"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."

"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."

"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."

"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."

"My husband and I started to put in a fenced in garbage can patio, and made a mess of it. Andreas quoted me a good price, did the job right, was willing to use materials I already had on hand, did the job within the time frame we discussed, and didn't try to upsell me. I would definitely use them again."

"Hired Oscar to complete several tasks we did not have the time to do. Oscar was very professional, thorough, and delivered good workmanship on each task. He provided painting, light installation, deck sealing and repair, and mail post install, Oscar was personable and flexible to changes we made to the proposal. I would recommend a tighter method of keeping track of the total price between the customer and the service provider. Overall, I was very happy with the results."

"MC Fence & Deck built my dream deck, and I’m obsessed! Hunter walked me through the design, and his ideas made it way better than my original plan. John and his crew handled everything. Build and add an aluminum fence around the yard. They were professional and on time, and the craftsmanship is top-notch. Now my whole backyard looks like a magazine spread. I highly recommend these guys for decks and fencing. They’re the best in the business!"

"Tony power washed and stained the deck and fences as required. He did the work over a 2 weekend period to adjust to changing spring weather conditions which weren't favorable for staining. Tony is a very reliable contractor and I would use his services again for future deck and fence painting."

"I am very pleased with the cleanup done by Chris. I had a mold problem on a screened porch and he was able to clean it right up. Then he returned another day and varnished it to ****** further mold growth. It looks fantastic. The deck was power washed as well, and it too looks great. Chris was professional, responsive, and kept me informed about when he would be able to perform the job. I would definitely call him again."

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