"They started each day at 8:00 AM and worked until 5:00 or later. They were very polite and professional. The lead person George would explain what they would be doing each day and then perform the tasks. The deck looks like it is brand new and the redwood has the original color and grain. Note: the bill included 4 hours of setting the deck screws so they could sand. Otherwise they performed to the bid."

As items requiring changes to the scope appeared, they were accommodating and quick to provide an estimate and complete with the project schedule in mind. As for the craftsmanship, the attention to detail and effort made to make our deck a beautiful space was really appreciated. These guys are great to work with and hit it out of the park! Thanks!"

Deck Repair questions, answered by experts

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

Pressure-treated decking may be worth it if you want a natural, insect- and rot-resistant decking material that will last for decades with proper maintenance. As such, it’s a much better option than untreated pine. Alternative wood decking materials like cedar and redwood tend to be less durable and more expensive. Some homeowners prefer composite decking, which is a low-maintenance alternative to wood but is also more costly.

As with patios, there are many types of deck choices to choose from to add personalization to your home. Some common deck options include:

  • Attached decks are anchored to the home and include simple ground-level options or multi-level structures with stairways and separate landings. 

  • Detached island decks are not attached to the home; they’re a freestanding structure in the yard. 

  • Wraparound decks connect the back of the house with at least one other side and often are built with railings for safety. 

  • Multi-level decks connect your deck through varying levels of elevation, featuring landings that are attached to stairs.

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.

Deck stairs should have at least three stringers rather than two. The recommended minimum width for stairs is 36 inches, and the International Association of Certified Home Inspectors recommends at least three cut stringers to provide sufficient support on wood decking stairs of this width. Generally, stringers should be a maximum of 16 inches apart for wood decking and 12 inches apart for more flexible composite decking.
