"Francisco is a great communicator, kept us informed about the job along the way. His men were clean, prompt, and did the job in the given time. They adhered to Covid recommendations. Their bid for the job was competitive and the quality of the work was excellent. I would highly recommend them and I would use them again if I needed more painting done."

"Very easy to work with. I'd used them before but this time I got estimates from other contractors and was amazed how much more reasonable Cal Preserving was. The difference may be that the others pointed to additional steps that could be taken. Did Cal Preserving "miss" these things or recognize they weren't necessary--I'm inclined to believe the latter."

"Fantastic job! I can't believe how bright and clean the deck and the surrounding areas look. It's clear that Blue Wave takes pride in their work and goes the extra step to please the customer. The windows have never looked better. Some are quite hard to reach and have not been cleaned in ages. They look brand new. I'm so happy with the expert and professional service provided by Indira and her team. I will definitely call Blue Wave again."

"DJS' crew worked fast and did a very comprehensive job. They arrived on time, were great about cleaning up after themselves and were pretty good communicating the state of the project. They were interrupted by several days of rain, but came right back and finished up when the weather cleared, putting in extra hours on a Saturday to finish the job in a timely manner. The house looks very sharp and clean, and the extra priming will help keep the older home protected from the weather. It took a great big chunk of our budget for repairs, but they definitely took care of everything, from color consultation at the beginning to clean up at the end. The speed and convenience of having professionals who clearly knew what they were doing was worth the price.

Deck Cleaning questions, answered by experts

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.

In most cases, there should be a small gap between the house and the deck, usually no more than ½ to ¾ of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the most common issues with decks.

The best way to clean your decking is to clear debris from the gaps between the boards, sweep the surface, rinse it, apply cleaner, rinse again, and let it dry fully. A homemade deck cleaner made of two gallons of warm water and 1/2 cup vinegar is a simple cleaning solution for both wood and composite decking. You can sprinkle baking soda on any spots with mold or mildew, then scrub the area and rinse clean. 

Two coats of stain are ideal for the best protection and aesthetic appeal. However, if your decking is made of particularly dense hardwood, you may only need one coat. If you want an intense color, two coats are ideal.

You can nail or screw composite decking, but 3-inch decking screws are the better fastener choice. Unlike nails, decking screws won’t back out of the composite material over time. There’s also little danger of splitting composite material when driving screws, so you don’t need to pre-drill holes unless otherwise recommended by your decking manufacturer.
