"Robert and Jeff did an excellent job installing recessed lights and fans in 4 rooms amidst a crowded workspace as a crew of painters followed behind them and sometimes worked alongside them simultaneously. Robert was flexible and accommodating as I was initially indecisive with how many can lights were needed. He made helpful recommendations and also repaired a light that a handyman was unable to restore to working order. Robert's rates are reasonable and I appreciate how he has accommodated delivery delays. I will definitely continue to call on him for future projects!"

"Vendor responded quickly and gave a fair estimate. The job was completed in the time he indicated. However, the color of the stain was not as preferred. Also, the contractor likes to deal in cash/check directly to him rather than to a company name; I do not like doing that."

"I?m sad to write this review as Hero started off as a wonderful landscape partner to us with excellent communication and integrity. Unfortunately this past year we paid for a season pass of bi-weekly lawn mowing services plus an additional spring clean up service. We tried to work things out with Hero but ultimately we received fewer than half the lawn visits, no spring clean up and the visits we received were sporatic and not on the promised timeline. Hero agreed to come by with the refund for part of the services he did not provide but has since ghosted us despite consistent attempts to reach out by phone, text, Zelle and in-person. We lost $480 in services."

"We hired Spencer and Mitch because of them being so transparent, flexible and for being great communicators. When they encountered an unexpected situation with the roof replacement, they were quick to inform us and keep us in the loop about what our best options were. They provided pictures of the work they did and the previous photos before they started the work. Because of the great job they did, we will continue to use them for other work that our home requires. The work they did was clean and professional. If you’re thinking of using their company for any project, you will not regret it. These are down to earth people that will help you as best as they can given their multiple years of experience. "

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