"I built the home Mr William Smith was contracted to replace the screening of the gazebo on my home’s deck and then power wash both the gazebo and deck. Do working with contractors is not new to me. After cleaning he was requested to apply a clear stain of my choice inside the gazebo and then a solid stain of my choice to both the deck surface and the gazebo’ outsides. I could not have been happier with a contractor ‘s service performance. Weather cooperating he masterfully completed everything in 3 days as estimated. The screening replacement was not straight forwarded. It not just that Mr Smith and his support did a great job he did not require deposit or payment on this scale of job until it was completed and performance approved by me. He is as open and honest of a contractor as I have met. His attention to detail was as if it was his own property. Also his cleanup was excellent. I thought his price was fair and have already recommended his services to neighbors."

"Everything went great. The north side of my house had quite a bit of algae growth on the siding and Ryan and his coworker did a great job in getting rid of the algae as well as cleaning the siding on the entire house. What a difference. I hadn't realized how dirty the siding actually was. Everyone was professional and courteous. I would definitely hire them again. A GREAT JOB!"

"The roof is clean and looks good.  They also cleaned part of the chimney.   I am not sure they used a catchment system at downspouts as advertised.  The chemicals used smelled like chlorine.  The workers were friendly, but there was some confusion about the agreed upon estimate since it was not for entire roof.

Deck Cleaning FAQs, answered by experts

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.

Rot loves moisture, so deck rot typically impacts the parts of a board that stay wet. This includes the underside of boards, in addition to support posts and joists. However, any part of a board can rot, given the right conditions. 

Building a deck without a permit could lead to fines for both the homeowner and the contractor. The exact penalties will depend on your state and municipal building laws. You might also be required to remove the deck and apply for a permit before you can build another. While it might be tempting to skip the permit to save a few bucks, it’ll cost you much more if you’re caught.

A deck that isn’t attached to a house is called a floating or freestanding deck. These standalone decks are built near ground level, so they usually don’t need deck stairs. Some don’t even require permits. Generally speaking, building a floating deck is faster and more DIY-friendly than constructing one that’s connected to your home.

It’s important to make sure the wood on a new deck is properly seasoned. Seasoning a deck is simple: Once you build it (or have a pro do so), just leave it alone so it can acclimate to the environment. If you don’t give the deck proper seasoning time before staining, the stain can lock in any lingering moisture and cause mold, rot, and other moisture issues down the road. Give the wood at least four to eight weeks to season before you stain.
