"I was searching for someone to install drywall on one living room ceiling constructed with old split lathe and plaster (plaster already removed). I browsed Home Adviser for possibilities and ran across Dependable David. His outstanding reviews from numerous customers stood out among all others. Surprised by such a consistent, positive experience from individuals that he worked for, I decided to give him a try. After his work was completed, here's my thoughts: Prompt arrival. Methodical, plans ahead. Steady worker. Cleans up messes. Completes work without delay. Good quality. Kept within prior estimated price. I'm happy to join all the others here and give a 5 out of 5 to David!"

"Sean is an absolute pleasure to deal with. He is prompt in returning calls/emails. He is understandably busy because he does excellent work at a reasonable price, so call ahead. We first became acquainted with Sean when we were unexpectedly hosting a funeral reception for a large number of people. He was willing to accommodate our emergency time frame, power washed our home and decks perfectly and left our shrubs/plantings in perfect condition. Since then, he has washed that home a second time and today our new home which is larger and has odd peaks and gables with a large deck and privacy fence. Except that everything was perfectly clean, it was as if no had been there. We can highly recommend Sean, and will have him wash our home and deck annually going forward."

"We were very pleased with the job they did. The quoted price was considerably less than any other we received. They were pleasant and polite. We will definitely recommend and hire them again. We also used these folks to power wash our roof a couple of years ago and their price was way below anyone else. Good Job!"

FAQs for deck, fence, patio or porch clean and seal projects in Dover, NH

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.
