"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."

"Outstanding. The All Touch crew does an outstanding job with powerful pressure washers that reach even 40 and 50 feet tall. They use a potent chemical combination that not only removes the grime, but also ensures that it provides a protective barrier. This is the second time I've had them out, and will continue to have them out yearly as the quality of the work is amazing. HIGHLY RECOMMENDED."

"Great work and service by Eric, Ricardo and the crew. They went above and beyond with fixing the fireplace stone, power washing the patio, installing our grill, running the gas line from the house to the grill, and reporting the patio and stone wall. Highly recommend their service."

"All done well. Final seal on rhe deck took a while to get done (rain/wet surface delayed it). Phone contacts with road crews were the issue: did not alert us of a cancellation on a wet day they were to seal the deck, then showed up on a later date without warning or a doorbell ring when they did decide to do it. Good, hard, thorough workers, to be sure, and the office-staff phone contacts were all very responsive."

"Not only do we love our new roof, we loved the service and timeliness of the work. Jim came out the same day and gave us an estimate, and was able to replace our roof in one day. He and his team leave no stone unturned, are VERY clean, and spent extra time after our job was done making sure no nails or bits were left on our property. Very impressed!"

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.
