Get matched with top deck staining pros in Algona, IA

Many decking oils can help slow down algae growth, but they don't completely stop it. These oils work by sealing the wood, which reduces moisture and, therefore, algae growth. Some decking oils also help protect against UV damage, but they need to be reapplied according to the manufacturer’s instructions to ensure the decking stays protected.

A wood deck needs an annual cleaning, plus refinishing every two to three years, which involves sanding the deck and applying stain or sealer. If you have a painted deck, you’ll need to repaint it every 10 years. You should also fix and repair loose or broken deck boards, nails, and screws. Cleaning your deck regularly and applying sealant protects the wood from the elements, water damage, rot, mildew, and fading from the sun.

There are more pros than cons when staining a deck. Deck stain is more affordable than paint, it protects the wood and allows the natural textures to shine through, and it can revive the appearance of your home. However, deck stain also requires prep work (sometimes days or more), carries more upkeep than a painted deck, and can fade over time if not cared for. 

Various kinds of substances and deck preservatives act as protective coatings for wood to prevent rot, which is caused by water getting into the wood and creating cracks and splits. Stains, paints, and sealants are the three best options to protect your wood, but there are also oils, varnishes, and waxes available. You’ll need to reapply sealant at least once per year, and you should inspect your wood deck regularly to look for signs of damage or general wear and tear.
