regrades the dirt under the deck, you then can add materials over the top.

It’s important to make sure the wood on a new deck is properly seasoned. Seasoning a deck is simple: Once you build it (or have a pro do so), just leave it alone so it can acclimate to the environment. If you don’t give the deck proper seasoning time before staining, the stain can lock in any lingering moisture and cause mold, rot, and other moisture issues down the road. Give the wood at least four to eight weeks to season before you stain.

Composite decking is the best material for individuals living with disabilities who want to age in place. The material is anti-slip, which increases safety throughout the year. It’s also highly durable and requires minimal maintenance, so it doesn’t add another item to the individual’s to-do list. It’s also a good option for improving wheelchair accessibility at home, as it can easily manage a wheelchair ramp.

Because adding a deck will yield a higher property value, you may have higher insurance costs. It’s important to follow the codes and regulations set by your local and state governments, so your insurance rates can be properly calculated. You may need an insurance revaluation after your deck is completed. The best course of action is to speak with an insurance professional to understand how adding a deck will impact your home’s insurance costs before you begin.

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.
