"R & L was great - very responsive, professional and reasonably priced. I thought our deck and fence needed replacement and that the house trim needed painting. But really, they just needed a good cleaning. Well worth the money and I'll hire them again to pressure wash my patios."

"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."

"I brought C& Painting in for a job that most painters shy away from?painting a vinyl fence and a concrete exterior wall. Both surfaces need special prep and materials, and I wanted it done right. From the first conversation, I could tell José and his crew knew exactly what they were doing. They walked me through the plan, handled every step with care, and delivered a finish that looks incredible. The fence looks brand new, and the concrete wall has completely transformed the look of my home. Skilled, reliable, and genuinely great to work with. They absolutely nailed this project."

"Highly recommend. CCE staff arrived to give quote for wood deck washing and offer accepted, very fair pricing and promise of outcome. Staff arrived to our house on time and went directly to work, very courteous, high degree of tasking skills, and performed as advertised. We were so very excited about the wonderful restored appearance and physical status of our, prior to this work grayed and dirty deck wood. The staff cleaned EVERY SINGLE SURFACE of the deck, looks like it was just installed. Yes, I will recommend and employ CCE for any future house repair needs."

Customers say: Terrific value

"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!"

"Mr. Jerome called, emailed, and texted promptly. He arrived on time to give me a quote for the repairs of my front sidewalk. We scheduled an install day for Friday, and he stopped by a day early to neatly cut out the bad sections. On Friday the team arrived a bit early and got right to work. They were done within a few hours, and I'm very satisfied with the result."

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.
