Deck Cleaning questions, answered by experts

No, you don’t need a permit to repair and replace a few boards on an existing deck. However, if you’re making structural changes to the deck or tearing down the old one and building a new one, you will likely need a permit. Check with your local municipality for the regulations and rules in your area, or ask a local contractor who builds decks for advice.

The best time to paint your deck is when temperatures are neither too cold (below 60 degrees) nor too hot (above 85 degrees). Always paint your deck when there’s no risk of rain. For fast-drying paint like acrylic or latex, ensure your deck can dry for at least four hours. Oil-based paints take longer to dry and may require 48 hours to completely cure.

Yes, Ipe is more expensive than Trex decking—both in terms of materials and installation (plus, Ipe trees are endangered). On average, Ipe decking costs $10 to $25 per square foot, while Trex decking costs $5 to $12 per square foot. Because Ipe is harder to work with, the price of installation is higher, too. For Ipe decking, you’ll pay between $20 and $45 per square foot for labor. However, with Trex decking, the labor costs range from $8 to $22 per square foot.

The best material for your deck depends on several factors, including your budget, location, aesthetic preferences, and the level of maintenance you’re willing to do. Wood decking, like redwood, ipe, cedar, and pine, lasts the longest, but it’s more expensive and requires more upkeep than composite and synthetic decking.

Most building codes list a minimum width of 36 inches and a maximum height of 7¾ inches. However, for the most comfort and spaciousness, you’ll want to aim for a width of at least 48 inches and a height of 7 inches. Again, it’s always a good idea to base your numbers off steps that you already use comfortably.
