"O'Rourke Deck Services recently completed work on our deck and patio. We were very pleased with both the process and the results. They were timely and professional, and communication was good throughout the process. Their work on our deck included replacing a number or boards and rebuilding a section of it, in addition to power washing, sanding, and staining. The finished deck looks great, as does the patio, where they power washed, relaid some of the stones, and applied polymeric sand. The cost of all this work was very reasonable. We'll definitely call on them again as needed."

"We hired Gerlyn to assemble and attach a 12 x 14 Yardistry Gazebo to our new cement patio. They also assembled and attached a privacy wall and counter to the Gazebo that we ordered along with our set. We could not be more pleased with the timeliness of the service and the friendliness of the builders. Very professional and detail oriented. Excellent communication. Would highly recommend."

FAQs for deck, fence, patio or porch clean and seal projects in Downers Grove, IL

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.
