"Gary and his team did a great job replacing the long stairway and steps to my rooftop deck. Everything from the estimate through completion of the project was professionally handled. The end result looks great. Highly recommend them."

"Painters arrived exactly on time and accomplished all tasks the same day. The manually stripped the deck and applied two coats of stain. They carefully cleaned and then painted the foundation concrete as it had got dirty over the years. They also scraped, caulked and painted a large bump-out window off our living room.

"Darrren and Randy are the BEST!! They were prompt-clean and a pleasure to deal with. I came home at the end of the 2nd day--all the wallpaper was removed. The walls painted and they put all of the furniture back into place. The house was spotless and the only sign that anyone had been there was the smell of fresh paint."

Deck Cleaning 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.

Any wood deck provides some ventilation to the area below, as is the nature of that type of deck design. However, areas that experience excessive humidity and associated moisture benefit greatly from a dedicated ventilation system in the form of strip vents. This addition helps the various wood boards contract and expand evenly throughout the years and reduces the chances of twisting, warping, and buckling.

For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.

The proper and most comfortable height for a deck stair riser, also called a step, is between four and seven inches. A height of seven inches is often considered ideal for a strain-free step that minimizes the risk of trips and falls. While it is possible to have risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. For optimal safety and comfort, pair a seven-inch riser with a tread depth (or run) of at least 10 to 12 inches. Always check your local building codes, as they may have specific requirements that differ from these general recommendations.

There are approximately 5.33 board feet in a 2x4. You can use the board foot calculator in this article to easily find the answer. A 2x4 is 2 inches of thickness by 4 inches of width, so you need to find the length, with 8 feet being the most common. You’d use the calculator here to multiply 2 times 4 times 8, and then divide by 12, arriving at a total of 5.33 board feet.
