"This was the first time we had our deck power washed and stained by Rob. It hasn't looked this good since it was built. He also replaced some broken lattice work and everything he did was in a very skillful manner. We've already asked Rob to do other jobs for us around the house. We highly recommend him."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

Deck Maintenance FAQs, answered by experts

In most cases, sanding an old deck before staining it is necessary to achieve a decent finish. If your old deck has a relatively new stain finish on it and you're only doing touch-ups, you can generally skip the sanding part. However, if your goal is to make the deck look and function better, sanding first is a must. 

Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.

Unless you’re using a 2-in-1 formula or painting over an existing coat of paint, it pays to apply a coat of primer ahead of your new paint. Decks see a lot of footfall and exposure to extreme and sudden temperature changes and moisture levels. The primer promotes better paint adhesion, moisture repellency, and a smoother finish, which means you’ll often need fewer coats of paint. 

You can use a few different tactics to prevent your deck gate from sagging. Aside from using strong, rot-resistant woods, introducing a diagonal element—such as a tension rod or solid piece of wood to act as a brace—across the gate will offer better support. You can also use rigid joists to prevent the gate from sagging.

Whether composite decking is better than wood depends on your priorities, especially regarding budget and maintenance. Composite decking offers superior longevity (30 to 50 years) and durability, and it is low-maintenance, requiring no sanding, staining, or sealing. In contrast, wood decks typically last 10 to 30 years and need refinishing every few years. While the upfront cost of composite is higher than wood, the reduced maintenance can lead to long-term savings. If a lower initial cost is the primary factor, wood is the more affordable choice.
