"Fantastic! The look of my patio is a 1000 times better! They cleaned it, refilled all of the joints with sand between the pavers, and put this sealer on that makes the patio absolutely gorgeous."

"I usually have my landscaper, brother or some other random person power wash my deck, rails and pavers. I decided to step it up a notch by hiring a professional. Mel was AWESOME. Contact was swift, bid was fair, scheduling was easy. Most importantly, I cannot believe how much better he did than an “average” person with a power washer. Everything looks brand new. Honestly, I’m shocked. I own several homes and I’m very picky about my contractors. I recommend MEL whole-heartedly. Plus, I love hiring an independent contractor. Good for him for making a business successful. Don’t look any further; Mel is your guy."

"Ricardo, the owner of the company, and his employees are amazing!! The deck looks incredible! Oscar, the main employee who built the deck was a very considerate gentleman whose work was impeccable. Initially we were not planning to have the stone patio laid this year. However, the deck work was so good that we decided to have G-Pro Landscaping install the stone patio this year. Once again, as with the deck, we couldn’t be more pleased with the craftsmanship!!! Ricardo has a true flare for architectural design and color choices. We have recommended G-Pro Landscaping to our neighbors and family. We will definitely hire them for our future landscaping projects!!"

"I was very pleased with how clean the siding looked afterwards. We had green stuff growing on the north side and all of it is gone now. The porch area was another area that needed attention. After the cleaning, it looked 100% better!"

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