"This company actually listened to what I wanted. We had a 40 year-old upper and lower outside deck that structurally was sound. If I were to replace these decks as suggested by several companies, my guess is it would have cost $35,000. This company assessed my decks from a structural standpoint and determined that they could rehab the deck with long lasting materials and my deck would be something I would be proud of. I am and they did the work in a week and a half at about one third of the cost of building a new deck. I highly recommend them."

"The owner of TrueDecks took the time to come to our house to discuss our vision for our new deck and screened-in porch, created plans that met our goals, and then ensured that the architect prepared detailed plans and drawings. The team at TrueDecks followed the lengthy permitting process through completion and prioritized our project, so that it would be completed in time for us to enjoy the warm weather. Pavel and his team were truly excellent, and were flexible in modifying plans to meet our needs. When the project was complete, TrueDecks gave us the option to clean the exterior of our home so that it would look great with our new deck and porch. I appreciate the TrueDecks team and their dedication to customer service. Pavel managed our project and was truly exceptional."

"Vtile did an amazing job replacing the brackets on my deck that were rusty and old. It was a small project but important to me that my deck remained safe for me and my guests. The price was reasonable, they showed up on time, did an excellent job and left the work area spotless! Iâ m a very happy customer!"

"After deciding to rebuild our older deck, we had to do some research on companies and speak with prospective vendors. We met with four businesses and carefully evaluated their offerings, services, quality of previous work, and costs. We ultimately chose the Deck Buddy primarily because of their professionalism, approach, and openness during the selection process. Doru was the primary point of contact throughout the entire process, and we chose to work with them because of his dedication, approach, and responsiveness. Every day, his team was punctual, courteous, and clean. They began on schedule and completed the entire project ahead of schedule. We are pleased with our deck and highly recommend his business and staff. Excellent work."

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