Deck Maintenance FAQs, answered by experts

The best material for your deck depends on several factors, including your budget, location, aesthetic preferences, and the level of maintenance you’re willing to do. Wood decking, like redwood, ipe, cedar, and pine, lasts the longest, but it’s more expensive and requires more upkeep than composite and synthetic decking.

The best and fastest way to remove paint from a deck often involves combining a chemical stripper with a pressure washer. Gel-based paint strippers are highly recommended because their thick consistency makes them less messy and easier to apply than liquid strippers. After applying the stripper to loosen the paint, you can use a pressure washer to efficiently wash away the residue. When using a pressure washer for this task, it's important to use a low pressure (under 1000 PSI) to avoid forcing too much moisture into the wood, which could lead to mildew or rot.

A wood deck requires annual cleaning and regular inspections for loose or broken boards, nails, and screws. It should be refinished by applying a stain or sealer every two to three years to protect the wood from water damage, rot, mildew, and sun fading. The exact frequency can depend on the climate and the deck's exposure to sun and moisture. If your deck is painted, it will need repainting approximately every 10 years. Signs that your deck needs refinishing include faded, splintering, or warping boards.

If you want to make a deck cleaner from products already in your home, there are various options. The most common is to use a gentle blend of 1 gallon of warm water and 2 tablespoons of ammonia-free dish soap. You can also mix water with distilled vinegar. Sprinkling on some baking soda can help to remove mold and mildew. You can add oxygen bleach (but never damaging chlorine bleach) to the water and ammonia-free dish soap solution for something a bit stronger. 

Ultimately, overapplication of stain can compromise the deck's appearance, durability, and longevity. It may result in an uneven finish, with excess stain pooling, dripping, or drying into thick patches. It can also obscure the wood's natural grain and texture, detracting from the desired aesthetic. Moreover, excessive staining may not fully penetrate the wood, leading to poor adhesion and premature wear. Additionally, thick layers of stain are prone to peeling, cracking, and blistering as they struggle to bond with the surface.
