"I had a literal “garden” growing in my gutters. Nate explained everything he would do and the solution he uses. I also had a whole house cleaning. Including garage and deck. The results are amazing. He was prompt and efficient. Will use his services again and strongly recommend."

"Bart Costello applied two coats of high quality oil-based sealer. It filled in the cracks and I'm confident that it will protect my driveway better that previous applications. Bart was on time, cleaned-up after he finished and tied a plastic stripe across the driveway. I codlin''t have asked for a better job. He is efficient, knows what he is doing, and is polite to boot. Highly recommended."

Deck Cleaning FAQs, answered by experts

There are ways to clean your deck to help maintain a clean appearance. You can easily remove surface-level dirt and grime by wetting your deck with a hose and doing a quick scrub with store-bought deck cleaner monthly. 

However, investing in professional deck cleaning services near you at least twice a year is worth it. This service saves you time and ensures that your deck will avoid accidentally becoming scratched by blasting the pressure washer at the wrong angle.

The best material for your deck depends on several factors, including your budget, location, aesthetic preferences, and the level of maintenance you’re willing to do. Wood decking, like redwood, ipe, cedar, and pine, lasts the longest, but it’s more expensive and requires more upkeep than composite and synthetic decking.

It depends on the type of wood. The average cost to build a deck out of pressure-treated lumber is $15 to $25 per square foot, but more affordable varieties such as bamboo and cedar cost less at around $3 to $10 per square foot. However, when comparing the cost of vinyl decking versus wood decking, it’s important to also consider ongoing maintenance costs. For example, most woods require regular sealing to keep them protected against weather and rot.

It is recommended to clean your deck once or twice a year to prevent the accumulation of dirt, debris, mold, and mildew. The ideal times for cleaning are in the spring and fall. A spring cleaning removes grime that has built up over the winter, preparing your deck for summer use. A fall cleaning washes away messes from summer activities, preventing them from setting into the wood over the winter. The exact frequency can depend on factors such as how often the deck is used, its exposure to pollen, and whether salt was used on it during the winter. Regular cleaning helps protect the wood and its finish from damage.

A deck doesn’t have to be perfectly level. Many pros even recommend a gentle slope to ensure proper drainage and increase longevity. The ideal gentle slope is about 1/8 to 1/4 inch per foot away from the property, leading water away from the home to prevent pooling and reduce the risk of damage. It also minimizes rot, mold, and other moisture-related problems.
