Top Deck Cleaning Mistakes Lafayette Homeowners Should Avoid

May 27, 20257 min read

Decks are a beautiful addition to any Lafayette home, offering the perfect outdoor space for relaxation, entertaining, and enjoying the natural beauty of Louisiana. However, maintaining your deck can be a challenge, especially when it comes to keeping it clean. 

Lafayette's hot, humid climate, combined with seasonal rains, can quickly take a toll on your deck. Over time, dirt, mold, mildew, and algae can accumulate, leaving your deck looking worn and unsightly.

But don’t worry—deck cleaning doesn’t have to be complicated. The key to keeping your deck in great shape is understanding common mistakes homeowners make and learning how to avoid them. In this post, we’ll walk you through the top deck cleaning mistakes Lafayette homeowners should avoid, and provide practical tips for keeping your deck looking pristine year-round.

1. Ignoring the Local Climate’s Impact on Your Deck

Lafayette’s climate plays a significant role in the wear and tear of outdoor surfaces like decks. With Louisiana’s frequent rainfall, humidity, and occasional extreme heat, your deck is exposed to a variety of elements that can damage its surface. Mold, mildew, and algae thrive in the warm, damp environment, especially in the spring and summer months.

What many homeowners fail to realize is that the materials of their deck are directly impacted by these weather patterns. Wood decks, for instance, are prone to rotting and warping if not regularly maintained. Composite decks may not rot, but they can still develop a layer of grime that detracts from their appearance.

To combat this, ensure that you're taking the climate into account when planning your deck cleaning routine. Instead of waiting until algae or mold becomes noticeable, regularly clean and inspect your deck for any signs of damage caused by weather conditions.

Tip: Be mindful of cleaning your deck more frequently during the wetter months of the year. This will help prevent build-up and damage from moisture.

2. Using the Wrong Cleaning Products

You’ve probably heard about using bleach or harsh chemicals to clean your deck. However, these products can actually cause more harm than good, particularly on wooden decks. Harsh chemicals can strip away the protective finish and cause the wood to dry out, which may lead to cracking and splintering.

In addition, bleach is not effective in removing mold or mildew in the long term. While it may bleach out visible spots, it doesn’t address the root of the problem. The spores will still be present and may return sooner than you'd like.

When cleaning your deck, always opt for products designed specifically for deck surfaces. These products are gentler on the material and formulated to address common issues like mold and mildew without causing damage.

Tip: Stick to environmentally friendly, non-toxic cleaners that are safe for both your deck and the surrounding landscaping.

3. Using Too Much Water Pressure

Pressure washing can seem like a fast and effective way to clean your deck, but using too much water pressure can do more harm than good. High-pressure water can strip away the protective coating on your deck, causing splinters in wood decks and damaging the surface of composite or vinyl decks.

If you decide to use a pressure washer, make sure to use it on the lowest setting and keep the nozzle at least 12 inches from the deck’s surface. It's also important to always work in the direction of the wood grain when pressure washing a wooden deck to prevent damage.

Tip: If you’re unsure about using a pressure washer, it’s always a good idea to call in a professional who knows how to clean your deck safely.

4. Not Cleaning and Sealing Your Deck Regularly

One of the biggest mistakes Lafayette homeowners make is neglecting regular cleaning and sealing of their deck. Wood decks especially need to be sealed every couple of years to protect them from moisture damage and UV rays. Failure to do this can result in fading, cracking, and warping over time.

When you don’t clean your deck regularly, dirt and grime build up, which can attract mold and mildew. The longer you wait, the harder it is to restore the deck to its original condition.

Tip: Set a reminder to clean and reseal your deck at least once a year. In Louisiana’s humid climate, sealing your deck will also help protect it from the elements.

5. Not Addressing Small Problems Quickly

Your deck may look fine at first glance, but small problems—like a little discoloration or some surface grime—can quickly turn into bigger issues if left unchecked. Ignoring minor mold, mildew, or algae growth can cause the problem to spread and worsen. Additionally, wood can begin to rot or splinter if not treated early.

If you notice a problem, address it right away to avoid expensive repairs down the line. Keeping up with maintenance is key to preventing small issues from becoming major problems.

Tip: Inspect your deck every few months to catch small issues before they become bigger headaches.

6. Failing to Consider the Type of Deck Material

Wooden decks are not the same as composite or vinyl decks, so they require different cleaning methods. Wooden decks, especially pressure-treated ones, need more maintenance to protect against moisture and the sun's UV rays. Composite decks, while low-maintenance, can still get dirty and need to be cleaned using specific methods to preserve their appearance.

Failing to consider the material of your deck is a huge mistake. Using the wrong products or techniques can damage the surface or leave it looking uneven. Always refer to the manufacturer's recommendations for the best cleaning practices based on your deck’s material.

Tip: Take the time to research your deck material and choose the appropriate cleaning products for the job.

7. Overlooking the Safety of Your Deck Area

While deck cleaning is important, safety should always come first. Ensure that the area surrounding your deck is free from obstacles and that the deck itself is structurally sound before beginning any cleaning. If you’re using a ladder or power washing equipment, make sure you have a firm grip and stable footing to avoid accidents.

Tip: Take a few extra moments to inspect your deck for loose boards or nails before cleaning. A quick inspection could save you from future repair costs and potential injuries.
