Why You Should Waterproof Your Deck in L.A.

From January to February of this year alone, Los Angeles has gotten more than 12 inches of rainfall. This isn’t too unusual. Deserts are mostly dry, but when it rains, it pours. Los Angeles infrastructure is often unprepared for this sort of liquid onslaught, which is why storms can cause such a significant amount of property damage. Here are a few reasons you should consider waterproofing your deck as soon as you can.

Leaks to Living Areas

If your deck is just above a living area, such as a kitchen or living room, any water that leaks through the deck will seep through the insulation and begin pooling in your ceiling, creating large circles of brown stain. Eventually, that leak will penetrate the ceiling and start falling on you, your furniture, and into your food.

Water in the Ceiling Causes Issues

Apart from creating problems in your deck, if the water manages to get into your ceiling, it could rot the wood or cause the ceiling plaster to bubble and expand. It will also damage the paint and plaster on nearby walls. Not only does this look terrible, but it will decrease the value of your home if you don’t get it repaired. Additionally, water in the ceiling and walls can cause mold and mildew growth. This fungus can also penetrate other areas of the home through the HVAC system and the vents, where it can spread to carpets, furniture, and clothing. People with allergies are more sensitive to mold than others, but if your home develops toxic black mold ( Stachybotrys chartarum ), it could be more problematic.


If you don’t waterproof your deck, it could lead to ponding, or the collection of pools of water on your deck. These structures aren’t meant to hold water, and standing water can saturate the wood beneath. Even with a waterproofing membrane, standing water can eventually erode through the substance. Installing a drain in your deck can help remove this problem after every rain.


Cracks in your deck can cause water to penetrate deep into the wood, potentially causing warps, rot, or mold growth. Warped wood can also cause tripping hazards if the level quality of the deck begins to be altered by uneven boards. Cracks can also become larger over time as the wood continues to warp with every rain. Part of waterproofing your deck is ensuring all cracks are sealed.

Even in Los Angeles, waterproofing is essential. The desert isn’t completely bare of moisture, so even morning dew can cause problems.

Why You Should Waterproof Your Pool Deck

In Los Angeles alone, there are more than 43,000 swimming pools, which means there are more than 43,000 swimming-pool decks . Many pools have concrete decks, which inevitably crack. Other pools, such as rooftop pool decks, are built over wood. Water can be relentless and destructive. If it can get into the smallest space within your deck, eventually you will have a bigger space. One of the reasons it’s so important to waterproof your pool deck is that consistent pool use will always get water everywhere.

Concrete is very porous, which is why waterproofing a pool area is vital. Not only will pool use expose the concrete to water, but it will also protect the surface from chlorides and other harmful pool chemicals. If you have children, some waterproofing products can even improve traction, which can protect you and your kids from slips and falls.

Wood decks are also particularly vulnerable to water. Not only is wood porous, but it tends to be softer, allowing water to erode it more quickly. Wood is also a natural material, meaning that once it’s wet, it is more likely to attract mold and mildew, which will quickly rot the wood. Wood also warps more visibly, which could make walking on it more dangerous and aesthetically displeasing.

Whether you have a wood or a concrete deck, waterproofing will preserve your pool area longer and keep it looking new for years. It will also save you money on later deck repairs.
