"Johnston General Contracting did very fine work on power washing and sealing my deck. The deck looks great. While he was late on the first day of the job the second day he was right on time. I would recommend this company. The only negative would be that the price seemed on the expensive side."

"Brian's a good guy and always responds in a timely manner. Built a composite deck for me and looks good but his rates are high so I took a star off. Time will tell whether or not he was worth the additional $17 a square foot more than what home advisor said"

"Amazingly, they were a last minute decision to get ready for a gathering at my home. Within s few hours of they had my place ready to go. They even took care of replacing my deck lights. Have their number on speed dial now. That short turnaround and attention to detail made for a great event."

Tony and his crew were exceptional in the work they performed.  First day, a crew of 4 started cutting in around the ceilings and doors.  Two of the crew came behind and started putting the first coat on.  Tony's son, Colton, was an extremely hard worker.  He made sure that we were happy with the way things were going. 

At the end of the job, Tony gave us painters tape to indicate any problems or mistakes that needed to be fixed.  The last day, he did a walk-through correcting any and all problems. 

We are very happy with the work done by this company..

"Mike did an excellent job in repairing my 30+ year old deck by removing all deck boards, railings and stair stringers and installed all new PT lumber. In addition, he replaced all joist hangers. I am very pleased with how the deck turned out."

FAQs for deck, fence, patio or porch clean and seal projects in Gettysburg, PA

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.
