"The front of my house was a green mess, Keith and Mary made my ten yr old gray siding & roof looked new. Made my 40 yr old garage roof look like a roof again. Very hard working and courteous on an extremely hot & humid day. Also cleaned my "green" fence back to white w/o me asking. Highly recommend & will use them again. Thanks for a hassle free job!"

"Moises and his crew repaired water rotted wood in difficult locations and completely finished the garage to every detail from insulation to molding, as shown in pictures here. They thought of every detail that shows their pride over their work. Not only is their work top notch, but they are also easy to work with and very communicative through the whole process. I have already hired them for a second job."

"John was at my house 15 minutes before he said he would be there, which was perfect. I’d rather have somebody early than late. He took his time and did the job just the way I wanted it done. He was neat and clean and left my place just as nice as it was when he came in he was respectful, efficient, and personable. It was a pleasure and I’m very happy that I hired him. He was also very reasonable. I’d recommend him to anybody who needs a small job or I’m guessing he could probably do a larger job as well, but my job was small so he was just the man for the job."

Deck Cleaning FAQs, answered by experts

To maximize the utility of space under a deck, it’s important to keep this area dry and clean. One way to prevent the area from becoming too wet is to install an under-deck draining system. This affordable home upgrade channels water away from the deck and provides usable space for storage or a functional area below a second-story deck. Not only will this be a useful maintenance upgrade, it can boost your home’s property value.

Constant exposure to inclement weather conditions can damage your deck, causing it to fade, warp, or crack over time. Regular maintenance keeps it looking and performing its best. That means giving it a good cleaning and applying a quality sealant or wood treatment to help defend against moisture, sun damage, and everyday wear.

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.

Your deck may look or feel fuzzy after pressure washing because the high-pressure spray tears some wood fibers as it removes the outer layer of dead and discolored wood. This fuzzy effect is a normal part of the pressure-washing process and will go away on its own in a few weeks. You can opt to spot-sand your deck if you’d like to remove it more quickly.

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.
