"NuAgain cleaned and sealed our patio block deck in late July, 2025. It was a 2 day process. We were informed in a timely manner of each step of the process. The workers were very professional and did an excellent job in a timely manner. I recommend this company for your patio, deck and fence maintenance needs."

"Angel did an AMAZING job! He tore down an old pool deck and rebuilt an entirely new lower and upper deck, with 2 sets of stairs. From start to finish, working with Cassandra and Angel was easy. They kept constant communications and updates, kept the process moving, and were very knowledgeable when we had questions. Angel was timely, efficient and prompt; there were extremely hot or rainy days, where I thought it wouldn’t be possible to work in those conditions, but he made it work! I can’t praise them enough for their hard work and dedication to making our dream deck come true and making the process seamless. We had several quotes from competitors and the vibe of the others either didn’t understand what we wanted or just always tried to upsell. Minquiz came in with a reasonable & affordable quote that didn’t compromise what we envisioned. They made adjustments and recommendations to the plan as needed, with clear communication. We plan to hire them for future home projects!"

"All went well, until I needed him to contact me after the fence was installed. I needed a small addition to the bottom of one side and to one vertical corner where an opening was left. I have tried texting but he does not reply."

"Jose is one of the most careful, thorough, and caring service people I have ever encountered. He treated my home as if it was his own. He is honest and fair. I have more work to be done and I hired him again right away because of the above. Also his work ethic is phenomenal. If only he could train every other customer service personâ ¦ they have a lot to learn from him for sure!"

"We hired John to repair and repaint water-damaged drywall in 2 bathroom ceilings at our condo. John did an awesome job. The drywall looks like it never was damaged and the ceilings look like new. We knew when John came over to give us an estimate that we would hire him. He was prompt when he arrived on the first day. And he was meticulous about keeping the worksite clean from dust. We will rehire John for all of our interior painting projects."

FAQs for deck, fence, patio or porch clean and seal projects in Highland Park, 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.
