"Awesome! Hire these folks!! They were wonderful. Careful and reasonably priced. I used them once in the past when I was at work and didn't see how careful they were. When I used them again this year I was home and watched how they moved my patio furniture and cleaned it when pressure washing the patio (even though I had not asked them to do so). Everything looked great, nothing got broken on my house from the pressure washing, and everything was cleaned up afterward. No stuff from the gutters left in my garden. They were also friendly and entertained my little ones."

"I wish everyone did business like these guys. The whole process was 100% online, from requesting the quote to paying for the service. They even did the house wash when I wasn’t home, so no need to take off work or schedule a time “window”. I’ve previously hired these guys to pressure wash my driveway and they did an excellent job on that, too. Definitely recommend and I will be a repeat customer for sure."

"I used this company for a number of years and the overall service is no longer the same. I had them over to clean my gutters and I witnessed ladders slamming against the side of my house and they tore one of the edges from the corner of my roof with their step ladder. I will not use them going forward."

FAQs for deck, fence, patio or porch clean and seal projects in White Marsh, MD

You should clean your deck before sealing it. Cleaning before refinishing is critical. If you don’t remove dirt and debris, you'll trap moisture in the wood, which prevents the new sealer from working correctly and can lead to costly repairs. Whether you need to sand, power wash, or sandblast depends on your deck's condition.

Sealing and staining your deck are essential maintenance methods that protect and beautify your outdoor space. Stain adds rich color and guards against fading, while sealant fortifies the wood against moisture and weather damage. Wood type, climate, deck age, and the degree of existing damage determine whether your deck benefits from one or both treatments. Using both options extends your deck’s durability and enhances its overall appearance.

Power washing and sealing your deck costs $500 to $1,700. This process combines the removal of stubborn dirt and debris with a protective seal that preserves the wood’s integrity. Effective cleaning eliminates harmful buildup, and a proper seal prevents moisture damage and wood decay, ensuring long-term durability and reducing future repair expenses.

Your deck must be sealed every one to three years to maintain its strength and appearance. Regular sealing is essential to protect the wood against moisture, mold, and harmful UV rays. A consistent sealing schedule prevents rapid deterioration and costly repairs. Inspections should be performed annually to determine if the protective layer remains intact, extending the life of your deck.

Leaving your deck untreated compromises its structural integrity and safety. An unprotected deck rots quickly due to moisture and environmental exposure, which means that neglecting sealing results in rapid decay and expensive replacement costs of $4,125 to $11,650. Sealing your deck is essential for maintaining its durability and protecting your home.

The sealant on your deck dries within a few hours and reaches full cure within 72 hours before regular use. It is essential to wait until the complete curing period to ensure the protective layer fully sets and resists weather and foot traffic. Proper drying guarantees that your deck is fully protected against moisture and environmental damage, ensuring lasting quality.
