"They showed up in a timely fashion to provide me a quote.  After assessing his cost and the cost of another competitor, and pricing out renting a power washer for 4 hours, I decided to do the work myself.  I had a small enough house that I decided I could get it done and save myself some money.
If I had a bigger house or one that was significantly dirty, I would have utilized their services.

"Our deck looked to be in such disrepair we thought we needed a new one! Everet provided us a free consultation and ensured it was salvageable. In 2 visits our deck looked almost brand new! The price was very reasonable considering a new deck would cost thousands."

Deck Maintenance FAQs, answered by experts

Any wood deck provides some ventilation to the area below, as is the nature of that type of deck design. However, areas that experience excessive humidity and associated moisture benefit greatly from a dedicated ventilation system in the form of strip vents. This addition helps the various wood boards contract and expand evenly throughout the years and reduces the chances of twisting, warping, and buckling.

While experienced DIYers may take on the challenge, hiring a licensed professional is often the best route, especially for larger or elevated structures. A local deck contractor is typically the best pro for the job, as they have specialized experience and are knowledgeable about local building codes, ensuring your deck is built safely and designed to last. Other professionals who can build a deck include general contractors and carpenters, who may be more readily available in some regions.

Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.

Both aluminum and composite decking materials are environmentally friendly, with aluminum decking coming in as the most eco-friendly option. 

Though composite decking helps remove plastics from landfills, recycles wood, and lasts longer than traditional wood decks, it’s not recyclable and only lasts for 25 to 30 years on average. Aluminum can last well over 30 years and is almost always recyclable.

Rotting wood, loose railings, or unstable stairs may indicate a need for expertise.
