"Cornerstone did an excellent job with our deck which required a pressure wash and stain. At the start we requested a written quote and that was received within a day. Once the order was placed the administrative staff contacted me to coordinate the work which commenced within a very reasonable amount of time. This company is first rate, professional, prompt and courteous. The final project exceeded my expectation. I highly recommend Cornerstone Hydrowash and I most definitely will hire them again"

"Doug replaced a 30 year old deck support post and did an excellent job. He had to 'problem-solve' some prior construction issues which demonstrated his excellent carpentry skills. I will certainly use Doug in future projects around our home!"

"We are very happy with our resurfaced deck and screened porch. It is exactly what we envisioned. Leonpros builders worked despite the freezing, snowy weather. They left the job clean and orderly every evening. The builders were always courteous and professional. We have a beautiful screened house on our deck. I have recommended Leonpro Services to family and neighbors. I would use them again."

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