"James was amazing! He was in contact with us in scheduling a time to look at our project, we received an estimate by email the next day and let us know a time frame on when he could get the patio poured. He was extremely professional and the sub-contractor he hired to do our job was on-time and worked till late evening just to clean up the job site. I would definitely hire Driftless Craft for our next project!!!"

Deck Cleaning FAQs, answered by experts

To maximize the utility of space under a deck, it’s important to keep this area dry and clean. One way to prevent the area from becoming too wet is to install an under-deck draining system. This affordable home upgrade channels water away from the deck and provides usable space for storage or a functional area below a second-story deck. Not only will this be a useful maintenance upgrade, it can boost your home’s property value.

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. 

Liquid rubber is great for waterproofing, but it can damage your deck if it’s not applied correctly. First, it can trap moisture in the wood if the deck isn’t completely dry before application.  Second, applying it too thickly can create a heavy, rubbery surface layer that peels and cracks under fluctuating temperatures. For the best results, ensure the wood is completely dry before application, and apply the liquid rubber in thin, even coats. A quick inspection every now and then will help you catch any issues early, keeping your deck protected and looking its best.

The problems with composite decking include a high rate of expansion and contraction from temperature swings. This characteristic can cause boards to split, delaminate, or peel. In addition, significant movement can cause shrinking, warping, twisting, and bending. For this reason, you should minimize moisture and ensure proper airflow below your deck.

Yes, deck pier blocks can be used as an alternative to traditional deck footings, particularly for small or low-to-the-ground decks. Unlike poured concrete and buried post footings, deck blocks don’t require digging or pouring. However, their use is regulated by local building codes, and they may not be permitted in areas prone to high winds, earthquakes, or hurricanes. Always consult your local building codes before choosing them for your deck project.
