"We were 100% satisfied with Washingtonian and with their work building our addition and deck. Not only was the workmanship and quality of the construction outstanding, but they operated with honesty and integrity. Their goal was our satisfaction and building a quality addition and deck. They accomplished all three and were reliable, dependable and conscientious. At no time did we believe that they had over-committed or were unable to deliver on what they had promised. They never cut corners to rush to another job nor did I ever feel that they were not spending the necessary time to ensure that the work on our job was thorough and complete. Travis, Kris and their crew were 100% professional, communicative and transparent. We will be using Washingtonian again, without hesitation. Our experience was excellent and they did an awesome job."

We design and build custom outdoor living spaces in natural wood, low maintenance materials, natural stone, and concrete pavers. We're fully licensed and insured. We have been in business since 1989 and have thousands of satisfied customers throughout the DC Metro Area. We are A+ Rated with the BBB and have won Angie's List Super Service Award for 6 years in a row. We do not offer staining, sealing, and cleaning services.

"I'm absolutely thrilled with the work Sean and his crew did on our screened porch. I'm fairly particular and wanted to be involved in the project, probably more than most clients, and Sean worked with me throughout to get the porch I wanted. He was communicative and explained pros/cons of all the various options. Partway through the project, we realized our pre-existing front porch needed some repairs too, and Sean seamlessly added that to the project and was very reasonable on the price. Once the team started, the work went quickly but was clearly done very carefully. The attention to detail was fantastic, and the end result is a beautiful and functional porch that we're thrilled with. In the first week after the porch was completed, at least 6-8 different sets of neighbors stopped us to say it looked great. I would absolutely use American Deck again for a similar project and have recommended them to friends."

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