"I wish all categories of home improvement could have a company such as Pro Builder from Garfield. Our wooden deck was in dire need of help. It was not an easy task because the deck is approximately 20 feet above ground level from the garden area. Through the expertise, knowledge, and commitment from this company, the project was finished on schedule. Our new composite deck looks outstanding!"

"JM turned a beat up, large backyard deck into a gem. Easy to work with and can offer suggestions of different aspects of the project. They took great care with a wisteria we've had for years that has wrapped around a portion of the deck's railing. I would definitely hire this company again."

Deck Maintenance questions, answered by experts

Deck boards should be spaced no more than three-eighths of an inch apart. This is enough space to allow water and small debris to pass through without collecting on the surface, but not enough to create a tripping hazard. Certain materials, like pressure-treated wood, shrink over time, so they may need less space at installation.

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.

You should refinish your deck to maintain its appearance, durability, and longevity. Refinishing your deck protects the wood from foot traffic and the elements. It also helps extend its life span by keeping rot, mildew, and termites at bay. By maintaining your deck, you can avoid the cost of replacing your deck sooner. A refinished deck also looks great and restores some of its original beauty.

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.

The most likely causes of a deck leaning to one side are damaged deck posts, soil erosion, and inadequate deck footings. If you’re not sure about the exact cause, the best option is to call a contractor who can build a deck to inspect the damage and recommend the best way forward.
