"It went really well. Luis and his team did a thorough job of my pretty large house, he did the deck, patio, walkway and a couple of extra requests (oops, didn’t think I’d need those).! He even threw in washing of deck chairs and storage box that were moldy from being outside! All in all, he was very reasonable for pricing, and my walkways and patio look bright and ready for summer!"

"We needed a new walkway (or patio) to connect our front porch to the garage (to replace the original quartz stone, board, & flagstone design), a new front porch (since the boards were rotting), and we needed the EverGrain Composite Decking of our back deck power-washed and stained. Deckmaster was the only contractor who could do all three jobs, and the finished product on all three was great, and they gave us a great price. They redid the stairs on the back deck and gave us an extra step on the front porch, both of which we really like. Deckmaster was patient while we got our homeowner's association to approve the design, and they were very responsive and reasonable every step of the way. I'd definitely hire them again and highly recommend."

"the worker used some chemical that killed off a number of our plants below the deck. Maybe he thought they were weeds, but he should have asked before doing this. The stain job was fine and we were pleased with the results."

"We were very pleased with the level of service and the quality of the work. We had duckboards replaced, the entire deck cleaned and sealed, and it looks brand new. They also sealed our steps and wall leading to our basement entrance. We rated five stars because of the quality of work, friendliness, and attention to detail."

"We hired Kris' Painting Service to paint our deck/screened porch with a colored sealant. At first we were happy with their responsiveness and thought their quote was a good deal. As the project went on we were less happy with their communication and by the end of the project their overall quality of work. The door to the screened area needed to be replaced and they said no problem. They left the old door in our yard. Not very professional. They also told us there were multiple color options for the type of sealant but never asked us what color we wanted. Just didn't seem ask communicative once they signed us on and we sent in the deposit. The last thing is the new door was painted on most of the surfaces but they didn't paint between the wood and the screen. I understand this would be difficult but that's why we hired professionals. If it cost more, tell us and we'll pay for it but don't leave a half painted door. They also didn't install hardware on the door which again just seems like something they should have included."

"I couldn't be more pleased with the deck repair that Jose and Melvin of JW Home Improvement performed for us. The attention to detail, beautiful joints, use of screws instead of nails, and the particular attention appearance and completeness. The site was left spotless. A special thanks for your dedication to working in such cold weather. Thanks."

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.
