"Ryan at All Touch Power Wash was fantastic to work with. I had a quote right away and they could get me on the schedule within a few days. The price was very reasonable and they did a fantastic job. They power washed my entire PVC fence and it looks great. I highly recommend them."

"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."

FAQs for deck, fence, patio or porch clean and seal projects in Bel Air, 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.
