"This company actually listened to what I wanted. We had a 40 year-old upper and lower outside deck that structurally was sound. If I were to replace these decks as suggested by several companies, my guess is it would have cost $35,000. This company assessed my decks from a structural standpoint and determined that they could rehab the deck with long lasting materials and my deck would be something I would be proud of. I am and they did the work in a week and a half at about one third of the cost of building a new deck. I highly recommend them."

"They first charged me an outrageous amount to figure out why my door was leaking and didn?t. They sent someone else to look at it. Who did figure out what was wrong . When they did come to fix the door, they did good work, but they charged me an outrageous amount of money to do it. They quoted me as having to rip up my whole deck to replace flashing. But when they came out to do it, they only had to pick up a couple boards .and redo the frame on a door and they charge me an astronomical amount of money. I am not happy. I will not be using them again. "

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