"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!"

"Haven Landscape did a great job. After they completed the project you would have never known that a trench and drains were installed in the yard. Everything was restored perfectly. They identified the problem and resolved the issue."

"Deck Doctor was the first person to give me an estimate on the work needed on my deck and the total cost. He was honest about the condition of my deck (it was actually in better shape than I thought and none of the wood needed replacing .... by the way, this is what the other deck contractors told me as well). When I hired him, he was able to accommodate my schedule and the work was done over the course of two days finishing sooner than I anticipated. Completed power washing and staining looks great! Highly recommended for your deck needs!"

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