"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."

"My husband and I hired Plomariâ s crew to power wash, repair and stain our deck, stain the backyard fence and level our ceiling. The two-men team worked tirelessly over the course of four days and brought everything in perfect shape! Our deck looks brand new, the backyard fence is well preserved and the ceiling looks perfect! This is the second time weâ ve hired Plomari and weâ ll definitely work with them again. Super-tidy, hardworking and respectful workers and reasonable pricing for a solid service! Highly recommend them!"

"Did a fantastic job on a 33 year old two story house with over 30 windows and 4 skylights. No job is too big for Mr. Flores. His prices are excellent as is his service. Would highly recommend."

Customers say: Terrific value

"I hired them for deck repair. We had an older sagging deck. They came in and took off the top boards, installed additional support structure and reattached the deck to the side of the house. Their estimate was way less than competitors. They were courteous, on-time and communicative. I will hire them again if the need arises."

"We are very happy with our resurfaced deck and screened porch. It is exactly what we envisioned. Leonpros builders worked despite the freezing, snowy weather. They left the job clean and orderly every evening. The builders were always courteous and professional. We have a beautiful screened house on our deck. I have recommended Leonpro Services to family and neighbors. I would use them again."

"Guillermo, the owner of D&V Remodeling, has been absolutely fantastic to work with. I hired him to do few diverse projects and he was very knowledgeable, efficient and performed superb quality work. Itâ  s not every day that you meet a contractor that has your best interest in mind, is honest, trustworthy and just genuinely a nice person that wants to do his best for his customer and does it so well. I value attention to details and I was truly impressed with his work. Guillermo was very communicative in keeping me up to date on scheduling and then before the projects started, during and after. Overall, it was absolutely a pleasure to have him work on my projects. Even though I was not available to monitor every aspect of the projects, he delivered superbly high quality of work. I also appreciated his flexibility to get me on his schedule. I will DEFINITELY hire him again!"

"Edward and his team did a fantastic job staining our new hybrid deck and painting the front porch! They worked meticulously to tape around all the composite wood before staining the deck. It was a significant amount of work at a very reasonable price. Edward also returned to the house to touch up a few spots after the team was finished. Lastly, he was very flexible with the timing of the project, as we had to push the start date back a bit when something came up. Weâ d highly recommend D. Fuentes Painting for any painting or staining project!"

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