"In a previous review I stated I had not heard anything from the company about necessary repairs. That WAS NOT an issue with the company or its owner! It was an issue with electronic communications failure on my equipment. That issue is resolved (I hope!) I would highly recommend this company to anyone needing any type of repair for their home."

Deck Maintenance questions, answered by experts

Liquid rubber is great for waterproofing, but it can damage your deck if it’s not applied correctly. First, it can trap moisture in the wood if the deck isn’t completely dry before application.  Second, applying it too thickly can create a heavy, rubbery surface layer that peels and cracks under fluctuating temperatures. For the best results, ensure the wood is completely dry before application, and apply the liquid rubber in thin, even coats. A quick inspection every now and then will help you catch any issues early, keeping your deck protected and looking its best.

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.

No, termites do not eat Trex or any other composite decking brand. Termites eat cellulose, of which composite decking like Trex contains very little compared to natural wood. This feature can help justify the higher Trex decking costs if you live in an area with abundant termites.

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. 

Decks are generally more expensive to build because they require elevating and railings. The difference between decks and patios is that decks are elevated, while patios are usually on the ground level. Plus, decks are usually made of wood and need more maintenance than most patios. However, decks and patios serve the same purpose, providing outdoor space for you to enjoy.
