"The contractor did a great job. He and his crew were respectful and efficient. The only problem that I had was with the bidding process. I accepted his bid of $1,500, but when he arrived, the contract that he wanted me to sign was for $2,000. I did not have a problem with the $2,000 price. That was what I fe;t that job should have been priced from the beginning. My problem was with proces. I like him and wished he had been upfront."

"Excellent service. I had a deck built. I would give FAMB a 10 if the chart would go that high. Mr Noel is a honest , hard working , Christian person. He completed the project like he said he would and did an excellent job. I will hire him again and recommend him to others."

"We were looking into redoing our old deck and got a quote which we thought was reasonable for our large deck. Then for another estimate, we called 7th State Builders. They explained that for the same cost, we could get a paver stone patio (which in the long run is far less maintenance). The owner worked with our budget and the gentlemen who laid our pavers were extremely professional and worked within our wishes. They removed the deck and finished the patio in about a week. Awesome job! After a week or so, it had rain for a period of time and we noticed that a small dip in the patio was collecting a puddle. After a call, they came out and fixed the problem. We would definitely recommend this company for a patio."

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