"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.

Deck Cleaning FAQs, answered by experts

Cold temperatures can make your deck boards contract. If they don’t contract evenly, they can put pressure on the deck screws and cause them to pop out, making a noticeable sound. Winterizing your deck can help prevent this from happening.

Constant exposure to inclement weather conditions can damage your deck, causing it to fade, warp, or crack over time. Regular maintenance keeps it looking and performing its best. That means giving it a good cleaning and applying a quality sealant or wood treatment to help defend against moisture, sun damage, and everyday wear.

It depends on the type of wood. The average cost to build a deck out of pressure-treated lumber is $15 to $25 per square foot, but more affordable varieties such as bamboo and cedar cost less at around $3 to $10 per square foot. However, when comparing the cost of vinyl decking versus wood decking, it’s important to also consider ongoing maintenance costs. For example, most woods require regular sealing to keep them protected against weather and rot.

If you have wood decking, there are several common deck problems that you might encounter. For example, your natural wood boards may fade over time due to things like sunlight, weather, and debris. On top of that, some types of wood decking can rot, grow mold, and attract destructive pests—including termites, carpenter ants, and woodpeckers.

When installing deck boards, screws are generally a better option than nails. Screws offer superior holding strength over time, keeping the boards securely in place. In contrast, nails are more likely to pop out, which can create a tripping hazard. While you can use either, we recommend using 3-inch galvanized deck screws. To minimize the risk of cracking the wood, it's a good practice to drill small pilot holes before driving the screws into the deck joists.
