"Matt arrived on time and was efficient at replacing floor tiles. Do you think customer service is gone, well so did we until Matt Hemingway came to replace three broken tiles. He finished in 90 minutes and that included going back to hardware store for a different color grout because he didn't like the way it looked. When done you could not tell the floor had been fixed. Excellent job. Highly recommend."

"I hired Custom Exteriors for a deck repair and new rails. They provided a free estimate and were able to perform the repairs within 2 weeks. The new deck looks great and the team was done in less than a day. Would recommend!"

Deck Maintenance questions, answered by experts

Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

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.

A deck doesn’t have to be perfectly level. Many pros even recommend a gentle slope to ensure proper drainage and increase longevity. The ideal gentle slope is about 1/8 to 1/4 inch per foot away from the property, leading water away from the home to prevent pooling and reduce the risk of damage. It also minimizes rot, mold, and other moisture-related problems. 

Yes, it’s definitely possible to build a pergola on an existing deck. All you need to do is attach the pergola support beams to the deck’s joists and build up from there. Beware that mistakes can damage your deck, so if you’re at all unsure of the process, play it safe and hire a pro for your custom build.

Hangers are one way of attaching stair stringers to a deck. These metal hangers are usually adjustable, allowing you to find the ideal angle for a secure installation. They’re the best choice for installing longer staircases, such as one on a two-story deck, to reduce the load on the deck frame while keeping the stairs stable.
