Massachusetts' Leading Wood Restoration and Maintenance Company. We restore weathered, grimy, moldy, splintered decks back to like new condition. Projects are usually completed within two days!

"We hired this company. I don't mind paying but when they missed so many areas. It's very frustrating and I have to finish the job myself. Anthony promised a great job and so didn't Nicole. I sure didn't even get a good job. The hand railings are super rough, and where the pressure washer chewed up the wood it was never fixed. It was definitely a hack job. I was promised over the phone a walk through at the end. It never happened. Couldn't communicate with the workers. I couldn't understand them. Definitely the pictures that they posted on other jobs don't match what I paid for. A very disappointing experience with this company. I would shop around.. plus I included Anthony in the last few emails and he couldn't even respond back. Awful !!! The handrails was addressed in after the power washing. The owner needs to go back and see the truth. I have the email saved!!!! Give me your email and I would be gladly to send it you!! You shouldn't be sparky when your team hacked my deck. I will be re-doing myself. Such a joke of a company."

Deck, fence, patio or porch clean and seals FAQs

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.
