"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."

"After painstaking research and false starts, I found Construction Systems and glad I did! The crew was professional - defined as on time, detail oriented, efficient, thorough, patient in addressing my concerns, and top notch work. They ensured the gable work was excellent before calling it done. Joe’s estimate work was good and reasonably priced. Peace of mind knowing the job was priced well, done right, on time, and site cleaned up are invaluable."

FAQs for deck, fence, patio or porch clean and seal projects in Dulles, VA

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.
