Should I clean my deck before sealing it?

Y ou 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.

Is it better to seal or stain a deck?

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.

How much does it cost to power wash and seal a deck?

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.

How often do decks need to be sealed?

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.

Can I leave my deck untreated?

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.

How long does it take for the sealant to dry, and when is it safe to use the deck?

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.

"The experience we had collaborating with Jeremy and the Sensible Home Products (SHP) team was outstanding and one beyond anything we could have imagined. In fact, we have never had a better experience with any contractor or company, of any type, than what we had with SHP. Trust, transparency, and talent are three essential elements that drive a fantastic customer experience. Jeremy demonstrated a level of trust that gave us comfort that the needed improvements made to our 90-year-old home, were appropriate and that the house would be safe, secure, and visually pleasing for future generations. This trust emerged from the initial quote that described the specific steps SHP would follow, to leaving the work area, every day, as spotless as when the team showed up, to traveling to the Boston area for a door that was not available at a store in Connecticut, to creatively and thoughtfully solving the issues and challenges the house threw at SHP, to taking every requested addition to the project with a can do attitude. In a nutshell, the SHP focus was ensuring that the improvements to our house would stand the test of time, and that the work was completed with care and dedication as if we were part of Jeremy’s family. Jeremy was transparent about the daily work. He sent us pictures of the progress made and of the structural issues that were uncovered. Although we would have wished wood rot, roof leakage, water damage and termite damage did not exist, they did. Because Jeremy provided the daily updates, he was able to share why the improvements were needed and important. He always answered my questions clearly and concisely. The SHP billing approach was clear so there were never any surprises. In fact, I was pleasantly surprised at how reasonably the project ended up costing. Observing Jeremy and the SHP teamwork was amazing. I have never seen such a talented, dedicated, caring, and creating team. They worked with amazing efficiency and effectiveness. I can attest, based on other projects we have taken on, this project would have taken much longer than the five short weeks (including Christmas and below freezing temperatures) this took. The quality of their work was remarkable and the pride in their workmanship was always evident. The extra touches he included in the project and the counsel he provided gave us 100% confidence that he would do what was right and that he, and SHP, would go above and beyond. The house is beautiful, and Jeremy and SHP will always hold a place in our hearts. They are an absolute gift, and they are now considered part of our family. I did not know Jeremy before this project, but I now count him as a friend. Going forward, we will call Jeremy and SHP first and we will know that he will care for us and for our house as if it was his own."
